Solar energy has grown in popularity in recent years. Conventional solar panels cannot provide enough energy to meet consumer demand. Therefore, more solar panels are needed to meet consumer demand. The Internet of Things (IoT) Solar Tracker maximises solar energy collecting by connecting the physical and digital worlds. This study integrates IoT to improve solar tracker performance. Blynk uses the NodeMCU ESP8266 control unit to monitor voltage, current, and power usage. This research uses the Arduino IDE, a photoresistor sensor, and a current sensor, INA219. This work advances solar energy efficiency. By comparing solar panel electrical qualities in different environments, this research succeeded. To assess solar panel efficiency, 5 V and 12 V fans were used as loads. The results demonstrated that load configuration deliberately influences power and energy production. Solar panels produced greater power and energy under 12 V fan loads than 5 V loads. This observation assists solar energy system analysis and design.

An Emergent Integrated Technology: Solar-Assisted Redox Flow Batteries

Over the last several years, the use of energy from renewable energy sources is becoming urgent in order to decrease fossil fuel demand and large CO2 emissions. Among all renewable energy sources, the sun is probably the most exploitable and limitless resource. However, the intermittent nature of the sunlight makes imperative the development of efficient energy storage devices to store the electricity generated from solar irradiation. In this context, solar flow batteries (SFBs) have been proposed as an attractive technology for sunlight harvesting and storage into electrochemical fuels. The photoelectrodes integrated in the photoelectrochemical cell (PEC) promote the photocharging of the redox couples in the liquid electrolytes, storing the photogenerated electrons or holes as chemical energy, which can be then discharged in electricity. It is expected that the solar battery is able to be charged under sunlight without needing an external supply. The integrated SFBs show some advantages with respect to the non-integrated devices, such as i) safe performance of the photoelectrode because of the recirculation of the electrolyte and, ii) cost-effective production due to their compact design and iii) allow co-generation, i.e. heat up the electrolytes for sanitary/thermal comfort applications [1][2]. Nevertheless, the development of unbiased and high-efficient SFBs requires finding the optimal voltage match between the photoelectrode and chemical redox pair. In this communication, it is shown recent advances in SFBs by exploring low-cost, environmentally friendly, Earth-abundant, and non-toxic materials for the decentralized solar energy collection, storage, and utilization. In particular, photoelectrodes based on nitrides and oxides have been studied in combination with aqueous and non-aqueous electrolytes. Special attention has been paid to the shape and morphology of the semiconductors and how it affects to the efficiency of the PEC cells. In parallel, the stability and the efficiency of the semiconductors have been also characterized in different electrolytes, aqueous-based and using organic solvents. It is shown how the nature of the electrolyte directly influences the performance of the semiconductors regardless the photovoltage and the photocurrents, which are crucial parameters for improving the performance of the overall SFBs. In addition, the research efforts are not only in the field of materials, but also on the engineering challenges of device architectures. It is proposed to develop a membrane-free SFB in which the charge transfer process takes place at the liquid-liquid interface [3]. The research shown in this work has been carried out in the framework of a European project and an international collaboration with the University of Porto, Portugal.

BUILDING HEAT SUPPLY SYSTEM BASED ON HYBRID SOLAR COLLECTORS

Increasing the efficiency of solar heat supply systems is one of the important problems of solar energy. The research presented in this article is aimed at improving the efficiency of hybrid solar collectors without a transparent coating for building heating systems. One of the key challenges in the field of solar energy is the development of new technologies to ensure high collection of solar energy and to integrate it into traditional heating and hot water systems. The study shows that hybrid solar collectors with the placement of heat carrier circulation circuit tubes above the heat absorber can increase the thermal efficiency factor with a certain change in the angle of inclination and the density of solar radiation. A nomogram was also developed that determines the dependence of this coefficient on the angles of arrival of solar radiation and its density.

Effect of tin concentrations on the elemental and optical properties of zinc oxide thin films

Pure zinc oxide and Sn-doped ZnO thin films were deposited on a pre-heated glass substrate from tin (II) chloride dihydrate (SnCl2.2H2O) and zinc acetate (Zn(CH3COO))2 precursors using spray pyrolysis technique. The doped films were achieved by adding various quantities of (SnCl2. 2H2O) precursor to the solution of zinc acetate in volume percent range of 0–10. Rutherford Backscattering Spectrometry (RBS) was used to characterise the prepared films to determine their thickness and elemental composition. To examine the films' optical characteristics, a UV spectrometer operating at room temperature and covering a wavelength range of 300–1100 nm was employed. The film's thickness and composition show that as the volume of Sn in the thin films increases, so does the film's thickness. With average transmittance values up to 70 %, all the films are quite transparent in the visible region of the electromagnetic spectrum and have a significant UV cut-off at roughly 380 nm. The reflectivity of Sn-doped ZnO films is seen to be independent of the volume of Sn in the films, and the reflectivity of the films diminishes as the wavelength increases. Sn-doped ZnO thin film has an optical band gap of 3.14–3.18 eV. The properties of the thin film produced make it suitable for solar energy collection and improve the efficiency of solar energy system, various optoelectronics devices and sensor.

Mixed Convection in a Lid-Driven Cavity in the Presence of Magnetic Field with Sinusoidal Heating

Understanding mixed convection in engineering applications such as heat exchangers, electronics cooling devices, and solar energy collectors have urged researchers to investigate this phenomenon deeper. This study investigates the fluid flow and heat transfer pattern in a two-dimensional (2D) rectangular cavity with sinusoidal heating on the moving top lid numerically. The bottom wall is kept cool while the vertical walls are insulated. The effect of Hartmann number, Ha on the thermal characteristics and fluid flow are analyzed for Richardson number, Ri=1 which indicate mixed convection dominated regime. The governing equations are solved numerically using a SIMPLE algorithm with the finite volume method. The numerical results are displayed in streamlines and isotherms plots. The value of the Nusselt number indicating the heat transfer rate is also discussed. It is found that Ha has a significant effect on the heat transfer process and fluid flow. It can be seen clearly when the value of Ha=30, the rate of heat transfer dropped significantly on the cold wall. Generally, the heat transfer rate decreases with the increase of Ha.

Light-driven phase change microcapsules modified by TiN/CNTs nanocomposites for enhancement of solar energy storage and solar photocatalytic efficiency

The development of microencapsulated phase change materials (PCMs) integrating solar photothermal conversion and storage holds significant for solar energy utilization. Herein, this study developed an efficient light-driven phase change microcapsule system by encapsulating paraffin within a brookite TiO2 shell through sol-gel interfacial polymerization, followed by wrapping titanium nitride (TiN)/carbon nanotubes (CNTs) nanocomposites on the shell surface. The microcapsule system exhibited a regular spherical core-shell structural morphology. The encapsulation of TiO2 and the introduction of the highly thermal conductivity enhancement phase increased the thermal conductivity of the microcapsule system by approximately 151.5 % compared to pure paraffin while maintaining latent heat of over 135 J·g−1. Furthermore, TiN/CNTs were combined with the microcapsule shell through hydrogen bonds and shared electron pairs, constructing localized surface plasmon resonance (LSPR)-enhanced heterojunction. The microcapsule system demonstrated excellent broad-spectrum light absorption capacity, resulting in a remarkable 112.01 % enhancement in the optimum photothermal conversion efficiency. Concurrently, the degradation rate of MB was increased by 59.52 % due to the synergistic catalytic action of photothermal, semiconductor, and LSPR effects. The microcapsule system also exhibited excellent thermal and cycling stability, with only 1.6 % latent heat loss after 500 thermal cycles. This study provides a promising strategy for developing energy storage microcapsule composite PCMs for the efficient collection and utilization of solar energy.

Thermal investigation and parametric analysis of cascaded latent heat storage system enhanced by porous media

Cascaded latent heat storage (CLHS) has become a promising solution to the recovery and utilization of thermal energy. Many studies optimized the inlet temperature and velocity of heat transfer fluid to improve the heat transfer rate for the charging process of CLHS systems with pure phase change materials (PCMs), but the effect is not significant, mainly because the thermal resistance of the system comes from the PCMs side due to the low thermal conductivity of pure PCMs. Porous media composite phase change materials (CPCMs) have been shown to have promising prospects in a single PCM system, but no research precedent has been found for the application of porous media CPCM in the CLHS system. Besides, when CPCMs are encapsulated in the cavities of the CLHS system instead of pure PCMs, the difference in the degree of impact between the porosity of a porous media and boundary conditions on the thermal performance of a CLHS system is still unclear. The purpose of this article is to significantly improve the heat transfer rate by applying the CPCM to the CLHS system and to comprehensively compare the impact of porosity and HTF inlet boundary conditions on the charging/discharging time and energy/exergy charged/discharged rates of a CLHS system with CPCMs through two sensitivity analysis methods. When the porosity reduces from 0.97 to 0.92, the charging time and the discharging time decrease by 74.50 % and 73.39 % respectively; the average energy charge rate and average exergy charge rate increase by about 4.11 times; the average energy and exergy discharge rates increase by 5.76 times and 5.8 times respectively. Sensitivity analysis shows that the porosity of a porous media is the most important factor affecting the charging and discharging rates of a CLHS system, but its impact on energy and exergy charge/discharge rates is not monotonic. The effect of the inlet temperature and velocity of the HTF on a CLHS system is complex, and simply changing a single variable may not be effective in optimizing thermal performance parameters. This study provides a comprehensive performance enhancement strategy for the thermal energy storage and utilization processes of CLHS systems, which have great potential in fields such as solar energy collection, waste heat recovery, and building heating.

The main results reveal that isothermal and concentration lines are significantly more distorted, indicating intensified concentration and temperature distributions because of the growth of baffle length (L). Nuave decreases by 8.4% and 0.8% while it enhances by 49.86% and 33.87%, respectively, because of growth in the L from 0.1 to 0.2 and 0.2 to 0.3.Originality/valueSuch a comprehensive study on the second law and thermal behavior of DDNC of Al2O3-H2O nanofluid within a C-shaped cavity emplacing two hot baffles and impacted by magnetic field has not yet been carried out.

SYSTEMATIC REVIEW OF SOLAR PHOTOVOLTAICS AND AUTOMOTIVE APPLICATIONS

Photovoltaic (P.V.) solar cells convert sunlight into electricity. The conversion of available sunlight to electricity leads to investigations focused on technologies that reduce reliance on fossil fuels and reduce carbon emissions. Investigative work in this area leads to several improvements, increasing efficiencies, cleaner processes, new materials, and reduces cost. With increasing awareness and growing need for sustainable development, P.V.'s have made their way into various applications in the Energy, Industrial, Commercial, Residential, and Transportation sectors of the world. The migration of P.V.’s is reducing reliance on fossil fuels for energy while combating carbon emissions and climate change. The oil embargo of the 1970s led many governments and researchers to investigate alternative and cleaner technologies of vehicle propulsion in the transportation industry, including hydrogen, ethanol, natural gas, methane, and various forms of electric vehicles (E.V.'s). Of these technologies, electric vehicles have gained popularity in the market with improvements continuing to advance the field in energy efficiency, storage, and management with a potential of energy generation using P.V.'s mounted to vehicles. The utilization of vehicle integrated P.V. solar cells presents possibilities for improving the range of electric vehicles demonstrated throughout various solar race challenges worldwide. Many of these solar electric vehicles (S.E.V.'s) were on the individual, research-based scale, and little use of this technology has made it to market vehicles. Further improvements and investigations in P.V. and E.V. technology continue to improve consumer level adoption to address their challenges and limitations. As a result of examining these facts, the researchers present a summary systemic review of existing research on the use of solar energy to power an automobile. It will lightly cover solar energy collectors and then provide a more in-depth examination of existing literature.

Efficient visible light performance of MoS2QDs/TiO2 hollow sphere photocatalysts for the degradation of dyes and antibiotics

In this paper, molybdenum disulfide quantum dots (MoS2QDs) and TiO2 nanoparticles were used as visible light-responsive photocatalysts. The intensity of the bandgap photoluminescence of quantum dots was reduced after combining MoS2QDs with TiO2. This indicates that the photoexcited electrons in MoS2QDs are easily transferred to TiO2. The combination of MoS2QDs and TiO2 inhibits the recombination of charges and the complexation of photogenerated carriers, thus improving the degradation efficiency of dyes and antibiotics in the photocatalytic process. The cycling results showed that the MoS2QDs/TiO2 composites had good cycling stability. After five cycles of experiments, the composites still maintained similar degradation activity. Finally, a possible mechanism of the photocatalytic reaction of MoS2QDs/TiO2 is proposed. The charge generation and electron-hole separation capability of MoS2QDs/TiO2 in a wide spectral range can effectively separate photogenerated electron-hole pairs and maintain its high redox capability. It provides a broad prospect for composite materials to improve photocatalytic activity in different fields and offers many new possibilities for solar energy collection systems.

AutoGIS processing for site selection for solar pond development as efficient water treatment plants in Egypt

The increasing demand for renewable and environmentally friendly energy sources is a top priority for many countries around the world. It is obvious that renewable solar energy will help to meet most of the energy demand in the coming years. A solar pond is a huge Salt artificial Lake that serves as a solar energy collection system. However, site selection is a critical factor that affects the effectiveness and lifetime of a solar pond. Here, we present an innovative methodology for site selection based on three environmental factors, including direct solar irradiance (DNI), temperature, and wind speed. Our approach uses Python programming and clustering analysis with several libraries, including Pandas, Geopandas, Rasterio, Osgeo, and Sklearn, to analyse and process data collected over a 30-year period from NASA power. This method was applied to the geographic boundaries of Egypt, but the methods can be applied to any spatial context if the same dataset is available. The results show that Egypt has a potential land area of 500 km2 suitable for solar ponds construction along the border with Sudan throughout the year, including 2000 km2 in winter (between January and March), 800 km2 in spring (between April and June), 900 km2 in summer (between July and September), and the largest area of 3700 km2 (between October and December), most of which is located in the south of the Eastern Desert and around the Nile River. Notably, the northwestern region, close to the Mediterranean Sea on the border with Libya, exhibits suitability for solar pond development, with consistent performance throughout the year. Our results provide an efficient way for GIS and data processing and could be useful for implementing new software to find the best location for solar ponds development. This could be beneficial for those interested in investing in renewable energy and using solar ponds as an efficient water treatment plant.

The present study estimate and investigate the variation of albedo for Maiduguri situated in the Sahelian region of Nigeria, using meteorological data of global solar radiation obtained from the National Aeronautics and Space Administration (NASA) extending for a period between 1984 to 2021. Investigation was carried out on the variation of albedo with surface temperature, maximum wavelength, clearness index, global solar radiation, relative humidity and mean temperature. The study found that the estimated surface albedo exhibited a direct opposite relationship with the clearness index, an inverse relationship with the emitting Earth’s surface temperature and a direct relationship with the wavelength for the location. The highest value of 0.5125 and lowest value of 0.3344 were found in August and November respectively. The emitting Earth surface temperature ranged between 232.8674 K in August and 251.7177 K in November. This is in agreement with the standard emitting Earth surface temperature (255.0000 K). The values of the maximum emitting wavelength were found to be > 4 indicating longwave radiation which is within the infrared region of the electromagnetic spectrum. The results from this study will be useful for the design of solar energy collectors and researches on atmospheric radiative transfer.

Ultra-broadband solar energy absorber based on Ti and TiN from visible to mid-infrared

In this work, a metamaterial absorber based on titanium (Ti) and titanium nitride (TiN) is proposed. Theoretical calculation by finite-difference time-domain (FDTD) method shows that the absorber could achieve a bandwidth of 3720 nm in the spectrum range of 280 nm − 4000 nm. The average absorptivity of the absorber can reach 96.9%. The physical mechanism of the absorber is analyzed from the impedance matching theory and electromagnetic field distribution. Furthermore, simulation results illustrate that the absorber is polarization-insensitive and allows a wide range of incident angles. The absorption spectrum is basically consistent with that of air mass 1.5 (AM1.5). And it can achieve high thermal conversion efficiencies over a wide range of temperatures. These results indicate that the absorber has a good development prospect in solar energy collection.

A wind-solar energy harvester based on airflow enhancement mechanism for rail-side devices

A significant challenge arising from the rugged climate and environment is the provision of power to isolated railway-side equipment on the Plateau. Emerging renewable energy harvesting technologies present a promising solution. This paper proposes and confirms a Wind-Solar Energy Harvester (WSEH) founded on an Airflow Enhancement Mechanism (AFEM) for powering rail-side equipment. The proposed WSEH comprises of Vertical Axis Wind Turbine (VAWT), Flexible Photovoltaic Deflectors (FPVDs), and energy conversion and storage devices. The AFEM is executed founded on the FPVD that amplifies the airflow energy blown towards the VAWT due to the Blockage effect. The FPVD, grounded on an umbrella-like mechanism, unfolds as a PV panel for solar energy collection; and folds as a deflector to raise the wind energy collection potential for the VAWT. Through CFD simulation, the VAWT’s maximum power coefficient attains 0.387, and the optimum gain effect of FPVD is 66.54%. The prototypes, comprising VAWT and FPVDs, are scrutinized in a wind tunnel to authenticate the practicable effects illustrated by the no-load speed and load output of VAWT. The case study demonstrates that the WSEH creates 1566.82 kWh of electrical energy per year, sufficient for powering rail-side equipment on the Plateau.

Decision support model for PV integrated shading system: Office building case

Office buildings have a high amount of internal heat, solar gain, daytime energy consumption and occupancy schedules. Therefore, the increment in the cooling energy demand highlights the shading systems to provide efficient energy retrofit for office buildings. Shading surfaces, to prevent the high amount of solar radiation, are suitable for the collection of solar energy and the integration of photovoltaic systems onto the building envelope. However, the impact of the shading surface on the cooling, heating, and lighting energy consumption and the amount of energy produced by the PV system is a great task as a decision-making problem with multiple independent and dependent variables. This study searches for the installation of a PV integrated shading system to an office building through a decision support methodology. Independent variables such as the shading surface area, and angle and the dependent variables such as the energy, embodied carbon, and cost indicators are analysed within the decision support methodology. The results provide a definitive structure for such decision-making problems. Moreover, findings highlight that although Mono-Si PV options are more efficient in terms of energy generation, Poly-Si PV options are found to be the ideal solutions, due to the lower cost and embodied carbon.

Phenomenon of courtyards being roofed and its significance for building energy efficiency

Courtyard building is an important type of vernacular architecture, widely distributed in different climate zones around the world. Traditionally, courtyards are characterized by opening to the sky, providing buffer spaces for ventilation and light for the surrounding buildings. However, in Hebei, China, local buildings are showing an evolution trend characterized by the courtyards being roofed (CBR). This spontaneous evolution presents the diversity of CBR technologies (CBRTs), including light-transmitting CBRTs (T-CBRTs) and non-light-transmitting CBRTs (NT-CBRTs). Based on field measurements and simulation technology, the improvement effect of CBR on building energy efficiency (EE) is analyzed, and the EE of different CBRTs is compared. The results show that, T-CBRT and NT-CBRT can reduce the annual total energy consumption of open courtyards by 19.97% and 15.41% respectively without upgrading the original envelope structure. The analysis of the impact mechanism shows that CBRT increases the temperature of the courtyard and the room by improving the solar energy collection efficiency and expanding the heat storage space, which effectively reduces the heat leakage caused by the envelope and ventilation, and shortens the heating time. The light transmittance of the roof material is the most critical parameter affecting the EE of T-CBRT, and the roof height largely determines the performance of NT-CBRT. Multi-layer glass or concrete panels are not the best choice for CBRT roofing materials, and plastic films or polycarbonate sheets with high light transmittance and anti-aging are recommended. CBR is considered as a promising development direction because it can reduce the economic burden of energy consumption for local farmers by improving the EE of buildings.
