An efficient modelling and hosting capacity analysis of a distribution system integrating PVs supported by the V2G technology

Over the past decade, the production of photovoltaic (PV) systems has increased owing to the rising demand for electricity generation. Recently, the vehicle-to-grid (V2G) technology of electric vehicles (EVs) has also gained interest as a clean and green energy source to support PVs providing sustainable energy. However, this necessitates the efficient modelling of PV output generation and V2G scheme for integration in the distribution system. Despite the advantages of PV and V2G technology, excessive integration potential affects the distribution system. To circumvent these problems, an accurate evaluation of hosting capacity (HC) is essential. This study proposes efficient modelling and a novel, improved analytical-optimal power flow method for HC analysis of distribution systems with PV and V2G integration considering uncertainties. Furthermore, the effects of increasing integration and optimal allocation of PVs and V2G technology on the voltage profile and power losses, respectively, were analysed. The IEEE 33-bus and 69-bus distribution systems were employed to perform the simulation test to obtain results of HC that validated the effectiveness and robustness of the proposed method compared with those of conventional methods. The proposed method provides an accurate, robust, and global-optimum solution. The integration of V2G technology enhances the overall HC of distribution system.

Numerical Expedition on the Potential of AgBiS2-Based Thin Film Solar Cells Employing Different Carrier Transport Layers.

In this study, a photovoltaic (PV) device has been developed by using AgBiS2 as the key material. The simulation of the photovoltaic cell has been performed using the SCAPS-1D simulator to analyze the impact of each layer. The design incorporates three window layers, CdS, In2S3, and ZnSe, alongside six familiar compounds, AlSb, CuGaSe2 (CGS), CuS, MoS2, Sb2S3, and WSe2, as the back surface field (BSF) layers. These heterostructures aim to uncover the potential of AgBiS2 in the realm of photovoltaic technology. When AgBiS2 functions within a singular heterojunction, specifically in configurations such as n-CdS/p-AgBiS2, n-In2S3/p-AgBiS2, and n-ZnSe/p-AgBiS2, the resulting values for open-circuit voltage (V OC) and the short circuit current (J SC) are found to be ∼0.90 V and ∼32 mA/cm2, respectively, while the corresponding power conversion efficiencies (PCE) are 23.56%, 22.60%, and 23.62%, respectively. On the contrary, the incorporation of various BSF layers like AlSb, CGS, CuS, MoS2, Sb2S3, and WSe2 results in a substantial increase in V OC, leading to an enhancement in PCE. Among the AgBiS2 based different dual-heterostructures, the outstanding PCE of 30.04% with a V OC of 1.12 V is achieved by n-ZnSe/p-AgBiS2/p+-Sb2S3 device. In comparison, the n-ZnSe/p-AgBiS2/p+-CGS structure exhibits a similar PCE of 30.03% with a V OC of 1.12 V. Additionally, the n-ZnSe/p-AgBiS2/p+-MoS2 arrangement demonstrates a PCE of 29.95% and a V OC of 1.12 V. The effective band alignments observed at the interfaces of ZnSe/AgBiS2 and AgBiS2/MoS2, ZnSe/AgBiS2 and AgBiS2/CGS, as well as ZnSe/AgBiS2 and AgBiS2/Sb2S3 contribute to a substantial built-in potential, leading to an elevated V OC. As an alternative to ZnSe, the CdS window could offer similar performances, whereas In2S3 might provide a lower efficiency. The elaborate simulation findings highlight the substantial potential of AgBiS2 as an absorber, particularly when coupled with different windows and BSF layers. This opens avenues for experimental research focused on AgBiS2 in the era of photovoltaic cells.

Investigating novel perovskites of lead-free flexible solar cell CH3NH3BiI3 and their photovoltaic performance with efficiency over 26%

Perovskite solar cells are increasing attention due to their unique characteristics in the field of photovoltaic technology. Lead-based perovskite solar cells are particularly notable for their high efficiency. However, their commercial production is limited because of the use of lead-based absorbers. As a result, research has shifted towards exploring lead-free alternatives in the realm of perovskite materials. This study utilizes SCAPS-1D simulation software to optimize the performance of a lead-free flexible solar cell. Lead (Pb), a group 14 element, is proposed to be replaced by bismuth (Bi), a group 15 element. We investigate how the selection of configurations for the Electron Transport Layer (ETL), Hole Transport Layer (HTL), and absorber layer impacts solar cell performance. This study represents a comprehensive examination of this material. The device optimization involves using a fluorine-doped tin oxide (FTO) substrate, cadmium sulfide (CdS), tungsten disulfide (WS2), titanium dioxide (TiO2), and fullerene (C60) as ETL components, methyl ammonium bismuth iodide (CH3NH3BiI3) as the absorber, molybdenum disulfide (MoS2) as the HTL, and platinum (Pt) as the electrode. In addition to optimizing ETL and HTL configurations, this study explores the effects of various factors such as absorber, ETL, and HTL thickness, shunt and series resistance, temperature variations, Mott-Schottky behavior, capacitance, recombination, generation rates, J-V characteristics, and quantum energy. The results show that the solar cell configuration using FTO/CdS/CH3NH3BiI3/MoS2/Pt achieves an efficiency of 26.60 %, a current density (JSC) of 32.02 mA/cm2, an open circuit voltage (VOC) of 0.974 V, and a fill factor (FF) of 85.24 %. This represents a significant improvement compared to previous research. This detailed simulation analysis enables researchers to develop cost-effective and highly efficient perovskite solar cells (PSCs), driving advancements in solar technology.

The paradox of permission: Why governments allow foreign actors to promote solar energy projects in disputed cities

This article examines why foreign actors promote rooftop photovoltaic (PV) projects in cities characterized by ongoing ethno-national conflicts, and why the host government accepts these projects despite viewing them as undermining its sovereignty. It finds that foreign aid providers increasingly view off-grid PV technology as a low-cost solution for helping the embattled minorities of the city strengthen their autonomy and self-sufficiency by disconnecting them from the state-controlled national electricity grid. Local authorities accept these projects because they view them as benign initiatives that can help them address ‘infrastructure vacuums’ in neglected spaces of the city. This allows foreign actors to shape the status quo of the disputed city while avoiding political pushback by the host government. This dynamic is examined in the case of East Jerusalem, where EU and UN bodies invested in rooftop PV projects over the past decade with the stated goal of strengthening the energy autonomy of the city's Palestinian neighborhoods and preserving the option of dividing the city's infrastructure in a future peace agreement. Through government protocols and interviews with foreign aid representatives who promoted the projects, Jerusalem municipal officials who approved them, and Palestinian users who installed them, this article finds that Israeli authorities viewed these projects as a necessary buffer to address ungoverned areas of the city where Palestinians viewed municipal integration projects as an act of occupation. Foreign actors introduced PV solutions to these areas but struggled to overcome technical, bureaucratic, and social hurdles that limited their progress.

Regulating TiO2 Deposition Using a Single-Anchored Ligand for High-Efficiency Perovskite Solar Cells.

Planar perovskite solar cells (PSCs), as a promising photovoltaic technology, have been extensively studied, with strong expectations for commercialization. Improving the power conversion efficiency (PCE) of PSCs is necessary to accelerate their practical application, in which the electron transport layer (ETL) plays a key part. Herein, a single-anchored ligand of phenylphosphonic acid (PPA) is utilized to regulate the chemical bath deposition of a TiO2 ETL, further improving the PCE of planar PSCs. The PPA possesses a steric benzene ring and a phosphoric acid group, which can inhibit the particle aggregation of the TiO2 film through steric hindrance, leading to optimized interface (ETL/perovskite) contact. In addition, the incorporated PPA can induce the upshift of the Fermi-level of the TiO2 film, which is beneficial for interfacial electron transport. As a consequence, the PSCs with PPA-TiO2 achieve a PCE of 24.83%, which is higher than that (24.21%) of PSCs with TiO2. In addition, the unencapsulated PSCs with PPA-TiO2 also exhibit enhanced stability when stored in ambient conditions.

In-situ synthesis of quaternary alkylammonium ligand capped organic-inorganic hybrid halide perovskite for high pure green luminescence in display application

This study delves into the intricate dynamics of ligand engineering for the synthesis of Methyl Ammonium Lead Bromide (MAPbBr3) nanocrystals (NCs), which exhibit immense potential in optoelectronic and photovoltaic applications. Our focus centres on the role of the quaternary ammonium molecule CTAB as a ligand in stabilizing MAPbBr3 NCs. This also addresses the challenges related to the stability and surface defects of NCs that hinder their commercial viability. Employing a modified ligand-assisted reprecipitation technique (LARP) with a dual solvent system, we optimized the CTAB concentration to 0.05 mmol, resulting in MAPbBr3 NCs with an impressive 88% quantum yield. XPS and FTIR analyses confirm the presence and binding of CTAB on the NC surface. The MAPbBr3-CTAB NCs exhibit higher exciton–phonon binding energy, enhancing their optical properties. Despite an unfavourable geometric fit, CTAB is effective in surface defect passivation due to its binding, solvation, and desorption energy during the dynamic binding process. 2D-DOSY NMR reveals approximately 66% CTAB bound to the NC surface. A comparative study involving MAPbBr3-OA, OLA, and MAPbBr3-CTAB deposited on LEDs demonstrates the superior performance of the latter, achieving a luminous efficiency of 42.18 lm W−1 at 1.2 ml deposition. These findings highlight the efficacy of CTAB in achieving high-purity green luminescence, aligning with BT.2020 display colour standards and paving the way for advanced optoelectronic applications. The successful synthesis and improved performance of MAPbBr3-CTAB NCs underscore their potential as a promising material for future optoelectronic and photovoltaic technologies.

Antena Tatasusun Grid Lut Sinar dengan Sel Suria Terpeka Pewarna (DSSC)

Wireless communication systems require electrical energy to operate and function. Whereas standalone applications require reliable power sources which can be realised by photovoltaic technology. Typically, photovoltaic cells and antennas are two separate devices. These devices compete for space in mobile or standalone systems, where available space is generally very limited. To address this issue, a combination of an antenna and a solar cell into a single device is needed. Integrating an antenna with a solar cell is challenging due to the importance of maintaining a compact, simple design while achieving optimal efficiency for both elements. This study focuses on designing a transparent grid array antenna integrated with Dye-Sensitized Solar Cells (DSSC) for Ku-band applications. The grid array design aims to improve antenna performance and is chosen for its suitability with the design and structure of the solar antenna device. The integrated antenna and solar cell were simulated using Computer Simulation Technology (CST) software at a frequency of 14 GHz for Ku-band applications. A prototype of the antenna and solar cell was fabricated, then tested and measured for the efficiency of both the antenna and solar elements. For the solar element, performance measurements were conducted using a halide lamp to mimic sunlight, with results presented in the form of current-voltage curves. In summary, by the end of this study, a transparent solar antenna for Ku-band applications was successfully designed with a gain exceeding 10 dBi. The solar cell’s performance showed an open-circuit voltage (V<sub>OC</sub>) of 0.6733 V, a short-circuit current density (J<sub>SC</sub>) of 2.06 mA/cm², a fill factor (f<sub>F</sub>) of 29.31%, and a power conversion efficiency (η) of 0.407%.

Interfacial modulation by ammonium salts in hole transport layer free CsPbBr3 solar cells with fill factor over 86 %

CsPbBr3-based perovskite solar cells (PSCs) are potential candidates for the next-generation photovoltaic technology owing to their robust stability. Nevertheless, the inorganic CsPbBr3 PSCs using carbon electrode without hole transport layer usually suffer from severe non-radiative recombination loss at CsPbBr3/Carbon interfaces, thereby generating low fill factors (FFs) and further limiting the improvement of power conversion efficiencies (PCEs). To circumvent this issue, we proposed a universal interfacial engineering strategy to reduce the trap-assisted recombination through depositing butylammonium bromide (BABr) on the surface of CsPbBr3 films, which would enhance the FF and subsequent PCE of inorganic PSCs. The experimental results illustrate that the BABr modification could not only improve the morphology and phase purity of the inorganic perovskite films, but also adjust the energy level alignment between the CsPbBr3 layer and carbon electrode. After the optimization of BABr concentrations, we fabricated the BABr-modified device delivered an impressive PCE of 9.86 % with an extreme high FF over 86 %, which is one of the highest values achieved among the reported inorganic PSCs. Moreover, the PCE of unsealed CsPbBr3 device with BABr exhibited almost no attenuation after 90 days storage under the ambient atmosphere.

Dynamic performance enhancement in 2D and 3D curved flexible photovoltaic modules: Mismatch loss analysis and cell interconnection configurations optimization

The integration of photovoltaic (PV) technology into curved-surface buildings holds promise for energy-efficient eco-cities. However, the surface irradiance field of curved PV modules is uneven, and the distribution varies with the relative position to the sun and the surface shape. In this study, the dynamic irradiance field distributions of 2D and 3D curved PV modules are investigated. Based on this, 3 PV cell interconnection methods are proposed in conjunction with the irradiance balance principle. The electrical performance and power loss mechanisms are analyzed, and the dynamic adaptability, orientation adaptability, and geometric adaptability are evaluated. The results show diverse irradiance field patterns under different central angle conditions: uniform distribution in the north-south or east-west direction, while Gaussian distribution in other directions. Appropriate PV cell interconnection methods for 2D curved PV modules can effectively reduce mismatch losses, demonstrating significant enhancement in power output, up to 1721.21 Wh and 1604.10 Wh respectively. However, for 3D curved PV modules, the 3 interconnection methods fail to effectively adapt to the dynamic variation in irradiance, thus unable to fully exploit the power generation potential. In-depth investigation of mismatch losses in this study contributes to improving the reliability and economic viability of curved PV module, promoting its commercial application.

Quasi-conformal monolithic n-i-p perovskite/c-Si tandem solar cells with light management strategies exceed 28 % efficiency

In the rapidly evolving field of photovoltaic technology, monolithic perovskite/crystalline silicon tandem solar cells (PSK/c-Si TSCs) have emerged as promising contenders, combining the advantageous properties of PSK with the recognized power conversion efficiency (PCE) of c-Si. Available studies have shown that in the field of PSK/c-Si TSCs, c-Si substrates can be categorized into: flat and pyramidal-textured structures. The limitation of flat structure lies in optical reflection losses, and the commercialization of large-scale pyramid structure is challenging to be compatible with conventional planar PSK solution processes. This study presents a novel quasi-conformal structure with dimensions between flat and pyramidal structures, which facilitates its seamless integration into PSK and c-Si production. Thermally evaporated bis(trifluoromethane)sulfonimide (TFSI)-doping 2,2′,7,7′-tetrakis(N,N-di-p-methoxyphenyl-amine)-9,9′-spirobifluorene (spiro-OMeTAD) has better conformal and electrical properties. The in-situ cesium-based PSK recrystallized-arrays (CPRA) growth scheme achieves current density matching of the two sub-cells by band-edge modulation of the wide-bandgap components. The champion PCE of CPRA-modified PSK/c-Si TSC is 28.53 %. The stability is enhanced due to the protective effect of the inorganic CPRA interface. This research exhibits the successful integration of novel structural elements and light management strategies, which are expected to have wider applications in solar energy harvesting.

The results showed that the PV grow lamp could simulate sunlight and stably output 455nm of light, which could improve the yield of flowers T1 (7.53%), quality T2 (15.40%) and potential T3 (30.28%), and the leaf length, plant height, plant protein and chlorophyll content were higher than those of normal growing plants. Therefore, solar photovoltaic grow lights can realize the conversion of sunlight, and expand the application range of photovoltaic power generation by converting them into analog wave frequencies through photovoltaic technology.
