Single junction crystalline silicon (c-Si) solar cells are reaching their practical efficiency limit while perovskite/c-Si tandem solar cells have achieved efficiencies above the theoretical limit of single junction c-Si solar cells. Next to low-thermal budget silicon heterojunction architecture, high-thermal budget carrier-selective passivating contacts (CSPCs) based on polycrystalline-SiO (poly-SiO ) also constitute a promising architecture for high efficiency perovskite/c-Si tandem solar cells. In this work, we present the development of c-Si bottom cells based on high-temperature poly-SiO CSPCs and demonstrate novel high-efficiency four-terminal (4T) and two-terminal (2T) perovskite/c-Si tandem solar cells. First, we tuned the ultra-thin, thermally grown SiO . Then we optimized the passivation properties of p-type and n-type doped poly-SiO CSPCs. Here, we have optimized the p-type doped poly-SiO CSPC on textured interfaces via a two-step annealing process. Finally, we integrated such bottom solar cells in both 4T and 2T tandems, achieving 28.1% and 23.2% conversion efficiency, respectively.

Salt hydrates are promising candidates for the long-term thermochemical heat storage (TCES) in the building environment. In such storage systems, the surplus of energy will be exploited in an endothermic reaction to dehydrate the salt hydrates. Once it is demanded, the stored energy will be released through an exothermic reaction by hydrating the salt, which results in an increase in the mass and temperature of salt particles as well as changes in the species of material. In order to construct an improved storage system, it is very important to deeply investigate the details of the (de)hydration processes in salt hydrates. Poor heat and mass transfer is the bottle neck in this technology. Therefore, the main objective of this work is to investigate how heat and mass transfer influence the (de)hydration in a closed TCES-system. The novelty of this work is to provide a high degree of detailed information about (de)hydration of TCM (thermochemical material) in a bed by calculating transport phenomena for each single particle while considering their interactions with each other. This is achieved by applying and developing the Extended Discrete Element Method (XDEM) as a numerical modeling tool and Thermogravimetric Analysis (TGA) measurements. Comparisons are carried out for the results of the hydration and dehydration process in a single particle with the measurements which shows a very good agreement. Moreover, impact of particle size on the hydration process is also studied. Further, simulations for the hydration process in a chain of six potassium carbonate (K2CO3) particles are performed in order to understand the mechanism of heat and mass transfer inside the packed beds.

Thermochemical materials K2CO3, MgCl2 and Na2S have been investigated in depth on energy density, power output and chemical stability in view of domestic heat storage application, presenting a critical assessment of potential chemical side reactions in an open and closed reactor concept. These materials were selected based on a recent review on all possible salt hydrates, within the frame of a thermochemical heat battery and considering recent advances in heat storage application. Judged by gravimetric and calorimetric experiments in operating conditions and worst-case-scenario conditions, K2CO3 is recommended for both an open and closed system heat battery. The compound is chemically robust with a material level energy density of 1.28 GJ/m3 in an open system and 0.95 GJ/m3 in a closed system, yielding a power output of 283–675 kW/m3. Na2S and MgCl2 on the other hand are chemically not robust in heat storage application, although having a higher energy density, output power and temperature in one cycle.

A literature review is performed in order to collect and analyse the thermodynamic data of an utmost number of salt hydrate reactions (i.e., 563 reactions are reviewed). These data allow us to evaluate the theoretical possibilities and limitations of salt hydrates as thermochemical materials (TCMs) for seasonal heat storage in the built environment (1GJ/m3 on system level). Two filters are used for evaluation. Filter 1 including three criteria i.e., an ideal hydration reaction with a capacity larger than 2GJ/m3, a hydration temperature of 65°C (suitable for domestic hot water) or higher, a dehydration temperature below 100°C to profit as much as possible from the solar heat that can be harvested. Only four of the studied hydrates fit with these demands. For selecting a larger number of hydrates, a second filter is introduced with less demanding constraints. It is expected that modifications on heat storage system level are needed to reach an acceptable system performance with the hydrates selected through filter 2 (hydration reaction with a capacity larger than 1.3GJ/m3, a hydration temperature of 50°C or higher, a dehydration temperature below 120°C). Based on this filter, a shortlist of 25 TCM hydrate reactions are identified, including the four of filter 1. The shortlist is analyzed by considering price, chemical stability, reaction kinetics and safety for domestic environment. Based on this additional analysis with the used constraints, K2CO3 is determined to be the most promising candidate for open or closed systems, but has a low energy density. Based on the review of 563 hydrate reactions, we concluded that no ideal salt exists for seasonal heat storage under the considered boundary conditions. With the current concept of seasonal heat storage, including closed and open systems, whereby only one dehydration cycle per year is performed under a system energy density of 1GJ/m3, it is not realistic for large scale implementation to use pure salt hydrates as heat storage material. By adjusting the constraints, such as multiple cycles per year or higher water vapor pressures, salt hydrates can still be used as TCMs. It should be mentioned that MgSO4·7H2O, MgSO4·6H2O and CaCl2·6H2O are not listed in our shortlist of 25 TCMs, although these hydrates are commonly suggested in the literature as promising TCM for seasonal heat storage. The present study on pT-characteristics shows, however, that these salts are not fitting the demands of such a heat storage system.

A responsive release system consisting of biocide encapsulated by the hydrophobic protein zein was investigated, in which a biocide will be released if growth of micro-organisms occurs. Because biocide release is difficult to detect, a model system using dyes with different size, polarity and charge was developed first to study the applicability of the zein matrix as an enzyme triggered responsive release system. The responsive release efficiency was highest for dyes with a positive charge, that have limited flexibility and the possibility of aromatic interactions with the matrix. The positively charged dyes showed a larger effect than negatively charged dyes. Additives were shown to enhance the release efficiency of the system. The most efficient release system combines the dye methyl violet with the additive oleic acid. These compounds interact to form a larger, more hydrophobic moiety. A plasticizing effect is thought also to be important, since even without clear specific interactions between dye and additives, release properties are enhanced. The charge of the additives seemed to be more important than their size, and both hydrophobic and ionic interactions were shown to play a role.

The calorific value of energetic gasses is an important parameter in the quality assessment of gas steams, and can be calculated from the chemical composition of the gas. An array of capacitive sensor electrodes was developed, each functionalized with a gas responsive coating to measure the concentration of methane, ethane, propane, carbon dioxide, water and nitrogen in various gas mixtures. Using the data from six functionalized chips, the calorific value could be measured with 5% accuracy. Part of this error is caused by the noise in the electronics, another part by the non-linearity of the responsive coatings. Future developments aim at improving the response of the coatings and a higher integration of electrodes and will lead to a higher sensitivity and an expected accuracy of 0.5%. The sensor should be implemented in flow equipment, restricting the size to several cubic centimeters.

The functionalization of optical fibers containing Fiber Bragg Gratings is a very interesting approach in the development of distributed chemical sensors. We have shown a large variety of coatings, ranging from polymers to ceramics as responsive layers for the detection of many chemical species. Some coated fibers can be applied in extreme conditions, where the presence of oil, water or gaseous hydrocarbons needs to be monitored. Others can be very accurate in the detection of salt concentrations, pH or relative humidity in very small spaces. The small size (250 μm in diameter) is one of the advantages of these types of sensors, together with the multiplexing ability, and absence of electronics.

This workstudies the impingement on the rim of acetabular liner due to wear on the surface of acetabular liner using finite element simulation. A three dimensional contact model between a femoral head and an acetabular liner was developed. There are three steps in this simulation, i.e. creating the virtualwear on the surface of acetabular liner, applying the load at the femoral head, and rotating the femoral head from neutral position till the impingement occurrence. The virtualwear is created based on the data of wear depth which was obtained from literature. Results showed that the wear on the acetabular liner surface wouldaffected the impingement occurrence, in which the impingement angle becomes narrow. In addition, the failure possibility of the acetabular liner rimwould become higher.

Fixation of acetabular cup to bone material is an important initial stability for artificial hip joint. In general, the fixation in cement less-type acetabular cup uses press-fit and screw methods. These methods can be applied alone or together. Based on literature survey, the additional screw inside of cup is effective; however, it has little effect in whole fixation. Therefore, an acetabular cup with good fixation, easy manufacture and easy installation is required. This paper is aiming at evaluating and proposing a new cup fixation design. To prove the strength of the present cup fixation design, the finite element simulation of three dimensional cup with new fixation design was performed. The present cup design was examined with twist axial and radial rotation. Results showed that the proposed cup design was better than the general version.
