“…Over the past decade, the photovoltaic (PV) market has seen a tremendous growth. While the annual installed PV capacity was still below 7 GWp in 2008, it reached 100 GWp in 2018 and this trend is expected to continue [1][2][3]. This evolution was enabled by a continuous increase in solar cell efficiencies [4] and cost reductions for solar cells and PV modules [1].…”

High temperature passivating contacts for c-Si based solar cells are intensively studied because of their potential in boosting solar cell efficiency while being compatible with industrial processes at high temperatures. In this work, the hydrogenation mechanism of fired passivating contacts (FPC) based on c-Si/SiOx/nc-SiCx(p) stacks was investigated. More specifically, the correlation between passivation and local re-distribution of hydrogen resulting from the application of different types of interfacial oxides (SiOx) and post-hydrogenation processes were analyzed. To do so, the applied processing sequence was interrupted at different stages in order to characterize the samples. To assess the hydrogen content, deuterium was introduced (alongside/instead of hydrogen) and secondary ion mass spectroscopy (SIMS) was used for depth profiling. Combining these results with lifetime measurements, the key role played by hydrogen in the passivation of defects at the c-Si/SiOx interface is discussed. The SIMS profiles show that hydrogen almost completely effuses out of the SiCx(p) during firing, but can be reintroduced by hydrogenation via forming gas anneal (FGA) or by release from a hydrogen containing layer such as SiNx:H. A pile-up of H at the c-Si/SiOx interface was observed and identified as a key element in the FPC's passivation mechanism. Moreover, the samples hydrogenated with SiNx:H exhibited higher H content compared to those treated by FGA, resulting in higher iVOC values. Further investigations revealed that the doping of the SiCx layer does not affect the amount of interfacial defects passivated by the hydrogenation process presented in this work. Eventually, an effect of the oxide's nature on passivation quality is evidenced. iVOC values of up to 706 mV and 720 mV were reached with FPC test structures using chemical and UV-O3 tunneling oxides, respectively, and up to 739 mV using a reference passivation sample featuring a ~25 nm thick thermal oxide.

“…Photovoltaics penetration in the energy mix is growing faster and globally. However, the PV landscape is foreseen to change, since while utility-scale PV systems have been dominating the market, distributed PV systems are becoming more relevant in many countries [1]. Thus, photovoltaic systems in buildings is an effective and sustainable means of producing renewable energy on site [2].…”

“…BIPV is the ideal solution for new buildings and retrofits [4], where PV modules play a constructive role in façades or roofs, but BAPV can be an interesting alternative for existing buildings not needing an envelope renovation. Both BAPV and simplified BIPV, using conventional PV modules with dedicated mounting structures, have experienced positive developments in numerous countries in 2019 [1].…”

“…As the most expensive component within a PV system is the solar cell itself [8], numerous methods are developed to optimise the energy produced from a single solar cell. This includes tracking systems which change the direction that the solar arrays face, to track the sun as it rises and falls over the course of a day and more advanced tracking systems are capable of multiple axis of movement to track seasonal changes in the suns location [9].…”

Mathematical Modelling of a Static Concentrating Photovoltaic: Simulation and Experimental Validation

et al. 2021

For the past twenty years, there has been increasing interest and investment in solar photovoltaic (PV) technology. One particular area of interest is the development of concentrating PV (CPV), especially for use in building integration. Many CPV designs have been developed and investigated. This paper aims at producing a mathematical modelling using MATLAB programme to predict the current-voltage (I-V) and power-voltage (P-V) characteristics of a static CPV. The MATLAB programme could also simulate the angular response of the CPV designs-which has never been explored in the previous literature. In this paper, a CPV known as the rotationally asymmetrical dielectric totally internally reflecting concentrator (RADTIRC) was analysed. A specific RADTIRC design that has an acceptance angle of ±40° was investigated in this paper. A mathematical modelling was used to simulate the angular characteristics of the RADTIRC from −50° to 50° with an increment 5°. For any CPV, we propose that the value of opto-electronic gain, Copto-e needs to be included in the mathematical model, which were obtained from experiments. The range of incident angle (±50°) was selected to demonstrate that the RADTIRC is capable of capturing the sun rays within its acceptance angle of ±40°. In each simulation, the I-V and P-V characteristics were produced, and the short circuit current (Isc), the open-circuit voltage (Voc), the maximum power (Pmax), the fill factor (FF) and the opto-electronic gain (Copto-e) were determined and recorded. The results from the simulations were validated via experiments. It was found that the simulation model is able to predict the I-V and P-V characteristics of the RADTIRC as well as its angular response, with the highest error recorded for the Isc, Voc, Pmax, FF and Copto-e was 2.1229%, 5.3913%, 9.9681%, 4.4231% and 0.0000% respectively when compared with the experiment.
