Impact of Doping and Temperature on Heterojunction Silicon Solar Cell Performance (ZnO/a-Si/c-Si) : A Comparative Analysis Using COMSOL Multiphysics and SCAPS

This study investigates the effect of temperature, doping concentration and layer thickness on the performance of photovoltaic solar cells using COMSOL-Multiphysics and SCAPS programs as a means of simulation to see their performance towards these effects in the form of a comparative study between them, where we used a 1D heterogeneous solar cell (ZnO/a-Si/c-Si) We found through our analysis that in some cases SCAPS provides more stable values in some parameters, making it suitable for quick analysis without the need for complex calculations, while COMSOL shows more sensitivity to some variables such as temperature and layer thickness. If studying the effect of temperature and thin layers on performance is critical, COMSOL is more accurate in this aspect, as it gives more flexibility to model complex geometries and multiple physical interactions.Moreover, a comparison of the results obtained between COMSOL, SCAPS, and experimental results revealed that COMSOL results are more consistent with experimental results, making it a more reliable choice for modern solar cell design.
