In this work, aims to delve into the complex dynamics of recombination within CdTe devices, and elucidate roles played by front interface, back interface and Shockley-Reed-Hall (SRH), the dominant recombination pathways within the cells. Temperature dependent measurements and simulations has been used in identifying these roles. Here, with the help of SCAPS-1D simulation software, we have explored how and what recombination machinimas affect the device performance the most. In particular, we have kept one interface limiting at a time, and electrical parameters of layers and interfaces varied and checked how recombination current densities varies at different temperatures. By doing so, we aim to understand the interplay between temperature and recombination in CdTe devices and contribute to the ongoing efforts in the photovoltaic community to push the boundaries of CdTe technology for the next generation of high-efficiency solar energy conversion. |
