This study evaluates the device performance of using CH3NH3PbI3 perovskite as top sub-cells in tandem solar cells, finding that optimizing thickness and doping concentration can improve device performance and tandem efficiency.
A device based on perovskite and silicon tandem solar cells is considered as an interesting route to improve cell efficiency further the limit of single junction by keeping the reasonable cost of production. Here, we assess the device performances of CH3NH3PbI3 perovskite as top sub-cells in tandem solar cells in association with traditional crystalline silicon heterojunction solar cells of various configurations such as monolithic two terminals, four terminals mechanically stacked, and four-terminal optically coupled perovskite/Si tandem solar cells. Our simulation findings highlight that the suggested architecture design increases the device performance by optimizing the thickness of perovskite. Furthermore, the optimal doping concentration of perovskite (10(18) cm(-3)) has contributed to achieve high tandem efficiencies of various device configurations.
