Summary: The optical and electrical features of halide perovskites make them attractive for high-efficiency solar cell applications. Perovskite/silicon tandem solar cells have gained attention in the scientific community due to their higher efficiency compared to single-junction solar cells. The composition of perovskite materials can be engineered to improve their efficiency and stability. The impact of compositions on device output in different climate conditions is analyzed using an opto-thermal model. The optimal band gaps for bottom and top cells in tandem solar cells are investigated for realistic climate conditions. The results show that the compound MAPbBrI(2) with a band gap of 1.7 eV exhibits the best opto-electronic performance in tandem cells. The perovskite/silicon tandem cells perform thermally better than silicon solar cells, with a reduction in cell temperature and higher energy generation.
