| Popis: |
Hybrid halide perovskites (HHPs) based solar cells are currently under intense investigation as the solar cells based on these materials show extraordinary power conversion efficiencies exceeding 22 % with unusual characteristics. Through first-principles pseudopotential calculations, we have investigated the structural, electronic and optical properties of Pb-based HHP, HC(NH2)2PbI3 (FAPbI3) and analyzed the effect of incorporating inorganic Cs+ at formamidinium (FA+) cation site. Our results exhibit that 12.5% of Cs-doping not only increases the optical performance of FAPbI3 solar cell absorbers by enhancing the absorption coefficient but also provides the stability to the absorber material, making it a promising candidate for highly efficient and stable perovskite solar cells. |
