Abstract

Perovskite based tandem solar cell topologies have garnered a lot of interest in the field of photovoltaic for surpassing the single-cell efficiency limit and achieving the power conversion efficiency (PCE) beyond 30%. However, the PCE as well as stability of tandem solar cells may severely affected by the optical and electrical mismatching and choosing the wrong carrier transport materials, thus it is important to be optimized the active layers’ parameters for achieving optimum performance. In this study, the SCAPS 1D device simulation tool was utilized to optimize a highly efficient lead-free perovskite-perovskite tandem solar cell (PPTSC). The absorber material in the tandem structure was Cs2AgBi0.75Sb0.25Br6 (Eg = 1.80 eV) in the top cell and FAMASnGeI3 (Eg = 1.40 eV) in the bottom cell. The optimized device shows a promising PCE of 28.87% with high Voc of 2.08 V. The significant impact of device temperature has also been investigated and the temperature gradient found to be -0.098%/oC. We believe that the proposed device has enormous potential for the fabrication of a highly efficient PPTSC, and achieving successful commercialization.
