Abstrakt: The performance of perovskite solar cells (PSCs) can be greatly influenced by light absorption layer modification. In this study, a new strategy that employs CdxSn(1−x)S alloy materials as sensitizers is put forward to address the drawbacks of single-component sensitizers. The study demonstrates the addition of CdxSn(1−x)S into the perovskite precursor solution to co-sensitized solar cells via one-step spin coating. The compactness and crystal size of the perovskite film were significantly improved after incorporating CdxSn(1−x)S alloy into the CH3NH3PbI3 (MAPI) solution to form the MAPI/CdxSn(1−x)S precursor solution. Furthermore, the charge transfer of resulting PSCs is observably improved. Consequently, the photoelectric conversion efficiency (PCE) of PSCs was increased to 5.84% for the CdxSn(1−x)S (x = 0.50) hybrid materials than that of the pristine device (2.79%). The optimization of photovoltaic performance can be realized by x adjustments for the precursor solution. This study provides some references for the application and production of PSCs.
