研究目的
To analyze and optimize the performance of perovskite solar cells (PSCs) using Cu2ZnSnS4 (CZTS) as an inorganic hole transporting material (HTM) through numerical modeling.
研究成果
The optimized PSC structure with CZTS as HTM significantly improves the PCE from 12.76% to 22.70% by optimizing parameters like absorber layer thickness, defect density, and doping densities of ETM and HTM. The study demonstrates the potential of CZTS as an efficient and stable HTM for PSCs.
研究不足
The study is based on numerical simulation, which may not fully capture all real-world conditions and material behaviors. The performance improvements are theoretical and need experimental validation.
