中文摘要
本研究利用SCAPS-1D对采用双层吸光结构的全无机、叠层结构启发的钙钛矿太阳能电池（PSC）进行了详细的仿真分析。研究评估了器件结构FTO/TiO2/CsPbI3/CsSnI3在有无空穴传输层（HTL）情况下的性能，并采用了金（Au）、银（Ag）、碳和CZTS等多种背电极材料。其中，CsPbI3（宽带隙）作为顶层吸光层，CsSnI3（窄带隙）作为底层吸光层，能够在宽光谱范围内实现高效的光吸收。在无需空穴传输层的结构中，实现了高达33.75%的功率转换效率（PCE）。此外，使用成本低廉且可持续的CZTS替代传统金属电极仍能保持优异的器件性能。结果表明，在不使用有机空穴传输层的情况下，依然可以实现高效的能带排列与载流子传输，从而在维持高效率的同时简化了器件结构。本工作突出了全无机、叠层结构启发的钙钛矿器件架构在可扩展、高效且环境友好型光伏技术中的应用潜力。
English Abstract
Abstract This investigation delivers a detailed SCAPS-1D simulation of all-inorganic, tandem-inspired perovskite solar cells (PSC) utilizing a two-layer absorber configuration. The device configuration FTO/TiO 2 /CsPbI 3 /CsSnI 3 was evaluated in the presence and absence of a hole transport layer (HTL), using various back contact materials such as gold (Au), silver (Ag), carbon, and CZTS. CsPbI 3 (wide bandgap) functions as the top absorber, while CsSnI 3 (narrow bandgap) serves as the bottom absorber, allowing strong light harvesting over a wide spectral range. A high-power conversion efficiency (PCE) of 33.75% was attained in the HTL-free configuration. Additionally, replacing conventional metal electrodes with cost-effective, sustainable CZTS maintained excellent device performance. These results demonstrate that efficient energy band alignment and charge transport are achievable without organic HTLs, simplifying the device structure while maintaining high efficiency. This work underscores the potential of all-inorganic, tandem-inspired perovskite architectures for scalable, efficient, and eco-friendly photovoltaic technologies.
