摘要

本研究提供了一个详细的SCAPS-1D模拟全无机，串联启发钙钛矿太阳能电池（PSC）利用两层吸收结构。采用金（Au）、银（Ag）、碳和CZTS等各种背触点材料，在有无空穴传输层（HTL）的情况下，对器件结构FTO/TiO2/CsPbI3/CsSnI3进行了评估。CsPbI3（宽带隙）作为顶部吸收剂，而CsSnI3（窄带隙）作为底部吸收剂，允许在宽光谱范围内收集强光。在无html配置中获得了33.75%的高功率转换效率（PCE）。此外，用具有成本效益、可持续发展的CZTS取代传统金属电极保持了优异的器件性能。这些结果表明，在没有有机HTLs的情况下，可以实现高效的能带对准和电荷输运，在保持高效率的同时简化了器件结构。这项工作强调了全无机、串联启发的钙钛矿架构在可扩展、高效和环保光伏技术方面的潜力。

Modeling of efficient dual-junction all-inorganic perovskite tandem cells via SCAPS-1D

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/TiO₂/CsPbI₃/CsSnI₃ 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. CsPbI₃ (wide bandgap) functions as the top absorber, while CsSnI₃ (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.
