Hole transport material (HTM) is a major component of perovskite solar cells (PSCs). PEDOT: PSS, an organic HTM, is widely used in inverted (p-i-n) PSCs. While PEDOT: PSS is unstable, expensive and it's acidic nature could deteriorate the absorber. Copper zinc tin sulphide (CZTS), an inorganic semiconductor can be used as HTM due to its properties such as low cost, ease of synthesis and high hole mobility. In this work, device simulation of inverted (p-i-n) PSC was performed with CZTS as HTM to exploit its maximum capability. Remarkable power conversion efficiency (PCE) of 25.43% was achieved after optimizing the performance. Device performance was strongly affected by thickness and electron affinity of HTM as well as diffusion length of carriers. PCE of real fabricated device was also found to be 9.72%. This work demonstrates CZTS is a promising candidate to replace PEDOT: PSS from both experimental and theoretical perspectives.

空穴传输材料 (HTM) 是钙钛矿太阳能电池 (PSC) 的主要组成部分。PEDOT：PSS 是一种有机 HTM，广泛用于倒置（销）PSC。而 PEDOT：PSS 不稳定、价格昂贵，而且它的酸性性质可能会使吸收剂劣化。铜锌硫化锡 (CZTS) 是一种无机半导体，由于其低成本、易于合成和高空穴迁移率等特性，可用作 HTM。在这项工作中，使用 CZTS 作为 HTM 执行倒置（引脚）PSC 的器件模拟，以利用其最大能力。优化性能后实现了 25.43% 的显着功率转换效率 (PCE)。器件性能受 HTM 的厚度和电子亲和力以及载流子扩散长度的强烈影响。还发现实际制造的设备的 PCE 为 9.72%。
