摘要

提出一种免空穴传输层的策略,将自组装单分子层材料作为钙钛矿活性层的添加剂,通过一步旋涂法直接将钙钛矿薄膜制备在导电基底表面,其中薄膜的质量与均一性都得到改善。进一步地,将该方法应用在低成本的商用金刚线切片上,可在高粗糙度的硅表面制备出覆盖度高、形貌致密、无空洞的钙钛矿薄膜。在光电性能方面,用该方法得到的单结钙钛矿太阳电池的光电转换效率为21%,填充因子高达83%,两端钙钛矿/硅叠层太阳电池的光电转换效率为28%。

Abstract

In this study, a strategy of hole transport layer-free （HTL-free） is proposed. The self-assembled monolayer is used as the additive of perovskite active layer, then the perovskite film is directly deposited on the conductive substrate surface using a one-step spin coating method, and the quality and uniformity of the film are improved. Furthermore, the method is applied to the commercial and low-cost diamond-wire sawn with high surface roughness, resulting in the formation of a perovekite film characterized by high coverage,dense morphoogy, and absence of cavities. In terms of the photoelectric performance, the single-junction perovskite solar cells yield a champion power conversion efficiency （PCE） of 21.3%, with a high fill factor （FF） of over 83%. Finally, a PCE of 28% for perovskite/silicon tandem solar cells based on diamond-wire sawn is demonstrated.
