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.
