摘要

我们通过改进的顺序两步沉积技术构建了具有自下而上n-p同质结的高质量钙钛矿薄膜，优化了钙钛矿层与相邻触点之间的能级排列，促进了电荷的分离和提取，并抑制了非辐射复合。所得到的基于n-p同质结的电子输运无层钙钛矿太阳能电池的效率得到了提高，比对照电池高出约13%。

Constructing bottom-up n-p perovskite homojunctions for enhanced performance of electron transport layer-free solar cells

We constructed the high-quality perovskite films with bottom-up n-p homojunctions via a modified sequential two-step depostion technique, which optimized the energy level alignment between the perovskite layer and the adjacent contacts for promoting the charge separation and extraction, as well as suppressing the non-radiative recombination. The resultant n-p homojunction-based electron transport layer-free perovskite solar cells achieved improved efficiency, which was ~13 % higher than that of the control counterpart.
