In this paper, we fabricated a TiO homogeneous hybrid structure for application in perovskite solar cells (PSCs) under ambient conditions. Under the standard air mass 1.5 global (AM 1.5G) illumination, PSCs based on homogeneous hybrid structure present a maximum power conversion efficiency of 5.39% which is higher than that of pure TiO nanosheets. The enhanced properties can be explained by the better contact of TiO nanosheets/nanoparticles with CHNHPbI and fewer pinholes in electron transport materials. The advent of such unique structure opens up new avenues for the future development of high-efficiency photovoltaic cells.

在本文中，我们在环境条件下制备了一种用于钙钛矿太阳能电池（PSC）的TiO均匀混合结构。在标准空气质量1.5全球（AM 1.5G）光照下，基于均匀混合结构的PSC呈现出5.39%的最大功率转换效率，高于纯TiO纳米片的效率。TiO纳米片/纳米颗粒与CHNHPbI的更好接触以及电子传输材料中较少的针孔可以解释这种增强的性能。这种独特结构的出现为高效光伏电池的未来发展开辟了新途径。
