Abstract
Single-crystal perovskite solar cells with a lateral structure yield an efficiency enhancement 44-fold that of polycrystalline thin films, due to the much longer carrier diffusion length. A piezoelectric effect observed in perovskite single-crystal and the strain-generated grain-boundaries enable ion migration to form a p-i-n structure.
摘要
具有横向结构的单晶钙钛矿太阳能电池由于载流子扩散长度长得多，其效率提高了 44 倍，比多晶薄膜还要高。在钙钛矿单晶中观察到的压电效应以及应变产生的晶界使离子迁移，从而形成 p-i-n 结构。
