具有横向结构的单晶钙钛矿太阳能电池由于更长的载流子扩散长度而产生比多晶薄膜高44倍的效率增强。在钙钛矿单晶中观察到的压电效应和应变产生的晶界使离子迁移形成钉扎结构。
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 pin structure.
