摘要: 为了制备高性能的钙钛矿太阳能电池,甘氨酸盐酸盐(Gly+)被用来钝化薄膜缺陷。Gly+作为添加剂被引入钙钛矿前驱体溶液。Gly+和钙钛矿之间存在分子间相互作用,可以有效地控制结晶过程。引入Gly+之后,钙钛矿薄膜的晶粒尺寸变大,结晶度提高。稳态荧光(PL)以及暗电流测试表明添加剂减少了器件的非辐射复合。与原始器件(2013%)相比,添加剂的加入大大提升了器件效率,其最高值为2235%;同时,器件的空气稳定性和热稳定性都得到改善。

Abstract: In order to prepare high-performance perovskite solar cells, glycine hydrochloride (Gly+) was used to passivate thin films defects. The additive of Gly+ was introduced into the perovskite precursor solution. The intermolecular interaction between Gly+ and perovskite can effectively control the crystallization dynamic. Gly+ enlarges the grain size of perovskite films and improves the crystallinity. Dark current and steady-state luminescence (PL) measurements indicate that the additive reduces the nonradiative recombination of the device. Compared with the control device of 2013%, the device based on perovskite film with Gly+ improves the efficiency up to 2235%. Additionally, Gly+-based devices show improved air stability and thermal stability.
