由于其高的光伏性能和低成本的溶液可加工性的制造方法，过氧化物太阳能电池（PVSC）引起了越来越多的关注。已经开发了多种方法来制备均匀致密的钙钛矿薄膜，这对器件性能起着关键作用。在本文中，我们展示了一种聚合物添加剂辅助的方法与聚酰胺胺（PAMAM）树枝状聚合物，以促进均匀，致密和超光滑的钙钛矿薄膜的生长。此外，已经开发了灯退火方法，以使用白炽灯快速退火钙钛矿膜，从而与对照热板退火相比，产生相当或甚至更好的器件性能。简单的聚合物添加剂辅助方法和快速灯退火技术为大规模制备高效PVSC提供了线索。
Perovskite solar cells (PVSC) have drawn increasing attention due to their high photovoltaic performance and low-cost fabrication with solution processability. A variety of methods have been developed to make uniform and dense perovskite thin films, which play a critical role on device performance. Herein, we demonstrate a polymer additive assisted approach with Polyamidoamine (PAMAM) dendrimers to facilitate the growth of uniform, dense, and ultra-smooth perovskite thin films. Furthermore, a lamp annealing approach has been developed to rapidly anneal perovskite films using an incandescent lamp, resulting in comparable or even better device performance compared to the control hotplate annealing. The facile polymer additive assisted method and the rapid lamp annealing technique offer a clue for the large-scale fabrication of efficient PVSCs.
