The vapor-solid reaction method (VRM) is one of the promising techniques to prepare high-performance perovskite solar cells. Herein, PbI precursor films were prepared by vacuum evaporation. It was found that the PbI precursor films exhibit high crystallinity and orderly morphology at the substrate temperature of 110 °C. On this basis, the precursor films were prepared by VRM to obtain high-quality perovskite films and the power conversion efficiency (PCE) of perovskite solar cells (PSCs) devices reached 17.1%. In contrast, the PbI film precursor was prepared on the substrate without being heated and the PCE of the final PSCs devices was only 13.04%.
气固反应法（VRM）是制备高性能钙钛矿太阳能电池的一种很有前景的技术。在此，通过真空蒸发制备了PbI前驱体薄膜。发现在110°C的衬底温度下，PbI前驱体薄膜具有高结晶度和有序的形貌。在此基础上，通过气固反应法制备前驱体薄膜以获得高质量的钙钛矿薄膜，钙钛矿太阳能电池（PSC）器件的功率转换效率（PCE）达到了17.1%。相比之下，在未加热的衬底上制备PbI薄膜前驱体，最终PSC器件的PCE仅为13.04%。
