摘要：

In this paper, the self-made setup with excellent controllability and general applicability was developed for the preparation of perovskite thin films using vapor-assisted solution process. The CH3NH3I treatment temperature was 130 degrees C, 140 degrees C, 150 degrees C in vapor-assisted solution process, the grain size of the corresponding perovskite thin films was similar to 600 nm, similar to 400 nm, similar to 200 nm, and the best photoelectric conversion efficiency of the corresponding perovskite solar cells was 12.62%, 11.72% and 11.50%, respectively. The result demonstrated that the CH3NH3I treatment temperature can be decreased from 150 degrees C to 130 degrees C and the large grain and full-coverage perovskite thin film was obtained using the self-made setup at the CH3NH3I treatment temperature of 130 degrees C in ambient atmosphere because the CH3NH3I treatment temperature was usually 150 degrees C.
