Abstract

Perovskite hybrid solar cells (pero-HSCs) have attracted significant attention due to their promising photovoltaic efficiency, solution processibility, and low-cost manufacturing process. In this study, we report efficient solution-processed planar heterojunction (PHJ) pero-HSCs. By fine-tuning the film formation procedures, uniform perovskite thin films with high surface coverage and superior optical and electrical properties are produced, which results in over 14% efficiency. These results demonstrate that the quality of perovskite thin films plays an important role in approaching efficient solution-processed PHJ pero-HSCs.
