Research progress in large-area perovskite solar cells

The record power conversion efficiency of small-area perovskite solar cells has impressively exceeded 25%. For commercial application, a large-area device is the necessary next step. Recently, significant progress has been achieved in fabricating efficient large-area perovskite solar cells. In this review, we will summarize recent achievements in large-area perovskite solar cells including the deposition methods as well as growth control of the large-area, high-quality perovskite layer and also the charge transport layer. Finally, we will give our insight into large-area perovskite solar cells.
