Progress toward Applications of Perovskite Solar Cells

This is the authors' abstract. We don't add key points for this paper.

With the deepening of study on perovskite solar cells (PSCs) all over the world, the power conversion efficiency (PCE) has rapidly increased from 3.8% to 25% in recent years, and the perovskite material is expected to become an ideal absorption material for solar cells at low cost in the future. However, some problems are necessary to solve on the way toward practical applications of perovskite solar cells. This paper summarizes the recent research progress from the aspects of structural improvement for further PCE enhancement, material stability and life improvement, large-area preparation, replacement of toxic ingredients, and resolution of hysteresis in performance characterization. The progress in these field has been very fruitful, and will provide references for future research.
