Recent Development of Lead-Free Perovskite Solar Cells

Abstract

Recently, the world energy demand has been raised up dramatically. Numerous energy sources have been developed to satisfy the urgent energy desires and to overcome the world energy crisis. Among them, solar energy has been considered an efficient energy source for current energy requirements. Nowadays, the lead-based perovskite solar cells achieved excellent power conversion efficiency exceeding 29.1%. However, to address major problems such as toxicity and underprivileged stability, several hardworks were made toward the replacement of lead-free perovskite material in perspective of device’s performance and stability. In this book chapter, we summarize material, dimensions, stability, and the current achievement of lead-free solar cells. Finally, we review the remaining challenges and future perspective for development of lead-free perovskite solar cells.
