Behind the Breakthrough of the ～30% Perovskite Solar Cell

摘要

In the December 11, 2020 issue ofScience, Al-Ashouri and colleagues reported a certified monolithic perovskite/silicon tandem solar cell with the power conversion efficiency 29.15%. The improvements of the ideality factor and the fill factor are key to achieving efficient perovskite tandem solar cells, which lead a new direction of the perovskite research.
