Double Layer Composite Electrode Strategy for Efficient Perovskite Solar Cells with Excellent Reverse-Bias Stability

Abstract

Highlights A composite electrode strategy to fabricate the perovskite solar cells (PSCs) with excellent comprehensive stabilities, particularly reverse-bias stability. A record efficiency of 23.7% (certified 23.2%) for n-i-p PSCs using Cu as the electrode. The strategy can be extended to the combinations of different transparent conducting oxides and low-cost metals.
