Abstract

We present organic-halide treatment in advance to maximize electron extraction of Cs₂AgBiBr₆ double perovskite solar cells. Through optimizing the organic halide and concentration systematically, the best carbon-based Cs₂AgBiBr₆ perovskite solar cell fabricated in an airing chamber achieves a power conversion efficiency of 2.03% and shows excellent long-term stability in air over 30 days.
