MACl enhanced electron extraction in all-inorganic Cs2AgBiBr6 perovskite photovoltaics

Chem Commun (Camb). 2023 Jan 26;59(9):1173-1176. doi: 10.1039/d2cc06432d.

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.
