Gas Quenching for Perovskite Thin Film Deposition

Abstract

The rapid development of lead halide perovskites has already laid much of the groundwork for the eventual commercialization of corresponding opto-electronics, particularly solar cells. Nevertheless, several key challenges remain in the ‘lab-to-fab’ process, among which is the convenient fabrication of large-area high quality perovskite films. Herein, gas quenching (GQ) is highlighted as a deposition strategy that has been proven reproducible and composition-independent in a laboratory environment, and shows clear signs of vast potential for large-area fabrication.
