Abstract

A humidity resistant and versatile fabrication method for the production of very high quality, organic-inorganic perovskite films, solar cells and solar modules is presented. By using ethyl acetate as an anti-solvent during deposition, perovskite solar cells with power conversion efficiencies (PCEs)...
