A composite liquid deposition approach merging the concepts of solution and particle‐based coating for multinary chalcogenide materials is demonstrated. Photovoltaic absorbers based on earth‐abundant Cu–Zn–Sn–S–Se kesterites show exceptional phase purity and are incorporated into solar cells with power conversion efficiency above 9.6%, bringing the state of the art of kesterite photovoltaic materials to a level suitable for possible commercialization.
