High-efficiency solar cell with earth-abundant liquid-processed absorber
Abstract
(Figure Presented) A composite liquid deposition approach merging the concepts of solution and particle-based coating for multinary chalcogenide materials is demonstrated. Photovoltaic absorbers based on earthabundant 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. © 2010 WILEY-VCH Verlag GmbH & Co.
