Most common thin-film solar panels consist of expensive rare-earth elements like indium and gallium, or highly toxic metals like cadmium. Environment-friendly solar panels consisting of the abundant materials Cu, Zn, Sn offer attractive alternatives, but are hindered by their low practical efficiency compared to their theoretical potential. Researchers from DGIST have now discovered a way to overcome these hurdles.
