Jalpaite Ag3CuS2: a novel promising ternary sulfide absorber material for solar cells

We report a novel promising semiconductor of Ag3CuS2 serving as absorber material in inorganic-organic solid-state solar cells for the first time, and the device (ITO/ZnO/Ag3CuS2/P3HT/Pt) exhibits a power conversion efficiency of 2.01%. This study opens up an available method to develop various ternary absorber materials for tertiary generation solar cells.
