Solution-processed sulfur depleted Cu(In, Ga)Se2 solar cells synthesized from a monoamine–dithiol solvent mixture

A monoamine–dithiol mixture is used to prepare homogeneous Cu(In, Ga)Se₂ (CIGSe) molecular precursor solution, which yields a highly sulfur depleted CIGSe thin-film solar cell with a power conversion efficiency of 12.2%.
