Abstract:
1. An article comprising one or more polymeric precursor compounds for CAIGS, CAIS, or CAGS deposited onto a substrate; thereby forming a thin film of the polymeric precursor compounds; wherein the polymeric precursor compounds have the empirical formula (Cu 1−x Ag x ) u (M B1 1−y M B2 y ) v ((S 1−z Se z )R) w , wherein M B1 and M B2 are different atoms of Group 13, x is from 0.001 to 0.999, y is from 0 to 1, z is from 0 to 1, u is from 0.5 to 1.5, v is from 0.5 to 1.5, w is from 2 to 6, and R represents R groups, of which there are w in number, which are each independently selected from alkyl, aryl, heteroaryl, alkenyl, amido, silyl, and inorganic and organic ligands.
