We have fabricated 15.4[percent] and 12.4[percent] efficient thin-film CuIn[sub 1[minus]x]Ga[sub x]Se[sub 2] (CIGS)-based photovoltaic devices from solution-based electrodeposited (ED) and electroless-deposited (EL) precursors. As-deposited precursors are Cu-rich CIGS. Additional In, Ga, and Se are added to the ED and EL precursor films by physical vapor deposition (PVD) to adjust the final semiconductor film composition to CuIn[sub 1[minus]x]Ga[sub x]Se[sub 2]. The ED and EL device parameters are compared with those of a 17.7[percent] PVD device. The tools used for comparison are current voltage, capacitance voltage, and spectral response characteristics.
