Abstract:
1. A method for forming a thin film photovoltaic device comprising: forming a first layer above a substrate, wherein the first layer is operable as a back contact material of the thin film photovoltaic device; forming a second layer above the first layer, wherein the second layer is operable as an absorber material of the thin film photovoltaic device; forming a third layer above the second layer, wherein the third layer is operable as a buffer material of the thin film photovoltaic device; forming a fourth layer above the third layer, wherein the fourth layer is operable as an intrinsic zinc oxide material of the thin film photovoltaic device; forming a fifth layer above the fourth layer, wherein the fifth layer is operable as a transparent conductive oxide material of the thin film photovoltaic device, wherein the transparent conductive oxide material comprises a tin oxide material doped with antimony, and wherein the tin oxide material doped with antimony is deposited using a reactive sputtering process; and annealing the antimony doped tin oxide material.
