Abstract

A novel precursor suitable to prepare uniform CuInGaSe2 thin films on an 1 inch2 area has been developed. The precursor is obtained by depositing in sequence In2Se3, Cu and Ga on a Mo covered glass and by a subsequent annealing at 400°C in vacuum for 1-2 hours. By selenizing this precursor in a Se-flux in vacuum for half an hour at 500°C substrate temperature a uniform and well crystallized CuInGaSe2 film is obtained. Solar cells prepared by depositing in sequence on top of the CuInGaSe2 film 60 nm of CdS, 100 nm of pure ZnO and 2 μm of ZnO:Al exhibit a uniform efficiency of 14,5% over the 1 inch2 area.
