A model for the successful growth of polycrystalline films of CuInSe₂ by multisource physical vacuum evaporation

Abstract

Solar cells based on CuInSe 2 polycrystalline thin films (see Figure) are one of the few realistic alternatives to polycrystalline Si for practical conversion of solar energy into electricity. A model explaining the important role of the secondary copper chalcogenide phases in the deposition of the CuInSe 2 films by physical vacuum evaporation is presented. magnified image
