Efficient CuInSe[sub 2] Solar Cells Fabricated by a Novel Ink Coating Approach

Abstract
A novel technique is developed for the deposition of (CIS) thin films for solar cell applications. The technique uses an ink formulation that contains metallic pigments. A precursor layer is first formed coating this ink onto the selected substrate. The precursor film is then reacted with to form the CIS compound. Solar cells were fabricated on CIS absorber layers prepared by this low cost ink coating approach and devices with a conversion efficiency of over 9.0% were demonstrated. ©1998 The Electrochemical Society
