Abstract
A solar cell device and a method of fabricating the device is described. The solar cell is fabricated by forming a back contact layer on a front side of a substrate, forming an absorber layer on the back contact layer, applying a protective layer on a back side of the substrate, depositing a buffer layer on the absorber layer. Excess buffer materials are deposited on the substrate back side, and the protective layer with excess buffer materials are removed.
