THIN FILM SOLAR CELL AND METHOD OF FORMING SAME

摘要

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.

1. A method for fabricating a solar cell, comprising:
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 said substrate; depositing a buffer layer on said absorber layer, wherein excess buffer materials are deposited on said substrate back side during said depositing; and removing said protective layer and said excess buffer materials thereon.
