Manufacturing methods of patterned stress relaxation layer and reflecting layer by block copolymer template deposited on flexible substrate and solar cell using the same

摘要

The present invention relates to a manufacturing method of a stress relieving layer of a flexible substrate, a method of manufacturing a total reflection film of a back electrode, and a thin film solar cell including the same, and more particularly, to a thin film solar cell comprising nano- And the optical path length is further extended to significantly improve the overall photovoltaic efficiency.
