SOLAR CELL AND METHOD OF MANUFACTURING THE SAME

摘要

A solar cell includes a substrate, a barrier layer on the substrate, a back electrode layer on the barrier layer, a light absorption layer on the back electrode layer, a buffer layer on the light absorption layer, and a transparent electrode layer on the buffer layer. The barrier layer is selectively formed on the substrate. Accordingly, since alkali elements may be uniformly distributed in the light absorption layer, the efficiency of the solar cell may be improved.
