SOLAR CELL INCLUDING MULTIPLE BUFFER LAYER FORMED BY ATOMIC LAYER DEPOSITION AND METHOD OF FABRICATING THE SAME

摘要

Provided are a solar cell and a method for fabricating the same. The solar cell includes: a substrate; a back electrode layer formed on the substrate; a light absorbing layer formed on the back electrode layer; a buffer layer including an O-free first buffer layer formed on the light absorbing layer by atomic layer deposition (ALD) and a second buffer layer formed on the first buffer layer by the atomic layer deposition (ALD); and a front electrode layer formed on the buffer layer.
