Abstract

A thin film solar cell is discussed. The thin film solar cell includes a substrate, a front electrode positioned on the substrate, a back electrode positioned on the front electrode, and a photoelectric conversion unit positioned between the front electrode and the back electrode. The front electrode includes first and second front electrode layers each containing a conductive material with light transmissivity. The first front electrode layer is formed on the substrate and contacts the substrate, and a porous pin hole exposing a portion of the substrate is formed in a portion of the first front electrode layer. The second front electrode layer contacts the first front electrode layer and covers the porous pin hole of the first front electrode layer.
