Solar cell

Abstract

A solar cell comprising a substrate of insulating material, a bottom side electrode layer formed on one surface of the substrate, a semiconductor photoelectric conversion layer formed on the bottom side electrode layer, a transparent top side electrode layer formed on the semiconductor photoelectric conversion layer and a non-transparent electrode comprising a plurality of strips of non-transparent conductive layers disposed separately from each other on the top side transparent electrode layer. The solar cell further comprises an additional bottom side electrode layer formed on the opposite surface of the substrate and a plurality of conductive paths connecting the bottom side electrode layer to the additional bottom side electrode layer through holes or slits formed to penetrate the substrate.
