Abstract:
1. A method of manufacturing integrated thin film solar cells, comprising the steps of: (a) forming a transparent electrode pattern over a transparent substrate, the; (b) forming a solar cell layer over the substrate of the step (a); (c) forming a first back electrode by obliquely depositing a first conductive material over the solar cell layer, wherein the oblique deposition of the first conductive material results in one or more portions of the solar cell layer remaining exposed; (d) etching the exposed portion of the solar cell layer by using the first back electrode as a mask; and (e) forming a second back electrode so that the transparent electrode pattern and the first back electrode are electrically connected by obliquely depositing a second conductive material over the substrate of the step (d).
