  • INTEGRATED THIN-FILM SOLAR CELL AND METHOD OF MANUFACTURING THE SAME
    Publication number: 20100018574
    Abstract: Provided are an integrated thin-film solar cell and a method of manufacturing the same. The method comprises forming and patterning a conductive material to be adjacently spaced a predetermined distance apart from each other on a substrate; forming a solar cell (semiconductor) layer on the resultant substrate; obliquely depositing a first transparent conductive material on the solar cell layer; etching the solar cell layer using the first transparent conductive material as a mask; and obliquely depositing a second transparent conductive material on the resultant substrate, and electrically connecting the conductive material with the first transparent conductive material.
    Type: Application
    Filed: September 28, 2009
    Publication date: January 28, 2010
