Method of producing thin-film solar cell

Amended) A method of producing a thin-film solar cell including a semiconductor thin film that converts incident light into electricity, comprising:

• forming, on a heat resistant substrate, a flaky graphite layer having a thickness and a breaking stress in a thickness direction that is smaller than the breaking stress in a direction perpendicular to the thickness direction;
• forming a semiconductor thin film on said flaky graphite layer by means of a high temperature process;
• adhering a second substrate for supporting said semiconductor thin film to the side of said semiconductor thin film facing away from said flaky graphite layer;
• breaking said flaky graphite layer by applying a mechanical stress to said heat resistant substrate and said second substrate so that a stress acts along the thickness direction, whereby said semiconductor thin film is separated from said heat resistant substrate;
• and
• producing a rear electrode on said semiconductor thin film without removing fragments of said flaky graphite layer remaining on said semiconductor thin film, said fragments being used as part of said rear electrode.
