NOVELTY - Several transparent conductive films (A) (2) and a transparent conductive film (B) are sequentially formed on a transparent insulation substrate (1). The transparent conductive film is etched on the granular form, and the formed granules (A) are scattered on the film (A). An electric power generation layer (5) is formed on the transparent conductive film (A) and scattered granules (A). A back surface electrode layer (6) is formed on the electric power generation layer by performing back surface electrode stratification process, to manufacture thin film solar cell (10).    USE - Manufacture of thin film solar cell (claimed).    ADVANTAGE - The thin film solar cell has excellent reliability and photoelectric transfer characteristics, and provides favorable optical confinement effect and uniform resistance. The defects in electric power generation layer are reduced, and thus short circuits and leakage in thin film solar cell are prevented.    DETAILED DESCRIPTION - Several transparent conductive film (A) mutually separated within in the surface of substrate is formed on a transparent insulation substrate, and a transparent conductive film (B) is formed on the transparent conductive film (A). The transparent conductive film is etched on the granular form, and the formed granules (A) are scattered on the transparent conductive film (A). An electric power generation layer is formed on the transparent conductive film (A) and scattered granules (A) by performing electric power generation stratification process. A back surface electrode layer is formed on the electric power generation layer by performing back surface electrode stratification process, to manufacture thin film solar cell. An INDEPENDENT CLAIM is included for thin film solar cell.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic sectional view of thin film solar cell.
