NOVELTY - A solar cell (1) consists of an aluminum material (11) integrated to the surface(s) of a base material (13). An upper electrode (50) and a lower electrode (20) on the upper and lower sides of a photoelectric conversion layer (30) are provided on the metal substrate (10) with an insulating layer. The photoelectric conversion layer is formed using group-Ib-element-containing particles containing copper and/or silver, and group-IIIb-element-containing particles containing aluminum, indium and/or gallium.    USE - Solar cell e.g. copper-indium-gallium diselenide solar cell and copper-indium diselenide type solar cells.    ADVANTAGE - The solar cell has excellent photoelectric conversion efficiency. Peeling of photoelectric conversion layer during cooling after heating at high temperature in the manufacture of solar cell, is prevented. Crack of anodized film by thermal distortion is prevented. The metal substrate has excellent heat resistance and rigidity. Influence on other layer by shrinkage or deformation of substrate is prevented.    DETAILED DESCRIPTION - A solar cell consists of an aluminum material integrated to the surface(s) of a base material consisting of ferritic stainless steel as metal substrate (14). An upper electrode and a lower electrode arranged on the upper and lower sides of a photoelectric conversion layer are provided on the metal substrate with an insulating layer provided by forming an anodized film (12) of aluminum on the surface of aluminum material as electric insulation layer. The photoelectric conversion layer is formed using group-Ib-element-containing particles containing copper and/or silver, and group-IIIb-element-containing particles containing aluminum, indium and/or gallium. An INDEPENDENT CLAIM is included for manufacture of solar cell.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic cross-sectional view of the solar cell in the transversal direction.
