NOVELTY - The solar cell is formed by sealing a cell (4) between surface-side transparent protection component (1) and back surface side protection component (2). The surface-side sealing film (3A) containing ethylene and vinyl-acetate copolymer is positioned between surface-side transparent protection component and cell. The back surface-side sealing film (3B) containing ethylene, vinyl-acetate copolymer and white inorganic pigment, is positioned between back surface side transparent protection component and cell. The whiteness of film is 87-93% based on JIS-P-8148.    USE - Solar cell for electric power generation.    ADVANTAGE - The solar cell has excellent external appearance, effective irregular reflection in interface and improved electric power generation efficiency.    DETAILED DESCRIPTION - The solar cell is formed by sealing the cell through sealing films between the surface-side transparent protection component and a back surface side protection component. The surface-side sealing film is positioned between a surface-side transparent protection component and the cells. The surface-side sealing film is obtained by curing the composition containing ethylene and vinyl-acetate copolymer. The back surface-side sealing film which is a white film is positioned between back surface side transparent protection component and the cells. The back surface-side sealing film is obtained by curing the composition containing ethylene, vinyl-acetate copolymer and white inorganic pigment. The whiteness of the film is 87-93% based on B-system of JIS-P-8148. The white inorganic pigment is chosen from titanium oxide, calcium carbonate and aluminum oxide. The back surface side sealing film composition further contains crosslinking agent and crosslinking adjuvant. INDEPENDENT CLAIMS are included for the following:    (1) sealing film; and    (2) selection method of solar cell.
