NOVELTY - Silicone cured film is formed on each single side of hard surface panel (1) and back surface sheet (2) and arranged such that photovoltaic cell string is inserted between silicone cured film surface of surface panel and back surface sheet, to form laminate. The laminate is pressed, heated and the photovoltaic cell string is sealed, to obtain silicone-sealed solar cell module. The silicone cured film comprises cured film (X) of organopolysiloxane composition (I) containing organopolysiloxane (A-1) and organic compound (A-2), and cured film (Y) of organopolysiloxane composition (II).    USE - Manufacture of silicone-sealed solar cell module (claimed).    ADVANTAGE - The method provides solar cell module having excellent adhesion reliability without producing gap while sealing photovoltaic cell string.    DETAILED DESCRIPTION - Silicone cured film is formed on each single side of hard surface panel and back surface sheet having flexibility, and arranged such that photovoltaic cell string is inserted between silicone cured film surface of surface panel and back surface sheet, to form laminate. The laminate is pressed, heated in reduced pressure space, and the photovoltaic cell string is sealed, to obtain silicone-sealed solar cell module. The silicone cured film comprises cured film (X) of organopolysiloxane composition (I) containing 80-100 parts mass organopolysiloxane (A-1) having viscosity of 100-100000 mPa.second at 23 degrees C and contains aliphatic unsaturated group(s) bonded with silicon atom in 1 molecule and 0-20 parts mass organic compound (A-2) containing aliphatic unsaturated group(s) which is capable of undergoing hydrosilylation reaction with respect to hydrogen atom, bonded with silicon atom in 1 molecule, such that total content of organopolysiloxane (A-1) and organic compound (A-2) is 100 parts mass, organo-hydrogen-polysiloxane containing two or more hydrogen atoms bonded with silicon atom in 1 molecule, and effective dose of hydrosilylation reaction catalyst chosen from platinum group metal-type catalyst, and cured film (Y) of organopolysiloxane composition (II) containing 80-100 parts mass organopolysiloxane (D-1) having viscosity of 100-100000 mPa.second at 23 degrees C and containing aliphatic unsaturated group(s) bonded with silicon atom in 1 molecule and 0-20 parts mass organic compound (D-2) containing aliphatic unsaturated group(s) which is capable of undergoing hydrosilylation reaction with respect to hydrogen atom, bonded with silicon atom in 1 molecule, such that total content of components (D-1) and (D-2) is 100 parts mass, organo-hydrogen-polysiloxane containing 2 or more hydrogen atom(s) bonded with silicon atom in 1 molecule, and effective dose of hydrosilylation reaction catalyst chosen from platinum group metal-type catalyst. The ratio (p) of number-of-moles (b) of hydrogen atom bonded with the silicon atom contained in component (A-1) with respect to total number-of-moles (a) of aliphatic unsaturated group in component (A-2) is 0.25 to less than 1.3. The ratio (q) of number-of-moles (e) of hydrogen atom bonded with the silicon atom contained in component (D-1) with respect to total number-of-moles (d) of aliphatic unsaturated group in component (D-2) is more than 0.3 to 10. The molar ratio of number-of-moles ratios (q) and (p) is 1.3 or more. The modulus of product of number-of-moles ratios (q) and (p) is more than 0.7.
