<P>PROBLEM TO BE SOLVED: To provide a resin sheet for formation of encapsulating films for solar battery modules that can restrain cell cracking likely to occur in solar battery module manufacturing when an encapsulating film is formed by thermally hardening resin in a state in which a crystalline silicon photovoltaic element is sandwiched between two resin sheets, and thereby to make possible more economical manufacturing of solar battery modules. <P>SOLUTION: A resin sheet for formation of encapsulating films for crystalline silicon solar battery modules, being in a sheet shape of 0.3 to 1.0 mm in thickness, is stacked over each of the front and rear sides of a thin planar-shaped crystalline silicon photovoltaic element, on which a thin planar-shaped linear leads are arranged, to form an encapsulating film for a crystalline silicon solar battery module. A linear concave whose depth is substantially equal to or greater than the lead thickness is disposed on the side of the embossed face in contact with the crystalline silicon photovoltaic element in a position in which the sheet is arranged overlapping the lead. <P>COPYRIGHT: (C)2013,JPO&INPIT |
