The main object of the present invention is to provide an encapsulant layer for photovoltaic module used in a photovoltaic module enabling recovering and recycling or reusing of reutilizeable resources such as a transparent front face substrate and photovoltaic cell and the like among constituents of a photovoltaic module, and to provide a method for manufacturing a regenerated photovoltaic cell and a regenerated transparent front face substrate. The present invention attains the above mentioned object by providing an encapsulant layer for photovoltaic module, wherein the encapsulant layer for photovoltaic module is used in a photovoltaic module formed by laminating: a transparent front face substrate; a photovoltaic cell carrying a wiring electrode and a takeoff electrode, and an encapsulant layer is placed on at least one surface; and a rear face protecting sheet, in this order, comprising a separable layer formed mainly of a thermoplastic resin (a) having a peeling strength from the transparent front face substrate, measured in a 180° peeling test under a 25° C. atmosphere, in a range of 1 N/15 mm width to 150 N/15 mm width, (b) having a Vicat softening temperature, measured based on JIS standard K7206, in a range of 60° C. to 128° C., and (c) having a melt mass flow rate, measured based on JIS standard K7210, in a range of 0.1 g/10 min to 50 g/10 min, and wherein (d) an output maintenance factor of photoelectronic power, before and after a test measured based on a standard, of the photovoltaic module using the encapsulant layer is in a range of 80% to 100%. |
