NOVELTY - Manufacturing regenerated photovoltaic cell (1) or transparent front face substrate (5), which is obtained from photovoltaic module (10) comprising an encapsulant layer (4a) for photovoltaic module, placed on at least one surface of photovoltaic cell, comprises: (a) heating the photovoltaic module at temperatures not lower than softening temperature of a thermoplastic resin which is a constituent material of the separable layer; (b) peeling the separable layer, plasticized by heating, to separate the photovoltaic cell; and (c) removing the encapsulant layer adhered to the photovoltaic cell.    USE - The method is useful for: manufacturing regenerated photovoltaic cell or regenerated transparent front face substrate; and reutilizing a photovoltaic module (all claimed).    ADVANTAGE - The method: provides photovoltaic module, which utilizes encapsulant layer enabling recovering and recycling or reusing of reutilizeable resources e.g. transparent front face substrate and photovoltaic cell, thus the process is economical and suitable for global environments; provides photovoltaic cell having a total ray transmittance of 70-100% allowing power generation efficiency; and provides transparent front face substrate having transmittance of solar light, electric insulation property and is excellent in mechanical, chemical or physical strength and also protects the module from wind, weather, outer impact, fire and securing reliability for a long period of time.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for reutilizing a photovoltaic module, where a component from a photovoltaic module comprising an encapsulant layer for photovoltaic module, placed on at least one surface of a photovoltaic cell is reutilized, comprising: (a) as above per see; and (b1) peeling the separable layer plasticized by heating to separate the transparent front face substrate.    DESCRIPTION OF DRAWING(S) - The figure shows a schematic sectional view of the photovoltaic module.
