<p><P>PROBLEM TO BE SOLVED: To provide a sheet for a solar-cell module rear sealing having superior adhesive properties with EVA and having steam barrier and weatherability. <P>SOLUTION: In the sheet for rear sealing, an inorganic oxide layer and an adhesion-improved layer are formed, on at least a transparent base material film, a laminate laminating a white film and a weatherable film on the inorganic-oxide layer is used and total-beam transmittance of the film forming both the inorganic oxide layer and the adhesion-improved layer on the transparent base material film is 85% or higher. In the sheet for rear sealing, starting from the adhesion-improved layer, transparent base material film, inorganic oxide layer, adhesive layer, white film, adhesive layer and weatherable film are laminated, in this order starting from the side contacting the filler layer in, for the order of the overall laminated constitution, and the mean reflectance of wavelengths 410 to 800 nm, measured from the adhesion-improved layer side in a laminated state, is 85% or higher. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
