Title:
太陽電池モジュール用の裏面保護シート
Document Type and Number:
Japanese Patent JP7234564
Kind Code:
B2
Abstract:
To maintain the original design that should be exhibited by a dark color layer while significantly suppressing the reduction in power generation efficiency in a back surface protective sheet for a solar cell module that includes a structure in which the dark color layer and a transparent adhesion layer are laminated.SOLUTION: In a back surface protective sheet 1 for a solar cell in which a reflective layer 11, an infrared-transparent dark color layer 12, and a transparent adhesive layer 13 are laminated, in the transparent adhesive layer 13, a polyethylene resin having a density of 0.910 g/cmor more and 0.960 g/cmor less is used as a base resin, and average diffuse reflectance in which the thickness is 25 nm or more and 65 nm or less, and the wavelength of the outermost surface where the transparent adhesive layer 13 is exposed is 400 nm or more and 750 nm or less is 4% or more and 8% or less.SELECTED DRAWING: Figure 1
