PROBLEM TO BE SOLVED: To provide a black rear surface protective sheet for a solar battery, suppressed in absorption of light in a near infrared region and an infrared region of the sunlight.SOLUTION: A rear surface protective sheet for a solar battery is disposed on the rear surface side of a solar battery cell. (1) The rear surface protective sheet for a solar battery comprises one layer or two layers or more of laminates, and at least one layer of the laminates contains a composite metal oxide including two or more metals selected from the group consisting of Fe, Cu, Ni, Cr, Bi, Mn, Sr, Y and Al, and (2) the rear surface protective sheet for a solar battery is black with an average reflectance in a wavelength region from 400 to 750 nm of 10% or less, and has an average reflectance in a wavelength region from 750 to 2,000 nm of 50% or more. |
