Abstract
A solar cell module reverse face protection sheet reduces absorption of sunlight to depress temperature rise in a solar cell module and serves for efficient use of reflected light for power generation, thereby ensuring a high power generation efficiency and maintaining a high partial discharge voltage. The solar cell module reverse face protection sheet includes a white polyolefin film and a hydrolysis resistant polyester film, wherein the absorptance is 10% or less for light in the wavelength range of 400 to 2,200 nm coming through the white polyolefin film while the reflectance for light in the above wavelength range is 70% or more.
