Title:
BACKSIDE PROTECTIVE SHEET FOR SOLAR CELL MODULE
Document Type and Number:
WIPO Patent Application WO/2011/145599
Kind Code:
A1
Abstract:
Disclosed is a backside protective sheet for a solar cell module, which suppresses increase in the temperature of a solar cell module by reducing absorption of sunlight, while enabling high power generation efficiency through efficient use of the reflected light in power generation. In addition, the backside protective sheet for a solar cell module is capable of maintaining high partial discharge voltage.
Specifically disclosed is a backside protective sheet for a solar cell module, which is composed of a white polyolefin film and a hydrolysis-resistant polyester film. The backside protective sheet for a solar cell module is characterized in that the absorptance of light having a wavelength of 400-2,200 nm from the white polyolefin film side is 10% or less and the reflectance of light having the above-mentioned wavelength is 70% or more.
