US 2013/0152995 A1 · SOLAR CELL MODULE AND METHOD FOR PRODUCING THE SAME

Abstract

A solar cell module which not only can ensure that rays of light in a satisfactory amount enter the solar cells but also can suppress the deterioration of the antireflection film in reflectance to surely achieve excellent durability. By forming, on the surface of a first antireflection film, a second antireflection film having a void ratio smaller than that of the first antireflection film, CO2 and H2O in air are prevented from permeating through the antireflection film, so that a reaction of CO2 and H2O with alkali ions on the surface of a light-transmitting member is unlikely to proceed, making it possible to cause rays of light in a satisfactory amount to surely enter the solar cells and to suppress the deterioration of the antireflection film in reflectance to surely achieve excellent durability.
