<P>PROBLEM TO BE SOLVED: To provide a rear surface protective sheet for a solar cell module which is improved in strength, weather resistance, heat resistance, waterproofing properties and moisture-resistant properties, and excellent in a property of adhesion with a filling layer when temporal durability is required, and is not released from the filling layer. <P>SOLUTION: A solar cell module comprises a filling layer for fixing a solar cell with at least a filling material, a front surface protective sheet layered on the filling layer at a sunlight-incident side and a rear surface protective sheet layered on an opposite side. In the solar cell module, the rear surface protective sheet comprises a weather-resistant layer 22 which has hydrolysis resistance and whose relative thermal index is 100°C or higher; an insulating layer 21 for preventing discharging from the solar cell to the outside; and an insulated/easy-adhesion resin layer 23 which has an insulation property and to which a coloring agent capable of strong adhesion to the filling layer is added. <P>COPYRIGHT: (C)2011,JPO&INPIT |
