SOLAR BATTERY MODULE

摘要

PROBLEM TO BE SOLVED: To minimize the degradation of solar battery performance under long-term outdoor exposure, particularly under high-temperature, high-humidity environments, by composing the solar battery of an ethylene-unsaturated fatty acid ester-unsaturated fatty acid ternary copolymer. SOLUTION: Photovoltaic elements 301 are laminated using a sealing material together with an ETFE film as a front film 303, which is prepared by corona- discharging a surface for bonding to a lower-layer closing material, a polyethylene terephthalate(PET) film as a backside film 304, and a galvalium steel sheet for roof material as a support plate 305. That is, an EMM sheet and the ETFE film are put over a light-receiving surface of the elements 301 and the EMM sheet, the PET film and the support plate are put over their backside, and they are heated at 150 deg.C for 30 minutes using a vacuum laminator while applying pressure and deaerating. Therefore, a solar battery module excellent in weather resistance, heat resistance, moisture resistance, and photoelectric conversion efficiency can be formed.
