SHEET FOR SOLAR CELL SEALING

摘要

PURPOSE: A sheet for encapsulating material of a solar battery is provided to improve thermal shrinkage ratio and flexibility by being formed by welding a part of heat adhesive resin powder and to improve productivity by reducing defective products. CONSTITUTION: A surface side protection member(1) consisting of the glass is prepared. A sheet(4) for encapsulating material located on the surface of the surface side protection member. A plurality of solar cell devices(3) locates on the sheet for the encapsulating material. The sheet for the encapsulating material locates on the solar cell device. A backside protection member(2) locates on the sheet for the encapsulating material. The apparent density of the sheet for the encapsulating material is 20 to 70% of net density of a heat adhesive resin.
