摘要:
The present invention aims to provide a method for manufacturing a solar cell module capable of improving positioning accuracy of solar cell elements relative to a light reflection plate. When a solar cell module is manufactured, a corrugated light reflection plate 4 is first prepared by bonding a thermoplastic resin film 7 to a plastic substrate 6. Subsequently, the light reflection plate 4 is set on a lower mold 10, and a thick resin sheet 12 made from an encapsulation resin is arranged on the light reflection plate 4. Then, vacuum suctioning and hot-press processing are performed sequentially, whereby a precursor assembly 13 is formed with the light reflection plate 4 and the resin sheet 12 attached together. Subsequently, a plurality of solar cell elements 2 is placed on an upper surface of the precursor assembly 13. Then, a thin resin sheet 14 made from the encapsulation resin is arranged on the solar cell elements 2, and a front surface plate 3 is arranged on the resin sheet 14. Subsequently, a cross-linking reaction of the encapsulation resin proceeds with a dry laminator, thus the respective solar cell elements 2 are laminated.

Disclosed is a solar cell module which can collect solar light to a solar cell, while reducing accumulation of dusts and particles. The solar cell module is provided with a plurality of bifacial solar cells. The solar cells are coated together with a sealing film formed of a sealing resin material. A front surface side transparent board is bonded on the upper surface in the gravity direction, i.e., the front surface of the sealing film. On the front surface side of the front surface side transparent board, a lenticular lens is arranged for collecting solar light to a solar cell by refracting solar light entered from the front surface side of the solar cell module. On the lower surface in the gravity direction, i.e., the rear surface, of the sealing film, a rear surface side transparent board is bonded. On the rear surface side of the rear surface side transparent board, an uneven reflection film is arranged for reflecting solar light entered from the front surface side of the solar cell module and collecting the light to the solar cell.
