PURPOSE:To prevent the lowering of a photoelectric conversion output, and to maintain the insulating properties of a solar cell element and a rear protective film by heating and pressing a resin layer only in the peripheral margin section of the solar cell element and bonding a substrate and the rear protective film. CONSTITUTION:A recessed pressure body 6 and a heating body 7 are lifted previously by an air cylinder 10, and the pressure body 6 is heated beforehand by the heating body 7 so that the temperature of the pressure body 6 is kept at the melt temperature or more of a resin. A solar cell element 1 is positioned precisely so that the projecting section of the pressure body 6 is brought into contact only with the peripheral margin section 3 of the element 1 when the pressure body 6 is brought down, and a resin layer 4 is positioned downward onto the element 1 so that the whole substrate 2 is coated with a rear protective film 5. The pressure body 6 is lowered by the air cylinder 10, and fast stuck to the rear protective film 5. The air cylinder 10 is elevated, and the resin is cooled slowly until it is cured. Accordingly, the solar cell element 1 is not heated, thus preventing the lowering of the photoelectric conversion output of the solar cell 1. |
