  • Publication number: 20210066530
    Abstract: A manufacturing method of a solar cell module according to an embodiment of the present disclosure includes a laminating process. The laminating process includes bringing a stack of overlapped elements of a solar cell module into a chamber, setting the stack on a hot plate, and heating the stack while pressing the stack with a pressing member. In the laminating process, the temperature of the pressing member is controlled by maintaining at least an entire contact portion of the pressing member, which is to be in contact with the stack, in contact with the upper chamber or the hot plate, or out of contact with the upper chamber and the hot plate. The temperature control is performed in a stand-by state before the stack is brought into the chamber.
