Patent ID: 7749351

Claim:
A method of producing a solar cell module having a laminating step, in which a body to be laminated comprising of photovoltaic devices and a sealing member is mounted on a mounting board heated at a predetermined temperature and the body to be laminated is heat-bonded by pressing with a diaphragm, the method comprising the steps of: mounting the body to be laminated on a tabular member; carrying in the body to be laminated along with the tabular member onto the mounting board; heat-bonding the body to be laminated by pressing using the diaphragm; carrying out the body to be laminated along with the tabular member from the mounting board after separating the diaphragm from the body to be laminated; and separating the body to be laminated from the tabular member, wherein the diaphragm is provided opposite to the mounting board heated at a predetermined temperature, and the diaphragm applies pressure on the body to be laminated which is sandwiched between the diaphragm and the mounting board, wherein the diaphragm is directly cooled by a fan after carrying out the body, wherein another body to be laminated is carried in along with another tabular member onto the mounting board after cooling the diaphragm, and wherein a release sheet is arranged between the tabular member and the body to be laminated, and the release sheet has an irregular form on a surface for allowing efficient ejection of air from the body.
