PURPOSE:To avoid the temperature rise of a solar battery module and avoid the decline in open voltage by a method wherein a sealing layer, which encloses a solar battery element, is composed of a light transmitting layer which has light passages and a highly heat-conductive layer which introduces the heat in the sealing layer to the outside. CONSTITUTION:A highly heat-conductive sheet 12 made of heat-conductive resin obtained by mixing about 100 parts of epoxy system resin with a thermal conductivity of 10<-4>CaL/cm.sec. deg.C and 1-5 parts of other synthetic resin, a solar battery element 11, a light transmitting sheet 14 made of EVA resin or the like and a glass substrate 15 are successively laminated with upper and lower electrodes 21 and 22 on the upper and lower surface of the solar battery element 11 respectively and are heated under a depressurized atmosphere in an enclosing container. Then the depressurization is released and the laminated layers are compressed to adhere by the pressure difference between the atmospheric pressure and the reduced pressure to form a solar battery module. |
