METHOD FOR MANUFACTURING SOLAR CELL MODULE AND SOLAR CELL MODULE

摘要

Method for manufacturing a solar cell module in which a light-receiving side sealing film 13A and a backside sealing film 13B are each formed of a different resin composition from each other selected from a resin composition A and a resin composition B, both of the sealing films are heated when the pressurizing is initiated so as to reach to a minimum temperature X° C. and a maximum temperature Y° C., the resin composition A has a viscosity of 5.0×104 Pa·s or less at the temperature X° C., and the resin composition B has a viscosity of 7.0×104 Pa·s or less at the temperature X° C. and has a viscosity of 2.0×104 Pa·s or more at the temperature Y° C.

1. A method for manufacturing a solar cell module comprising the steps of stacking a light-receiving side transparent protective member, a light-receiving side sealing film, a photovoltaic element, a backside sealing film and a backside protective member in this order to obtain a stack, and heating and pressurizing the stack to integrate the stack, wherein
the light-receiving side sealing film and the backside sealing film are each formed of a different resin composition from each other selected from a resin composition A and a resin composition B, both of the sealing films are heated when the pressurizing is initiated so as to reach to a minimum temperature X° C. and a maximum temperature Y° C., the resin composition A has a viscosity of 5.0×104 Pa·s or less at the temperature X° C., and the resin composition B has a viscosity of 7.0×104 Pa·s or less at the temperature X° C. and has a viscosity of 2.0×104 Pa·s or more at the temperature Y° C.
