Abstract
A solar battery module and manufacturing method for a solar battery module having improved output are provided. The solar battery module 1 is a transparent substrate 10, transparent resin layer 13b, solar battery cell 12, colored resin layer 13a and back sheet 11 laminated in this order. The light-receiving surface 12a of the solar battery cell 12 faces the transparent resin layer 13b side. The backside 12b of the solar battery cell faces the colored resin layer 13a. The MFR [melt flow rate] of the transparent resin layer 13b is lower than the MFR of the colored resin layer 13a.
Claims14
A manufacturing method for a solar battery module, the method comprising:
- forming a laminate of a transparent substrate, a transparent resin sheet, a solar battery cell unit, a colored resin sheet, and a back sheet in this order a light receiving surface of the solar battery cell unit facing the transparent resin sheet;
- and
- heating the laminate, wherein
- a melt flow rate, MFR, of the transparent resin sheet is lower than an MFR of the colored resin sheet,
- a resin of the transparent resin sheet consists of copolymers of ethylenically unsaturated silane compounds and α-olefins, and
- a resin of the colored resin sheet consists of at least one selected from the group consisting of ethylene-vinyl acetate copolymers, ethylene-ethyl acrylate copolymers, silicone resins, epoxy resins, polyvinyl butyral, ethylene vinyl alcohol copolymers, acrylic resins, polyethylene, and polypropylene.
