A heat-laminated resin such as polyvinyl fluorite (PVF), which is sandwiched between two volant sheets 2, and further coats both sides of a light-receiving surface glass 3 and a metal foil such as aluminum that blocks the intrusion of moisture. A water-repellent back plate 4 consisting of the above-mentioned materials is combined together, and then hermetically sealed by vacuum thermocompression processing to form an integrated structure. At this time, only the peripheral end surface of the pottant 2 is exposed.

モジュールは完成する。The potant 2 described above has hygroscopic properties and becomes devitrified or colored due to moisture absorption. Devitrification and discoloration of the potant cause a fatal functional decline in the solar cell module, so
Waterproofing treatment is applied to all edges. As a processing method, a moisture barrier material 5 such as butyl rubber and a gasket 6 having a cross-sectional shape for protecting the moisture barrier material 5 are coated and attached, and the solar cell module is completed.

。However, if such a solar cell module is installed outdoors for a long period of time, the surface of the light-receiving surface glass 3 becomes dirty, the light transmittance decreases, and the electrical output decreases accordingly. Staining of the glass surface is due to the accumulation of dirt substances on the glass surface. Dirt substances that have temporarily adhered to the entire surface of the glass are washed away by rainwater and blocked by edges 7 consisting of moisture barrier material 5 and gasket 6 located around the solar cell module, where they form a deposited layer 8.

On the other hand, on the light-receiving surface of the lath 3, for example, a polyester adhesive tape 10 having a width of 3 to 7 m is pasted in advance along the periphery of the button contact surface. Similarly,
For example, polyvinyl fluorite (PV') is coated on both sides of metal foil such as aluminum to block moisture ingress
A polyester adhesive tape 1 is also applied to the potting contact surface side of the water-repellent back plate 4 made of heat-laminated resin such as F).
