Problems solved by technology

At present, some manufacturers of solar thin film battery modules have adopted butyl sealant (hot melt adhesive with polyisobutylene and polyisoprene as the main body and inorganic filler) to prevent moisture in the air from penetrating, although butyl The glue has a low gas transmission rate and has a good preventive effect on water vapor penetration. However, due to the poor adhesion of butyl sealant to two pieces of glass, the solar cells are impacted, vibrated, outdoor high and low temperature cycles, and ultraviolet rays. During the irradiation process, it is easy to lose the cohesiveness, thus losing the protective function

Embodiment

[0021] An amorphous silicon cell assembly, characterized in that the cell assembly is sequentially connected by a glass substrate 1, a transparent electroplating layer 2, an amorphous silicon layer 3, an aluminum film back sheet pole layer 4 and an adhesive layer 5, and the amorphous silicon layer 3 1. The surroundings of the electrode layer 4 of the aluminum film back sheet and the bonding layer 5 are sealed with a sealant layer 1 6 and a sealant layer 2 7 to form an amorphous silicon cell assembly.

[0022] The amorphous silicon layer is an amorphous silicon layer doped with boron atoms and phosphorus atoms.

[0023] The pole layer of the aluminum film back sheet is an aluminum layer or an alloy layer of aluminum and silver.

[0024] The bonding layer is an ethylene vinyl acetate copolymer layer (EVA) or a polyvinyl butyral resin layer (PVB).

[0025] The first six layers of sealant layer are hot-melt adhesives with polyisobutylene and polyisoprene as the main body and inor...

Abstract

The invention discloses a novel amorphous silicon cell component. The cell component is characterized by comprising a glass substrate (1), a transparent electroplated layer (2), an amorphous silicon layer (3), an aluminum film back sheet pole layer (4) and an adhesive layer (5) which are connected in turn, wherein a sealing glue layer 1 (6) and a sealing glue layer 2 (7) are used for sealing around the amorphous silicon layer (3), the aluminum film back sheet pole layer (4) and the adhesive layer (5) to form the amorphous silicon cell component. Since two sealing modes are adopted, a solar thin film cell is effectively protected from erosion of substances such as external steam, dust and the like.
