Abstract

The utility model relates to the technical field of solar cells, and specifically relates to a novel solar cell backboard film. The solar cell backboard film comprises an insulation base layer, an anti-gas layer, a waterproof layer, polyurethane adhesive layers and tempered glass. The upper surface of the insulation base layer is covered with the anti-gas layer, and the lower surface of the insulation base layer is covered with the waterproof layer. The insulation base layer is fixedly connected with the anti-gas layer and the waterproof layer through the polyurethane adhesive layers. The tempered glass is arranged on the anti-gas layer, the anti-gas layer is made of aluminum foil, and the waterproof layer is made of silane waterproof agents. The novel solar cell backboard film has simple, compact and reasonable structure, is convenient and rapid to assemble, is firmly connected, has very low permeability rate, has strong tension force between layers, and has high stripping strength. By employing the novel solar cell backboard film, water absorption capability of a cell sheet is reduced, steam is effectively obstructed, service lifetime of a solar cell is prolonged, and the work reliability of the solar cell is greatly improved, so the solar cell backboard film is easy to popularize.

Description

The novel solar battery backboard film
Technical field
The utility model relates to a kind of technical field of solar cell, especially a kind of novel solar battery backboard film.
Background technology
Flourish along with solar cell industry more and more is subject to industry as the backboard membrane of one of encapsulating material that is applied to solar cell and pays close attention to.Topmost solar module as the solar photoelectric utilization is to be formed by the vacuum heat seal by high efficiency crystalline silicon solar cell, ultrawhite woven design toughened glass, EVA, crystalline silicon and notacoria, and notacoria plays a part skeleton and the crystal silicon body is protected.Existing solar cell backboard film permeability rate is high, and water resistance is poor, and the battery back-sheet film is easily delamination in use, has shortened the useful life of solar cell.
The utility model content
Existing solar cell backboard film permeability rate is high in order to overcome, easy delamination and useful life short deficiency, the utility model provides a kind of novel solar battery backboard film.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of novel solar battery backboard film, comprise insulated substrate, gas barrier layer, watertight composition, polyurethane binder layer and toughened glass, the insulated substrate upper surface is covered with one deck gas barrier layer, lower surface is covered with one deck watertight composition, insulated substrate is fixedly connected with watertight composition with gas barrier layer by polyurethane binder layer, and gas barrier layer is provided with toughened glass.
According to another embodiment of the present utility model, comprise that further described gas barrier layer is aluminium foil layer.
According to another embodiment of the present utility model, comprise that further described watertight composition is silane waterproofing agent layer.
The beneficial effects of the utility model are, this novel solar battery backboard membrane structure is simple, compact and rationally, easy to assembly quick, connection is reliable, reduced the water absorption of cell piece, can effectively intercept steam, permeability rate is extremely low, and pulling force is large between layers, peel strength is large, extended the useful life of solar cell, greatly improved the reliability of solar cell working, be easy to use and promote.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. insulated substrate in figure, 2. gas barrier layer, 3. watertight composition, 4. polyurethane binder layer, 5. toughened glass.
Embodiment
Structural representation of the present utility model as Fig. 1, a kind of novel solar battery backboard film, comprise insulated substrate 1, gas barrier layer 2, watertight composition 3, polyurethane binder layer 4 and toughened glass 5, insulated substrate 1 upper surface is covered with one deck gas barrier layer 2, lower surface is covered with one deck watertight composition 3, and insulated substrate 1 is fixedly connected with watertight composition 3 with gas barrier layer 2 by polyurethane binder layer 4, and gas barrier layer 2 is provided with toughened glass 5, described gas barrier layer 2 is aluminium foil layer, and described watertight composition 3 is silane waterproofing agent layer.
During use, insulated substrate 1 upper surface is covered with one deck gas barrier layer 2, described gas barrier layer 2 is aluminium foil layer, can effectively intercept steam, and lower surface is covered with one deck watertight composition 3, described watertight composition 3 is silane waterproofing agent layer, reduced the permeability rate of backboard membrane, insulated substrate 1 is fixedly connected with watertight composition 3 with gas barrier layer 2 by polyurethane binder layer 4, has strengthened peel strength between layers, gas barrier layer 2 is provided with toughened glass 5, has strengthened the mechanical strength of battery back-sheet film.This novel solar battery backboard membrane structure is simple, compact and reasonable, easy to assembly quick, connect reliably, reduced the water absorption of cell piece, can effectively intercept steam, permeability rate is extremely low, pulling force is large between layers, and peel strength is large, has extended the useful life of solar cell, greatly improved the reliability of solar cell working, be easy to use and promote.
