Abstract
The utility model relates to a non-fluorine weather-resistance solar battery back film, which comprises a base material. The non-fluorine weather-resistance solar battery back film is characterized in that a high-weather-resistance polyethylene terephthalate (PET) layer is arranged on one surface of the base material, and a polyolefin layer is arranged on the other surface of the base material; the base material is connected with the high-weather-resistance PET layer through a first adhesive layer; the base material is connected with the polyolefin layer through a second adhesive layer; the thickness of the high-weather-resistance PET layer is 30 to 100 micrometers; the thicknesses of the first adhesive layer and the second adhesive layer are respectively 5 to 15 micrometers; the thickness of the base material is 100 to 300 micrometers; and the thickness polyolefin layer is 20 to 150 micrometers. The non-fluorine weather-resistance solar battery back film has the advantages that the high-weather-resistance PET layer on the outmost layer (the spatial surface) of the back film is high in ultraviolet resistance and hydrolysis resistance and can be adhered to other materials easily; the poly-p-phenylene oxide (PPO) base material (or polyphenyl ether) on the inner layer is extremely excellent in hydrolysis resistance, electrical insulation performance and mechanical performance; and therefore, the cost of the back film can be effectively reduced; and the back film is extremely excellent in hydrolysis resistance.
Description
Technical field
The utility model relates to a kind of solar cell notacoria, the high weather resistant solar cell of especially a kind of non-fluorine notacoria.
Background technology
Present domestic crystal silicon solar battery component package mainly contains two types of multiple membranous type (weathering layer material etc. is bonded through glue with base material) and application types (on base material, directly applying one deck fluorine-containing coat) with notacoria; But which kind of its all be that weathering layer in air surface adopts fluorine material as weathering layer; (polyester: ethylene glycol terephthalate) as the intermediate layer base material, base material mainly plays the performance that intercepts steam, electric insulating quality, mechanics support to adopt the PET material.At present, the fluorine material cost is too high, and and is difficult to carry out bonding (the fluorine material surface energy is very low, is difficult to other materials bonding) through binding material with the base material of centre.The problem of the PET base material ubiquity anti-hydrolytic performance difference of notacoria employing now, this directly affects the serviceability of whole notacoria.
The utility model content
The purpose of the utility model is to overcome the deficiency that exists in the prior art, and the high weather resistant solar cell of a kind of non-fluorine notacoria is provided, and can effectively reduce cost, and have extremely excellent anti-hydrolytic performance.
According to the technical scheme that the utility model provides, the high weather resistant solar cell of a kind of non-fluorine notacoria comprises base material, and characteristic is: the one side at said base material is provided with high weather-proof pet layer, at the another side of base material polyolefin layer is set; Connect by first tack coat between said base material and the high weather-proof pet layer, connect by second tack coat between said base material and the polyolefin layer.
The thickness of the weather-proof pet layer of said height is 30～100 μ m.
The thickness of said first tack coat and second tack coat is 5～15 μ m.
The thickness of said base material is 100～300 μ m.
The thickness of said polyolefin layer is 20～150 μ m.
The advantage of the utility model: the high weather-proof PET of the outermost layer of notacoria (space face) has excellent anti-ultraviolet and anti-hydrolytic performance, and is prone to bonding with other materials.The PPO base material (polyphenylene oxide) of internal layer has extremely excellent anti-hydrolytic performance, electrical insulation properties, mechanical property.Therefore, this notacoria can effectively reduce cost, and has extremely excellent anti-hydrolytic performance.
