Abstract
The utility model relates to the technical field of solar cells, and especially relates to a TPT back film structure. The TPT back film structure includes a PET thick film, EVA films, fluorine films, a silicon wafer and glass. The fluorine films are composed of an upper fluorine film and a lower fluorine film. The PET thick film is arranged between the upper fluorine film and the lower fluorine film. The EVA films, composed of an upper EVA film and a lower EVA film, are disposed below the lower fluorine film. The silicon wafer is arranged between the upper EVA film and the lower EVA film. The glass is arranged below the lower EVA film. The TPT back film structure is simply structured and uses a double-faced fluorine-containing back film, and thus the excellent performance of the back film is ensured.
Description
Technical field
The utility model relates to a kind of notacoria, relates in particular to a kind of TPT notacoria structure.
Background technology
Require in useful life of current commercial crystal silicon solar batteries assembly be 25 years and notacoria as the photovoltaic encapsulation material directly contacting with external environment large area, should there is excellent weatherability, resistance to insulating properties, impact resistance and steam barrier.These excellent properties are very important to ensureing reliability, stability, the durability of solar cell.Otherwise there is the bad phenomenon such as delamination, be full of cracks, foaming, yellowing as film, can cause the situations such as battery module comes off, cell piece slippage, the reduction of battery effective output.
Summary of the invention
The technical problems to be solved in the utility model is: when existing notacoria cannot reach excellent quality, easily there is the bad phenomenon such as delamination, be full of cracks, foaming, yellowing, can cause the situations such as battery module comes off, cell piece slippage, the reduction of battery effective output, a kind of TPT notacoria structure is provided.
In order to overcome the defect existing in background technology, the utility model solves the technical scheme that its technical problem adopts: this TPT notacoria structure comprises PET thick film, EVA glued membrane, fluorine film, crystal silicon chip and glass, described fluorine film is divided into two-layer up and down, between fluorine film levels, PET thick film is set, the below of described lower floor fluorine film arranges EVA glued membrane, described EVA glued membrane is divided into two-layer up and down, between described EVA glued membrane is upper and lower two-layer, is provided with crystal silicon chip, below the EVA of lower floor glued membrane, is provided with glass.
The beneficial effects of the utility model are: this TPT notacoria structure is simple in structure, has used two-sided fluorine-containing notacoria, has ensured the excellent properties of notacoria.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Wherein: 1, PET thick film, 2, EVA glued membrane, 3, fluorine film, 4, crystal silicon chip, 5, glass.
Embodiment
Fig. 1 is structural representation of the present utility model, figure comprises PET thick film 1, EVA glued membrane 2, fluorine film 3, crystal silicon chip 4 and glass 5, fluorine film 3 is divided into two-layer up and down, between fluorine film 3 levels, PET thick film 1 is set, the below of lower floor's fluorine film 3 arranges EVA glued membrane 2, described EVA glued membrane 2 is divided into two-layer up and down, between EVA glued membrane is two-layer Shang Xia 2, is provided with crystal silicon chip 4, below the EVA of lower floor glued membrane 2, is provided with glass 5.
At the two-sided fluorine film 3 that is provided with of PET thick film 1, it is simple in structure, has ensured reliability, stability and the durability of solar cell.
This TPT notacoria structure is simple in structure, has used two-sided fluorine-containing notacoria, has ensured the excellent properties of notacoria.
