Abstract
The utility model relates to a novel solar battery rear panel which comprises a substrate, an upper weather-proof layer and a lower weather-proof layer, wherein the upper weather-proof layer and the lower weather-proof layer are respectively combined with the substrate by a casting compounding form into an integral laminated structure; each of the upper weather-proof layer and the lower weather-proof layer comprises a base layer, a function layer and a binding layer; and the upper weather-proof layer and the lower weather-proof layer are respectively connected with the substrate by the binding layers. In the utility model, the binding layer is a modified polyethylene layer or an ethyl vinyl acetate layer, thus the binding property of the binding layer and the solar battery rear panel substrate is better compared with a polyvinylidene fluoride film used by the conventional solar battery rear panel; the function layer is a polyvinylidene fluoride layer and is placed at the outermost side of the solar battery rear panel, thus meeting the weather-proof demand of the solar battery rear panel product; and the base layer is a modified polyethylene layer. According to the utility model, all raw materials are not imported, thus reducing the investment cost of the raw materials, and further effectively controlling the fabrication cost of the solar battery rear panel and lowering the production cost of the solar battery rear panel.
Description
Technical field
The utility model relates to a kind of solar cell backboard.
Background technology
At present; Common on the market solar cell backboard is divided into two types: compound and application type; But by market extensively approval be compound backboard because solar cell backboard need encapsulate, protect and insulate producing the chip that photoelectricity transforms, and guarantee that this chip can keep photoelectricity to transform chronically; Therefore require it to have excellent electrical insulating property, resistance is moist, good anti-ultraviolet, acid and alkali-resistance and thermal shock property.It is to make the indispensable critical component of solar module, and the quality of its quality directly influences the efficient and the useful life of solar module.
Typical composite solar battery backboard (also claiming TPT) is to be composited through adhesive means with basic unit (P) by weathering layer (T); Weathering layer adopt have useful life more than 25 years contain the fluorine element film; That basic unit adopts is high pressure resistant, the waterproof sheet material of excellent insulation performance (like PETG, i.e. PET).Wherein, weathering layer is the fluorine film that contains that has excellent weather resistance: like polyvinyl fluoride thin film (E.I.Du Pont Company's supply, commodity are called Tedlar) or polyvinylidene difluoride film (Arkema's supply; Commodity are called Kynar), but because such film is monopolized by external producer always, not only price is higher; And supply shortage manifests serious; Thereby cause holding at high price of solar cell backboard, along with the continuous decline of recent solar module price, the decline of the assembly cost of raw material has become inevitable; Therefore; Contain the fluorine film situation of dependence on import all the time for satisfying the demand that solar components industry cost constantly descends, solving, the solar module industry presses for a kind of reasonable price, delivery cycle stable composite type solar energy can be its adequate and systematic service by battery back-sheet.
The utility model content
The utility model is to the above-mentioned deficiency that existing solar cell backboard exists, and a kind of novel structure is provided, cost is low and the novel solar battery backboard of function admirable.
The technical scheme of the utility model is: a kind of novel solar battery backboard; Comprise matrix, top weathering layer and bottom weathering layer; The layer structure that top weathering layer and bottom weathering layer are combined as a whole through the curtain coating complex method with matrix respectively; Top weathering layer and bottom weathering layer include basic unit, functional layer and tack coat, and the top weathering layer all is connected with matrix through tack coat with the bottom weathering layer.
Preferably, matrix is the PETG layer.
Preferably, basic unit is the modified poly ethylene layer.
Preferably, functional layer is a polyvinylidene fluoride layer.
Preferably, tack coat is modified poly ethylene or Ethyl vinylacetate layer.
The beneficial effect of the utility model is: the utility model connects as one matrix and top weathering layer and bottom weathering layer through the curtain coating complex method, and top weathering layer and bottom weathering layer are provided with basic unit, functional layer and tack coat three-decker, wherein; The top weathering layer is connected with matrix through tack coat with the bottom weathering layer; Tack coat is modified poly ethylene or Ethyl vinylacetate layer, compares with the polyvinylidene fluoride film that conventional solar cell backboard is used, and the caking property of this tack coat and solar cell backboard matrix is better; Functional layer is a polyvinylidene fluoride layer; Be placed on the outermost of solar cell backboard, satisfied the needs of solar cell backboard product weatherability, basic unit is the modified poly ethylene layer; All raw material need not import; Reduce raw-material input cost, thereby effectively controlled the cost of manufacture of solar cell backboard, reduced the production cost of solar cell backboard.
