Abstract
The utility model discloses a solar cell assembly. An upper cover plate, an adhesive layer, a solar cell sheet layer and a lower encapsulation layer are bonded and are encapsulated from top to bottom so as to form the solar cell assembly, wherein the lower encapsulation layer is a TPE backplane. The thickness of an EVA layer in the TPE backplane is in a range from 80 micro M to 150 micro M. According to the solar cell assembly of the utility model, the consumption of EVA is decreased, so the solar cell assembly is lower in cost.
Description
Technical field
The utility model belongs to area of solar cell, relates in particular to solar module.
Background technology
Solar cell power generation is to utilize the photoelectric effect of silicon semiconductor material directly light energy conversion to be become the device of electric energy; because if silicon wafer is directly exposed in the air; the efficient of its light energy conversion city electric energy can decay, and therefore will adopt transparent protective film that solar battery sheet is encapsulated.Thereby the structure that adopts at present is followed successively by from top to bottom upper cover plate glassy layer, upper EVA layer, solar cell lamella, lower EVA layer and backsheet layer the solar cell lamella is encapsulated, because the basic dependence on import of EVA, therefore expensive, therefore the assembly cost of this structure is higher, is unfavorable for market competition.
The utility model content
The utility model purpose: for the problem and shortage of above-mentioned existing existence, the purpose of this utility model provides a kind of low-cost solar battery component.
Technical scheme: for realizing above-mentioned utility model purpose, the utility model is by the following technical solutions: a kind of solar module, by upper cover plate, adhesive linkage, solar cell lamella and lower encapsulated layer from top to bottom successively bonding encapsulation form, described lower encapsulated layer is the TPE layer, this TPE layer and the contacted face of described solar cell lamella scribble the EVA film, and described EVA film thickness is 80～150 μ m.
With respect to prior art, owing to saved one deck EVA, therefore, cost significantly reduces.For example, produce the 100MW assembly, approximately save 1,000 ten thousand yuan of costs.Because the backboard that uses is the TPE structure, therefore, also has certain adhesion strength behind lamination, also can satisfy quality requirement.
Adopt coating thickness be the TPE backboard of 80～150 μ m EVA glued membranes as lower encapsulated layer, to guarantee tack coat and backboard stronger adhesion strength is arranged.
As preferably, described upper cover plate material is glass, and described adhesive linkage material is EVA.
Beneficial effect: compared with prior art, the utlity model has following advantage: owing to save the use amount of EVA, cost is lower.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment only is used for explanation the utility model and is not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.
As shown in Figure 1, a kind of solar module, the upper cover plate 1 that glass is made, adhesive linkage 2, solar cell lamella 3 and the lower encapsulated layer 4 of EVA material from top to bottom successively bonding encapsulation form, above-mentioned lower encapsulated layer 4 backboard that is TPE structures wherein, EVA film thickness in this TPE backboard is 100 μ m, so that lower encapsulated layer energy 4 is bonding firm with solar cell lamella 3, provide enough adhesive strengths.
The above by reference to the accompanying drawings preferred specific embodiment of described the present invention only is used for the explanation embodiments of the present invention; rather than as the restriction to aforementioned goal of the invention and claims content and scope; any simple modification, equivalent variations and modification that every foundation technical spirit of the present invention is done above embodiment all still belong to the technology of the present invention and rights protection category.
