Abstract
The utility model relates to a solar cell module. The a solar cell module comprises glass, an EVA packaging layer, a back plate, solar energy cell pieces and a light condensing system. The light condensing system wraps a prismatic structure located on the glass and a lens on the solar energy cell piece. The prismatic structure reflects the light going to the prismatic structure to the lens on the solar energy cell piece close to the prismatic structure. The reflected light irradiates onto the solar energy cell piece below vertically after refraction of the lens. The solar cell module decrease the usage number of the solar energy cell pieces to 1/4 of the usage number in the prior art, and lowers the probability of problems of hidden cracks, edge breakage, broken corners, chips and the like of the cell pieces during the packaging process greatly. The repair rate of the module is 20-30% of the repair rate of the prior art, and therefore the manufacturing cost of the solar cell module is lowered greatly. In addition, the solar cell module is reasonable in design, is simple in structure, has low cost, and is helpful for industrialization production.

Technical field
The utility model relates to the making field of solar cell chip module, is specifically related to a kind of solar module.
Background technology
For adapting to the harsher demand in photovoltaic market, in improving constantly battery component conversion efficiency, reduce the cost of solar module and also paid close attention to more and more widely.The crystal silicon solar cell sheets that adopt in solar module manufacturing process at present more, because the cost of manufacture of crystal-silicon battery slice is high, and in encapsulation process, easily there is the hidden situations such as limit, unfilled corner, fragment of splitting, collapse, reduced greatly solar module rate of finished products.Cause like this manufacturing cost of solar module high, greatly restricted the extensive use of solar power generation.
Summary of the invention
The purpose of this utility model is exactly a kind of solar module that the defect for overcoming above-mentioned prior art existence provides.The utility model has reduced the use amount of solar battery sheet, has reduced the generation of defective products, thereby has significantly reduced the manufacturing cost of solar module; In addition, it is reasonable in design, simple in structure, and cost is low, is conducive to industrialization and produces.
A kind of solar module technical scheme of the present utility model is to comprise successively backboard, EVA encapsulated layer and solar battery sheet wherein, glass and condenser system by shady face to sensitive surface.
Described condenser system comprise be positioned at glass top prismatic structure and solar battery sheet directly over lens.
Described prismatic structure is four prisms of the minute surface composition of four sides reflection ray.Described prismatic structure will be mapped to light reflection above it to the lens of the solar battery sheet top being adjacent.After the refraction of reverberation scioptics, vertical irradiation is to the solar battery sheet of its below.
Minute surface is the reflectorized materials such as reflective fabric, reflective lattice sheet or reflection picture spraying cloth.
Described prismatic structure bottom is square structure, and its length of side is 0.1～200mm, is preferably 125 ± 2mm and 156 ± 2mm.
Described prismatic structure height is 0.1～200mm.
Described lens are Fresnel Lenses.
Described Fresnel Lenses thickness is 0.1～10mm.
Described Fresnel Lenses thickness is preferably 1 ± 0.1mm.
The beneficial effects of the utility model are: the utility model adopts novel structure, introduce condenser system, to be mapped to light reflection above it to the Fresnel Lenses of the solar battery sheet top being adjacent by the prismatic structure with reflection action, reverberation by Fresnel Lenses, the incident light of different directions is penetrated with directional light from opposite side and vertical irradiation to the solar battery sheet of its below.The utility model not only use amount of solar battery sheet is reduced to 1/4 of prior art, and greatly reduce cell piece and in encapsulation process, occur the hidden probability that splits, collapses the problems such as limit, unfilled corner, fragment, assembly repair rate is 20～30% of prior art, thereby improve to a certain extent solar module rate of finished products, reduced the cost of solar module; In addition, it is reasonable in design, simple in structure, and cost is low, is conducive to industrialization and produces.
