Description
Technical field
The utility model relates to area of solar cell, is a kind of double-sided solar photovoltaic module specifically.
Background technology
The solar module of prior art generally comprises glass cover-plate, solar battery sheet and backboard, between above each layer, through EVA glued membrane, bonds.Generally speaking, solar module light-receiving area is larger, and the electric weight of generation is just more.Solar module is only accepted the irradiation of a sunlight at present, and consequent electric weight is the electric power of solar module one side.The cell piece that is the solar photovoltaic assembly of prior art is full wafer, and can only one side be subject to light, thereby also cannot fully generate electricity.Cell piece material used is expensive semi-conducting material, and the energy output that semi-conducting material unit are produces has directly affected the utilance of semi-conducting material, that is to say, the stock utilization of the solar battery sheet of prior art is low, and generating efficiency is not high.
Utility model content
The technical problems to be solved in the utility model is that a kind of double-sided solar photovoltaic module that can improve utilance and the generating efficiency of cell piece is provided.
Technical solution of the present utility model is, a kind of double-sided solar photovoltaic module of following structure is provided, comprise glass cover-plate, silicon cell and backboard, between glass cover-plate, silicon cell and each layer of backboard, through EVA glued membrane, bond from top to bottom, between described silicon cell and backboard, be provided with reflective aluminum film, described silicon cell comprises multi-disc fine strip shape silicon, gapped between adjacent two fine strip shape silicon.
Adopt above structure, the utility model compared with prior art has the following advantages: adopt the utility model structure, sunlight is irradiated on silicon cell through glass cover-plate, positive fine strip shape silicon materials are subject to after light, can make cell piece produce electric weight, due to gapped between adjacent two fine strip shape silicon, high strength reflector has certain thickness, thereby solar energy is shining in high strength reflector from gap, high strength reflector is subject to after light the back side to fine strip shape silicon by light reflection, thereby also can utilize luminous energy to produce electric weight; This product has increased the electric weight that unit silicon materials produce effectively, the solar module that energy output is identical, and this product can be saved the use of silicon materials, has reduced the production cost of solar module; And with the solar module of same silicon material, this product can produce the energy output that doubles prior art, has improved generating efficiency.
As improvement, between glass cover-plate and silicon cell, be provided with antireflecting coating, arranging of antireflecting coating is mainly to reduce glass cover-plate to sun reflection of light, thereby improve, irradiates the sunlight intensity on cell piece.
As improvement, the width of described fine strip shape silicon is 3-5 mm, in order to utilize more fully silicon materials, selects this technical scheme can improve silicon materials utilance.
As improvement, the thickness of described reflective aluminum film is 3-5 mm, and the gap between described adjacent two fine strip shape silicon is 5-20mm, and this size design can guarantee that high strength reflection physical efficiency receives sufficient sunlight, thereby reflexed to the back side of fine strip shape silicon, increased its energy output.
Accompanying drawing explanation
Fig. 1 is the structural representation of double-sided solar photovoltaic module of the present utility model.
As shown in the figure 1, glass cover-plate, 2, silicon cell, 3, backboard, 4, reflective aluminum film, 5, gap, 6, antireflecting coating.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, silicon solar battery assembly of the present utility model, comprise glass cover-plate 1, silicon cell 2 and backboard 3, between glass cover-plate 1, silicon cell 2 and backboard 3 each layers, through EVA glued membrane, bond from top to bottom, between described silicon cell 2 and backboard 3, be provided with reflective aluminum film 4, described silicon cell 2 comprises multi-disc fine strip shape silicon, between adjacent two fine strip shape silicon gapped 5; The width of described fine strip shape silicon is 3-5 mm.
Between glass cover-plate 1 and silicon cell 2, be provided with antireflecting coating 6, arranging of antireflecting coating is mainly to reduce glass cover-plate to sun reflection of light, thereby improve, irradiates the sunlight intensity on cell piece and reflective aluminum film.
The thickness of described reflective aluminum film 4 is 3-5 mm, and the gap 5 between described adjacent two fine strip shape silicon is 5-20mm, and the scope in above gap is the width range of IDS.
Fig. 1 adopts the mode of stagewise cutaway view, thereby can each layer of structure of more clear demonstration.
Below only with regard to the utility model preferred embodiment, be described, but can not be interpreted as it is limitations on claims.The utility model is not only confined to above embodiment, and its concrete structure can change, as fine strip shape silicon is not limited to above-mentioned size; The material of high strength reflector also can change, etc.In a word, all various variations of doing in the protection range of the utility model independent claims are all in protection range of the present utility model.
