Description
Technical field
The invention belongs to application of solar, be specifically related to a kind of concentrating solar photovoltaic generating module.
Background technology
Solar power generation be with solar cell as electrooptical device, be electric energy with solar energy converting.Solar power generation is used widely as a kind of clean energy resource.But the solar energy power generating cost is high at present, becomes to hinder the major reason that solar power generation is promoted.
The typical solar energy photovoltaic power generation module of prior art comprises: the polylith solar cell, and the back side of every solar cell has heating panel, is used for the heat radiation of solar cell; Heating panel is arranged and is installed on the base plate; The front of every solar cell has with it corresponding Fresnel lens (polymethyl methacrylate material), is used to receive solar energy and with the solar cell of solar focusing to correspondence; Solar cell is directly connected by Copper Foil; Fresnel lens is arranged and is installed on the housing; Housing is installed on the base plate.Because tracking accuracy and rigging error, be easy to cause the hot spot after the gathering not exclusively to overlap with solar cell, cause the energy output reduction; The Fresnel lens of polymethyl methacrylate material is easy to aging distortion under exposure in sunshine; The Copper Foil that directly connects battery is easy to rupture or come off under the environment of long-term high low temperature alternation.
Summary of the invention
Problems such as hot spot not exclusively overlaps with solar cell in order to solve, Fresnel lens is easily aging, the Copper Foil easy fracture comes off the object of the present invention is to provide a kind of concentrating solar photovoltaic generating module.Utilize the present invention, sunlight is more accumulated on the solar cell, improved energy output, and can avoid the aging and Copper Foil fracture of Fresnel lens, prolonged the useful life of module.
In order to reach the foregoing invention purpose, the technical scheme that the present invention is adopted for its technical problem of solution provides a kind of concentrating solar photovoltaic generating module, and this device comprises: the polylith solar cell, and the back side of every solar cell has heating panel; Heating panel is arranged and is installed on the base plate; The front of every solar cell has corresponding with it Fresnel lens; Fresnel lens is arranged and is installed on the housing; Housing is installed on the base plate; Connect by Copper Foil between the solar cell; According to the present invention, this device also comprises: also be provided with a top light funnel that the big end is little, inner surface has minute surface between the front of every solar cell and Fresnel lens; The base that light funnel opening is little is connected with the edge in solar cell front.
Above-mentioned smooth funnel can adopt mirror face stainless steel plate or specular aluminium panel material, forms square light funnel by the mirror board of four isosceles trapezoids; Four limits of light funnel bottom and four limits of solar cell are close to.The height of light funnel is no more than 4 times of solar cell diameter.The base material of above-mentioned Fresnel lens is a ultra-clear glasses, after evenly applying silica gel on the substrate, with the mould that has the Fresnel lens screw thread Fresnel lens screw thread is compressed on the silica gel, makes Fresnel lens.The Copper Foil bending of each solar cell circuit of above-mentioned connection is arch.
Concentrating solar photovoltaic generating module of the present invention owing to take above-mentioned technical scheme, reassembles on the solar cell hot spot of skew, thereby has increased energy output; Because Fresnel lens adopts the ultra-clear glasses compound silica gel, has good ageing resistace, operate as normal is more than 15 years in the open air; And the crooked Copper Foil that is arch has increased the surplus of the deformation of expanding with heat and contract with cold, thereby has avoided the fracture of Copper Foil or come off.Therefore, the present invention has obtained beneficial effects such as generating efficiency height, long service life.
Description of drawings
Fig. 1 is the structural representation of concentrating solar photovoltaic generating module of the present invention;
Fig. 2 is the local cross section view that amplifies of Fig. 1.
Be labeled as among the figure: 1-heating panel, 2-solar cell, 3-light funnel, 4-base plate, 5-Copper Foil, 6-housing, 7-Fresnel lens.
Embodiment
Below in conjunction with description of drawings the preferred embodiments of the present invention.
Fig. 1 is the structural representation of concentrating solar photovoltaic generating module of the present invention; Fig. 2 is the local cross section view that amplifies among Fig. 1, and shown in the embodiment of Fig. 1 and Fig. 2, this device comprises:
Polylith solar cell 2, the back side of every solar cell 2 has heating panel 1, is used for the heat radiation of solar cell; Heating panel 1 is arranged and is installed on the base plate 4; The front of every solar cell 2 has with it corresponding Fresnel lens 7, is used to receive solar energy and with the solar cell 2 of solar focusing to correspondence; Fresnel lens 7 is arranged and is installed on the housing 6; Housing 6 is installed on the base plate 4; Above-mentioned Fresnel lens 7, base plate 4 and housing 6 use the bonding formation concentrator solar cell of structure silica gel module.Connect by Copper Foil 5 between the solar cell 2.
According to the present invention, between the front of every solar cell 2 and Fresnel lens 7, also be provided with a top light funnel 3 that the big end is little, inner surface has minute surface.The base that light funnel 3 openings are little is connected with the front of solar cell 2.Sunlight focuses on the solar cell by Fresnel lens 7, and light funnel 3 will reassemble on solar cell after the sunlight reflection of part skew.
For the surplus of deformation being provided for Copper Foil in the process of expanding with heat and contract with cold, Copper Foil 5 bendings of above-mentioned each solar cell of connection are arch, have avoided the fracture of Copper Foil or come off.
Above-mentioned smooth funnel 3 also can adopt mirror face stainless steel plate or specular aluminium panel material, forms the square funnel by the mirror board of four isosceles trapezoids; Four limits of light funnel 3 bottoms and four limits of solar cell are close to; The height of light funnel 3 is no more than 4 times of solar cell diameter.
The base material of above-mentioned Fresnel lens 7 is a ultra-clear glasses, after evenly applying silica gel on the substrate, with the mould that has the Fresnel lens screw thread Fresnel lens screw thread is compressed on the silica gel, makes Fresnel lens.Silica gel has good ageing resistace, and Fresnel lens of the present utility model is operate as normal more than 15 years in the open air.
As mentioned above, concentrating solar photovoltaic generating module of the present invention, owing to increased the use of light funnel, therefore skew gathers on the solar cell again under the reflection of light funnel, thereby has increased energy output according to less than the sunlight on the solar cell originally.Owing to use the good material of silica gel and these two kinds of ageing resistances of ultra-clear glasses to make Fresnel lens, so the ageing resistace of Fresnel lens significantly promotes, and is more suitable in field work.Because the Copper Foil bending is arch,, avoids the Copper Foil fracture or come off therefore for Copper Foil provides surplus when expanding with heat and contract with cold.
