Solar cell
Technical field
The invention belongs to the solar energy generation technology field, particularly relate to a kind of solar cell.
Background technology
In the prior art, the main solar panel of solar cell constitutes, solar panel adopts compositions such as battery sheet, module frame, toughened glass, encapsulating material and terminal box, wherein the battery sheet adopts the device of crystal silicon solar battery component as opto-electronic conversion, its photoelectric conversion rate has only about 13%, the utilance of solar energy is lower, and the unit required cost height that generates electricity is unfavorable for the penetration and promotion of solar cell; In a lot of photovoltaic systems, when light intensity was more weak, the photovoltaic application system was difficult to export energy, when increase sunshine, the efficient of photovoltaic display increases within the specific limits, and simultaneously, photovoltaic battery temperature can increasing and increase with luminosity, generally need to increase in addition cooling device, cause efficient to reduce, and the photovoltaic cell area need big speculum or lens area when big, bring difficulty to production, expensive simultaneously increasing.
Summary of the invention
The object of the present invention is to provide a kind of simple in structure, energy conversion rate is high, the solar cell being convenient to popularize.
The objective of the invention is to adopt such technical solution to realize: it comprises solar panel, it is characterized in that the heat abstractor that is provided with of described solar panel, and be provided with concentration module on heat abstractor.
The present invention adopts the structure that sets gradually heat abstractor and concentration module on solar panel, its reasonable in design, overcome the existing in prior technology defective, improved light energy use efficiency, for advantage has been created in the universal and popularization of solar cell.

Embodiment
With reference to Fig. 1: the present invention includes solar panel 6, described solar panel 6 be provided with heat abstractor 1, and on heat abstractor 1, be provided with concentration module 2; Solar panel 6 is formed by connecting in known manner by battery sheet, module frame, toughened glass, encapsulating material and terminal box etc.; Described heat abstractor 1 is made up of cooling liquid bath 7, input pipe 3 and efferent duct 5, and cooling liquid bath 7 is made by two-layer low iron ultrawhite guiding principle glass, two-layer between formation highly be the appearance water volume space of 6mm, the thickness of described low iron ultrawhite guiding principle glass is 3mm; Described input pipe 3, efferent duct 5 are arranged on the side of cooling liquid bath 7, the aperture of described input pipe 3, efferent duct 5 is: 3-5mm, the frame of the frame of described cooling liquid bath 7 and solar panel 6 fixes, side at cooling liquid bath 7 scribbles fluorescent material 4, be used for reflected solar energy astigmatism light, improve the absorption of astigmatic light, cooling liquid bath 7 can be by the end bundle pipes and the solar panel radiating groove of the attached a little higher than photovoltaic cell height of liquid level outward, utilize the be heated principle of light specific gravity of water, form self-loopa and save energy loss; Described concentration module 2 is positioned at heat abstractor 1 top, and described concentration module 2 is arranged in parallel by the lonely type polymethyl methacrylate of at least three waves concentrators and forms the concentrator group and constitute, with the dimensional requirement of the solar module that satisfies the different capacity size; According to transmission and refraction principle, condensing glass can be assembled 100 times of expansions with solar energy, and according to 125*125mm battery sheet characteristic, it is maximum that the optically focused of 250-270mm length scatters to the battery sheet; Because concentration module 2 is positioned at cooling liquid bath 7 tops, collector lens in the concentration module 2 can have the deflection of certain angle, the deflection of collector lens is controlled by the solar energy autotracker, difference along with the deviation angle of daylight, change the deflection angle of lens, thereby realize that solar cell maximization luminous energy absorbs.
With reference to Fig. 2 and Fig. 3: solar panel 6 of the present invention adopts crystal silicon solar cell sheets 8 and anti-hot spot circuit 9 to form solar energy crystal silicon cell chip arrays, anti-hot spot circuit 8 adopts parallel way to be connected with crystal silicon solar cell sheet 9, anti-hot spot circuit 8 also can adopt series system to be connected with crystal silicon solar cell sheet 9, the solar panel 6 that uses is the solar module technology of integrated anti-" hot spot " circuit, the solar energy crystal silicon cell sheet of circuit thermal conductance, connect to form the solar battery sheet array by many groups crystal silicon cell sheet and thermal conductance circuit, carry out heat diffusion and crystal silicon cell discharging function; Adopt the power circuit integrated technology will prevent that " hot spot " circuit is integrated near the solar energy crystal silicon cell sheet, anti-" hot spot " circuit is that special thickness is the integrated circuit of 0.5mm, adopt constant temperature welding polymerization methods with the silvery sealing wire integrated circuit and battery sheet to be coupled together, this kind design can be satisfied the requirement of industrialized mass production; The solar battery technology of described integrated anti-" hot spot " circuit, adopt the power circuit integrated technology will prevent that " hot spot " circuit is integrated near every small pieces battery sheet, not only can avoid in the series circuit individual solar cells because of being blocked or other reason causes daylighting inequality on the variant solar cell piece, forming " hot spot " damages, simultaneously, avoided whole battery group because of daylighting inequality cause the being blocked power loss of battery discharge, the user do not need to consider connection in series-parallel yet.
