Description
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.
