Embodiment
as shown in Figure 1, the present invention includes housing 3, be connected to the fin 1 and the collector lens 4 that is connected to housing 3 tops of housing 3 bottoms, the place, focal position that the top of described fin 1 is positioned at described collector lens 4 incidents is equipped with photovoltaic chip 5, be provided with insulating heat-conductive plate 11 between described photovoltaic chip 5 and fin 1, fin 1 top that is positioned at described photovoltaic chip 5 both sides is equipped with for output electric weight conductive plate 6, be provided with insulation board 10 between described conductive plate 6 and fin 1, described conductive plate 6 is electrically connected to photovoltaic chip 5 by wire 12, described photovoltaic chip 5 tops are provided with for the secondary optical system that improves light gathering efficiency.
As shown in Figure 1, in the present embodiment, described secondary optical system comprises the condensing glass 9 of inverted round stage shape and is arranged on condensing glass 9 tops and is coated with the secondary condensation lens 2 of optical thin film.Described optical thin film comprises the anti-reflection film 7 that is plated in secondary condensation lens 2 centre positions places and is plated in the reflectance coating 8 at secondary condensation lens 2 marginal position places.Described collector lens 4 is bonded in the top of housing 3 by optical cement.Described photovoltaic chip 5 is the gallium arsenide solar cell chip.Described collector lens 4 is Fresnel Lenses.
operation principle of the present invention and the course of work are: the sunlight of non-perpendicular irradiation by collector lens 4 optically focused after, further light is proofreaied and correct optically focused by secondary optical system again, light can not deflected because of the error of tracking means, continue to be radiated on photovoltaic chip 5, then photovoltaic chip 5 becomes luminous energy into electric energy, derived by the conductive plate 6 that is connected with photovoltaic chip 5 by wire 12, the photovoltaic chip is equipped with fin 1 by insulating heat-conductive plate 11 5 times, fin 1 can be dispelled the heat fully, the steady operation that keeps photovoltaic chip 5.2 centre positions places are coated with anti-reflection film due to the secondary condensation lens, and secondary condensation lens 2 marginal position places are coated with reflectance coating, have further improved the efficient of optically focused, have realized the correction again of light.
The present invention is by itself starting with from the solar concentrating photovoltaic power generation assembly, method by optics makes the sun light beam that deflects a little continue to correct, shine on the solar concentrating photovoltaic power generation assembly, has higher optoelectronic transformation efficiency, can make up the coarse problem of sun tracker, can reduce the photovoltaic generation cost, improve generating efficiency, can be widely used in all kinds of solar photovoltaic generation systems.
The above; it is only preferred embodiment of the present invention; be not that the present invention is imposed any restrictions, every any simple modification, change and equivalent structure of above embodiment being done according to the technology of the present invention essence changes, and all still belongs in the protection range of technical solution of the present invention.
