Description
Technical field
The invention provides a kind of solar-energy light-focusing battery unit, it is the solar-energy light-focusing battery unit that is used for concentrating solar power generation system.
Background technology
Serious day by day along with fossil energy shortage and environmental pollution, the utilization of regenerative resource causes the attention of national governments.Solar energy is subjected to special concern with the characteristic of its inexhaustible, nexhaustible and zero pollution.The Application of Solar Energy exist is at the obstacle that can't go beyond, and it is too low that arrives ground solar energy density exactly, and its peak value is only about one kilowatt every square metre.Utilize condenser can improve solar energy density effectively.By concentrator larger area sunlight is focused at and forms " focal spot " in the small range, and solar cell placed on this " focal spot " or " burnt band ", to increase light intensity, overcome the low defective of solar radiation energy-flux density, thereby obtain more electric energy output.As seen concentrator solar cell is to improve conversion efficiency, reduces a kind of effective measures of solar cell total cost.
Because the relative ground of the sun move, so concentrating solar battery system must follow the tracks of the sun, all drops on the battery sheet with the hot spot that guarantees from morning to night to reach after the focusing throughout the year.Therefore optimize structural design of concentrator and preparation method thereof, can lower requirement, thereby reduce the cost of manufacture of concentrator solar cell, help applying of concentrator solar cell tracker accuracy.
Yet, this class optically focused photovoltaic cell to the day tracking means, a huge system that but is complex structure, involves great expense, especially surrounding enviroment are comparatively abominable or run into special weather, be difficult to guarantee that all the time condenser mirror and battery are over against the sun, thereby can not make full use of solar energy, the power output instability and the conversion efficiency of solar cell are reduced significantly.
Summary of the invention
The objective of the invention is to, a kind of solar-energy light-focusing battery unit is provided, this solar-energy light-focusing battery unit can be formed photovoltaic concentrator module by the mode of series and parallel, outside the advantage of inheriting tradition concentrator solar cell, also reduced requirement to the tracking means precision, simplified the manufacture craft of photovoltaic concentrator module, be fit to producing in batches.This solar-energy light-focusing battery unit has greatly improved the photoelectric conversion efficiency of solar energy utilization ratio and solar cell, and has guaranteed the stability of power output.
The objective of the invention is to realize by following technical scheme:
A kind of solar-energy light-focusing battery unit of the present invention is characterized in that, comprising:
One fin;
One base, this base be positioned at fin above;

One Fresnel Lenses, this Fresnel Lenses is positioned at above the bigger diameter end of light conducting cylinder, and is attached thereto.
Wherein said base and fin are structure as a whole, or divide body structure.
Wherein said battery chip is the unijunction solar cell, or multijunction solar cell.
Wherein the connected mode of light conducting cylinder and base is for pegging graft.
Wherein the connected mode of the bigger diameter end of Fresnel Lenses and light conducting cylinder is for pegging graft.
Solar-energy light-focusing battery unit provided by the invention, it is to be made of Fresnel Lenses, light conducting cylinder, battery chip, base and fin, light conducting cylinder wherein is taper, inwall is a specular reflector, after sun light beam focuses on by collector lens, in case depart from battery surface, then can be by the repeatedly reflection of speculum, finally make ray cast on the solar cell upper surface, thereby realize the forward irradiation of sunlight, improve the photoelectric conversion efficiency of solar energy utilization ratio and solar cell greatly, and guaranteed the stability of power output.
Use this solar-energy light-focusing battery unit, it can form photovoltaic concentrator module by the mode of series and parallel, outside the advantage of inheriting tradition concentrator solar cell (efficient, stable, the life-span is long, anti-radiation performance good), also reduced requirement to the tracking means precision, simplified the manufacture craft of photovoltaic concentrator module, be fit to producing in batches.Thereby reduce the cost of system, help the practical application of concentrating solar power generation system.
