Description
Technical field
The present invention relates to a kind of structure of concentration photovoltaic system photoelectric conversion module, belong to technical field of solar utilization technique, particularly a kind of reflective light-gathering solar photovoltaic electricity-generating component.
Background technology
Tap a new source of energy and renewable and clean energy resource be the common issue that the whole world faces, new energy development with utilize in the mode, photovoltaic generation attracts tremendous attention.At present, photovoltaic generation mainly adopts the ordinary flat photovoltaic generating system.The ordinary flat photovoltaic generating system is directly placed (angled with ground) with dull and stereotyped solar module towards low latitudes, reaches the purpose of using solar power generation thereby form the solar energy photovoltaic array in series-parallel mode.In the ordinary flat photovoltaic generating system, the cost of solar cell accounts for significant proportion in the system synthesis basis, because the price comparison of solar cell is high, thereby has directly caused the cost of system too high.At present, the conversion efficiency of the photovoltaic cell of use is low, cost is high, is the not one of the main reasons of wide popularization and application on market of photovoltaic generation.
Photovoltaic cell can be worked under quite high light intensity condition, uses photovoltaic cell to carry out opto-electronic conversion under the optically focused condition, is one of effective way that reduces cost for solar power generation.Adopt concentration photovoltaic system, can reduce the required cell area of given power, partly replace expensive solar cell with comparatively cheap concentrator.In this system, the total cost of solar cell can significantly reduce, and the total cost of electricity generation system also descends thereupon.
If concentrator cell is worked under the sun light intensity condition of 300 times or higher multiple, and can reach quite high photoelectric conversion efficiency (25%-36%).But, the photovoltaic cell of this high power concentrator needs expensive semi-conducting material (indium gallium or purification high purity silicon etc.), and processing technology is also very complicated, when using under the optically focused condition, it is very high that the temperature of photovoltaic cell can become, and needs cooling technology harsher and that efficient is very high.Especially under the silicon materials photovoltaic cell, constant situation that photovoltaic battery temperature raises in, can cause open circuit voltage to reduce at intensity of sunshine, reduced rate is-0.4%/K～-0.5%/K, thus the power output of silicon materials photovoltaic cell is also reduced.Cooling device can increase the cost of photovoltaic generating system, is not suitable for general occasion and promotes the use of.If concentrator cell is worked under with interior sun light intensity condition at 3～10 times, can save 66～90% solar cell.In the temperature that solar cell produces, can carry out efficiently radiates heat by the mode of using conventional fin.Therefore, this concentrator cell has certain advantage aspect the reduction cost of electricity-generating.
Be called in the patent document of " making the solar-energy photovoltaic cell generating device of realizing several times optically focused with light funnel bounce technique on earth " in disclosed patent No. ZL200510200596.0, name, this device can be realized 3～7 times optically focused ratio in theory, yet under reality, consider factors such as size and reflection loss, can only reach 3.5～4.3 times optically focused ratio.If reach described 7 times of optically focused ratios, the size of its reflecting surface needs endless just can accomplish, this obviously is impracticable in production application.That is to say that this structure can not realize about 10 times in actual production, and realize size change between the higher multiple, to adapt to different temperature and photoenvironment.This device need carry out two-dimensional tracking just can carry out operate as normal, promptly need follow the tracks of at solar azimuth and elevation angle both direction, and system complex degree and cost that this has increased photovoltaic generation undoubtedly greatly are unfavorable for promoting the use of.
Transmission optically focused also is an approach that realizes higher multiple, and it also is very noticeable reducing the cost that gets off owing to a large amount of productions of Fresnel Lenses.Yet from the angle of technology, the uniformity of the optically focused light intensity of Fresnel Lenses on certain surface is less better relatively.From industrialized viewpoint of measures, than bounce technique, the cost of special lens still is higher than the cost with high reflectivity mirror face.

The focal line of flute profile parabolic mirror face 11 is by the L point, and strip camber reflection minute surface 10 is arranged on the outside of secondary reflecting body 2.The limit, outer of strip camber reflection minute surface 10 is parallel with the focal line of flute profile parabolic mirror face 11, in xy plane of symmetry first quartile with the xy Plane intersects in the M point, the length of LM is identical with the width of photovoltaic cell 6 in xy plane of symmetry first quartile, that is:
LM＝r (2)
The coordinate of M point in the xy plane be (r, R/2).
According to the knowledge of parabolic reflector as can be known, light A point on flute profile parabolic mirror face 11 by the inboard incident of A point carries out primary event, the M point carries out the reflection second time on strip camber reflection minute surface 10 again, be incident upon again on the photovoltaic cell 6 at the axial outermost G (r of x, 0) point, wherein ACB section curve is the intersection of flute profile parabolic mirror face 11 on the xy plane of symmetry, is parabola:
In one section.(x wherein
2, y
2) be any point coordinates on this parabola.Behind the B point reflection, carry out reflexing to the second time O point by F point on the strip camber reflection minute surface 10 by the light of M point outside incident again, wherein curve M DF is the intersection of strip camber reflection minute surface 10 on the xy plane of symmetry.
When n got different numerical value, flute profile parabolic mirror face 11 had different width R.Therefore, when different light concentrating times require, flute profile parabolic mirror face 11 that can corresponding different openings width 2R.
In the AM interval, any incident ray NC C (x on flute profile parabolic mirror face that is parallel to the y axle
2, y
2) behind the point reflection, again on strip camber reflection minute surface 10 D (x, reflection second time y) fall within photovoltaic cell 6 surfaces and go up E (x
