Description
Technical field
The utility model relates to the technical field of solar power generation, refers in particular to a kind of concentration photovoltaic receiver.
Background technology
Along with the continuous aggravation of the day by day exhausted of traditional energy and environmental pollution, developing reproducible clean energy resource has become the common issue that the whole world faces.In various forms of new energy development, the photovoltaic technology utilizing solar energy to generate electricity gets most of the attention, but photovoltaic generation is very low as the part proportion of whole society energy resource structure, causes the main cause of this situation to be that the cost of photovoltaic generation is too high.So reducing cost of electricity-generating is the top priority that current photovoltaic technology faces, one of effective way adopts concentrator solar cell, carrys out part replace expensive solar cell, so-called light-focusing type photovoltaic technology that Here it is by comparatively cheap Fresnel lens concentrator.
The high power concentrating photovoltaic module of light-focusing type photovoltaic technology is adopted all to need to be equipped with high-precision dual-axis tracking system.But the tracking error due to dual-axis tracking system can reduce the light energy that concentrating solar battery receives greatly.Meanwhile, because the hot spot-effect of Fresnel lens high power focal beam spot, concentrating solar battery are to the restriction of the dependence of spot intensity distributing homogeneity and system installation accuracy, the conversion efficiency of high power light concentrating photovoltaic system can be very limited.Based on the hot spot effect of Fresnel lens focus hot spot in current condensation photovoltaic technology, focal beam spot is difficult to converge on the effective area of shining light of solar cell completely, and fixedly need particular stent due to some current secondary condensation original papers, bring certain difficulty to production and add cost, therefore to the design of secondary condensation original paper and the improvement of fixed form particularly important.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of rational in infrastructure reliable, assembling is fast, cost is low, the concentration photovoltaic receiver of superior performance.
For achieving the above object, technical scheme provided by the utility model is: a kind of concentration photovoltaic receiver, include the concentration photovoltaic receiver body based on dense matrix, the solar cell of described concentration photovoltaic receiver body is bonded with secondary microprism, wherein, the exit end of described secondary microprism is bonded on effective sensitive surface of solar cell, and its incidence end and exit end are positive rectangular pyramid, and the size of its incidence end is greater than its exit end.
The outgoing end surface shape of described secondary microprism and the shape of solar cell suitable, its size is less than the effective area of shining light of solar cell.
The incident end face of described secondary microprism is smooth and parallel with outgoing end face, and the both ends of the surface line of centres is perpendicular to these both ends of the surface.
The outgoing end face center of described secondary microprism and effective sensitive surface center superposition of solar cell.
Each surface of described secondary microprism maintains evenness.
Described secondary microprism is bonded on solar cell by the organic silica gel of light-permeable.
The refractive index of described organic silica gel is more than or equal to the refractive index of secondary microprism.
Compared with prior art, tool has the following advantages and beneficial effect the utility model:
The volume of the secondary microprism 1, adopted is little, lightweight, structure simple, is convenient to processing like this, can reduces costs;
2, the fixed form of secondary microprism is simple, only bonding by organic silica gel, can realize automation batch and install;
3, the outgoing end face of secondary microprism is dimensioned slightly smaller than the effective area of shining light of solar cell, like this while all converged light of guarantee gather solar cell effective area of shining light, can realize industrial automated production in enormous quantities;
4, secondary microprism add the environmental suitability effectively increasing concentration photovoltaic receiver, thus ensure solar cell work efficiently for a long time;
5, the utility model assembling is fast, enforcement is easy, production cost is lower, and be suitable for industrial production in enormous quantities, applied range, market prospects are good.

Embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail.
As shown in Figure 1 to Figure 3, concentration photovoltaic receiver described in the present embodiment, include the concentration photovoltaic receiver body 1 based on dense matrix, wherein, organic silica gel 3 by light-permeable on the solar cell 101 of described concentration photovoltaic receiver body 1 is bonded with secondary microprism 2, and the refractive index of described organic silica gel 3 is more than or equal to the refractive index of secondary microprism 2; The exit end of described secondary microprism 2 is bonded on effective sensitive surface of solar cell 101, and the shape of its outgoing end surface shape and solar cell 101 is suitable, be dimensioned slightly smaller than the effective area of shining light of solar cell 101, meanwhile, effective sensitive surface center superposition of its outgoing end face center and solar cell 101; In addition, incidence end and the exit end of described secondary microprism 2 are positive rectangular pyramid, the size of its incidence end is greater than its exit end, its incident end face is smooth and parallel with outgoing end face, and the both ends of the surface line of centres is perpendicular to these both ends of the surface, and each surface of described secondary microprism 2 must maintain certain evenness, so just can ensure that all converged light gather on effective sensitive surface of solar cell 101.
In sum, after the above scheme of employing, not only volume is little, lightweight, fixed form is simple for the secondary microprism that the utility model adopts, and automation can be realized under all converged light are gathered in the prerequisite of solar cell effective area of shining light and install in enormous quantities, and solve the adaptability of condensation photovoltaic to ambient temperature, thus ensure that solar cell works for a long time efficiently.In a word, the high efficiency of solar cell and the realization of industrialization ensure that and be worthy to be popularized the market prospects that this concentration photovoltaic receiver is wide.
