Description
Technical field
The utility model relates to a kind of photovoltaic generation parts, is specifically related to a kind of concentration photovoltaic receiver with the secondary optics element, belongs to the solar energy generation technology field.
Background technology
Along with day by day exhausted, the serious consequence that nuclear radiation brings of global energy, the enhancing of human environmental consciousness; And have plurality of advantages such as cleaning, safety, noiselessness, electromagnetic-radiation-free, simple in structure, easy mounting; Solar energy power generating has become a kind of new forms of energy of great exploitation potential for its; But because too high cost; Also fail at present fully to come into the market, so solar photovoltaic technology has become one of important topic of countries in the world research at present, and the emphasis of research is how to improve the conversion efficiency of solar cell and how to reduce the photovoltaic generation cost.Using one of valid approach at present is to adopt the condensation photovoltaic battery, greatly reduces the usable floor area of battery, realizes photovoltaic power generation technology with comparatively cheap concentrator.
The current transmission-type concentrator that generally adopts is with low cost with it, be prone to produce in enormous quantities, convenient plurality of advantages such as integrated, at home and abroad is widely used.The secondary optics element all directly adopts organic silica gel to bond to the mode on the concentration photovoltaic receiver at present; The lower port of secondary optics element is far longer than condensation photovoltaic battery sheet; Be difficult in the course of processing will be through the high power concentrator of a concentrator and the hot spot that forms converge to fully on the effective area of condensation photovoltaic battery sheet; Organic silica gel holds and can't stand that high power concentrator converges the high temperature that produces simultaneously; Will reduce the photoelectric conversion efficiency of solar cell and the useful life that reduces product so greatly, therefore be badly in need of the structural design and the fixed form of concentrator are improved accordingly, to satisfy the high power concentrator instructions for use.
Summary of the invention
The purpose of the utility model is the deficiency that overcomes prior art, and a kind of concentration photovoltaic receiver with the secondary optics element is provided.
In order to realize above-mentioned technical purpose; The technical scheme that the utility model is taked is: a kind of concentration photovoltaic receiver with the secondary optics element; It is characterized in that it comprises secondary optics element, fixed support and concentration photovoltaic receiver, said secondary optics element is a tapered optical element; Comprise the side of upper and lower two end faces and four isosceles trapezoids, the area of upper surface is greater than the area of lower surface; Said secondary optics element and fixed support are integral through organic silica gel is critically bonding.
The lower surface shape of said secondary optics element is consistent with size with the significant surface shape of condensation photovoltaic battery with size.
The upper surface shape of said fixed support port shape and secondary optics element is the same, and its size is less than the upper surface size of secondary optics element; Said support bracket fastened inwall must be that smooth outer wall shape smooth and inner wall shape and secondary optics element is consistent; Said fixed support port is symmetrically arranged with the fixed installation pin.
Said fixed installation pin is provided with the fixed installation hole, and said fixed installation pin is outer bending shape, and said fixed installation pin is fixed on the concentrating photovoltaic assembly box plate.
Said organic silica gel adopts the organic silica gel with the aging function of antiultraviolet irradiation and anti-high temperature.
Substantive distinguishing features and obvious improvement that the utility model technical scheme is outstanding are mainly reflected in: 1. the planform of secondary optics element is simple, is one six cone that face all is the plane fully; 2. traditional little a lot of of the volume ratio of secondary optics element, in light weight, consumptive material is few; 3. the fixed form of secondary optics element is simple, directly is fixed on the fixed support; 4. the aligning accuracy of secondary optics element is high, and the lower port shape of secondary optics element is consistent with the significant surface shape of condensation photovoltaic battery sheet, can guarantee that the light that converges all gathers on the effective area of condensation photovoltaic battery sheet; 5. fixed support also has the part heat transmission function, can will lack the radiator that is delivered on the base plate of portion of hot get on.
