Description
Technical field
The present invention relates to a kind of photovoltaic generation parts, be specifically related to a kind of concentration photovoltaic receiver with secondary optics element, belong to solar energy generation technology field.
Background technology
Along with the day by day exhaustion of global energy, the enhancing of the serious consequence that nuclear radiation brings and mankind's environmental consciousness, and have clean, safety, noiselessness, electromagnetic-radiation-free, simple in structure, the plurality of advantages such as easy installation, solar energy power generating has become a kind of new forms of energy of great exploitation potential for its, but due to too high cost, also fail at present fully to come into the market, so solar photovoltaic technology has now become one of important topic of countries in the world research, and the emphasis of research is how to improve the conversion efficiency of solar cell and how to reduce photovoltaic generation cost.At present application one of the most effective approach is to adopt condensation photovoltaic battery, greatly reduce the usable floor area of battery, realize photovoltaic power generation technology with comparatively cheap concentrator, current generally adopt transmission-type concentrator with its with low cost, easy production in enormous quantities, facilitate the plurality of advantages such as integrated, be at home and abroad widely used.Secondary optics element all directly adopts organic silica gel to bond to the mode on concentration photovoltaic receiver at present, the lower port of secondary optics element is far longer than concentrating photovoltaic cell slice, the hot spot that is difficult in the course of processing, the high power concentrator through a concentrator be formed converges on the effective area of concentrating photovoltaic cell slice completely, organic silica gel holds and can't stand that high power concentrator converges the high temperature producing simultaneously, will greatly reduce like this photoelectric conversion efficiency of solar cell and reduce the useful life of product, therefore structural design and the fixed form be badly in need of concentrator are improved accordingly, to meet instructions for use.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of concentration photovoltaic receiver with secondary optics element is provided.
In order to realize above-mentioned technical purpose, the technical scheme that the present invention takes is: a kind of concentration photovoltaic receiver with secondary optics element, it is characterized in that, it comprises secondary optics element, fixed support, concentration photovoltaic receiver, fixed installation pin and fixed installation hole, described 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.
