Concentrating photovoltaic receiver with secondary optical element

Abstract

The invention relates to a concentrating photovoltaic receiver with a secondary optical element and belongs to the technical field of solar power generation. The concentrating photovoltaic receiver with the secondary optical element comprises a secondary optical element, a fixed support and a concentrating photovoltaic receiver, wherein the secondary optical element and the fixed support are precisely and integrally bonded together through a silicone adhesive; fixed mounting legs are symmetrically arranged on the upper opening of the fixed support; fixed mounting holes are formed in the fixed mounting legs; the fixed mounting legs are fixed on the floor of a concentrating photovoltaic module box. The concentrating photovoltaic receiver with the secondary optical element is characterized in that the secondary optical element is simple in structure, small in volume, low in weight and low in material consumption, the fixing manner of the secondary optical element is simple and high in alignment accuracy so as to guarantee that the collected light is all concentrated on the effective area of a concentrating photovoltaic battery piece, and therefore, the conversion efficiency of a solar battery is improved.

Description

technical field [0001] The invention relates to a photovoltaic power generation component, in particular to a concentrating photovoltaic receiver with a secondary optical element, which belongs to the technical field of solar power generation. Background technique [0002] With the depletion of global energy, the serious consequences of nuclear radiation, and the enhancement of human environmental protection awareness, as well as many advantages such as cleanliness, safety, no noise, no electromagnetic radiation, simple structure, and easy installation, solar photovoltaic power generation has become a A new energy source with great development potential, but due to the high cost, it has not yet fully entered the market, so solar photovoltaic power generation technology has become one of the important research topics in countries all over the world, and the focus of the research is how to improve solar cells. conversion efficiency and how to reduce the cost of photovoltai...

AI Technical Summary

Problems solved by technology

At present, the secondary optical components are directly bonded to the concentrator photovoltaic receiver with silicone. The lower port of the secondary optical component is much larger than the concentrator photovoltaic cells, so it is difficult to pass through the primary concentrator during processing. The light spot formed by the high concentration of light is completely concentrated on the effective area of ​​the concentrated photovoltaic cell, and the organic silica gel cannot withstand the high temperature generated by the high concentration of light, which will greatly reduce the photoelectric conversion efficiency of the solar cell and reduce the cost of the product. Therefore, it is urgent to improve the structural design and fixing method of the concentrator to meet the use requirements
