Reflective light-gathering solar photovoltaic electricity-generating component

Abstract

The invention discloses a reflective light-gathering solar photovoltaic electricity-generating component, which comprises a primary reflector, a secondary reflector, a transparent protective cover plate, photovoltaic cells, a conductive connecting line, a radiator base plate and a frame. The primary reflector thereon is provided with more than one group of trough parabolic reflecting mirror surfaces, one trough parabolic reflecting mirror surface is correspondingly provided with a secondary reflector, and each secondary reflector thereon is provided with a strip curved reflecting mirror surface, and the bottom of each trough parabolic reflecting mirror surface is corresponding to a photovoltaic cell. The strip curved reflecting mirror surfaces and the trough parabolic reflecting mirror surfaces are matched and used for forming light-gathering illumination with the same radiation strength on the surfaces of the photovoltaic cells, so as to improve the photovoltaic conversion efficiency of ordinary photovoltaic cells of unit area, even obtain higher fold of light-gathering ratio, and reach the purpose of using less photovoltaic cells under the condition of given power, so that the total cost of a photovoltaic electricity-generating system is reduced.

Description

technical field [0001] The invention relates to a structure of a photoelectric conversion module of a concentrating photovoltaic system, which belongs to the technical field of solar energy utilization, in particular to a reflective concentrating solar photovoltaic power generation component. Background technique [0002] The development of new energy and renewable clean energy is a common issue faced by the whole world. In the development and utilization of new energy, photovoltaic power generation has attracted much attention. At present, photovoltaic power generation mainly adopts ordinary flat-panel photovoltaic power generation system. Ordinary flat-panel photovoltaic power generation systems directly place flat-panel solar cell components towards low-latitude regions (at a certain angle to the ground), and form solar photovoltaic arrays in series and parallel to achieve the purpose of using solar power to generate electricity. In an ordinary flat-panel photovoltaic po...

Problems solved by technology

However, from a technical point of view, the uniformity of the concentrated light intensity of the Fresnel lens on a specific surface is relatively poor.

From an industrial point of view, compared to reflective methods, the cost of special lenses is still higher than the cost of reflective mirrors with high reflectivity
