Problems solved by technology

The CPV system requires sunlight to be incident perpendicular to the concentrating module, so that the converging light spot can accurately fall on the battery chip with a very small area. Active tracking system is used, which is more complicated

Abstract

The invention discloses an ultra-thin solar condenser. The ultra-thin solar condenser comprises a glass panel, wherein a reflector array formed by a plurality of mini-type reflectors is arranged on the upper side of the bottom of the glass panel, a secondary reflector which can carry out light on secondary reflection is arranged at the center position of the upper side of the bottom of the glass panel, a solar battery is arranged at the center position of the lower side of the bottom of the glass panel, a Fresnel lens is arranged on the upper side of the glass panel, and a transparent plastic sheet is arranged on the upper side of the Fresnel lens. The ultra-thin solar condenser has the adventures of being reasonable in design, simple in structure, good in spotlight effect and wide in range of application.

Description

technical field [0001] The invention relates to a concentrator, in particular to an ultra-thin solar concentrator for solar power generation. Background technique [0002] In recent years, the rapid development of renewable energy technologies based on solar energy and wind energy, especially based on solar power generation technology, has provided new broad prospects for solving energy problems in the future. In order to further reduce costs, the research on solar concentrating systems has been intensified. At present, concentrating solar power generation technologies are mainly embodied in CPV concentrating photovoltaics and CST concentrating solar thermal. [0003] Concentrating photovoltaic (CPV) is a representative of new solar power generation technology. Because of its high photoelectric conversion efficiency, CPV occupies a smaller area than concentrated solar thermal power generation, and has huge room for development in the future. It can be used to build large-sca...
