Abstract

The invention relates to a solar concentration and frequency division photovoltaic photo-thermal comprehensive utilization device which comprises a concentrator, photovoltaic assemblies, spectral frequency dividers, a thermal receiver and a secondary reflector. The concentrator comprises a plurality of plane glass mirrors and a concentrator frame, the plane glass mirrors are arranged obliquely, and the concentrator frame is arranged at an inclination angle theta2; the plane glass mirrors are obliquely focused on surfaces of the photovoltaic assemblies mounted above the concentrator frame; the photovoltaic assemblies are mounted at inclination angles theta1; the photovoltaic assemblies and the thermal receiver are respectively arranged on upper sides and lower sides of the spectral frequency dividers; and the secondary reflector is arranged below the thermal receiver. The solar concentration and frequency division photovoltaic photo-thermal comprehensive utilization device has the advantages that problems of overheating of the surface of a concentrator solar cell and uneven distribution of energy flow on the surface of the concentrator solar cell are solved, and the conversion efficiency of a cell and the energy efficiency of a thermal utilization portion are improved.

Description

technical field [0001] The invention relates to the technical field of solar energy utilization and new energy development, in particular to a device for comprehensive utilization of solar energy concentrating and frequency dividing photovoltaic light and heat. Background technique [0002] Solar energy is an important renewable energy, and its efficient utilization has become an important topic of research. Traditionally, solar energy utilization mainly includes photovoltaic conversion and photothermal conversion. Both of these methods are subject to low solar energy flux density (about 1000W / m 2 ). Concentrating light is used to increase the radiant energy flow density of solar energy. When using light and heat, it can increase the temperature of heat collection and improve the effective energy efficiency; when converting photovoltaics, it can reduce the amount of photovoltaic cells and reduce costs. At the same time, concentrator cells have a higher photoelectric conv...
