A primary reflector, an arc spectrum frequency divider, a photovoltaic module, a secondary reflector and a heat collector are installed on the support. The primary reflector is used for reflecting sunlight. The arc spectrum frequency divider is used for receiving sunlight reflected by the primary reflector and conducting transmission and reflection. The photovoltaic module is used for receiving sunlight transmitted by the arc spectrum frequency divider for photovoltaic power generation. The secondary reflector is used for reflecting sunlight reflected by the arc spectrum frequency divider again. The heat collector is used for receiving sunlight reflected by the arc spectrum frequency divider and receiving sunlight reflected by the secondary reflector for photo-thermal power generation. Wave bands capable of being used by the photovoltaic module can transmit the photovoltaic module for photovoltaic power generation, wave bands not facilitating photovoltaic power generation of the photovoltaic module are reflected to the heat collector for photo-thermal power generation, the energy flux density of the photovoltaic module is large, and the power generation capacity of the photovoltaic module is high.

Description

technical field [0001] The invention belongs to the field of solar power generation devices, and more specifically relates to a high-efficiency concentrating power generation device based on solar gradient utilization. Background technique [0002] As an important form of new energy development and utilization, solar energy has broad application prospects. The traditional solar energy utilization is mainly photothermal utilization and photovoltaic power generation, but due to the low energy flux density of solar energy, the utilization efficiency of these two methods is not high. Therefore, how to utilize solar energy efficiently and at low cost has become an urgent problem to be solved in solar energy applications. At present, solar thermal power generation uses concentrating methods to heat the working fluid in the collector, and then sends the obtained higher temperature working fluid to the steam turbine for power generation; for photovoltaic power generation, the use o...
