Description

technical field [0001] The invention belongs to the technical field of comprehensive utilization of solar photovoltaic light and heat, and specifically relates to the application of direct combination of photovoltaic light heat, semiconductor thermoelectric sheets and water tanks. Background technique [0002] The solar photovoltaic photothermal integrated technology system can realize the dual functions of power supply and hot water supply. Limited by the performance of photovoltaic cells, the photoelectric conversion efficiency of the system is low. At this stage, air and water cooling methods are mostly used to reduce the temperature of photovoltaic cells to improve their photoelectric efficiency, but the system only uses the energy of visible light to generate electricity by photoelectric effect. The use of multi-spectral energy power generation technology needs to be extended research. Contents of the invention [0003] Aiming at the problems of low photoelectric ef...
