Description

Technical field: [0001] The name of the invention is a solar energy comprehensive utilization system integrating photothermal hybrid power generation and heat utilization, which belongs to the field of solar energy comprehensive utilization engineering. Background technique: [0002] Among the utilization methods of solar energy, solar photovoltaic power generation is currently one of the more common and more researched methods. However, the efficiency of solar photovoltaic power generation is low, generally only 10-20%. Therefore, in the process of solar photovoltaic conversion, on the one hand, it will cause a lot of solar thermal energy waste, and at the same time, the thermal energy that is not converted into electrical energy will also cause the temperature of solar photovoltaic cells to rise. high. According to research, the conversion efficiency of solar photovoltaic cells decreases with increasing temperature, and the waste heat generated by solar photovoltaic cells duri...
