Description
technical field [0001] The invention belongs to the technical field of solar power generation, and in particular relates to a photovoltaic and photothermal coupling power generation system. Background technique [0002] With the increasing shortage of traditional energy sources and the increasing pressure on environmental protection, new energy sources have received more attention. Among them, solar energy, as one of the most widely used new energy sources with high technological maturity, has received widespread attention. [0003] Existing photovoltaic and photothermal power generation technologies are relatively independent, but there are differences in the operating range and temperature level of the two, and they can be used in cascades. However, traditional photovoltaic cells will generate a lot of heat during the working process, and if the temperature cannot be cooled in time, it will affect its working stability; due to the heat dissipation requirements of tradition...
