Description

technical field [0001] The present invention relates to the field of power generation equipment, in particular, to a solar-thermal integrated power generation device. Background technique [0002] Power generation refers to the production process of converting water energy, thermal energy of fossil fuels (coal, oil, natural gas), nuclear energy, etc. into electrical energy by using power generation power devices. Most of the DC power generation generates electricity in an electrochemical manner, which is generally called a battery, and is mainly used for low-power applications. The main forms of power generation are hydropower, thermal power and nuclear power. [0003] Against the background of increasingly severe global warming and carbon dioxide emissions, countries around the world are striving to promote the use of clean power sources and the development of renewable energy. New energy must meet two conditions at the same time: one is that it is rich and will not be ex...

Problems solved by technology

[0004] Obtaining electricity from solar energy needs to be realized through photoelectric conversion of solar cells. For current solar panels, the current industrialized solar cells are basically divided into three categories: monocrystalline silicon, polycrystalline silicon and amorphous silicon. The solar energy conversion efficiency of industrialized products is respectively It is about 20%, about 17%, about 10%; the rest of the capacity is lost in the form of heat energy, so that the utilization of solar energy is extremely low
