Description

technical field [0001] The invention relates to a heat-collecting solar photothermoelectric system, which converts solar light energy and thermal energy into electric energy, thermal energy and other energy sources required for production and life. Background technique [0002] At present, many countries are formulating medium and long-term solar energy development plans, preparing to develop solar energy on a large scale in the 21st century, and some developed countries have begun to implement "solar energy projects" to integrate solar energy utilization with buildings. In the middle of the 21st century, nuclear energy, solar energy, water energy, and wind energy will become the pillars of world energy. As far as solar energy is concerned, the energy of solar energy shining on the earth's surface every 15 minutes is enough for human beings to use for a whole year. In two-thirds of China, the daily radiation can reach 1000W / m 2 , solar energy resources are very rich. [00...

AI Technical Summary

Problems solved by technology

At present, solar photovoltaic power generation devices, which are widely used, have many disadvantages, such as: high investment cost, not easy to popularize; and the initial preparation of silicon is a high-pollution, high-energy-consuming industry, which has a serious impact on the environment

The on-grid electricity price of solar power generation is about 3.5-4.5 yuan / kWh, which is more than 10 times the on-grid electricity price of ordinary thermal power generation. Such a high cost is difficult to popularize at present, and its market share is not high.
