People's use of solar energy includes: photothermal use, power generation use, photochemical use, and fuel use.
1. Photothermal use
The basic principle of photothermal use is to collect energy from solar radiation and convert it into thermal energy through interaction with matter for use. The most commonly used solar energy harvesting devices at present mainly include flat plate collectors, vacuum tube collectors, ceramic solar collectors and focused collectors.
2. Use of power generation
Use of power generation, large-scale use of solar energy in the future will be used to generate electricity. And there are many ways to use solar energy to generate electricity.
3. Usephotochemical conversion
Photochemical utilization is a photochemical conversion method that uses energy from solar radiation to directly decompose water to produce hydrogen. This includes photosynthesis, photoelectrochemistry, photosensitive chemistry and photodecomposition reactions.
4. Use of fuel
Since June 2011, the European Union has engaged in the development and production of "solar" fuel using high temperature energy provided by the sun's rays. and using water and carbon dioxide as raw materials.
