What is the principle of photovoltaic power generation?

The principle of photovoltaic power generation mainly uses solar cells to directly convert sunlight into electric energy to generate electricity. The original photovoltaic effect principle is used. When exposed to solar light, the independent photovoltaic power generation system can convert solar energy into electric energy in daytime, and photovoltaic power generation technology is gradually being applied all over the world.

Photovoltaic power generation system is composed of solar photovoltaic power generation, photochemical power generation, photo-induced power generation and photobiological power generation. Photovoltaic power generation is the most common one in life. Compared with thermal power generation and nuclear power generation, solar cells will not cause environmental pollution, and are suitable for various load machines, with long service life and wide working range.

Photovoltaic cell is the core part of solar photovoltaic power generation system, which can improve the photoelectric conversion efficiency and reduce the production cost. In case of problems, it can also be adjusted by connecting the power grid to form photovoltaic response. Many technologies related to photovoltaic power generation have been greatly developed.

With the rapid development of solar photovoltaic technology, the cost of power generation is also dropping rapidly. As a clean energy, solar energy is a renewable energy that can be used freely. Solar photovoltaic technology can be used for a long time with one investment, and will surely become one of the important energy sources for sustainable development.
