Is solar energy photovoltaic?

Photovoltaics belongs to solar energy, but solar energy is more than just photovoltaics. There are two ways to use solar energy: photothermal conversion and photoelectric conversion are an emerging renewable energy source. Solar energy in a broad sense also includes wind energy, chemical energy, hydropower, etc. on earth. Humanity's direct use of solar energy is still in its infancy, mainly including solar heat collection, solar water heating systems, solar greenhouses, solar power generation, solar monitoring wireless and other methods.
