What are the two types of solar power generation

There are two major types of electricity generation using solar energy: solar photovoltaic (solar photovoltaic) and solar thermal (solar thermal).

① Solar photovoltaic power generation - is a way of generating electricity by directly converting solar energy into electricity. It includes: photovoltaic power generation, photochemical power generation, light induction power generation and photobiological power generation in four forms, of which photochemical power generation are: electrochemical photovoltaic cells, photoelectrolytic cells and photocatalytic cells.?

② solar thermal power generation - is the first solar energy into thermal energy, and then thermal energy into electricity, it has two conversion methods:

One is the direct conversion of solar thermal energy into electricity.

The other way is to generate electricity from solar thermal energy by driving a generator through a heat engine.

Expanded Information:

The energy source of solar energy is the energy that comes from celestial bodies external to the Earth The energy (mainly solar) is the enormous energy released by the fusion of hydrogen nuclei in the sun at ultra-high temperatures, and the vast majority of the energy needed by humans comes directly or indirectly from the sun.

The fossil fuels we need for our lives, such as coal, oil, and natural gas, are all due to the fact that a variety of plants through photosynthesis convert solar energy into chemical energy stored in the body of the plant, and then by the plants and animals buried in the ground after a long geologic era of formation. In addition, water energy, wind energy, wave energy, ocean current energy, etc. are also converted from solar energy.

Solar power is a device that uses a battery module to convert solar energy directly into electricity. Solar modules is the use of semiconductor materials, the electronic properties of solid devices to achieve P-V conversion, in the vast areas without power grid, the device can be easily realized for the user's lighting and living power supply, some developed countries can also be realized with the regional power grid grid to complement each other.

From the civil point of view, in foreign countries, technology research tends to mature and the beginning of industrialization is "photovoltaic - building (lighting) integration" technology, while the main domestic research and production of small-scale solar power generation systems suitable for home lighting in areas without electricity.
