There are two ways of solar power generation, one is the light-heat-electric conversion method, and the other is the direct light-electric conversion method.

(1) The light-heat-dynamic-electric conversion method uses the thermal energy generated by solar radiation to generate electricity. 

Generally, the solar thermal collector converts the absorbed thermal energy into working medium vapor, and then drives the steam turbine to generate electricity. 

The former process is the light-heat conversion process; the latter process is the final conversion process of heat-kind conversion into electricity, which is the same as ordinary thermal power generation. 

The disadvantage of solar thermal power generation is its low efficiency and high cost. 

It is estimated that its investment At least 5-10 times more expensive than ordinary thermal power stations.

(2) Light-to-electric direct conversion method This method uses the photoelectric effect to directly convert solar radiation energy into electrical energy. 

The basic device for light-to-electric conversion is a solar cell. 

A solar cell is a device that directly converts solar energy into electrical energy due to the photovoltaic effect. It is a semiconductor photodiode. 

When the sun shines on the photodiode, the photodiode will convert the solar light energy into electrical energy. Current. 

When many cells are connected in series or in parallel, they can become a square array of solar cells with relatively large output power. Solar cell is a promising new power source with three advantages: permanent, clean and flexible. 

The solar cell has a long life. As long as the sun is present, the solar cell can be invested once and used for a long time. Compared with thermal power, Solar cells do not cause environmental pollution.
