Introduction of two power generation methods of Solar Panels

(1) The light-heat-electric conversion method uses solar radiation to generate electricity. Generally, the solar collector in Solar Panels converts the absorbed heat into vapor of the working fluid, and then drives the steam turbine to generate electricity. The former process is a light-heat conversion process; the latter process is a heat-electric conversion process.

(2) The light-electricity direct conversion method uses the photoelectric effect to directly convert solar radiant energy into electrical energy. The basic device of the light-electricity conversion is the solar cell. A solar cell is a device that directly converts sunlight energy into electrical energy due to the photovoltaic effect. It is a semiconductor photodiode. When the sun shines on the photodiode, the photodiode will turn the sun’s light energy into electrical energy to produce Current. When many batteries are connected in series or in parallel, a square array of solar cells with relatively large output power can be formed.
