How solar cells work

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

(1) The light-thermal-electrical conversion method generates electricity by utilizing the thermal energy generated by solar radiation. Generally, the solar collector collects the absorbed thermal energy into the working medium vapor, and then drives the steam turbine to generate electricity. The former process is a photo-thermal conversion process; the latter process is a thermo-electric conversion process.

(2) The direct conversion method of light-electricity uses the photoelectric effect to directly convert solar radiation energy into electrical energy. The basic device for photoelectric-electrical conversion is solar cells. A solar cell is a device that converts solar energy directly into electrical energy due to the photovoltaic effect. It is a semiconductor photodiode. When the sun shines on the photodiode, the photodiode turns the solar light into electrical energy. Current. When many batteries are connected in series or in parallel, they can become a square of solar cells with relatively large output power.
