  • Power Generation Principle Of Solar Panel
    Jan 13, 2018

    The sun shines on the semiconductor n Junction, forming a new hole-electron pair, under the action of N Junction electric field, the hole flows from P region to n region, electrons flow from N region to P region, and the electric current is formed after the circuit is connected. This is the photoelectric effect of solar cells working principle.

    There are two ways to generate solar power in solar power, one is the optical-thermal-electric conversion, the other is the direct conversion of light and electricity.

    (1) Light-heat-electric conversion by the use of solar radiation generated by thermal energy generation, generally by the solar collectors will be absorbed by the heat energy into the refrigerant steam, and then drive the turbine power generation. The previous process is the light-heat conversion process; The latter process is the thermal-electrical conversion process.

    (2) The direct conversion of light and electricity is the use of photoelectric effect, the solar radiation directly into the electrical energy, the basic device of light-electricity conversion is solar cells. A solar cell is a device that converts sunlight directly into electricity by the Yu Guangsheng Volt effect and is a semiconductor photodiode, which, when the sun shines on a photodiode, converts the sun's light energy into electricity and generates electricity. When many batteries in series or in parallel, can become a relatively large output power of the solar array.
