There are two types of solar power generation: one is light-heat-electric conversion, and the other is light-electric direct conversion. When the light illuminates the surface of the solar cell, part of the photons are absorbed by the silicon material; the energy of the photons is transferred to the silicon atoms, causing the electrons to transition, and the free electrons are concentrated on both sides of the PN junction to form a potential difference when the circuit is externally connected. Under the action of this voltage, there will be a current flowing through the external circuit to generate a certain output power. The essence of this process is the process of converting photon energy into electrical energy.
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 heat energy into the working medium vapor, and then drives the steam turbine to generate electricity. The former process is the light-to-heat conversion process; the latter process is the thermo-electric conversion process, which is the same as ordinary thermal power generation.
2, light-electric direct conversion mode This method is to use photoelectric effect, the solar radiation energy is directly converted into electrical energy, the basic device of light-to-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.
