Thanks to the materials they are made of, when the sun's rays strike them directly, the electrons contained in the more external layers of the photovoltaic cells absorb the radiation and generate direct current electricity.
For the photovoltaic cells with constant resistance load, the output voltage, current, and output power of the photovoltaic cells decrease obviously with the increase of the temperature of the photovoltaic cells, and the photoelectric conversion rate of the photovoltaic cells shows a linear downward trend.
The results showed that solar radiation has a direct effect on the temperature of the cell as this temperature increases with the increase of solar radiation. Due to the increased temperature, it became the main cause of the decline of the output of the cell.
Through the above research and analysis, it is concluded that the output voltage, current, and photoelectric conversion rate of solar photovoltaic cells are closely related to the light intensity and the cell temperature.
The operation of a solar photovoltaic plant is based on photons and light energy from the sun’s rays. The types of solar panels used in these types of facilities are also different.
