Changing the light intensity incident on a solar cell changes all solar cell parameters, including the short-circuit current, the open-circuit voltage, the FF, the efficiency and the impact of series and shunt resistances.
Different angles and different light intensities have different effects on the performance of solar cells. When the light is radiated to the photovoltaic cell material, some of the incident light is reflected or scattered on the surface, and some of it is absorbed by the photovoltaic 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.
When light of the right wavelength shines on the semiconductor material of a solar cell, the light creates a flow of electrons. This is known as the photoelectric effect. Small solar cells, like the one used in this project, can be used in circuits to charge batteries, power a calculator, or light an LED (light emitting diode).
According to the data in Table 5, the output power of photovoltaic cells increases gradually with the increase of light intensity. When the light intensity increases to about 700, the output power tends to be saturated; when the light intensity is greater than 650, the growth rate of Pout is less than that of Pin.
The photoelectric conversion rate of the photovoltaic cell is the ratio of the output power of the photovoltaic cell to the total solar radiation power radiated on the surface of the photovoltaic cell:
