The experimental results show that the open circuit voltage, short-circuit current, and maximum output power of solar cells increase with the increase of light intensity. Therefore, it can be known that the greater the light intensity, the better the power generation performance of the solar cell. 1. Introduction
Solar cells experience daily variations in light intensity, with the incident power from the sun varying between 0 and 1 kW/m 2. At low light levels, the effect of the shunt resistance becomes increasingly important.
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.
The annual total power generation and heat gain are analyzed as experimental research data, and the investment cost of research methods for the influence of different light intensities on the power generation performance of photovoltaic cells is carried out.
It is concluded that when the light intensity gradually increases, the open circuit voltage and short-circuit current of the trough solar photovoltaic cell gradually increase; the open circuit voltage and short-circuit current of the trough solar photovoltaic cell gradually increase.
It identifies essential variables, such as solar radiation, relative humidity, and module surface temperature, that influence power generation. Regression equations were derived for PV and PVT. Results show that solar radiation plays a significant role in winter, while multiple factors affect summer power generation.
