By analyzing its relationship with influencing factors, the impact analysis on the power generation performance of photovoltaic cells was realized. 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.
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.
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.
At present, there are two main methods to study the performance of solar photovoltaic cells: numerical simulation and finite element analysis. Kohan et al. established a three-dimensional numerical model of photovoltaic modules and TEG devices .
It can be seen from the table that photovoltaic cell change. less than 1 A to more than 7 A. When the light intensity in fluence factors. Under different light intensities, the total energy of light on the battery board is di fferent.
The light intensity loading on the panel will cause its own temperature change. Therefore, the light intensity on the surface of the PV module and the corresponding output voltage and current data are analyzed under different temperatures of the PV cell.
