PV power generation technology is one of the most important forms of large-scale centralized and efficient use of solar energy [ 1, 2, 3 ]. PV cell modeling is an important basis for the research of PV power generation and related technologies. Many scholars have conducted a lot of model research on PV modules.
2. During the use of solar cells, the light incidence angle should be kept in the range of 0°–30° to ensure that the short-circuit current, maximum working power and photoelectric conversion efficiency of solar cells are less affected by the light incidence angle and improve the efficiency of solar energy utilization.
