Modeling through Formalization of Photovoltaic Cell

A photovoltaic (PV) cell has several variable factors because it converts light to electricity. The analysis of PV cells requires weather datum characteristics, such as irradiance and temperature, as well as electric characteristics, such as current, voltage, and power. In addition, owing to technological development, various PV cell types are utilized in the market, so the diode ideality factor and energy bandgap of each PV cell should be considered. It is important to use an accurate model for the PV cells considering these variables. This paper presents detailed modeling considering not only the basic electrical characteristics of the PV cells, but also the effects of irradiance, temperature, and energy bandgap on the parameters. The chosen equalization model for the PV cell was a single-diode model with both series and parallel resistors to improve accuracy. The detailed modeling was simulated using Simulink software because of its effectiveness.
