Modeling and simulation of photovoltaic cell using single diode solar cell and double diode solar cell model

Abstract

Modeling and simulation of photovoltaic cells or PV cell is becoming important as it provides an easy platform to perform studies on photovoltaic cells and the design and analysis of the system based on photovoltaic cells. In this paper, we present our study of the ordinary photovoltaic module on the basis of one diode and two diode models. Studies are extended to solar cells as solar cells are similar to photodiodes. Performance of the solar cells may be described in terms of ideality factor (α), which decreases with temperature and is observed to affect the performance of the PV cell. PV systems exhibit better performance with diodes having higher values for α. In this paper, our efforts are to study the effects of α on Current and Power versus Voltage characteristics of the solar cells. MATLAB simulation of solar cell systems is a simple and elegant mechanism useful for designing and modeling the framework of the solar power plant.
