Solar cells are a form of photoelectric cell, defined as a device whose electrical characteristics – such as current, voltage, or resistance– vary when exposed to light. title = "Equivalent circuit approach to solar cell modeling". An ideal solar cell may be modelled by a current source in parallel with a diode; in practice no solar cell is ideal, so a shunt resistance and a series resistance component are added to the model. MODULE -3 Equivalent Circuit and Shading MEE 1038 – Solar Photovoltaic System Because no solar cell is ideal, a shunt resistance and a series resistance component are therefore added to the model to have the equivalent circuit. We shall illustrate this by an example in which monochromatic light is applied to one side of a p+/n junction cell.
