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. ; De Castro, F.; Salvini, A. Irradiance intensity dependence of the lumped parameters of the three diodes model for organic solar cells. And we do this by setting up an equivalent circuit to the solar cell. Kim, T.; Kim, J.-H.; Kang, T.E. The equivalent circuit for the most used solar cell model consists of a diode and a current source connected in parallel, as well as a shunt resistor and a series resistor , as shown in Figure 3.

To understand the electronic behaviour of a solar cell, it is useful to create its model which is electrically equivalent at the solar cell. The equivalent circuit generally used for photovoltaic solar cells is shown in Fig. 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. conceived and wrote the paper and designed and performed the simulations; G.H. For the ideal solar cell, Rswould be zero, and would be infinite. The value of the series resistance Rs, is typically much lower than the parallel resistance Rp (sometimes referred to as the shunt resistance Rsh). The ideal current source delivers current in proportion to the solar flux to which it is exposed. The PV array: Its function is the conversion of solar radiation into electricity.

Equivalent Circuit Photovoltaic Solar Cell Performance Models The “five-parameter model” is a performance model for photovoltaic solar cells that predicts the voltage and current output by representing the cells as an equivalent elec-trical circuit with radiation and temperature-dependent components. The chapter is written for the device and system engineers and scientists. This is the equivalent circuit for a solar cell: The idea here is that the solar cell generates an internal current corresponding to the light intensity.
