PV solar cell mathematical modeling. This work presents a practical circuit model for a PV solar cell, with the goal of increasing its realism. The model shows a true setup of single diode with shunt resistor (\ (R_ { { {\text {sh}}}}\)) that captures current leakage caused by cell surface effects and thickness.

Is a solar cell a diode or a cathode?

The solar cell is normally a diode, it conducts electrons unidirectionally from the anode to the cathode, and it blocks the flow of electrons in the reverse direction. In forwarding, biased condition acts as null resistance and reverse biased acts as the unbounded resistance condition. The proper behavior of the real diode is shown in Equation 3.
