Zener diode D2 is of course essential in this circuit as its zener voltage limits the output voltage when T1 should be turned on, connecting the solar cell array to ground via R3. The shunt resistance (R sh) in the equivalent circuit represents parasitic electron-hole recombination. based solar cell equivalent circuit diagram was implemented in P-Spice. Thanks, Now the diode is placed right after the solar cell so Q1 and Q2 are powered by the battery. A novel equivalen diagram of a solar cell is developed. Electrically the important parameters for determining the correct installation and performance are: 1. 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. The solar cell is effectively a diode with a reverse-bias current source provided by light-generated electrons and holes. It is a form of photoelectric cell, defined as a device whose electrical characteristics, such as current, voltage, or resistance, vary when exposed to light..
