This document describes a SPICE model for simulating a solar cell. It includes the SPICE model code, equivalent circuit symbol, and descriptions of how varying key model parameters affects the simulation results. The parameters studied are the series resistance (R_RS1), shunt resistance (R_Rsh1), diode saturation current (IS), diode emission coefficient (N), and diode series resistance (RS). The document shows that decreasing the shunt resistance or increasing the series resistance, saturation current, emission coefficient, or diode series resistance decreases the performance of the solar cell in the simulation.
