Extraction of Saturation Current and Ideality Factor from Measuring Voc and Isc of Photovoltaic Modules
(a) Dependence of ideality factor on voltage across the junction. At low voltages, Rsh dominates the device performances, while at high voltages, Rs dominates. (b) Effect of irradiance on voltage across the cell. The measurements in this document are confined to between 169 W/m2 and 1000 W/m2 as governed by the physical setup of the experiment.
