Number 1953 Measuring Photovoltaic Cell I-V Application Note Characteristics with the Model 2420 Series SourceMeter Instrument Introduction The series resistance (rs) represents the ohmic losses in the front surface of the cell and the shunt resistance (rsh) represents Photovoltaic (PV) cells convert sunlight directly to electricity. the loss due to diode leakage currents. The conversion efficiency Fabricated from a wide variety of materials using many different (h) is defined as: processing techniques, these devices are used for terrestrial power generation, as well as commercial, military, and research Pm h = ____ space power applications. PV cell characterization involves Pin measuring the cell's electrical performance characteristics to and the fill factor (FF) given by: determine conversion efficiency and critical equivalent circuit parameters. It is an important tool for R&D and production of ImVm FF = ______ cells and photovoltaic arrays. This application note describes IscVoc how to use the Keithley Model 2420 High Current SourceMeter
