Keysight Technologies Characterizing the I-V Curve of Solar Cells and Modules Measurement Tips Volume 7, Number 2 Application Note Explosive growth in the solar industry has intensiied the Characterizing the I-V curve from Isc to Voc need for test and measurement solutions that can quickly Characterizing a solar cell from the short circuit current and accurately capture the I-V curve characteristics of solar (Isc) to the open circuit voltage (Voc) requires a device with cells and modules. Because solar technology is being used a voltage range that covers Voc and can sink Isc. Charac- in residential, commercial and military applications, solar terizing the I-V curve is typically accomplished by stepping cells and modules are developed in a wide range of power the voltage from Isc to Voc. At each voltage step the current levels and with various conversion eficiencies. Also, the is measured. This can be achieved using an electronic load different testing stages -- research, quality assurance and or a two-quadrant DC source. production -- have different needs for measurement speed, measurement accuracy and the range of device characteris-
