IV-21 Solar Cell I-V Measurement System

Measure the I-V characteristics of large solar cells with the IV21 Solar Cell I-V Measurement System. The turn-key system irradiates an area up to 210 mm x 210 mm in size with a class ABA or class AAA solar simulator and characterizes their critical parameters such as Voc, Isc, Jsc, Vmax, Imax, Pmax, and efficiency.

This system includes the light source and measurement equipment needed to measure solar cell I-V curves on cells up to 21 cm x 21 cm. Its solar simulator illuminates the test device while the electronic load sweeps the cell voltage from a reverse-bias condition, through the power quadrant, and beyond Voc. Synchronized, precise voltage and current measurements form an I-V curve. The system’s computer gathers data, calculates solar cell parameters, generates printable test reports, and saves test data in text files so that data can easily be shared for further study. Sweep range, direction, and rate are adjustable.
