I-V Curve Measurements

CPVMCL is accredited to preform current-voltage (I-V curve) measurements at Standard Test Conditions (STC) according to IEC60904-1 for a wide range of devices. These span from research scale devices from 10 mm x 10 mm up to commercial modules of 2.5 m x 2.5 m in size. Cells are measured with a steady state dual-light-source solar simulator and modules are measured with a pulsed light solar simulator. Section measurement are performed to minimise hysteresis effects. All measurements are traceable to SI units and the perfomance parameters (i.e. PMAX, VOC, ISC, η) are acompanied with uncertainty estimates validated through international inter-comparissons.
