Class A+A+A+ high-precision lab tester for IV measurements of solar cells

The CetisPV-Moduletest4-BF is an IV measurement system developed to high-end R%D, laboratory and quality control demands that allows the measuring of solar modules based on all cell technologies including TOPCon and HJT.

The programmable pulsed solar simulator with the CetisPV-MB-G2 flash unit provides a highly stable irradiance over long flash durations from a single light source. It ensures class A+A+A+ at irradiances from 500Wm² to 1.300Wm². The range of irradiances can be expanded to 100Wm² to 1.300Wm² with the optional neutral density filter CetisPV-NDF2.

Combined with the halm IV curve tracer and halm’s single-flash advanced hysteresis method PVControl-SF-hyst to measure high-capacitance modules, this system is designed to meet demands of current and upcoming solar cell and module technologies.

The versatile system can be equipped with different hard and software options such as dark IV, The electroluminescence imaging solution or temperature-controlled test chamber.
