Halm - Model Celltest5 -IV Tester
The Celltest5 is a state-of-the-art IV tester designed for high-quality solar cell performance testing in laboratories and R&D environments. This advanced system features a unique LED light source with 28+ wavelengths covering a spectral range of 300-1,200 nm. The system is capable of unlimited flash duration and constant light operation.
For bifacial applications, the Celltest5-BF version features two identical, synchronized LED light sources that allow measurements with illumination on both front and rear side of solar cells.
Both systems meet the demanding requirements of various cell technologies, including tandem and multi-junction solar cells as well as perovskite materials, with adjustable light source spectrum capabilities.
The Celltest5 provides MPP tracking, spectral response and EQE measurement as well as additional advanced analysis tools including multiple series and shunt resistance measurements, advanced hysteresis evaluation, two-diode analysis, and SunsVoc measurements, ensuring reliable and comprehensive performance characterization for next-generation solar cell technologies.
Moreover, these systems are available with optional features such as EL and IR imaging and grid resistance testing.
