Modular Turnkey Systems for Solar Cell Measurements
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.
Halm - Model Celltest4-BF - Modular Turnkey System
The BF in Celltest4-BF stands for bifacial, and is a system that enables synchronous illumination of the front and back of the cell, allowing precise determination of its overall performance. This makes a detailed investigation of the cell in different illumination situations possible. The intensities and illumination times of the individual light sources (flasher) can be configured independently. It permits particularly long illumination times (flash durations) and offers a wide range of customizable measurement parameters and advanced analyses for measuring cells. Advanced software analysis methods such as SunsVoc, 2-diode fit, and doping concentration are optionally available.
