Halm - Model Celltest4 -Laboratory Cell Tester
Our base model, Celltest4, is a state-of-the-art laboratory cell tester for the PV industry. It features a flexible system layout and a wide range of optional hardware extensions such as EL [electroluminescence] imaging, hotspot (IR) detection and a spectral response measurement option, as well as additional software options. Taken together, these extensions can transform Celltest4 into a fully integrated cell characterization system.
The tester offers a wide range of customizable measurement parameters and advanced analyses to measure cells. It also enables extremely long flash durations, an important factor when examining or measuring modern, high-capacity solar cells. Advanced analytical methods such as SunsVoc, 2-Diode-Fit and doping concentration are also available as a software feature.
The lab tester`s cell contacting feature can be configured to accommodate the desired cell type and geometry. Contacting options include conventional pin contacting and advanced contacting layouts for e.g. busbar-less solar cells.
The Celltest4 can also be retrofitted to a Celltest4-BF later, making it a future-proof investment.
