cell production measuring technology for highly reliable data
More than 2000 halm systems are already installed in the field, all of which fully comply with the IEC60904-9 standard. In the latest standard (Edition 3.0), our current systems are even rated A+A+A+.
Our rigorous modular system design guarantees almost all our products can be upgraded, resulting in benchmark investment security. For example, the measurement and power electronics of our production systems are identical to those used in the laboratory systems. In principle, therefore, individual components can be interchanged between both system types. Consequently, if a component in a production tester should malfunction, the client can borrow a part from their laboratory tester to keep the system running.
unrivaled end of line control for a competitive advantage
which solution is perfect for your needs?
Our measurement technology is remarkable for its particularly stable illumination. This provides highly accurate and repeatable data that can be relied upon and enhances plant process controls accordingly. Ultimately, this performance data determines how much solar cell manufacturers can earn with their products.
halm – future-proof modular investments
We never compromise on quality. As a result, our systems and their precision are stable over the long term and have a very low failure rate. This eliminates downtime and stoppages in production lines through malfunctions.
our measurement systems for the mass production of solar cells
IUCT-LF3.1
The IUCT-LF3.1 is a high-precision IV tester with LED solar simulator designed for testing solar cells with unparalleled accuracy.
This class A+ A+ A+ certified system is equipped with LED technology with 28+ wavelengths covering a spectral range of 300-1,200 nm. The system is available in two versions: the standard monofacial model and the IUCT-LF3.1-BF with dual synchronized light sources for bifacial testing. Both models offer adjustable light spectra and unlimited flash durations including constant light mode, making them ideal for testing tandem and multi-junction solar cells and perovskite materials.
With its modular, air-cooled light engine, the system ensures productive and convenient operation in all industrial environments.
Optional packages include EL imaging, IR imaging, grid resistance testing, and simultaneous measurement of two half-cut cells. The base model already comprises MPP tracking functionality, spectral response measurement, and EQE evaluation, providing a comprehensive solution for solar performance testing in production settings.
IUCT-SoluX-S
The IUCT-SoluX-S is a high-speed IV tester with a programmable solar simulator designed for the highly precise and reliable testing of monofacial solar cells.
This class A+A+A+ certified system sets a new standard in cell testing, delivering precise measurements in a single flash thanks to halm’s advanced hysteresis. It offers highly stable irradiance output over long flash times, ensuring best-in-class repeatability and reproducibility. Built for versatility, the system is capable of measuring large-format solar cells up to 240 mm x 240 mm, making it fully compatible with the latest cell generations.
Engineered for maximum uptime in demanding manufacturing environments, the system features a next-generation, long-life flash tube that significantly reduces the cost of ownership. It is optimized for high-volume production lines, achieving an exceptional throughput of 5,500 cells per hour and above. Additionally, its modular design allows for the seamless integration of optional process controls, including EL/IR imaging and grid resistance analysis.
IUCT-SoluX-BF
The IUCT-SoluX-BF is a high-speed IV tester and solar simulator designed for the rapid and highly precise assessment of bifacial solar cells.
