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.

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-3600-BF
halm's IUCT-3600-BF is a bifacial system offering synchronous illumination of the front and back of the cell, resulting in a precision determination of the total cell output. Its throughputs are tailored to modern production lines with 3600 - 4000 cells/h.
The IUCT-3600-BF is the immediate successor to our IUCT-BF model, which was the first bifacial system on the market and, apart from a few optical components, identical in construction. As far as we can determine, it remains the only established bifacial measurement system in the manufacturing PV industry today.
It is subject to no restrictions in terms of the cell geometry or technology to be measured and, thanks to its modular design, can be upgraded at a later stage for higher throughputs (with only a small investment).
- Two synchronized xenon flashers with different illumination levels for rear and front
- Flexible flash profiles applicable within one measurement sequence
- Measurement under front and rear STC conditions and typical field conditions for bifacial solar cells (e.g. 1,000 W m-2 [front] and 200 W m-2 [rear])
- Ideal for high-throughput production
- Measures high capacitive bifacial solar cells
- Illumination intensity of both flashers freely programmable
- Light sources also suitable for one-sided flashing
- Combinable with other tools for quality and process control
IUCT-4000
The IUCT-4000 system is our most affordable basic system for cell production measurement. Despite the relatively low investment, no sacrifice in performance is required (high throughput possible (4000 cells/h), and there is no limitation in terms of the cell geometry or technology that can be measured.
The current model originates from a long-proven model series based on XF2 power electronics, making it particularly fail-safe and tested in the field. The only minor drawback is that it cannot automatically be upgraded to a bifacial measurement system.

It is geared for potentially very high throughput with long illumination times, has ample power reserves, and has no limitations in terms of measurable cell geometry or technology.
