HighLine with new partners on its way towards market entry 2021

The High-Tech Gründerfonds (HTGF) and Fraunhofer Technologie Transferfonds GmbH (FTTF) invest in the Tech Start-up HighLine Technology GmbH. HighLine develops high precision printing technology for the semiconductor industry with current focus on solar cells. The seed investment amounts to EUR 1.2 million and is contributed equally by the HTGF and FTTF.

The use of solar energy represents a central pillar of the future energy supply. However, scaling of the corresponding PV systems also entails the need for more efficient input of resources. In particular silver, which is applied for the conductor lines on the cells, represents a major cost factor in the production of solar cells. Accordingly, PV manufacturers and other semiconductor industries are looking for more efficient printing processes to apply respective media. Our parallel dispensing technology enables significant process optimization in terms of silver consumption, cell and module efficiency and production throughput.

Dr. Maximilian Pospischil, co-founder and managing director of HighLine

With the HighLine parallel dispensing print heads the surface of the solar cell can be metallized in one crossing. The current printing speed of 500mm / s (LT paste for HJT) enables a higher throughput than with established competitive processes. Furthermore, thanks to the impressive homogeneity of the tiny contact fingers, more than 20% silver is saved and the efficiency of the solar cell is also increased by reducing the shadowing losses. For quick market entry, HighLine has developed a solution for integration into industrial screen printing platforms – the “cuckoo”. This means that existing production lines of established system manufacturers can be equipped with the new printing technology within short time. A demonstrator can currently be seen in the PV-TEC laboratory of Fraunhofer ISE.

So far the industrialization of the technology originated from Fraunhofer ISE has been supported by the EXIST Forschungstransfer (BMWi) and PreSeed funding by the FTTF and the L-Bank BW.

The technological developments achieved in the pre-seed phase and the positive feedback from established customers and partners confirm the clear business case of Highline, so I’m looking forward to the next steps for market entry.

Tobias Schwind, Managing Partner at FTTF

Thanks to our dedicated team we achieved great development progress in 2020. Based on this financing round and together with our industrial partners, we can introduce the technology to the PV market via a field test in 2021. This means that the market entry takes place in line with the current revival of the PV industry in Europe.

Marian Breitenbücher, co-founder and managing director of HighLine

Dispensing technology offers very short ROI for solar cell manufacturers and therefore has the potential to replace established screen-printing platform in this market in the medium term. In my opinion, the technical status that has already been achieved and the strengths of the team form an excellent basis for a successful and sustainable market launch.
