The building of thin-film solar cell production equipment requires a constructive synergy between machine, process and materials know-how.

44solar is a joint effort between the R&D background of John Kessler, the process control and equipment design expertise of Martin Bresch and Daniel Köhn, and the industrial scale vacuum machine building experience of Maxwell Choi.

44solar addresses the market for thin-film solar cell production equipment in close collaboration with its established partners MacroTech Steuerungstechnik GmbH and VTC, Korea Vac-Tec Co.,Ltd.

44solar masters both the tools and the tasks. We do not just sell equipment, we sell equipment that works.
