en.Wedoany.com Reported - German solar research institute ISC Konstanz (International Solar Energy Research Center) has announced that its internally built, fully integrated industrial-grade solar cell and module pilot line is expected to be commissioned in the third quarter of 2026. The cleanroom is currently being equipped with high-temperature processing systems supplied by centrotherm and automation equipment from Jonas & Redmann to support oxidation, diffusion, CVD, and PALD processes on current industrial wafer sizes.
ISC Konstanz stated that once operational, the line will enable all cleanroom processes required for solar cell development to be completed in-house for the first time. The expanded pilot line equipment includes batch wet benches from RENA Technologies, PVD equipment from Von Ardenne, high-temperature rapid firing furnaces from centrotherm, an extended ASYS printing line with copper printing curing ovens, a laminator from Bürkle, a back-contact cell stringer from Mondragon Assembly, and a HALM benchtop LED IV measurement system for tandem applications. The institute noted that this expansion will re-establish a service model allowing industrial partners to directly use its infrastructure for technology development, process validation, and prototype manufacturing.
ISC Konstanz co-founder Radovan Kopecek pointed out that the new infrastructure enables a closer integration of industrial development and applied research, allowing companies to use modern industrial equipment at ISC, develop and optimize processes together with the team, and even manufacture small pilot series for specific applications. The cleanroom upgrade is the final step in a large-scale, phased infrastructure build-out. Industrial partners can access the equipment through a leasing model, perform prototype processing within ISC's facilities, obtain contract research services, and participate in hands-on training on industrial-grade manufacturing equipment. The expanded line will also support small-batch production of specialized solar cells and modules with a higher degree of automation.
Recently, ISC Konstanz entered into a cooperation with Indian renewable energy company Celloraa Energy to provide technical support for the construction of a 1.2 GW Tunnel Oxide Passivated Contact (TOPCon) solar cell production facility in Gujarat, India. Under the agreement, ISC Konstanz has been designated as the primary technology and certification partner for the project, assisting Celloraa Energy in expanding India's domestic solar cell manufacturing capacity.
