The Institute of Solid State Physics, University of Latvia (ISSP UL) has marked an important milestone with the official launch of our reactive sputtering Roll-to-Roll (R2R) deposition equipment. This achievement is a breakthrough for the Thin Film Laboratory, and it positions Latvia at the forefront of advanced materials research in Widening countries. With this installation, ISSP UL is now the only research center in the Baltic States to operate such technology, creating unique opportunities to push the boundaries of science and strengthen collaboration with industry.
The new R2R platform allows researchers to scale up thin-film deposition from small laboratory samples to continuous industrial-scale processes. Its sophisticated configuration includes a wide rotating drum heated up to 350°C, adjustable web speeds and controlled tension, and four magnetrons with four process gases for high-precision thin film coating. These features open the way to innovative applications in smart coatings, energy-efficient devices, and flexible electronics.
The Smart Thin Film and Coating Technologies Group, led by Dr. Mārtiņš Zubkins, will lead the scientific activities using the equipment. The project reflects both the scientific ambition and a story of dedication: Dr. Lauris Dimitročenko and Dr. Aleksandr Sazonov played a central role by fully refurbishing the system, creating tailor-made infrastructure solutions, and building custom control software from the ground up. Their work has transformed the equipment into a modern, high-performing research tool, tailored to the needs of both academic research and industrial collaboration.
The launch was made possible through the Smart Windows for Zero Energy Buildings project funded under the Horizon Europe program and the strong leadership of Prof. Juris Purāns, Head of the Thin Films Laboratory. The installation of the R2R platform directly supports the SWEB objectives of advancing thin-film science in Latvia, building excellence that contributes to the European Research Area, and accelerating Europe’s transition toward climate neutrality through innovative, energy-efficient materials.
Reflecting on the launch, Prof. Purāns highlighted that the tool marks a turning point for ISSP UL: “With the Roll-to-Roll system, we are now able to move from lab-scale experiments to industrial-scale prototypes. This strengthens our role in the European Research Area and creates a bridge for closer cooperation with industry.”
The SWEB team welcomes opportunities to work with industrial partners in joint research, technology transfer and pilot demonstrators. By opening its doors to collaboration, ISSP UL reinforces its role as a hub where science and business meet, driving innovation that serves both the Latvian economy and Europe’s wider green and digital transition.
