What Saule Technologies does
Saule Technologies is a Polish nanotechnology company, founded in November 2014 by Olga Malinkiewicz, Piotr Krych and Artur Kupczunas, that develops inkjet-printed perovskite solar cells on thin, flexible PET substrates. The core technology — a patented low-temperature (below 120°C) inkjet deposition method invented by Malinkiewicz — produces cells thinner than a micron and approximately 500 g/m², capable of up to 25–31% efficiency in indoor and low-light conditions and roughly 10% under one sun, with customisable shape, colour and transparency. The company operates a pilot production line in Wroclaw and an additional corporate office in Warsaw, with a team of 50+ scientists, engineers and administrative staff drawn from more than 17 countries.
The business model is B2B, combining (i) exclusive technology licensing and OEM partnerships, (ii) direct sales of customised products spanning IoT (electronic shelf labels, smart-home devices), E-Mobility (solar carports, EV-charging canopies, yacht sails, truck tarpaulins), Building Applied Photovoltaics (lightweight rooftops, sunblinds, awnings) and Building Integrated Photovoltaics (photovoltaic glass, facades), and (iii) R&D and joint-development services. Named customers and partners include Skanska, Somfy, H.I.S. Co., Ltd., Lawson, Columbus Energy (also a 20% equity holder since September 2020), Henn-na Hotel (Japan), Natoni and the European Bison conservation project, most engagements to date being pilots, demonstrators or co-development programmes rather than disclosed volume contracts.
Operationally, Saule moved from laboratory to industrial scale with the May 2021 grand opening of its pilot line and its first commercial BAPV installation in August 2021, and has since entered Japan through Tokyo retail trials (December 2024) and the 2025 World Expo in Osaka-Kansai. The company announced readiness to go public via a reverse merger of Blumerang Investors on the Warsaw NewConnect market in April 2021, though no completed listing is documented in the source data. As of mid-2026, the management board publicly disputes unauthorised offers to purchase the company or its assets.
