Company bio

Saule S.A. Saule Technologies is a pioneer in the research and manufacturing of a new generation of perovskite solar cells. The solar cells printed on flexible foils are lightweight, ultra-thin, and semi-transparent, which significantly surpasses the range of possible applications of traditional silicon technology. The company was founded in 2014 by Olga Malinkiewicz, the inventor of the printing method, and experienced businessmen – Piotr Krych and Artur Kupczunas. Today, Saule Technologies is a team of over 50 scientists, engineers, and administrative staff from over 17 countries, working in an R&D center with a pilot production line and one of Europe’s best-equipped optoelectronics laboratory. Releasing products available for licensing and first B2B sales in early 2021 proves that Saule Technologies is a leader in commercializing perovskite solar cells.
