About
Sofab Inks is a Louisville, Kentucky-based specialty materials company developing electron transport layer (ETL) materials for perovskite solar cells 123. The company was spun out of the University of Louisville’s Conn Center for Renewable Energy Research with support from the U.S. Department of Energy 12. On 2026-07-21, Sofab Inks announced a $6 million seed round led by Cloudberry Ventures 123. The company claims commercial engagement or late-stage discussions with approximately 90% of the perovskite industry, and the round arrives alongside a manufacturing reliability breakthrough for perovskite solar at scale 13.
