Sofab Inks Raises $6M Seed Led by Cloudberry Ventures

Sofab Inks, a perovskite solar materials company spun out of the University of Louisville, has raised $6 million in seed funding.

The round was led by Cloudberry Ventures. The company develops specialized inks and electron transport layers for perovskite solar cells, a technology that promises cheaper, more efficient panels than standard silicon.

Sofab started at the university's Conn Center for Renewable Energy with backing from the U.S. Department of Energy. The seed money will support production scaling as the industry tries to move perovskite from lab to factory floor.

Perovskite solar has drawn heavy venture interest but has struggled with durability and manufacturing consistency. Sofab's focus on materials that improve cell stability and printing compatibility positions it for the next wave of pilot production lines, the company said.
