Holyvolt is a Stockholm-based battery and solar-cell technology company, founded in 2022, that has developed a proprietary screen-printing (Nanopaste) manufacturing process for producing high-performance, low-cost battery and thin-film solar cells with a reduced environmental footprint. The company, which also runs a product-development lab in Munich, is backed by Volvo Cars and the Wallenberg family's investment firm FAM, and in March 2026 it acquired US battery-materials firm Wildcat Discovery Technologies to add high-throughput materials discovery to its manufacturing platform.
