Sofab Inks, Inc.

Sofab Inks, Inc. , based in the US, specializes in developing high-performance nanoparticles for solar perovskite applications, offering innovative solutions for enhancing solar cell technology. Founded in 2022, Sofab Inks, Inc. operates out of Louisville, US, focusing on the creation of specialized ink products for the solar energy sector.

The company has successfully completed 1 deal, with the most recent funding round occurring on June 16, 2025, where it raised USD 903,000. The firm has consistently pursued advances in material development to support the renewable energy market. Sofab Inks specializes in high-performance nanoparticles primarily for solar perovskite applications. Their core products include Tinfab (SnO2) as an Electron Transport Layer (ETL) and NicFab (NiO) as a Hole Transport Layer (HTL).

Tinfab is engineered to be solution-processable in both PIN and NIP architectures, offering durability that is 2-3 times greater than traditional fullerenes, while maintaining efficiency for solar cell applications. NicFab serves as a cost-effective inorganic alternative to PTAA, promoting crystal growth and featuring strong band alignment. These products are designed for scalability and efficiency in manufacturing, targeting industries involved in renewable energy and solar technology. Sofab’s clientele includes manufacturers and researchers in the solar energy sector located in North America, Europe, and parts of Asia, all seeking to enhance the performance and durability of their solar cells.

Sofab Inks generates revenue through B2B partnerships with companies in the solar energy sector, focusing on custom nanoparticle solutions for high-volume manufacturing applications. Transactions typically involve direct sales agreements where clients procure bulk quantities of Tinfab and NicFab nanoparticles for integration into their solar cell technologies. Pricing structures are based on volume and customization requirements, reflecting the specific needs of each client. As manufacturers implement Sofab’s products, they benefit from the cost advantages and performance enhancements offered by these proprietary materials, solidifying long-term partnerships.

By fostering collaboration and joint development opportunities, Sofab aims to create scalable solutions that align with its clients' production capabilities and market demands. In June 2025, Sofab Inks, Inc. raised USD 903,000 in venture funding from unspecified investors. The company will use the funding to expand its specialized ink product line and accelerate the development of materials for perovskite solar cell manufacturing.

Future plans include launching new products targeting advanced applications in the solar energy market and expanding into more markets across Europe and Asia by the end of 2026.
