Japan-based NPC Corporation has announced that it has completed an equity investment in Gosan Tech, a South Korean manufacturer of inkjet coating equipment. NPC and Gosan signed a business cooperation agreement in September 2025 to jointly promote their technologies. Since then, the two companies have secured several project orders and expanded cooperation in equipment development and production.
NPC's investment is meant to strengthen technical collaboration, establish a stable supply system for coating equipment, and enhance competitiveness in the growing perovskite market. The partnership is expected to cover both business and capital cooperation, including R&D, production, and market expansion. NPC and Gosan plan to target perovskite projects in Japan and the U.S., where demand is rising.
Gosan Tech, founded in 2015, develops and manufactures inkjet coating equipment mainly used in OLED production. The company has been expanding its activities to perovskite solar cell equipment. Gosan’s strength lies in ink supply and pressure control technologies that improve droplet uniformity. In 2025, it received investment from Seiko Epson, allowing integration of Epson printheads compatible with solvents used in perovskite processes.
NPC has traditionally supplied equipment for the back-end process of solar cells and recently entered the perovskite field. The company and Gosan have already received orders for machines and production lines with inkjet coating units, which will be integrated into NPC’s Songshan factory production system.
After the investment, Gosan said it expects support from NPC in global sales and overseas market strategy and plans to continue developing its inkjet equipment and proprietary perovskite solar cells.
