Gosan Tech
Gosan Tech / Gosantech is a South Korea-based manufacturer of inkjet process equipment for display and solar cell production.
Established in 2015, Gosantech's team of inkjet process and equipment experts and has been recognized for its excellent R&D performance, supplying to big display panel manufacturers and equipment manufacturers in Korea.
Gosantech has developed new equipment for Perovskite Inkjet Process and is supplying equipment to Perovskite Solar Cell manufacturers. Gosantech has inkjet printing devices and equipment technology that can be applied not only to rigid substrates based on glass, but also to roll-to-roll processes based on flexible substrates, and has secured durability and chemical resistance to strong solvents that are inevitably used.
In order to improve the quality of Perovskite film using the inkjet process, a printing algorithm (developed in-house) can be applied, and printing technology using AI is also planned to be applied.

Epson increases investment in Gosan Tech to expand inkjet manufacturing for perovskite solar modules
Seiko Epson Corporation and Epson X Investment Corporation have made an additional investment in South Korean startup Gosan Tech through their joint fund, EP-GB L.P., with the stated aim of expanding the market for inkjet-based manufacturing systems for perovskite solar cell (PSC) modules.
Gosan Tech, founded in 2015, began in OLED display fabrication, developing and selling inkjet systems for producing OLED panels. That work yielded an ink supply system, pressure control technology and simulation technology that together deliver high ink droplet uniformity and precision - capabilities the company has since carried into other domains. Its business now spans three areas: information technology, covering OLED display fabrication and direct parts marking; environment, centered on inkjet systems for perovskite solar cells; and bio-medical, including drug deposition, tissue engineering and diagnostics.
NPC Corporation invests in South Korea’s Gosan Tech to strengthen perovskite solar cell equipment collaboration
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 and NPC announce strategic partnership focused on perovskite PVs
South Korea’s Gosan Tech has announced a strategic partnership with NPC Incorporated to jointly develop, manufacture, and market equipment for perovskite solar photovoltaic (PV) modules.
This alliance aims to leverage Gosan Tech’s advanced inkjet printing technology to improve production processes for perovskite solar modules, targeting PV module manufacturers in Japan and the United States, with initial sales contributions expected to begin in the fiscal year ending August 31, 2027. Although the immediate financial impact is minor, the partnership is expected to boost NPC's results and position both companies in the growing perovskite PV module market.
KRICT transfers inkjet printing technology to Gosan Tech for perovskite solar cell production
The Korea Research Institute of Chemical Technology (KRICT) recently announced that it has signed a contract to transfer core technology and materials for inkjet printing that can mass-produce perovskite solar cells to Gosan Tech.
The research team at KRICT developed the "inkjet printing" technology that reportedly overcomes the limitations of the process for precisely stacking thin films of perovskite solar cells. Gosan Tech plans to cooperate with KRICT to achieve technology independence.
Gosan Tech secures funding from Epson
Seiko Epson Corporation and Epson X Investment Corporation have invested in South Korean Gosan Tech through a joint fund, the EP-GB L.P.
Founded in 2015, Gosan Tech develops and sells inkjet systems for fabricating organic light-emitting diode (OLED) displays and perovskite solar cells. Through its work in this field, it has developed an ink supply system, pressure control technology, and simulation technology that enable it to achieve excellent ink droplet uniformity and precision. Gosan Tech is expanding its business in three areas: information technology, including OLED display fabrication and direct parts marking; the environment, with inkjet systems for perovskite solar cells; and bio-medical, including drug deposition, tissue engineering, and diagnostic.
