Epson Makes Additional Investment in Korean Inkjet Startup KosanTech... Targeting Next-Generation Solar Cell Market
Follow-Up Investment After Initial 2025 Funding
Strengthening Collaboration on Inkjet Processing for Perovskite Solar Cells
Seiko Epson (hereinafter Epson) announced on the 27th that it has made an additional investment in the domestic inkjet technology startup KosanTech through the fund 'EP-GB L.P.'
This investment follows a strategic partnership established in 2025. Both companies plan to further strengthen their collaboration based on inkjet technology in the next-generation perovskite solar cell (PSC) manufacturing sector.
Perovskite solar cells are regarded as a next-generation eco-friendly material due to their high energy conversion efficiency and flexible properties. By applying inkjet processing to the manufacturing process, materials can be precisely deposited only where needed, making it easier to reduce costs and enable large-area production.
Founded in 2015, KosanTech developed inkjet systems for manufacturing organic light-emitting diode (OLED) displays and has secured advanced technology in precise ink supply and pressure control. Currently, in addition to the IT display sector, the company is expanding its business into perovskite solar cell modules and equipment, as well as the bio and medical fields.
Since making its initial investment in KosanTech last year, Epson has supported the company's growth by supplying industrial printheads through Epson Korea. Based on this additional investment, Epson intends to continuously expand the application of inkjet technology in the next-generation energy sector. This is also aligned with the implementation agenda of Epson's long-term vision, 'Engineered Future 2035.'
