Follow-on investment after first-round funding in 2025… Expanding capital and technology collaboration through the “EP-GB Fund” Targeting mass-production processes for perovskite solar cells based on OLED equipment technology
Domestic industrial inkjet solution specialist Gosantech Co., Ltd. announced that it has attracted additional investment from global precision equipment company Seiko Epson.
According to Gosantech, Epson made an initial investment in April 2025 and recently carried out a follow-up investment. This round was executed through the “EP-GB Investment Limited Partnership,” jointly established by Epson X Investment and Global Brain, and the specific investment amount was not disclosed in accordance with mutual agreement between the two companies.
Based on this investment, the two companies plan to expand the supply of high-precision, high-reliability industrial printheads as well as technology development and business collaboration with Epson Korea.
Industry observers view this additional investment, following the first round in 2025, as more than simple financial funding. It is seen as a case in which the competitiveness of a domestic technology company in precision processing has received positive recognition in the global market.
Founded in 2015, Gosantech is an inkjet solution company that has accumulated micro-droplet and precise pressure-control technologies in the OLED display manufacturing equipment sector. More recently, it has been expanding its business scope into manufacturing processes for perovskite solar cells (PSC), which are drawing attention as next-generation solar cells.
Gosantech’s proprietary inkjet-based perovskite module manufacturing system is characterized by dispensing materials only where needed, improving material utilization efficiency and forming uniform thin films. This is regarded as one of the core technologies for mass production processes of building-integrated photovoltaics (BIPV) and automotive solar cells.
A Gosantech official said, “This additional investment will further strengthen strategic and technological collaboration with Epson,” adding, “Based on precision inkjet technology, the company will secure global competitiveness in various advanced industrial sectors, including next-generation solar cells, bio, and medical devices.”
