Seiko Epson Corporation (Epson) and Epson X Investment Corporation have recently invested in Gosan Tech Co., Ltd. through a joint fund, the EP-GB L.P. Gosan Tech is a South Korean startup with inkjet technology that can be used in a variety of industrial fields.
Founded in 2015, Gosan Tech has developed and sells inkjet systems for fabricating organic light-emitting diode (OLED) displays. 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.
Perovskite solar cells are attracting attention as a next-generation renewable energy source and candidate to replace today’s silicon-based solar cells. They are lightweight, thin, and flexible, and the cost of fabricating them can potentially be reduced by utilizing production technologies such as inkjet printing. Moreover, significant improvements in power generation efficiency have been made in recent years thanks to active research and development.
Gosan Tech develops and markets perovskite solar cell modules and inkjet systems for their fabrication. These systems use inkjet technology to improve power generation, design, and material utilization by enabling thickness, material, and design modulation as well as thin-film quality.
As a partner, Epson will supply Gosan Tech with reliable and precise printheads suitable for industrial applications and will support Gosan Tech’s business growth in cooperation with its sales and service site, Epson Korea Co. Ltd.
This investment is aimed at expanding Epson’s inkjet technology into diverse applications in areas where new needs are emerging, such as electronics, biotechnology, and perovskite solar cells. Ultimately, the goal is to advance the frontiers of industry and achieve a sustainable society, Epson explained.
