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 start-up with inkjet technology that can be used in a variety of industrial fields.
Inkjet printing has been found to be a great method for depositing quantum dots on solar cell substrates.
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;
- Environment, with inkjet systems for perovskite solar cells*; and
- Bio-medical, including drug deposition, tissue engineering and diagnostic
Sustainable Partnerships
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.
In the Epson 25 Renewed corporate vision, Epson has outlined its strategy for increasing productivity and advancing the frontiers of industry through various solutions using inkjet technology. Inkjet technology has the potential to dramatically reduce environmental impacts and realise a sustainable 
Epson will supply Gosan Tech with reliable and precise printheads suitable for industrial applications society.
Perovskite solar cells are attracting attention as a next-generation renewable energy source with potential 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 utilising production technologies such as inkjet printing. 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 utilisation by enabling thickness, material and design modulation as well as thin-film quality.
Epson’s investment in Gosan Tech is directly 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.
Future Impact
Going forward, Epson aims to achieve a sustainable society through co-creation with a variety of partners based on its proprietary technologies, products, and services.
In its printhead sales business, this means uncovering opportunities to create new markets with partners; and to this end, Epson is forming partnerships to enhance printhead sales and provision of solutions that include peripheral technology. By doing so, Epson aims to accelerate efforts to expand the ecosystem of inkjet technology applications not only in perovskite solar cells but also in new markets that will contribute to advancing the frontiers of industry and reducing environmental impact.
