Komori Corporation, a printing press system manufacturer, has announced development of a high-resolution patterning technology for Indium Tin Oxide (ITO) transparent electrodes using printing technology developed through joint research with the Yamagata University Research Group for Flexible Technologies.
ITO transparent electrodes are key components of solar cells, and this technology enables the development of highly precise electrode patterns without relying on conventional high-cost manufacturing methods. The technology was exhibited at the Yamagata University Stand during the JPCA Show 2026, held at Tokyo Big Sight from Wednesday, 10 to 12 June 2026.
Based on print technology cultivated through decades of offset printing press development, the Komori Group has been expanding its technological capabilities in the field of Printed Electronics (PE). In 2025, Komori announced progress in the development of thin-film coating technology for perovskite solar cells and has been working toward establishing mass-production technologies for next-generation solar cells through printing processes.
By developing a new printing-based approach for the patterning of ITO transparent electrodes, Komori has moved one step closer to realizing solar cell manufacturing through an integrated printing process.
Conventionally, ITO transparent electrode patterning has relied on methods such as laser scribing and photolithography, which involve multiple process steps or significant equipment investment. This technology is a new approach that enables the high-precision patterning of ITO transparent electrodes by replacing these conventional methods with a printing process. The printing process that supports this technology is based on expertise provided by Seria Corporation, a Komori subsidiary.
Looking ahead, Komori will continue development with a view toward applying this technology to the manufacturing of next-generation solar cells, including perovskite solar cells and organic photovoltaic (OPV) cells, and ultimately deploying it in integrated production lines.
