Komori Corporation (Sumida-ku, Tokyo; President and CEO: Satoshi Mochida) is pleased
to announce that it has developed 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 booth (East Hall 7, Booth 7E-16) during the JPCA Show 2026, held at Tokyo Big Sight from Wednesday, June 10 to Friday, June 12, 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.
