Development of ITO Transparent Electrode Patterning Technology Using Printing Techniques

Komori Corporation has announced the development of a high-definition patterning technology for ITO (indium tin oxide) transparent electrodes utilizing printing techniques, through joint research with the Flexible Electronics Research Group at Yamagata University.

ITO transparent electrodes are core components of solar cells. This technology enables the formation of high-definition electrode patterns without relying on conventional, high-cost methods. The technology will be exhibited at the Yamagata University booth (East Hall 7, 7E-16) at JPCA Show 2026, held at Tokyo Big Sight from June 10 to June 12, 2026.

Building on the printing technology cultivated over many years in offset printing presses, the KOMORI Group is expanding into the field of Printed Electronics (PE). In 2025, the company announced progress in the development of thin-film coating technology for perovskite solar cells and has been working to establish mass production technology for next-generation solar cells via printing processes. With the development of this new printing-based method for the ITO electrode patterning process, the company has moved one step closer to achieving solar cell manufacturing through an integrated printing process.

Conventionally, patterning of ITO transparent electrodes has required multi-stage or high-equipment-cost methods such as laser scribing and photolithography. This new technology replaces these methods with a printing process to pattern ITO transparent electrodes with high precision. Supporting the printing process of this technology is the expertise of Seria Corporation, a subsidiary of KOMORI. The company is advancing development with an eye toward deployment in integrated production lines for next-generation solar cells, including perovskite solar cells and organic photovoltaics (OPV).
