TOKYO | Japan – November 2025 – Seiko Epson Corporation (TSE: 6724) has unveiled the S3200-S1, a new industrial inkjet printhead engineered for compatibility with strong solvents and designed to advance mass-production applications, including perovskite solar cell fabrication.
The S3200-S1 expands Epson’s PrecisionCore lineup with a wider print width, higher resolution, and robust solvent resistance. Its ability to jet materials such as NMP, DMSO, DMF, and DMI makes it well-suited for forming multiple functional layers in next-generation solar cell structures.
Key Features
-
Strong solvent compatibility supports advanced applications including multi-layer perovskite solar cell production.
-
4.73-inch print width—significantly wider than the existing 1.33-inch S800-S1—reduces the number of required printheads and simplifies system architecture.
-
High-resolution 600 dpi output delivers uniform thin-film coatings for consistent production quality.
-
Builds on the proven performance of Epson’s S800-S1 and I3200-S1HD, widely used in industrial thin-film and solar cell applications.
Industry adoption is already underway. Gosan Tech Co., Ltd. in South Korea is testing Epson’s strong solvent-compatible printheads for perovskite mass-production lines.
Kim Kwangsoo, President of Gosan Tech, commented: “We believe inkjet printing will play a central role in commercializing perovskite solar cells. Epson’s PrecisionCore printheads provide the durability, stability, and precise thin-film deposition needed to drive innovation in this field.”
The global perovskite solar market is projected to reach ¥2.4 trillion by 2040, and Epson’s S3200-S1 aims to support R&D through full-scale manufacturing with advanced inkjet solutions.
