Ph.D., CHEMICAL ENGINEERING, 2010
SENIOR DEVELOPMENT SCIENTIST, PELLUCERE TECHNOLOGIES INC.

Seungyeol Han is a pioneering chemical engineer whose work bridges academic innovation and commercial impact. With over 15 years of experience in sol-gel chemistry, nanoparticle formulation, and scalable optical coatings, Han has helped redefine how advanced materials are deployed in real-world applications.

Han began his U.S. research journey in 2004 as a visiting scholar at ����Ӱ�� State University, later earning his Ph.D. in Chemical Engineering. His doctoral work focused on solution-processed oxide semiconductors and dielectric materials—research that laid the foundation for launching CSD Nano, a Corvallis-based startup co-founded during his time at OSU. There, Han led the development of MoreSun™, a sunlight-curable antireflective coating that boosts solar panel efficiency through field application, eliminating the need for factory processing. This breakthrough technology has been deployed across the U.S., Europe, and Asia.

As Chief Scientist, Han guided CSD Nano’s evolution into Pellucere Technologies, securing venture funding and spearheading strategic growth, including acquisitions in Arkansas and Germany and the establishment of a manufacturing facility in India. Now based in Springdale, Arkansas, Han continues to lead product development as a Senior Development Scientist, driving innovation in coatings for solar, automotive, and industrial applications.

“The development and commercialization of the MoreSun™ coating stands out as the most meaningful project of my career,” Han said. “Seeing solar panels across different continents benefit from something I helped create from scratch has been deeply rewarding.”

Han’s career reflects a deep commitment to collaborative problem-solving and entrepreneurial thinking. He remains closely connected to OSU’s College of Engineering, contributing to DOE Solar Prize projects and mentoring students through showcase events. His work has not only advanced the solar industry but also demonstrated how high-performance materials can be both scientifically rigorous and operationally practical.

“The OSU College of Engineering doesn’t just teach you how to solve problems, it teaches you how to see them in ways others don’t. It’s a place where innovation is encouraged, interdisciplinary thinking is normal, and ideas are supported all the way from conception to commercialization,” Han said. “On a personal level, OSU also became a second home, it gave me mentors, lifelong friends, and the clarity to pursue a meaningful career.”
