Dr. Zhe Cheng has worked in the area of advanced metallization materials for silicon solar cells at the Central Research & Development department of E. I. du Pont de Nemours and Company (DuPont) in Wilmington, Delaware.
Dr. Cheng’s expertise is in the design, synthesis, processing, and characterizations of advanced functional ceramic and ceramic-metal hybrid materials for solid-state energy conversion. During his Ph.D. study, he revealed the fundamental behaviors and underlying mechanism for sulfur poisoning of solid oxide fuel cells using a combination of advanced experimental and theoretical tools.
In addition, he developed multiple sulfur-tolerant anode materials, which eventually led to the discovery of a new class of SOFC materials combining high electrochemical performance with significantly improved sulfur and coking tolerance. Dr. Cheng’s current research focuses are on advanced ceramic electrode and electrolyte materials for solid-state electrochemical energy conversion including solid oxide fuel cells, advanced ceramic materials and processing for electronic applications including photovoltaics (solar cells), and continued development of advanced high-temperature in situ characterizations tools for materials research.
