The Holmes Research Group operates in the Department of Chemical Engineering and Materials Science under the direction of Prof. Russell J. Holmes. The group is primarily focused on the study of thin film organic and hybrid organic-inorganic materials and their application in a variety of electronic and optoelectronic devices.  As such, our specific efforts involve understanding materials processing, characterization of thin film light-matter interactions and optoelectronic behavior, and the performance of photovoltaic (solar cells) and light-emitting (OLED) devices.

Our ongoing work is supported by the Department of Energy, Meta, Microsoft, the National Science Foundation, and Ronald L. and Janet A. Christenson.
