Academic interests

An experimental material scientist with an interest in renewable energy in general and solar cells specifically. My main expertise is within thin film deposition and electrical, structural and optical characterization of thin films. Currently working on discovery and design of new, sustainable, materials suited for use in tandem solar cells.
