Dr. Perkins currently is a senior scientist in NREL’s Interfacial and Surface Science group, where he works with photovoltaic and energy materials. The group operates a unique cluster tool based on a physically integrated suite of deposition, surface modification, and analytical instruments. The tool includes two molecular beam epitaxy systems, two photoemission systems, a field-emission scanning Auger microprobe, a glovebox, a setup for low-current, low-energy electron diffraction, and a variable-temperature scanning probe microscope. Because of recent studies indicating the importance of photovoltaic module soiling by atmospheric dust, Dr. Perkins has become interested in understanding adhesion between particulate matter and surfaces representative of photovoltaic modules.
Dr. Perkins’ research interests are the physics and chemistry of multinary compound surfaces as they relate to photovoltaics, energy, and environmental sciences, including:
- surface chemical reactions
- electronic structure
- hybrid organic-inorganic materials
- interface engineering
- metal chalcogenides
- self-assembled monolayers
- two-dimensional materials
- single crystals
- model systems.
