Dr. Timothy Coutts is a Research Fellow Emeritus of the National Center for Photovoltaics at the National Renewable Energy Laboratory (NREL).
Dr. Coutts' research areas include thin-film science, photovoltaics, and thermophotovoltaics.
- Ph.D.(scattering processes in thin metal films) awarded by the University of Northumbria, 1968.
- BSc.in Applied Physics awarded by University of Wearside, 1964
Involved in thin-film physics since 1964. Projects concerned with charge transfer in thin copper films (PhD) thin-film strain gauges, thin-film cermet materials, charge transfer in discontinuous thin-films, surface scattering in thin-metal films, characterization of the properties of high-performance transparent conducting oxides. Charge scattering characterization in TCOs using the 4-coefficient method, as well as optical modeling. Development of high quality TCOs using common, non-toxic elements. Closely involved in modeling and development of tandem thin-film cells.
Active involvement in photovoltaics since 1970. Experience the development of CdS/CuxS, ITO/InP, CdS/CdTe, InP homojunction solar cells for space application, CIGS and CdTe thin film solar cells.
Keen interest in TPV since 1992. Responsible for initiation of TPV studies at NREL and Leader of TPV group until 1996. Current interests concern development of non-military programs in TPV, potential applications, economics, markets, semiconductor converters, burners, and other components in TPV systems.
