Christian Gueymard
Country: United States
Year Started Research: 1973
Title of Research: Solar Radiation Modelling and Measurement for Advanced
Solar Resource Applications
University: Florida Solar Energy Center
Still Active in Research: Yes

Since starting solar-related research in 1973 as a graduate student, Christian Gueymard developed an internationally
recognized expertise in the fields of solar resource assessment, solar radiation modelling, radiometry, forecasting,
atmospheric remote sensing, and their applications to various types of solar energy systems. Some of the solar radiation
models he developed are being used widely by the international solar energy community. In particular, his SMARTS model
has been selected by ASTM and IEC to promulgate spectral irradiance standards needed for photovoltaic cells testing and
rating, among many other applications. Christian has been a Research Scientist at the Florida Solar Energy Center before
founding Solar Consulting Services. This company offers expert assistance to public and private institutions involved in
solar energy or building applications. He has been serving as Associate Editor of the Solar Energy journal since 2007,
and regularly serves as referee for various scientific journals, conferences or doctoral theses. He has been involved with
various technical committees for ASHRAE, ASTM, CIE, and the American Solar Energy Society. Christian has published
220+ scientific papers in refereed journals or conference proceedings, as well as 40+ research reports. He has received
three “best paper” awards so far and has contributed to various books, including “Modeling Solar Radiation at the Earth’s
Surface” (2008), “Solar Cells and their Applications” (2010), “Encyclopedia of Sustainability Science and Technology”
(2012), “Solar Energy” (2013), “High Concentrator Photovoltaics” (2015), and “Solar Resources Mapping” (2019). In
recent years, he has been involved in international projects, such as IEA-SHC Task 46 and IEA-PVPS Task 16, or Europe’s
DNIcast, all related to solar resource prediction or forecasting and continues to collaborate with many scientists around
the world, and to help students whenever possible. As of this writing (May 7, 2020), Google Scholar credits Christian with
11,531 total citations and a h-index of 51.

Subhendu Guha
Country: USA
Year Started Research: 1979
Area of Research: Amorphous silicon
University: TIFR, India; United Solar. MI, USA
Still Active in Research: Yes

Dr Subhendu Guha started his research on amorphous silicon material and solar cells at TIFR, Bombay in 1978.
Since 1982, he has worked in the same field at Energy Conversion Devices and United Solar Ovonic in MI, USA making
pioneering contributions. He has received many awards including World Technology Award, PVSEC Award, and Bright
Light Award from US Department of Energy. He became the President of United Solar in 2001 where he led a team that
showed consistently for a decade record solar cell efficiency using a-Si alloy technology. United Solar also emerged as the
world’s largest manufacturer.
