John I. Yellott (October 25, 1908 – December 30, 1986) was a scientist internationally recognized as a pioneer in passive solar energy, and an inventor with many patents to his credit.
 In his honor the American Society of Mechanical Engineers (“ASME”) Solar Division confers a biannual "John I. Yellott Award" which "recognizes ASME members who have demonstrated sustained leadership within the Solar Energy Division, have a reputation for performing high-quality solar energy research and have made significant contributions to solar engineering through education, state or federal government service or in the private sector."
Monica Viviene Oliphant {'1': ", '2': ", '3': ", '4': "} (née Kammer ; born 4 August 1940 in Ilford) is a British–Australian research scientist, specialising in solar energy.
 She was President of the International Solar Energy Society from 2008 to 2009 and is an adjunct associate professor at the University of South Australia.
 She has a master's degree in physics from the University of London and worked for almost 20 years as an energy research scientist for the Electricity Trust of South Australia, but since 2000 has been an independent consultant specialising in residential energy efficiency and renewable energy.
 In 2002, Oliphant won the SA Great Environmental Award.
Garry Frederick Baverstock (born 1949) is an Australian Perth-based architect, property developer, author and scientist, specialising in energy efficient building design.
 He was one of the pioneers of sustainable architecture in Australia, championing passive solar design of buildings and the use of solar energy.
 The founder of Ecotect Architects in 1969, he is a professor and Built Environment Program Manager of the Research Institute of Sustainable Energy at Murdoch University in Perth.
 He became president of the International Solar Energy Society in Western Australia after holding the position of Honorary Secretary from 1979-1986.
 His work is primarily involved with solar energy design and promoting green urbanism.
 He has designed over 700 solar houses in all climates throughout Australia.
 Along with his wife Julia Hayes, he designed the eco-friendly Swanbourne Business Centre in Swanbourne.
The Argonne–Northwestern Solar Energy Research Center (ANSER Center) is a joint research program between the Argonne National Laboratory and Northwestern University.
 Michael R. Wasielewski, Professor of Chemistry at Northwestern founded the ANSER center in 2007 and is its current director.
 The center's goal is to develop the fundamental understanding, materials, and methods necessary to create efficient and economically viable technologies for solar fuels and electricity production.
 The union of synthesis, measurement, theory, and engineering allows ANSER to create exceptional new energy conversion systems.
 As part of its $777 million effort to establish Energy Frontier Research Centers, Grants provided by the US Department of Energy will enable the ANSER "to analyse photosynthesis for ways to create more efficient photovoltaic cells and create hybrid solar cells that have both organic and inorganic components."
The Fraunhofer Institute for Solar Energy Systems ISE (or Fraunhofer ISE) is an institute of the Fraunhofer-Gesellschaft.
 Located in Freiburg, Germany, The Institute performs applied scientific and engineering research and development for all areas of solar energy.
 Fraunhofer ISE has three external branches in Germany which carry out work on solar cell and semiconductor material development: the Laboratory and Service Center (LSC) in Gelsenkirchen, the Technology Center of Semiconductor Materials (THM) in Freiberg, and the Fraunhofer Center for Silicon Photovoltaics (CSP) in Halle.
 Since 2006, Prof. Dr. Eicke R. Weber is the director of Fraunhofer ISE.
 With over 1,100 employees, Fraunhofer ISE is the largest institute for applied solar energy research in Europe.
 The 2012 Operational Budget including investments is 74.3 million euro.
The Solar Energy Research Center (SERC) is a research center dedicated to identifying methods for converting solar energy to renewable fuel sources.
 SERC opened on 25 May 2015 at the Lawrence Berkeley National Laboratory (LBL) in Berkeley, California.
 SERC is housed at the newly opened Chu Hall, named for Stephen Chu.
The Institute of Energy Conversion (IEC), located at the University of Delaware is the oldest solar energy research institute in the world.
 It was established by Karl Boer in 1972 to pioneer research on thin film solar cells.
 The IEC performs independent research and collaborates with businesses alongside training undergraduate and graduate students in solar cell engineering.
 In 2011, the organization was the highest recipient of the United States Department of Energy's (DOE) SunShot Initiative and was awarded five grants totaling $9.1 million to research next generation solar cells to reduce the cost of solar cells by 75 percent by the end of the decade.
The SERI microalgae culture collection was a collection from the Department of Energy's Aquatic Species Program cataloged at the Solar Energy Research Institute located in Golden, Colorado.
 The Aquatic Species Program ended in 1996 after its funding was cut, at which point its microalgae collection was moved to the University of Hawaii.
 In 1998 the University of Hawaii, partnered with the University of California at Berkeley, received a grant from the National Science Foundation (NSF), for their proposal to develop commercial, medical, and industrial uses of microalgae, as well as new and more efficient techniques for cultivation.
 This grant was used to form Marine Bioproduct Engineering Center (MarBEC), a facility operating within the University system of Hawaii at Manoa, but connected to corporate interests.
The Ben-Gurion National Solar Energy Center at Midreshet Ben-Gurion is the national alternative energy research institute of Israel.
 It was established in 1987 by the Ministry of National Infrastructures to study promising alternative and clean energy technologies, particularly those involving solar power.
 Since July 1991 the Center has been operated by Ben-Gurion University of the Negev's Jacob Blaustein Institutes for Desert Research.
 Its director is David Faiman.
Golden is the Home Rule Municipality that is the county seat of Jefferson County, Colorado, United States.
 Golden lies along Clear Creek at the base of the Front Range of the Rocky Mountains.
 Founded during the Pike's Peak Gold Rush on 16 June 1859, the mining camp was originally named Golden City in honor of Thomas L. Golden.
 Golden City served as the capital of the provisional Territory of Jefferson from 1860 to 1861, and capital of the official Territory of Colorado from 1862 to 1867.
 In 1867, the territorial capital was moved about 12 mi east to Denver City.
 The United States Census Bureau estimates that the city population was 18,867 in 2010.
