Dr. Billy J. Stanbery, President and CEO, HelioVolt Corporation, 8/24/05


Download Podcast

Dr. Billy J. Stanbery founded HelioVolt Corporation in order to develop and market new technology for applying thin-film photovoltaic coatings to conventional construction materials. He invented the company's FAAST (TM) process, a low-cost, flexible manufacturing process for CIGS synthesis.

Dr. Billy J. Stanbery's early work in photovoltaics began in 1978, as a Senior Microelectronics Engineer with the Electronics Support Division of the Boeing Aerospace Company. His initial responsibility was the development of fabrication processes for very high power silicon concentrator solar cells for a Boeing IR&D program in 1978. Based on that work, he negotiated a contract with Sandia National Laboratories for further development of the technology in 1980, and was responsible during the contract period for the design and operation of an advanced computer controlled concentrator solar cell test facility.

Subsequent to the work on concentrator cells, Dr. Stanbery served as a consultant at Boeing on an Air Force SMATH V subcontract for the development of metallization systems and device configurations for fabricating silicon solar cells capable of withstanding high temperature heat treatment. Since 1982, he has participated in Boeing's development of large-area CuInSe2 solar cells and related photovoltaic devices, has published over two dozen papers, and holds seven U.S. patents in photovoltaic technology.

In 1988, Dr. Stanbery was named Senior Principal Engineer at Boeing, managing the company's terrestrial photovoltaic program, including three contracts with the National Renewable Energy Laboratory (NREL). His team set what was at the time the record for CIGS thin-film efficiency (14.6% AM1.5G). In 1990, a team lead by Dr. Stanbery demonstrated a tandem GaAs/CuInSe cell (measured at 25.8% AM1.5G), which still holds the world-record for thin-film solar cell efficiency.

Patrick J. Carr, ITT's Deep Space Network Operations and Maintenance Contract Program Manager, 9/7/05


Download Podcast

Patrick J. Carr is responsible for providing operations and maintenance support for the Deep Space Network, which supports JPL-NASA critical space exploration missions. The Deep Space Network's international system of antennas communicates with interplanetary spacecraft missions, such as Cassini and Mars Spirit. The network also collects information from Voyager 1, launched in 1977 and the most distant man-made object in space.

ITT's Systems Division makes sure the antennas at the Goldstone Deep Space Communications Complex in California are calibrated and positioned correctly to collect information from deep-space craft. The antennas at Goldstone range in diameter from 85 feet to 230 feet. Signals received from Cassini can be as weak as a billionth of a milliwatt, more than 20 billion times less than the power required for a digital watch.

Mr. Carr has over 33 years experience in the Aerospace and Defense industry, including assignments at the Pentagon and key U.S. satellite command and control, early warning, ICBM, and launch facilities around the United States.

Professor Yaneer Bar-Yam is the founding President of the New England Complex Systems Institute (NECSI), an independent nonprofit educational and research institution dedicated to advancing the study of complex systems. NECSI was established as a collaboration of faculty from Harvard, MIT, Boston University, Brandeis, and other academic institutions. In his research, Professor Bar-Yam has contributed to both physics and complex systems. On the technical side, he developed multiscale analysis, representations, and modeling, and contributed to the fundamental concepts of evolution and understanding the structure and dynamics of networks. He has also used complex systems concepts to advance a variety of diverse fields including the understanding of genetic regulatory networks, conservation biology, and systems engineering.

Professor Bar-Yam has lectured at and advised numerous corporations and government agencies, Raytheon, Lockheed Martin, Boeing, the World Bank, the Centers for Disease Control and Prevention, and the U.S. Military, the Department of Defense, and the intelligence community. His most recent research has applied complex systems ideas to complex problems facing companies and societal networks. He has developed the understanding of how the structure, processes, and information flow of organizations can be designed to meet challenges at all scales.

Professor Bar-Yam is the author of two books and over 150 articles in professional journals. His newest book, Making Things Work, explains how the basic concepts of complexity theory can solve complex problems in healthcare, education, international development, ethnic violence, and terrorism.

NECSI is an independent educational and research institution dedicated to advancing the study of complex systems. Complex systems have multiple interacting components whose collective behavior cannot be simply inferred from the behavior of components. The recognition that understanding the parts cannot explain collective behavior has led to various new concepts and methodologies that are affecting all fields of science and engineering, and are being applied to technology, business, and even social policy.
