The Author is a world-renowned scientist, engineer and pioneer in Solar Energy, distinguished professor of Physics and Solar Energy of the University of Delaware, emeritus., fellow, AAAS, APS, ASES, IEEE. Author of 385 Journal articles and dozens of books in Semiconductor Science and Solar Energy, recent author of the theory of the new solar cell that does not use a pnjunction to separate the electrons from the holes that sunlight creates, but a thin layer of cadmium sulfide attached to the solar cell. He designed the Solar One House of the University of Delaware, the first systems house that has hybrid solar panels included in the roof-structure that convert sunlight into electric energy and heat and uses load leveling that is essential for power utilities to even out the fluctuating solar energy.
