Imagine a world where every window-laden skyscraper generates its own solar power, where the skylights in your ceiling are a source of light and electricity, and where your iPhone charges itself through the power of the sun. What could make this imagined world possible? Photovoltaic solar cells that are as transparent as regular glass. Our guest this week is Prof. Richard Lunt, the lead researcher on the MIT team that developed the technology, an assistant professor at Michigan State University, and co-founder of Ubiquitous Energy, the commercial enterprise through which this energy-capturing glassy-film will be distributed. Lunt talks about the science behind transparent luminescent solar concentrators and the opportunities ahead with applications ranging from power-generating car and building windows, to use on every device you can think of, from smart phones to store signs.
