WN@tL: “The Sun Is Ready to Make Your Electricity Greener and Cheaper in Wisconsin”

November 30 @ 7:00 pm - 8:00 pm

Speaker: Mike Arnold, Materials Science and Engineering

Description: The Earth is continuously bathing in over one-hundred-million-billion watts of sunlight. Photovoltaic solar cells can harvest this green energy and convert it into electricity. Over the last ten years, the price of solar electricity has plummeted, global installations have increased more than 10-fold, and solar is beginning to significantly penetrate into Wisconsin. This presentation will focus on the materials and composition of photovoltaic solar cells and the principles of their operation. It will discuss the history of photovoltaics, how efficiency has increased, and how price has dramatically decreased. Finally, the presentation will provide a forward-looking perspective at upcoming growth, challenges, and opportunities in photovoltaics and how solar electricity will fit into our future.

Bio: Michael Arnold is a Professor of Materials Science and Engineering at the University of Wisconsin-Madison. He earned a B.S. in Electrical and Computer Engineering at the University of Illinois, Urbana-Champaign before completing a Ph.D. in Materials Science and Engineering at Northwestern University. His research focuses on the development of new semiconductors for electronics and energy applications, with an emphasis on carbon-based nanomaterials such as semiconducting carbon nanotubes and graphene. In his free time, he enjoys tennis, mountain biking, running, eating Babcock Dairy quadruple scoops, and spending time with his partner and children.
