Arizona is among places in the world that get the most sunlight. Surprisingly, however, the hotter than average heat from sunlight experienced in the state’s desert regions — like Phoenix — creates conditions that keep those areas from generating comparable amounts of solar power than what would be produced by sunlight in cooler environments. Nick Rolston, an assistant professor in the School of Electrical, Computer and Energy Engineering, part of the Fulton Schools, talks about research he and colleagues are doing to develop the next generation of energy materials and devices that might help generate more solar power from sunlight in hotter locales.
