Green Revolution: Solar Power

Arizona gets plenty of sunlight, and researchers there are working hard to turn that energy into electricity we can use. At Arizona State University, graduate student Brad Brennan makes and tests new materials that will allow us to build smaller, cheaper, flexible photovoltaic solar cells that can go almost anywhere. Brittany Lynn, a student at the University of Arizona, has been testing solar cells with different surfaces to see how surface shape affects the energy production of the cells.
