This mean breaking through the theoretical limit of 10% efficiency (the Shockley-Quiesser limit) and creating solar cells that offer cost-effective clean energy. Scientists up to this point have struggled with truly understanding the materials that make up […]

Our main energy sources remain much the same as they were back then, fossil fuels, including coal and petroleum. While some […]
