Old-fashioned.  Now out of date?: Solar cells have been around for decades, but with low-efficiency and high manufacturing costs, they have yet to be adapted into our everyday life.  Could new interdisciplinary research by the University of Minnesota make solar power more efficient and affordable?

This month University of Minnesota researchers have developed a technique to better capture solar energy using 'quantum dots,' a type of nanoparticle. Researcher William Tisdale said, while

“This work is a necessary but not sufficient step for building very high-efficiency solar cells. It provides a motivation for researchers to work on quantum dots and solar cells based on quantum dots.”

The technology could improve solar energy efficiency from 30 to 66 percent! That's incredible. Furthermore, the improvements may also cut manufacturing costs (and carbon footprints) by removing the need for high temperature processing. The ramifications for nanotechnology and clean energy abound.
