Quantum dots to reduce heat loss in PV cells

By / June 21, 2010

In a recent post at ScientificAmerican.com, David Bielo details many of the inefficiencies of photovoltaic cells. Although layered cells composed of various elements can convert more than 40 percent of sunlight into electricity, more simple semiconducting materials such as silicon hover around 20 percent when mass-produced. And, at best, such cells could convert only a…
