Photon Double Whammy: Careening electrons may rev up solar cells

By Peter Weiss, 15:50 PM April 15, 2008

In ordinary photovoltaic cells, lots of sunlight goes to waste as it heats up the cell. New results suggest that solar cells made from nanocrystals can trade this wasteful heating for an electricity-generating boost.

Theoretical calculations indicate that nanocrystal-based solar cells could convert 60 percent of sunlight into electricity, say Richard D. Schaller and Victor I. Klimov of Los Alamos (N.M.) National Laboratory. The best solar cells today operate at an efficiency of about 32 perce...
