New Look for Solar Cells

From Nanotechweb.org News:

Researchers in the US have shown that carbon nanotubes can significantly improve the efficiency of solar cells made of titanium dioxide, a readily available and cheap chemical routinely used in paint and sunscreen. Prashant Kamat and colleagues at the University of Notre Dame, Indiana, anchored titanium dioxide nanoparticles on single-walled carbon nanotubes and found that the efficiency of converting ultraviolet light into current was doubled compared to that using the nanoparticles alone.
