Cheap Nano Solar Cells
March 5, 2007 | Source: Technology Review
Researchers at University of Notre Dame have demonstrated a way to significantly improve the efficiency of solar cells by adding single-walled carbon nanotubes to a film made of titanium-dioxide nanoparticles.
The method doubles the efficiency of converting ultraviolet light into electrons when compared with the performance of the nanoparticles alone. The solar cells could be used to make hydrogen for fuel cells directly from water or for producing electricity.
