Perfecting A Solar Cell By Adding Imperfections

Courtesy ScienceDaily  Tue, 06/17/2008 - 19:15

Nanotechnology is paving the way toward improved solar cells. New research shows that a film of carbon nanotubes may be able to replace two of the layers normally used in a solar cell, with improved performance at a lower cost.

Researchers have found a surprising way to give the nanotubes the properties they need: add defects. Currently, these solar cells, called dye-sensitized solar cells, have a transparent film made of an oxide that is applied to glass and conducts electricity....
