Titania Nanotubes for Efficient Solar Cells.

The article reports that researchers at the Pennsylvania State University in University Park, Pennsylvania are considering titania nanotubes to replace the particulate coatings in dye-sensitive solar cells. The researchers believe that a 15 percent conversion rate of solar energy to electricity is achievable. The process used turns the opaque coating of titanium into a transparent coating of nanotubes, and the array is coated in a commercially available dye.
