Light from the sun creates charges in an ultrathinfilm of carbon nanotubes (blue), which are extracted by fullerene C60 (brown) in this schematic of the groundbreaking proof-of-concept solar cell with greater than 1 percent efficiency.

In an approach that could challenge silicon as the predominant photovoltaic cell material, University of Wisconsin-Madison materials engineers have developed an inexpensive solar cell that exploits carbon nanotubes to absorb and convert energy from the sun.
