MIT makes solar-cell technology go viral. Literally

Researchers at MIT have genetically modified a virus that helps carbon nanotubes self-assemble along solar cells to improve efficiency of electron collection. The virus, called M13, helps to separate the two types of nanotubes - those that enhance solar cell performance and those that inhibit it.

According to Engadget, "Adding virus-built structures to dye-sensitized solar cells increased power conversion efficiency by almost one-third and, with only one additional step in the manufacturing process required, the new approach could be rapidly taken up by existing production facilities. MIT: proving once again that viruses are good for more than just smiting your enemies."
