Yet another 3-D solar cell
A recent solar advancement out of Georgia Institute of Technology may be innovative, but it is by no means novel.
Researchers said they’ve come up with a three-dimensional photovoltaic system that could allow PV systems to be located other places besides rooftops. The technology uses zinc oxide nanostructures grown on optical fibers and coated with dye-sensitized solar cell materials.
The researchers said the technology enables PV generators to be foldable, concealed and mobile. According to Professor Zhong Lin Wang, optical fiber could conduct sunlight into a building’s walls, where the nanostructures would convert it to electricity.
