Wrapping Solar Cells around an Optical Fiber

Technology Review, OCT. 30, 2009

Researchers at Georgia Tech have made dye-sensitized solar cells with a much higher effective surface area by wrapping the cells around optical fibers.

These fiber solar cells are six times more efficient than a zinc oxide solar cell with the same surface area, and if they can be built using cheap polymer fibers, they shouldn't be significantly more expensive to make.
