Batteries included - a solar cell that stores power

Here, scanning electron microscope images show the solution: nanometer-sized rods of titanium dioxide (larger image) which cover the surface of a piece of titanium gauze (inset). The holes in the gauze are approximately 200 micrometers across, allowing air to enter the battery while the rods gather light.

Is it a solar cell? Or a rechargeable battery? Actually, the patent-pending device invented at The Ohio State University is both: the world’s first solar battery. Researchers report that they’ve succeeded in combining a battery and a solar cell into one hybrid device. Key to the innovation is
