Flexible Solar Cells That Can Wrap Around A Pencil, Gwangju Institute Of Science And Technology Study
The idea of solar cells usually conjures the image of broad panels lying in the sun like scorched saltines. But in the latest probe into the physical limits of the technology, South Korean scientists have made solar cells thin and flexible enough to be wrapped around a pencil.
The new cells are more than 50 times thinner than human hairs and over 1,000 times thinner than most conventional solar cells. The cells were thinned down to the point where they could be wrapped around objects or fit the contours of unstructured materials like fabric.
