Researchers at Wake Forest University, Carolina, trying to make organic solar cells to be able to work better by using a layer of optical fiber bristles. An optical fiber called "Light Pipes" stamped on a polymer substrate that form the base of the cell.
Researchers today continue to increase the efficiency of organic solar cells up to 10 percent with a combination of organic chemistry to improve the performance of silicon cells. For apart from the problem of the missing sunlight through reflection, it is necessary to antireflective coating or etch the surface of the cell so that the photon absorption increases.
Light pipes that stand out like a coarse straw surrounded by thin organic solar cells are applied using a dip-coating process, light absorbing dye, and the polymer is sprayed into the cell.
The glass fiber cells tested in the laboratory showed increased absorption of light by the fiber up to half as well as twice as many watt-hours during the day compared with flat panels. This is due to fiber can accept light from various angles.
