In the solar cell must have to do is platform? laptop battery Georgia Institute of Technology (Georgia Tech), researchers have developed a new technology may become a long and thin fiber-like solar cells.
In dye sensitized solar cells (dye-sensitized solar cell) and the combination of fiber optics and cable enclosure, Georgia Institute of Technology researchers have demonstrated a thin, soft solar cells, and its effectiveness is seen as achieving the same material flat solar cells on six occasions.
“We will deal directly with the end of the fiber of the sun; Professor Zhong Lin Wang Georgia Institute of Technology, said:” In the fiber placement next to an external load (external load) links with the electrode, you can cash generated by the load. “Wang is a researcher at the School and Benjamin Weintraub Yaguang Wei completed the study.
Dye-sensitized solar cell was invented in the 1990s is a film like solar energy program is different from the application of expensive materials for solar cell silicon semiconductor to generate electricity, dye cell sensitized solar is surrounded by a metal film of electrolyte in the oxidation of zinc nanowire (nanowire) using cheap dye molecules (dye molecules) film. When the sun shine a light on the cells in the dye molecules, they shot the electronics, metal film, sony vgp-bps9a/b battery and sent to external electrodes.
Traditional solar panels luck, a little problem is the incident photon can be degraded by heat, before the excited electrons in the metal, but on the contrary, the fiber allows the photons to have more opportunities and the active layer (active layer ) interactions. Wang has built a prototype is to use the 20-cm-long optical fiber to ensure that the length of the maximum amount of photons absorbed.
This technique can cut collect sunlight-edge optical fiber, then down the light in fiber optics, and developed a new version of the future may use a metal outer sheath transparent so that light from the inside with outside. The researchers also plan to manufacture sub-systems in a bundle that contains hundreds of parallel fiber-optic cable.
The research team is also considering this new type of solar cell efficiency of energy conversion from the current 3.3% to 8%, much of the marketing. Wang said he intended to use less material cost, low cost fiber optics to conduct experiments, and the use of titanium dioxide, zinc oxide instead of continuing to improve efficiency. In practice, such a solar cell allows product designers to develop new forms of commercial or military applications, fiber solar cells can be incorporated in equipment used to supply.
