EFFICIENT ORGANIC PHOTOVOLTIC DEVICES USING PHOTOACTIVE GRAPHENE OXIDE, ORGANIC LINKERS AND SEMICONDUCTOR NANOPARTICLES

摘要

The present invention provides an improved photovoltaic system based on Graphene/Graphene oxide with organic linkers and semiconductor nanoparticles and a method for preparation thereof. The role of organic linkers is absorption of more photons from the sun light, once they are attached to Graphene or reduced graphene Oxide (RGO) while the semiconductor nanoparticles not only open up the extra range for solar spectrum, but also increase the conductivity of the RGO or Functionalized graphene oxide sheet with different chemical-organic linkers. The photovoltaic system according to the present invention is inexpensive, eco-friendly and reliable in terms of response and efficiency.
