Claim Text:
1. A method for fabricating a high efficiency bio-photovoltaic cell using plasmonic metal nanoparticles and naturally extracted graminoids, comprising: a first process of extracting one of graminoids or chlorophylls from natural grasses; then, a second process of preparing metal nanoparticles selected from silver, gold, platinum or palladium, and a sheet type titanium dioxide electron acceptor, wherein the metal nanoparticles provide a surface plasmon effect; then, a third process of laminating the sheet type titanium dioxide electron acceptor, the silver nanoparticles and a naturally extracted photo sensitizer on a transparent electrode to prepare a photo-electrode; and then, a fourth process of preparing a platinum coated counter-electrode having platinum and injecting an electrolyte between the photo-electrode and the counter-electrode to complete a photovoltaic cell, wherein the inserted metal nanoparticles are coupled to a bio-photo sensitizer through an organic ligand material while exhibiting surface plasmon effect.
