Title:
NANO ENGINEERED PHOTO ELECTRODE FOR PHOTOELECTROCHEMICAL, PHOTOVOLTAIC AND SENSOR APPLICATIONS
Document Type and Number:
WIPO Patent Application WO/2009/002424
Kind Code:
A3
Abstract:
A unit nano photo cell comprised of a first component of conductive or semi conductive crystalline material, forming a backbone which spreads out in a three dimensional structural fashion, a second component of at least one photo active material bound to the first component, and a third component of carrier mobility promoter material bound to the second component, all of which together constitute a framework for separating electrons from holes when a light source is provide to the unit nano photo cell such that the second component acts as a photo active center, converting incoming photons into pairs of electron-holes, the first component transports electrons from the second component to a common bottom plate, and the third component extracts the holes from the second component and discharges them via a conductive pathway to a common top plate.
