Abstract
The photo-response threshold of the Ag-NP/TiO2 composite thin films was enhanced and shifted into the visible and near-infrared when the chlorophyll dye extracted from mopane (Colophospermum mopane) leaves was adsorbed onto them. This allows the fabrication of a new generation of photocathodic p-DSSCs with previously unheard of unprecedentedly high concentrations of Ag (up to 80 mol%) evenly scattered in a TiO2 matrix, and this efficacy is the highest ever reported for a p-type working Ag/TiO2/chlorophyll/iodine electrode. This may enable the use of this electrode as a component of photo-sensitizer tandem devices. Read the article here: https://onlinelibrary.wiley.com/doi/full/10.1002/appl.202300044.
