Enhanced photocurrents via redox modulation by fluoride binding to oxoporphyrinogen in a zinc porphyrin-oxoporphyrinogen surface modified TiO 2 supramolecular solar cell

Abstract

A novel approach for improving photocurrent in a supramolecular solar cell, composed of zinc porphyrin-oxoporphyrinogen (ZnP-OxP) surface-modified TiO 2, by redox tuning through fluoride anion binding to the redox active host, OxP is demonstrated. © 2011 The Royal Society of Chemistry.
