Abstract

- Photoelectrochemical processes are described for epitaxial phthalocyanine thin films on SnS2 single crystal photoelectrodes. Square lattice formation is indicated during the nucleation of the ordered monolayers of the trivalent metal Pc's (e.g. InPc-CI) and the tetravalent metal Pc's (e.g. VOPc). Multilayer growth leads to packing structures which strongly red-shift (VOPc, InPc-CI) or blue-shift (AIPc-F) the Q-band photocurrent spectra, in accordance with established models for exciton coupling effects. Quantum yields for photocurrent production versus Pc coverage are consistent with the requirement for exciton diffusion from the point of excitation in the Pc multilayer to the SnS2 interface, where charge injection occurs.
