✦ Synopsis

The photoelectric conversion and surface photovoltage spectrum of tetrasulfonated gallium phthalocyanine (GaTsPc) on a titanium dioxide (TiO 2 ) nanostructured electrode are reported. As a comparison, the surface photovoltage spectrum of the sublimed film of GaTsPc deposited on an indium tin oxide conducting glass held at 10 AE 0.1°C is also reported. The GaTsPc molecule exists mainly as a dimer on the nanostructured titanium dioxide electrode and in the sublimed film. The absorption of the GaTsPc dimer on the nanostructured titanium dioxide electrode does not convert into a photocurrent or a surface photovoltage while that of the GaTsPc dimer in the sublimed film contributes to the generation of a surface photovoltage, which is due to the different orientation of the GaTsPc molecule aggregation.
