摘要

Contributions to the improvement of TiO2 photoelectrodes are presented. When using as underlying layer a thin film obtained by microwave-activated chemical bath deposition (MW-CBD), photoelectrodes with a two-layer TiO2 structure supersede the one-layer structure. This is explained on the basis of TiO2-conducting oxide contact. Also, the TiO2 sensitization issue is considered. A new simple way to sensitize TiO2 with copper oxide is used. This technology is perspective for trying to eliminate liquid electrolyte in DSSC and possibly, for water photolysis. Photoelectrodes formed with a copper oxide-porous TiO2 heterostructure work in the visible part of the spectrum and require no bias for photocurrent generation. Photovoltaic behavior is characterized by the spectral photocurrent dependence and time response. (c) 2005 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
