Electrodes Deposited in the Presence of Phthalocyanines

The sensitization of such films were smdied in detail by photocurrent spectra, time-resolved photocurrent measurements, and intensity-modulated photocurrent spectroscopy Visible light absorbed in the dyes led to the 

Clearly improved electrode characteristics were obtained when the ZnO was prepared in a separate reaction step in the presence of a more favorable structuredirecting agent before the phthalocyanine chromophores were adsorbed in a subsequent step . Films of ZnO with a high porosity at preserved crystallinity were obtained in the presence of Eosin Since Eosin Y could be desorbed
