Improvement of the performance of a hydroxyaluminum phthalocyanine photoelectrochemical cell by a phthalic acid treatment

Effects of a phthalic acid treatment on the performance of hydroxyaluminum phthalocyanine (PcAlOH) photoelectrochemical cells have been investigated. PcAlOH thin films have been prepared by vacuum deposition on tin oxide substrates. The acid treatment induces a dimorphic transformation of the -form...

Zusammenfassung:	Effects of a phthalic acid treatment on the performance of hydroxyaluminum phthalocyanine (PcAlOH) photoelectrochemical cells have been investigated. PcAlOH thin films have been prepared by vacuum deposition on tin oxide substrates. The acid treatment induces a dimorphic transformation of the -form PcAlOH to a new polymorph n-PcAlOH absorbing on a larger range (550-900 nm). Photoelectrochemical studies with BQ/HQ and I/sub 3//sup -//I/sup -/ redox couples showed that the phthalic acid treatment improved strongly the performance of PcAlOH cells.
