Abstract
Photoelectrochemical characteristics of a metal‐free phthalocyanine electrode prepared by a micelle disruption method are described. The novel technique is found to provide more photoactive phthalocyanine layers on indium tin oxide (ITO), compared with a vacuum sublimation technique. A short‐circuit photocurrent of 0.1 mA cm−2 is obtained for the ITO/H2 Pc(MD)/I−3 ‐I−/Pt cell under the white light illumination of 6 mW cm−2, together with an open‐circuit photovoltage of 70 mV and a fill factor of 0.42. These data lead to a value of 0.06% for the energy conversion efficiency.
