Photoelectrochemical behavior of a hydroxyaluminum phthalocyanine polyvinylpyridine–iodine electrode

摘要

AbstractA complex of poly‐4‐vinylpyridine with iodine is formed when a thin film of the polymer is immersed in a I 3−/I−redox couple solution. A hydroxyaluminum phthalocyanine photoelectrochemical cell presents short‐circuit current up to 107.3 μA cm−2for a conversion efficiency of 0.035 when the organic film is coated with the polymer layer in an iodine/iodide electrolyte. This improvement is assigned to the contribution of the complex itself and to the decrease in the series resistan
