ResumoAbstract— Photoelectrochemical behaviour of Chl‐ a multilayers, built up on SnO 2 optically transparent electrode by means of the Langmuir technique, was investigated in an electrolyte solution with or without hydroquinone as a reducing agent. Quantum efficiencies of the anodic photocurrents in the presence of hydroquinone tended to decrease with increasing number of layers. In the electrolyte without hydroquinone, the cathodic photocurrents were observed in the presence of dissolved oxygen. A possibility of a reaction of water with the oxidized Chl‐ a is suggested.
