Abstract

The photoelectrochemical behavior of chlorophyll (alpha) and pheophytin (alpha) monolayers, deposited on SnO2 optically transparent electrodes by means of the Langmuir-Blodgett technique, has been investigated. Spectra of photocurrents coincided with the absorption spectra of photosynthetic pigment monolayers at the SnO2-solution interfaces. The anodic and cathodic photocurrents were measured at different electrode potentials. The effects of solution pH, electrode potentials and redox reagents on the conversion of solar energy in photocurrent by photosynthetic pigments in monolayers on optical transparent electrodes are discussed.
