The bilayer lipid membrane (BLM) system containing metallo‐porphyrins (M‐TPP) and dyes as photosensitizers and electron mediators was studied. Cyclic voltammetry was used to determine photoconductivity and photo‐emf of the system. The largest photoconductivity was observed for the Mg‐TPP containing BLM with methyl viologen (MV 2+ ) and iodine (I 2 ) present in the aqueous solution. Photoactive dyes, due to their redox ability caused photovoltage up to 30 mV to develop, but no conductance change was observed under illumination in absence of Mg‐TPP. The relevance of cyclic voltammetry to the photoconductance and the photo‐emf observed in the BLM is discussed.
