Two self assembled bilayer lipid membranes (BLM and C 60 contained BLM ) on indium tin oxide (ITO) were fabricated and their photoelectric conversion properties were studied. The investigation of the effects of applied voltage, donor and receptor on the photocurrent intensities showed that the anodic photocurrent of BLMs increased with increasing anodic potential and donor concentration; C 60 doped in BLM facilitated the photoinduced electron transfer across bilayer membranes. This novel self assembled ITO/BLM electrode can provide a simple and mechanically stable model for the study of the photoelectric properties of biomembranes.
