Abstract: In this work, we inserted a PPy layer between the bR LB film and ITO electrode, and investigated the effect of PPy film on the photoelectric properties of LB films containing bR. It was found that the PPy film with a certain thickness, as a proton acceptor, could make bR LB film’s photocurrent increase 30%~50% in comparison with that of bR LB film.

Key words: bacteriorhodopsin, polypyrrole, photocurrent
