Fundamental technologies for an electronic device which is implemented on a molecular scale by using electron transport proteins and/or their model Langmuir-Blodgett films are discussed. The study deals with the photoelectric properties of a molecular heterojunction using flavin-porphyrin Langmuir-Blodgett multilayers. The photocurrent revealed unexpectedly strong rectifying properties of the molecular heterojunction. At 300 K the rate of electron transfer from flavin to heme was faster by seven orders of magnitude than that from heme to flavin
