Bacteriorhodopsin (BR) is a light-transducing protein contained in a purple membrane of microorganism Halobacterium salinarium. Natural function of BR is to act as a light-driven proton pump in energy balancing mechanism of the bacterium. Numerous technical applications of BR that use proton pumping have been proposed [11]. A thin ?lm of oriented BR enclosed between two electrodes generates a temporal photovoltage response when illuminated [13]. The intensity of photoresponse depends on intensity and spectral power distribution of illuminating light. This work describes a model of wavelength dependency of photoresponse of elements containing a thin ?lm of wild form of BR and its reconstituents and compares the model to experimentally measured values.
