The photocurrent response in solid-state films of two different hemoproteins, horseradish peroxidaseand cytochrome c, was studied by employing a geometry of planar diode device. The highest occupiedmolecular orbital energy of the two solid-state hemoproteins was measured using photoelectron yieldspectroscopy. Results showed that the photocurrent response of hemoprotein films under white lightillumination was found extremely slow (ca. 160–480 s) owing to the charge blocking by insulatingsurrounding parts of which size resulted in largely different photocurrent time scale between the twohemoprotein films.
