Abstract

We show how the enzymatic polymerization of tyrosine with tyrosinase can be exploited for the immobilization of the light harvesting protein C-phycocyanin on the surface of hematite. This results in the in situ formation of the organic semiconductor melanin which stabilizes the protein strains on the semiconductor surface and increases the photocurrent by a factor of two in environmentally benign conditions. The PC-melanin coating on the hematite exhibits a selfsimilar, comb-like fractal pattern, pointing to the possibility to control the orientation of the chromophore for optimal light harvesting. Operating this bio-hybrid photoelectrochemical cell in environmentally benign environment could extend its lifetime compared with those used in strongly alkaline electrolyte and enhance the acceptance of the PEC cells in the society.
