Abstract:
1. An optoelectronic device comprising a first electrode, a second electrode, and at least one layer of photoactive nanoparticles interposed between said first electrode and said second electrode, wherein at least one of said first electrode and said second electrode is light transmissive, and wherein said photoactive nanoparticles comprise conducting solid surfaces which are attached to a photosystem I (PSI) units of a photosynthetic organism, wherein said PSI unit comprises at least one cysteine substitution mutation, said cysteine substitution mutation mediating covalent attachment of said PS-I unit to said conducting solid surfaces and further said cysteine mutation being on an extra-membrane loop of said PSI unit and in a proximity to a reaction center of said PS-I unit such that an electric junction is generated between said reaction center and said solid surface, said PS-I unit maintaining a photocatalytic activity when attached to said solid surface.
