“…This approach in testing photocatalytic systems with MV 2+ has been used previously, since it was reported that the presence of MV 2+ can enhance the electron withdrawal from photo-excited PSI. 59,60 A recent study has proposed that this is probably caused by a first reaction of oxygen with MV 2+ , which then oxidizes the reduced F B cluster of PSI. 61 This would also agree with our experiments since in the absence of oxygen, MV 2+ additions have no effect on the photo- current.…”

The engineering of renewable and sustainable protein-based light-to-energy converting systems is an emerging field of research. Here, we report on the development of supramolecular light-harvesting electrodes, consisting of the redox protein cytochrome c working as a molecular scaffold as well as a conductive wiring network and photosystem I as a photo-functional matrix element. Both proteins form complexes in solution, which in turn can be adsorbed on thiol-modified gold electrodes through a self-assembly mechanism. To overcome the limited stability of self-grown assemblies, DNA, a natural polyelectrolyte, is used as a further building block for the construction of a photo-active 3D architecture. DNA acts as a structural matrix element holding larger protein amounts and thus remarkably improving the maximum photocurrent and electrode stability. On investigating the photophysical properties, this system demonstrates that effective electron pathways have been created.
