Abstract In this thesis, three different bioinspired approaches have been introduced to build up vertically oriented SHJ photosystems. Firstly, the halogenated red zipper architecture was assembled from the anionic HH-NDI-OPE initiator and the cationic and anionic NBr-NDI-OPE propagators on a gold electrode. This zipper assembly generates high photocurrent and high efficiency. Secondly, the non-halogenated ON-NDI-OPE zipper assembly was introduced. Compared with the halogenated zipper less photocurrent and same critical thickness was observed. The lower photocurrent was attributed to the higher HOMO energy of the ON-NDI than the NBr-NDI. The third antiparallel redox gradients architecture generates approximately the same photocurrent and double critical thickness than the NBr-NDI-OPE zipper assembly.
