Fullerenes Enhance Self-Assembly and Electron Injection of Photosystem I in Biophotovoltaic Devices.

ABSTRACT: This paper describes the fabrication of microfluidic devices with a focus on controlling the orientation of photosystem I (PSI) complexes, which directly affects the performance of biophotovoltaic devices by maximizing the efficiency of the extraction of electron/hole pairs from the complexes. The surface chemistry of the electrode on which the complexes assemble plays a critical role in their orientation. We compared the degree of orientation on self-assembled monolayers of phenyl-C₆₁-butyric acid and a custom peptide on nanostructured gold electrodes. Biophotovoltaic devices fabricated with the C₆₁ fulleroid exhibit significantly improved performance and reproducibility compared to those utilizing the peptide, yielding a 1.6-fold increase in efficiency.
