Photosynthetic microorganisms, including algae and cyanobacteria, can export electrons/reducing equivalents upon illumination in a phenomenon called ‘exoelectrogenesis’. Biophotovoltaic systems (BPVs) are devices in which exoelectrogenesis of photosynthetic microorganisms can be harnessed to convert solar energy and water into electricity. Substantial efforts are underway to increase BPV outputs by, for example, optimising the electrode design and manufacture. However, further rational optimisation of the biological materials used in BPVs is being held back by limited understanding of the biological mechanism of exoelectrogenesis in photosynthetic microorganisms. My research aims to elucidate this mechanism using a suite of molecular biology and biophysics techniques. Further, analysis of the exoelectrogenic activity of biofilms using photoelectrochemistry can provide insight into the photosynthetic electron transfer reactions inside the cells, including the role of electron sinks.
