There is growing interest in immobilizing oxygenic photosynthetic microorganisms, such as algae and cyanobacteria, onto electrodes to convert solar energy to electricity. This process forms the basis of biophotovoltaics (BPV)[1].  Previous research has revealed that bio-photoelectrochemical output can be significantly influenced by the structure of electrode, which act as electron collector for the biocatalysts. The state-of-the-art electrode architecture design for bio-photoelectrochemistry is microporous inverse opal structures made from indium tin oxide (IO-ITO), which is fabricated using templated synthesis.   Here, we aim to use additive manufacturing techniques (aerosol jet spraying) to design 3D electrodes for bio-photoelectrochemical systems such as BPVs.
