Effects On Neutral Carbon Source Microbial Solar Cells Using Cyanobacteria As Exoelectrogens

Abstract
Microbial solar cells (MSCs) have drawn significant research interests in recent years. The principle of MSCs is different from of the common microbial fuel cells (MFCs), which use organic compounds as fuel to produce electricity. MSCs convert sunlight into electricity through oxygenic photosynthesis by phototrophic microorganisms such as cyanobacteria or algae without providing organic compounds. However, even though it had been proved that cyanobacteria have ability of power generation, yet the mechanism of producing electricity is still ambiguous. The purpose of this study is to investigate several factors that possibly affect MSCs performance. Results show that pH, light intensity, and ion concentration affected MSCs performance. Besides these, oxygen concentration affected system performance significantly but can be controlled by chemical addition. For future studies, these factors should be optimized to maintain system performance. Index Terms�Cyanobacteria, electricity, microbial solar cells, phototrophic microorganisms
