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.
