RESEARCH OVERVIEW

Biofuel Cells

Microbial fuel cells (MFCs) are emerging as promising green energy systems that utilize microorganisms to generate electricity by oxidation of organic substrates during the metabolic processes. The microorganisms can extract chemical energy from the substrate and convert it into electricity in the forms of electrons and protons along with some valuable byproducts such as gaseous fuels like hydrogen and methane.


Dye-sensitized solar cells (DSSCs) has attracted increasing attention due to the advantages of low-cost fabrication and simple production processes compared with the conventional silicon and thin-film solar cells. Generally, a DSSC consists of three components:  dye-sensitized photoanode made of photoresponsive semiconductor (TiO2) and dye sensitizer, redox electrolyte made of redox couple (I-/I3-), and catalytic counter electrode (Pt).
