Our Green Energy lab is currently focused on the development of Microbial Fuel cells, Dye Sensitized solar cells and Micro fluidic biosensors. The lab aims at a strong interdisciplinary research by joining hands with the expertise from the fields of Physics, Chemistry, Biotechnology, Microbiology and Electrical Engineering

Microbial Fuel Cell (MFC) and Phototrophic Microbial Fuel Cell (PMFC)

MFC/PMFC employs the Microbes (in this case called as Exoelectrogens) as catalysts to convert chemical and photic energy resident in organic chemicals and sunlight to electrical energy.  The process is carbon neutral and sustainable and has potential to find wide applications in the future.  Apart from electricity generation an MFC/PMFC also can double up as a strategy for carbon sequestration and bioremediation.  The green energy lab will focus on the use of varied photrophic and heterotrophic microorganisms as exoelectrogens, design and fabrication of Microbial Fuel Cells of differential volumes, building prototypes that are amenable for scaleup and deployment, and devising MFC/PMFC based strategies for waste management and carbon sequestration. Works ongoing in the facility are,

1.Enterobacteriaceae based heterotrophic MFC with novel Proton Exchange Membrane (PEM)
2. Design, fabrication, optimization and operation of cyanobacteria based PMFC
3. Continous flow MFC for waste water treatment
4. Development of Microfluidic MFC and exploring its potential applications
5. Sediment MFC (SMFC) to treat wastes including human waste

Dye Sensitized solar cells (DSSC):

We explore the use of natural dyes obtained from both plants and microbes. The dye present in leaf, bark, buds, flowers, fruits or seeds are tailed for photovoltaic applications. Attempts are there to modify the photo-electrode, electrolyte and the counter electrode.

Quantum dot sensitized solar cells (QDSSC):

This constitutes one of the most promising approaches to third generation solar cells. Our plan is to optimize synthesis procedures for lead salt based nanostructures and heteronanostructures and then to fabricate the solar cell. 

Micro contact printing (μCP):

Using this technique we are printing DNA and biomolecules for different biological applications. The surface bound biomolecules find application in bio sensors, chromatography, diagnostic immune assays, cell culturing, expression studies and other analytical procedures.


Microfluidizer system belongs to microfluidic process which has been extensive proposed as a green alternative technology in miniaturization from macro to micro/nano structure dimensions. Here we are using this technology in different biological applications such as to make glucose biosensors, wound healing assays, fluidic capillaries for the evaluation of DNA.
