Courses offered

  • Fluid Mechanics
  • Heat and Mass Transfer

Solar Energy
We are interested to explore and augment the current understanding of the photovoltaic devices, such as Silicon solar cell and Dye-Sensitized solar cell, with the final goal of increasing their overall efficiencies. A photovoltaic device is basically a multi-layered structure comprised of the p-n junction, transparent electrodes, metallic contacts, anti-reflection coating, and packaging materials. The competency of a solar technology is evaluated on the basis of the operating efficiency per unit currency spent, hence there is always a push to lower the cost and enhance the efficiency to make the solar technology more economically competitive. We are interested to reduce the optical, electrical and thermal losses incurred in the modern photovoltaic devices. Specifically, we are looking into ways to effectively utilize the incident sun light, prevent recombination pathways, and manage heat budget for a higher overall efficiency of the solar devices.
 
Wastewater Treatment
We are interested to degrade organic contaminants present in the wastewater effluents of various industries. We are particularly working on physical, chemical and biological routes or a hybrid process for capturing and detoxifying contaminants present in the wastewater. Our final goal is to develop an economical and efficient process for wastewater treatment at large scale.

Adhesion
We are interested in understanding and engineering the adhesion characteristics at the solid-solid and solid-fluid interfaces by modifying the physical and chemical properties of the interacting surfaces. The relevant applications may include, but not limited to, Easy-to-clean surfaces, Biofouling-resistant surfaces, Asphalt adhesion, etcetera. In particular, we are studying the roles of surface morphologies and surface chemistries in altering the interfacial forces (or surface free energy) to lead a desired adhesive response.
