RESEARCH ACTIVITIES AND COLLABORATIONS:
Hydrogen storage in nanostructures
To sustain the growing global energy demand and at the same time minimize carbon emissions, there is a need to develop clean and renewable energy alternatives. Hydrogen fuel cell technology is among the various areas of interest which could potentially support the development of alternative ways to meet energy needs. On-board hydrogen storage remains to be a challenging aspect of this technology. We are carrying out computer simulations to study molecular hydrogen storage capacity of nanostructured cabon materials such as graphene (with Oak Ridge National Laboratory) and nanofoams (with Rice University). We are also working with the Computational Materials Research Cluster at WSU http://www.engineering.wright.edu/nanocenter/cmrc.shtml) on a project to investigate hydrogen adsorption on silicene.
Organic photovoltaic materials
Organic photovoltaic (PV) materials are considered to be one of the promising low cost alternatives to silicon solar cells, and they offer advantages, including relatively easier processing and large-area scalability. However, the power conversion efficiency achievable is way below the efficiency of commercial Si solar cells. In this work, we are studying the factors that affect their performance efficiency. Our experiments, in collaboration with Fisk University, involve measurements to understand the barrier to efficient extraction of electrons during the operation of a solar cell under artificial sunlight. We would like to understand the correlation between this barrier and the power conversion efficiency.
