In the fields of alternative energy and environmental research, practical applications and devices are important in developing and furthering the field. In the Kamat Lab we seek to apply our understanding and research of the fundamental science behind these processes to the development of improved devices and real world applications.

Solar Cells

In the coming years there will almost certainly be an increased need for cost-effective, efficient, photovoltaics. By harnessing the unique properties of semiconductor nanoparticles or quantum dots, we seek to increase the efficiency and further the understanding of Quantum Dot-Sensitized Solar Cells.

Hydrogen Generation

For photovoltaics, one of the major hurdles to widespread adaptation is the intermittency of sunlight. Solar hydrogen generation from water offers a unique method of direct fuel production from sunlight and water. By studying the evolution of hydrogen, we seek to gain a better understaning of the photocatalytic generation to design better catalysts for this process.

Batteries

Many of the most promising renewable energy sources available suffer from energy storage issues. To better utilize these green energy sources, improved batteries must be developed. Using our understanding of electron transfer processes, we aim to develop lithium ion batteries with improved capacities and better lifetimes.

Chemical Sensors

One important need for environmental cleanup is the detection of toxic pollutants at very low concentrations. Using the unique properties of graphene, its high surface area and conductivity, semiconductor-graphene-metal (SGM) composites can be used to enhance the raman signal seen from different pollutants, lowering detection limits.
