Nanogenerators and the Future of Energy

Thursday, November 15, 2018

There are many researchers searching for new and clean sources of energy. However, few are conducting research at the intersection of nanotechnology and quantum phenomenon. Professor Dayan Ban, from the Department of Electrical and Computer Engineering, is conducting seminal research in the area of quantum photonics and nanoelectronics.

His main objective is to develop advanced semiconductor quantum photonic and nanoelectronic devices for Professor Dayan Ban terahertz communication, terahertz imaging, sensing and energy harvesting. Professor Ban designed and created prototypes of high-performance quantum devices. Thesedevices convert infra-red light directly to visible light (green) at room temperature. These experiments led Professor Ban to fabricate a hybrid energy harvester based on a nanogenerator and solar cell.

The United States Energy Information Administration projects a 28 percent increase in world energy use by 2040. To reduce the burden on the world’s limited energy resources novel technologies must be developed to harvest energy from non-traditional sources.

Professor Ban and his collaborators are focused on harvesting energy from ambient sources, such as vibration, thermal, acoustic or solar. This energy can also be harvested from remote sources, such as radio-frequency or acoustic beacons. An example is the powering of sensors on an airplane wing through the mechanical vibration of the plane itself. Thermoelectric generators can be attached to a heat-generating source such as an engine.

“Our goal is to use nanotechnology to develop nanogenerators and light emitting diode to be commercialized for general applications,” said Ban.

“This research is only possible at the Waterloo Institute for Nanotechnology. The diverse group of researchers provides all of us with an opportunity to collaborate and proposed unique solutions to society’s challenges.”

We do not currently know the full extent of the application for these nanogenerators. However, the ability to harvest energy from mechanical, thermoelectric or light sources will drastically reduce the carbon emissions associated with traditional forms of energy production.

Professor Dayan Ban is a member of the Next Generation Energy Systems thematic group.
