Overview
Thermoelectric materials can directly convert heat into electric energy. This can be especially useful for harnessing low-temperature waste heat from inefficient energy conversion processes or to power small personal devices simply based on the heat radiating from our bodies. However, state-of-the-art thermoelectrics demonstrate low efficiency and incorporate materials containing rare and toxic elements.
Our group has been focusing on more environmentally benign alternatives such as Cu2Se and Ag2Se, both as colloidal quantum dots and direct thin films, and we are exploring different avenues for increasing the performance and operational stability of these materials on rigid and flexible substrates.
Our current experimental setup has the ability to measure Seebeck coefficients and electrical conductivity in an inert atmosphere in the temperature range 10 - 70 degrees Celsius for extended periods of time.
