High-efficiency thermoelectric (TE) materials are an important materials system for power generation that can directly convert thermal waste heat into electrical energy which plays a key role in our current challenge to develop alternative energy technologies to reduce our dependence on fossil fuels and to reduce greenhouse gas emissions. The power conversion efficiency of TE materials for TE generators is proportional to the so-called figure of merit ZT. Organic materials, such as polymers, are attractive thermoelectrics due to their low thermal conductivity, but face similar challenges in optimization as their inorganic counterparts. Inorganic hybrid composites, present a unique opportunity to optimize ZT via molecular and interfacial design in ways not possible in more classical systems. We investigate novel organic-inorganic hybrid materials for thermoelectric applications. The goal is to realize efficient low temperature (T < 100°C) thermoelectric hybrid thin films. We attempt to improve the figure of merit ZT, by combining nanostructured inorganic materials with the electrically conducting polymer blend PEDOT:PSS.
