Optimisation of properties of electrodeposited thermoelectric films of Bi0.5Sb1.5Te3
Significance of output:
This paper combines theory, experimental validation and material processing to design systems with optimised Seebeck coefficients for use in of a thermoelectric energy harvesting devices. This fundamental work enabled the subsequent fabrication of devices (using a sodium ligninsulfonate surfactant) with higher Seebeck coefficients (up to 50%) than those without the surfactant produced by other researchers. This increase in performance has the potential to be used in thermoelectric energy harvesting systems where low (<10C) thermal gradients exist and, as a result, the work led to patent GB 0722968. The concepts have subsequently been adopted by researchers in Korea and Germany.
