Thermoelectrics have been considered a new renewable source of energy due to the waste heat harvesting capabilities. Current organic thermoelectric materials have yet to achieve the target figure of merit for commercialization. Poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate)(PEDOT:PSS) has become one of the most promising candidate materials for thermoelectric applications due to its relatively low thermal conductivity, and high conductivity. In order to further increase the thermoelectric figure of merit of PEDOT:PSS, the seebeck coefficient must be further improved. Into the PEDOT :PSS matrix, we incorporate lead halide perovskite crystals, which has recently been recognized as a potential thermoelectric material because of its high seebeck coefficient and low thermal conductivity. Furthermore, we evaluate the seebeck coefficient and electrical conductivity of pristine PEDOT:PSS and lead halide perovskite/PEDOT:PSS composites. |
