Thermoelectric materials offer a great advantage in generating electricity from ubiquitous heat yet facilitating noiseless, longstanding, and hassle-free operation. A considerable improvement in electrical conductivity has been reported through tuning the doping of Graphene Flake (GF) into p-type CoSb3 based skutterudite using Spark Plasma Sintering (SPS) method. In this paper, a full electrical property for the CoSb3-GFx based polycrystalline thermoelectric energy material has been reported. The electrical conductivity is found to be 33% more for the sample with 0.35 weight percentage (wt%) of graphene flake as compared to pristine CoSb3
