TE Measurements on Prototype Seebeck Coefficient: S=−∆V/∆T Measure using voltmeter and thermocouple while heating Measured a value of 6.36 μV/K Attempted to measure electrical conductivity using four point probe: R= l/σA Unable to obtain measurements using 4 pt. probe
31 Conclusions: Thermoelectric Goals and Insight from Results Goal: to fabricate nanofiber TE device that rivaled that of PEDOT:PSS thin films in terms of Power Factor and efficiency Insight from Results: If percolation is reached, can obtain similar efficiency to a doped PEDOT:PSS thin film (Less conductive polymer required)
