Abstract: Flexible thermoelectric power generator was fabricated by vacuum evaporation method. The effect of evaporation current and substrate temperature on the performance of thermoelectric films was investigated. When the evaporation currents were 100 A for p-type film and 110A for n-type film, the films exhibit (0 0 1) oriented which enhanced thermoelectric properties. The optimized power factor of the p-type films was found to be about 0.97 × 10−4 W/m·K2 at the substrate temperature of 50 °C. The optimized power factor of the n-type films was found to be about 3.8 × 10−4 W/m·K2 at the substrate temperature of 100 °C. The output voltage of flexible device with 11 pairs of p-n legs was measured. And the output voltage was 50 μV/K calculated from the slope, when the temperature difference was 100 K, the output voltage was about 50 mV.
