Effect Of Electrode Material On The Voltage Generation Of Pzt Nanowire Based Nanogenerator

In this work, the effect of electrode materials on the voltage generation as well as the internal resistance of the nanogenerators have been studied. Piezo-electric polycrystalline tetragonal nanowires of Pb(Zr0.52Ti0.48)O-3 (PZT) grown by hydrothermal technique were used as the generating material. As an electrode material noble metal gold (Au) as well as copper (Cu) were used. It has been found that the voltage generated by using copper electrode is maximum around similar to 1 V. It has also been observed that output power of the nanogenerator enhances from 80 nW to 350 nW with a concomitant reduction of internal resistance. An effective dependence on work function of the electrode material has been established.
