In this work, we demonstrate a facile way to fabricate hybrid heterojunction photodetector with poly (3-hexylthiophene) (P3HT) and a 1D ZnO nanorod (NR) arrays as the electron donor and acceptor, respectively. The ZnO NRs were synthesized by a low temperature two-step hydrothermal method on n-type silicon substrate. Graphite and eGaIn were used as ohmic contacts to P3HT film and Si substrate, respectively. Basic electrical parameters for eGaIn/Si/ZnO/P3HT/Graphite structure were calculated from I-V characteristics under dark and various power illuminations. The device exhibits high sensitivity to UV light illumination with a large degree of reproducibility. A short-circuit current Isc of 19.4μA, an open-circuit voltage Voc of 0.24V giving rise to a responsivity of about 21.7 mA/W have been obtained for the illuminated graphite/ P3HT/ZnO NRs/Si/EGa-In structure based near UV light sensor The origin of photoconductivity properties of ZnO/P3HT device has been explained using carrier transport mechanism at interfaces.
