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 sub
