摘要：

A nanostructured solid-state photodetector based on an inorganic/organic semiconductor heterojunction of TiO2 nanorod/spiro-MeOTAD is constructed. Spiro-MeOTAD serves as the active absorption layer and TiO2 offers a direct pathway for electron transport. A maximum photoresponsivity of 0.01 A/W was observed under illumination of 410 nm at 0V bias. The time response (decay time is 0.06 s and rise time is 0.12 s) was observed to be rapid. The self-powered device is a promising candidate for application in high-sensitivity and high-speed blue light photodetectors. These results provided a simple way to fabricate low-cost, high spectrum selectivity hybrid photodetector with large area. (C) 2013 AIP Publishing LLC.
