Abstract
This thesis aims to a solution processable infrared Photodetector on single-walled carbon nanotube (SWNTs) electrodes. Compare to the conventional indium tin oxide conductive electrodes had disadvantages of expensive high vacuum deposition process, rigid and non-flexible properties, we can deliver a simple and low-cost solution process on fabricating SWNTs thin film electrodes which could transfer to various substrates. Conductive and transparent SWNTs thin film had the advantages of large area processable, flexible and good infrared transmittance. We apply two different device structures on SWNTs electrode: Schottky junction diode and Bulk HeteroJunction diode.Finally we get a great infrared photo response for a P3HT/PCBM/PbS hybrid BHJ infrared Photodetector on SWNTs electrode with 0.4% external quantum efficiency at 1460nm.Therefore we can fabricate a all-solution processable, low cost infrared Photodetector on SWNTs electrodes.
