Abstract

Cu2SnS3 (CTS) nanostructures were synthesized using the solvothermal method and used in a CTS-polymer inorganic-organic hybrid device to study the enhancement in the infrared (IR) photo-response. The structural and optical properties of the CTS nanostructures were measured. The IR photoresponse was measured for both the P3HT-PCBM polymer blend and various concentrations of CTS in P3HT-PCBM. The responsivity, sensitivity, external quantum efficiency and specific detectivity were found to be 19.4 mA W-1, 1.4, 3.01% and 7.97 x 10(8) Jones respectively for the P3HT: PCBM = 1: 1 sample and 211.5 mA W-1, 3.6, 32.8% and 8.7 x 10(9) Jones respectively for CTS: P3HT: PCBM = 12: 1: 1 sample at 1 Vbias and 477.7mWcm(-2) IR illumination intensity. The photoresponse was also measured under 1550 nmlaser illumination of 1100 mW cm(-2) intensity. The time dependent photoresponse showed good cyclic stability over time for different ON-OFF cycles. CTS nanostructures prove to be beneficial in enhancing the photoresponse of the IR photodetector device.
