Abstract: An ultraviolet photodetector with an active layer of solution processed polymer:quantum dot hybrid is introduced. Poly[9,9-di-(2-ethylhexyl)-fluorenyl- 2,7-diyl] represents the polymer and Zn0.71Cd0.29S is the quantum dot used for the device. Photophysical studies showed that an electron transfer from the polymer to the ternary quantum dot is thermodynamically favored. Quenching experiments performed between the polymer and quantum dot indicates the formation of a non-fluorescent complex with an association constant of 4.6 × 104 M-1. The device structure of ITO/PEDOT:PSS/ADS231BE: 50 wt% Zn0.71Cd0.29S/Al yielded a photoresponsivity value of 324 mA/W at -4 V under 1 mW/cm2 illumination at 365 nm at room temperature and this value is further increased to 380 mA/W as a result of annealing at 75 °C.
