dc.description.abstractSolution processed ultraviolet photodetectors with conventional and inverted architectures with active layers composed of poly(9,9-dioctylfluorenyl-2,7-yleneethynylene) (PFE) and zincoxide (ZnO) nanoparticle hybrid are introduced. Under 1 mW/cm(2) illumination intensity at 365 nm wavelength and for -4 V bias and room temperature, the conventional device structure of ITO/PEDOT: PSS/PFE: ZnO/Al and the inverted device structure of ITO/PFE: ZnO/Au are yielded photoresponsivity values of 311 and 244 mA/W, detectivity values of 1.4 x 10(14) and 5.1 x 10(13) cmHz(1/2)W(-1), and external quantum efficiency values of 105.6% and 82.7%, respectively. By annealing the active layer at polymer's glass transition temperature (T-g; 60 degrees C) for 15 min, these values are increased to 375 and 280 mA/W, 1.6 x 10(14) and 5.3 x 10(13) cmHz(1/2)W(-1), 127% and 95%, as in the above order. Performance, stability, and detectivity value differences between conventional and inverted architectures are explained electrically by impedance spectroscopy.en_US
