title: High response organic deep ultraviolet photodetector with PEDOT:PSS anode.
abstract: We have fabricated an organic deep ultraviolet photodetector (PD) using PEDOT:PSS (PH 1000) as a transparent anode. NPB and PBD were employed as electron donor and acceptor, respectively. The PD exhibits a dark current of 0.0829 μA/cm(2) and a photocurrent of 85.3 μA/cm(2) at -12 V under 280 nm light illumination with an intensity of 0.488 mW/cm(2). A high response at 248-370 nm with its peak of 0.18 A/W at 280 nm and a detectivity of 1.1×10(12) cm Hz(1/2)  W(-1) were achieved. The more detailed mechanism of harvesting high performance and the dependence of photocurrent density on illumination intensity are also discussed.
