Abstract: |
Organic device with structure of ITO (20 Ω)/ PEDOT: PSS (60 nm)/ NPB (40 nm)/ Cu-complex (25 nm)/ LiF (1 nm)/ Al (100 nm), was fabricated, which show white electroluminescence (EL) or photovoltaic (PV) properties when it was driven by direct current (DC) bias or illuminated by ultraviolet (UV) light. Under a DC bias, the device shows white EL emission. which corresponds the Commission International de L’Eclairage coordinates (CIE) changes from (0.332,0.306) to (0.328,0.300) When the bias was increased from 7 v to 12 V. When the device was irradiated by a 365 nm UV-light 1.7 mW/cm2), the open-circuit voltage (Voc) of 1.94 V, shortcircuit (Isc) of 49.7μA/cm2, fill factor (FF) of 0.21 and power conversion efficiency of 1.19% have been determined, respectively.
