Electrical performance of MEH-PPV/ZnO nanocomposite at various weight percentage concentration prepared by spin coating method for OLED

Abstract

An organic semiconductor have been discovered and commercialized for many application particularly in organic light-emitting diodes (OLEDs). In OLEDs application, the organic materials play the role of emitting light once the current is passed through. The electrical properties and surface morphology study are investigated for poly [2-methoxy-5(2'-ethylhexyloxy)-phenylene vinylene) (MEH-PPV) with zinc oxide (ZnO) nanocomposite films prepared using spin coating technique. The MEH-PPV/ZnO nanocomposite films were deposited on ITO coated glass substrates at various weight percentage concentrations. The surface morphology (FESEM) investigation showed that the nanotetrapods size of ZnO increased with higher concentration up to 0.4 wt%. While, the electrical properties of nanocomposite films were measured using 2-point probe solar simulator to obtain the current-voltage for OLED device.
