Paper Title:
Influence of Morphology of Vacuum-Evaporated Oligothiophene Derivative Films on Oganic Photovoltaic Performance
  Abstract

In order to understand the influence of morphology of vacuum-evaporated conjugated organic thin film on organic photovoltaic performance, oligothiophene derivatives, 2,3,4,5-tetrathienylthiophene (X-5T) and 2,5-dithienyl-3,4-di ((2,2') bithiophene-5yl) thiophene (X-7T), were prepared. The thermal behaviour and morphologies of vacuum-deposited X-5T and X-7T films were examined by differential scanning calorimetry (DSC) and x-ray diffraction (XRD). The influence of morphologies of vacuum-evaporated X-5T and X-7T films on organic photovoltaic performance was hen investigated. It was found that vacuum-evaporated oligothiophene derivative films possessing crystalline morphology could be beneficial to improve organic photovoltaic performance of device by promoting forward interfacial electron transfer and transport.
