摘要：

The authors investigated the anode work function modified by series of self-assembled monolayers comprising alkanethiols and perfluorinated alkanethiols with different alkyl lengths on pentacene/fullerene thin-film organic solar cells. Via selecting different types of self-assembled molecules, the anode work function can be tailored for modifying the interfacial barrier. The measured open-circuit voltages indicated reduced anode work function that tends to form Schottky contact. The maximal open-circuit voltage and short-circuit current were measured to be 0.4 V and 17.7 mA/cm(2), respectively, in the case of anode work function modified by perfluorinated alkanethiols. The power conversion efficiency is 2.24%. (c) 2007 American Institute of Physics.
