Effects of molybdenum trioxide thickness of organic photovoltaic with silver anode

Abstract

We demonstrated the layer thickness effects of molybdenum-trioxide (MoO3) as buffer layer inserting at the interface between silver anode and organic material of a top-incident organic photovoltaic (OPV). The OPV structure contained active bilayer layers using 1,1-bis[(di-4-tolylamino)phenyl]cyclohexane (TAPC) and fullerene (C70). In this study, we obtained an OPV with 5-nm MoO3 showing the greater power conversion efficiency of 2.78%. In addition, this optimized OPV result was caused from the greater short circuit current (Jsc of 11.35 mA/cm2) and fill factor (FF of 47.12).
