Paper Title:
TiOx Concentration Dependence of OPV Efficiency Optimization
  Abstract

Titanium oxide TiOx material is used as electron transporter in organic photovoltaic cells (OPV). The layer was prepared between P3HT:PCBM as the active layer and the and aluminum electrode by spin coating technique. The synthesis and characterization of TiOx is described. Using Raman spectroscopy technique TiOx crystals show anatase structure. Varied concentrations of TiOx and isopropanol solvent were performed. The most optimized device efficiencies up to 2,0% was achieved at a 1:20 ratio, which indicated more than 50% efficiency enhancement comparing with the device without TiOx layer. The major improvement of the cell was originated from photocurrent enhancement.
