- The properties of vanadium-doped indium oxide (IVO) deposited at room temperature as a transparent conductor for inverted polymer solar cells have been investigated as a function of the vanadium doping concentration. IVO film prepared with V doping concentration of 0.03% showed optimal properties for use as a transparent conductor with figure of merit of 4.35 x 10(-3) Ohm(-1), related to altered band alignment between the Fermi level and conduction-band minimum. In the optimal optoelectrical conditions for the IVO film, performance optimization of PTB7:PC70BM inverted polymer solar cells resulted in maximum power conversion efficiency of 4.7 +/- 0.4% under simulated air mass 1.5 global illumination at 100 mW/cm(2).
