Solid State Photovoltaic Cells Using Poly-[2-Methoxy-5-(2-Ethylhexyloxy)-Phenylene Vinylene as Hole Transport Material


Article Preview

Solid state photovoltaic cells have been fabricated using a ruthenium dye complex as a sensitizer, and poly[2-methoxy-5-(2-ethyl-hexyloxy)-phenylene vinylene] (MEH-PPV) as a hole transporting layer. A compact TiO2 layers with no pores has been introduced to prevent charge losses related to back reactions. The photovoltaic properties of MEH-PPV/dye coated TiO2 electrodes and MEH-PPV coated TiO2 electrodes with and without using compact TiO2 layers were investigated. The compact TiO2 layer increased the current from 0.09 mA/cm2 to 0.4 mA/cm2. Further improvement in current was achieved by inserting a dye interlayer between nanoporous TiO2 and MEH-PPV. In this case, the current increased up to 2 mA/cm2 yielding an efficiency of 0.3 %.
