Abstract

The series resistance of organic photovoltaic (OPV) devices was decreased by reducing the sheet resistance (Rsh) of the indium tin oxide (ITO) electrode, which leads to increasing device efficiency. The performance of bulk heterojunction OPVs was critically dependent on Rsh of the ITO electrode. Upon reducing Rsh of the ITO from 39 to 8.5 , the fill factor and power conversion efficiency of OPV was improved (from 0.407 to 0.580 and from 1.63±0.2 to 2.5±0.1%, respectively) under an AM1.5 simulated solar intensity of 100 mW cm2. The dependence of the series resistance on Rsh of the ITO suggests the dominance of the bulk resistance of the ITO electrode as a limiting factor in practical cell efficiencies.
