Measurement of the Charge Carrier Mobility Distribution in Bulk Heterojunction Solar Cells

Abstract

Charge carrier transport through organic solar cells is fundamentally dispersive due to the disordered structure and complex film morphology within the photo active layer. A novel application of transient photocurrent and short-circuit variable time-delayed collection field measurements is used to reconstruct the complete charge carrier mobility distribution for the photogenerated carriers in optimized organic solar cells.
