Combination of Titanium Oxide and a Conjugated Polyelectrolyte for High‐Performance Inverted‐Type Organic Optoelectronic Devices

Abstract

Interface engineering by combination of TiOx and a conjugated polyelectrolyte as an electron transport layer modifies the electrical contact between a metal electrode and an organic active layer with well-aligned frontier orbital energy levels for efficient charge transport. This results in remarkable improvements in the device performance of inverted polymer solar cells and polymer light-emitting diodes.
