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

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 remarkab...

Description
Summary: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.
