Low-Temperature Solution-Processed Molybdenum Oxide Nanoparticle Hole Transport Layers for Organic Photovoltaic Devices

High performance hole transport layers are realized using room temperature solution processing of microwave‐synthesized MoOx nanoparticles. Composition of solution‐deposited MoOx nanoparticle films can be increased from 10% to 70% MoO3 using air exposure (days) and reaction with H2O2 (minutes). The...

Zusammenfassung:High performance hole transport layers are realized using room temperature solution processing of microwave‐synthesized MoOx nanoparticles. Composition of solution‐deposited MoOx nanoparticle films can be increased from 10% to 70% MoO3 using air exposure (days) and reaction with H2O2 (minutes). The increased MoO3 content correlates well with improved solar cell performanceto the level of evaporated MoO3 and PEDOT:PSS, with good air stability.
