High-Performance Inverted Organic Photovoltaics with Over 1-μm Thick Active Layers
An efficiency of 8.62% is observed from inverted organic photovoltaics (OPVs) composed of a bulk heterojunction (BHJ) active layer with a thickness of 280 nm. Remarkably, an efficiency of 7.24% can be obtained using OPVs with a BHJ thickness of 1000 nm. Such high efficiencies from thick BHJ composite films are attributed to the high hole mobility and ordered molecular structure of the electron-donor polymer.
