Fullerene‐Liquid‐Crystal‐Induced Micrometer‐Scale Charge‐Carrier Diffusion in Organic Bulk Heterojunction

The short charge‐carrier diffusion length (LD) (100–300 nm) in organic bulk heterojunction (BHJ) impedes the further improvement in power conversion efficiency (PCE) of organic solar cells (OSCs), especially for thick‐film (>400 nm) devices matching with industrial solution processing. Here a fac...
