Abstract

Solvent-dependent self-assemblies of perylene bisimide (PBI) are applied as cathode modification layers in inverted polymer solar cells (i-PSCs) to afford a power conversion efficiency (PCE) as high as 9.11%. The very high device performance clearly indicates that n-type perylene bisimide based supramolecular assemblies are most promising interfacial materials for highly efficient i-PSCs.
