A perylene diimide-based non-fullerene acceptor as an electron transporting material for inverted perovskite solar cells†
Abstract
Herein we introduce a new perylene diimide dimer (diPDI) as a non-fullerene electron transporting layer (ETL) material for inverted perovskite solar cells. The solar cell device with n-doped diPDI as ETL exhibits a notable power conversion efficiency of 10.0%.
