all-polymer solar cells (all-PSCs) 1, nonfullerene acceptors (NFA) 2, perylene diimide (PDI) 3, energy levels 4, PCE 5For recent decades, non‐fullerene acceptors (NFAs) are undergoing rapid development and emerging as a hot area in the field of organic solar cells. Among the high ...
Naphthalenediimide-based n-type polymeric semiconductors are extensively used for constructing high-performance all-polymer solar cells (all-PSCs). For such all-polymer systems, charge recombination can be reduced by using thinner active layers, yet suffering insufficient near-infrared light harvesting fro...
