Interfacial layers (ILs) are prerequisites to form the selective charge transport for high-performance organic photovoltaics (OPVs) but mostly result in considerable parasitic absorption loss. Trimming ILs down a mono-molecular level via self-assembled monolayer is an effective strategy mitigate However, such suffers from inferior electrical contact with low surface coverage on rough surfaces and poor producibility. To address these issues, here, interlayer (SAI) developed, which involves thin layer of 2-6 nm full substrate both covalent van der Waals bonds by using molecule 2-(9H-carbazol-9-yl) (2PACz). Via facile spin coating without further rinsing annealing process, it not only optimizes optical properties OPVs, enables world-record efficiency 20.17% (19.79% certified) also simplifies tedious processing procedure. Moreover, SAI especially useful improving absorbing selectivity semi-transparent record light utilization 5.34%. This work provides optimize OPVs solar window applications.
