Summary: In this study, a novel alcohol-soluble nitrogen oxide radical conjugated polymer (PBN-NO) with dimethylamine groups and TEMPO radical side-chain groups was developed as a cathode interfacial modifer (CIM) in organic solar cells (OSCs). Compared to commonly used CIMs, such as PFN, PDINO, and PDINN, the OSCs with PBN-NO exhibited higher or comparable power conversion efficiencies (PCEs) (16.19% vs 13.10%, 15.60%, and 16.15%), as well as improved photostability and thermal stability. The reasons for the improved PCEs were systematically investigated through various comparative experiments, including exciton dissociation, charge recombination, capacitance-voltage (C-V) measurements, etc. This is the first report on an alcohol-soluble nitroxide radical conjugated polymer that combines the interfacial modification of polar groups and enhanced conductivity through dangling radicals, contributing to efficient OSCs with enhanced stability.

Summary: The performance of organic solar cells is determined by the morphology of the active layer. Traditional solution-based methods have poor performance due to the random distribution of materials. Moreover, the solvents and additives used in traditional fabrication processes have negative effects on human health and the environment. In this study, a strategy using all-green solvent and additive combination with sequential deposition (SD) technique was proposed to control the morphology of the active layer. The results showed higher power conversion efficiency of devices fabricated using this strategy compared to control devices.

Summary: Perovskite light-emitting diodes (PeLEDs) show promise for next-generation high-definition displays due to their excellent color purity and low power consumption. A novel strategy of interfacial molecule control is demonstrated using a bifunctional material to enhance interaction and exciton management between the perovskite and electron-transport layers. This modification layer not only passivates surface defects but also blocks interfacial exciton transfer, resulting in improved external quantum efficiencies for green, blue, and red emissions.

Summary: Interface engineering is crucial for improving the performance of perovskite devices. In this study, two perylenediimide small molecular cathode interface materials (CIMs), PDI-2N and PDI-4N, were synthesized and used as cathode interfacial layers (CILs) for inverted perovskite solar cells (PVSCs). PDI-4N showed higher electrical conductivity, electron mobility, and self-doping properties compared to PDI-2N. Utilizing PDI-4N as CIL achieved the highest peak power conversion efficiency (PCE) of 21.33% among PDI-based interlayer materials in inverted PVSCs. The improved device efficiency with PDI-4N was attributed to reduced defect density, lower dark current, larger recombination resistance, and better surface morphology, enhancing charge transport and collection at the PC61BM/Ag interface. Moreover, PVSCs with PDI-2N and PDI-4N as CILs exhibited good stability with only a approximately 3.0% PCE loss after 600 hours.
