Traditional binary solvent engineering has limitations for FAPbI₃ films because of rapid solvent evaporation at high annealing temperatures. Accordingly, this research proposes ternary solvent engineering (TSE) using dimethylformamide (DMF), dimethyl sulfoxide (DMSO), and anisole (AN), which delays crystallization by forming hydrogen bonding. This finding demonstrates that AN, which is typically used as an antisolvent, can be effectively utilized as a PbI₂ precursor solvent. This approach affords larger grain sizes, reduces surface roughness, and improves charge transport, leading to an improvement in PCE from 12.23 % to 13.85 % by enhancing the fill factor. The results of this study suggest that TSE with AN can significantly enhance the performance of PSCs, providing a new pathway for efficient perovskite film fabrication.</div></div>","PeriodicalId":399,"journal":{"name":"Organic Electronics","volume":"138 ","pages":"Article 107193"},"PeriodicalIF":2.7,"publicationDate":"2024-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143156570","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The dendronised co-ligand, 5-phenyl-1-methyl-3-<em>n</em>-propyl-1<em>H</em>-1,2,4-triazole, was found not to contribute to the colour of the emission. The first- and second-generation dendrimers that had two emissive 2-phenylpyridyl ligands were found to have high solution photoluminescence quantum yields (PLQYs) of nearly 90 % whereas the homoleptic dendrimers and the one with a single emissive ligand had PLQYs of around 70 %. The PLQY values decreased in the solid-state, with the second-generation dendrimer with a single emissive ligand found to have the highest neat film PLQY of 55 %. This was attributed to the dendronised co-ligand acting as a self-host to reduce the intermolecular interactions that lead to the quenching of the luminescence. Organic light-emitting diodes (OLEDs) composed of neat films of the dendrimers had relatively poor performance, with unbalanced charge transport and a maximum external quantum efficiency (EQE) of 6.5 % for the second-generation dendrimer with a single emissive ligand.

Here, the influences of high dielectric capacitance on the performance of low voltage n-channel organic field-effect transistors based on poly([N,N′-bis(2-octyldodecyl)-naphthalene-1,4,5,8-bis(dicarboximide)-2,6-diyl]-alt-5,5′-(2,2′-bithiophene)) (P(NDI2OD-T2) OFETs) were examined.

In this study, we address this challenge by introducing self-assembled monolayers (SAMs) between the electron transport layer (ETL) and QDs. By employing two distinct SAMs with opposite dipole moments—4-methoxybenzoic acid (MBA) and 4-cyanobenzoic acid (CBA)—we provide direct evidence that electrons are in excess in InP QLEDs. The contrasting charge injection modulation effects of these SAMs enabled this clear identification of the excess carriers. Additionally, the SAMs improved surface morphologies and effectively passivated surface defects on the ZnO ETL, mitigating exciton quenching. As a result, MBA-treated QLEDs demonstrated superior device efficiencies compared to pristine or CBA-treated devices, attributed to the suppression of electron injection from the ETL to the QDs.
