This study presents a cost-efficient strategy for precise control over the dimensions, shape, size, and phase, of nanocrystals by modulating Pb(II) counteranions during hot-injection synthesis. By employing diethyl 2-bromomalonate as the bromide precursor, distinct nanocrystal morphologies were achieved using different lead sources: lead acetate, lead bromide, lead oxide, and lead nitrate yielded 1D nanorods, 2D nanoplatelets, 3D nanocubes, and quantum dots (QDs), respectively. The resulting CsPbBr3 nanocrystals exhibited high photoluminescence quantum yields (PLQY > 90%) and prolonged excited-state lifetimes (τ ≈ 6.1–15.1 ns). Furthermore, these nanocrystals displayed variable photocatalytic efficiencies in radical cascade cyclization reactions involving N-alkyl/aryl-maleimide and N-phenyl glycine under visible light (blue LED) in dichloroethane. Notably, the reaction yields were strongly influenced by the distinct sizes and morphologies of the nanocrystals.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"1 1","pages":""},"PeriodicalIF":22.0,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143546824","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using density functional theory and nonadiabatic molecular dynamics simulations, we reveal a self-passivation mechanism at the SnO2/CH3NH3PbI3 interface to enhance the stability and efficiency of the device, which is mainly attributed to a benign iodine vacancy (VIact). Unlike the typical defects of accelerating the charge recombination and reducing efficiency, this distinctive VIact facilitates charge transfer and decelerates nonradiative recombination by passivating the potential trap states. Additionally, the benign VIact at the interface reduces structural distortion and suppresses electron–vibration interactions, which in turn, extends the charge carrier lifetime and enhances the electron injection. Furthermore, VIact exhibits both thermodynamic and kinetics stability. Our findings rationalize the high performance of SnO2-based perovskite solar cells and highlight the importance of the defect self-passivation strategy in optimizing interfacial properties for enhanced solar cell efficiency.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"66 1","pages":""},"PeriodicalIF":22.0,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143526451","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
