有機無機金屬鹵化物鈣鈦礦太陽能電池（PSC）因其低成本和高功率轉(zhuǎn)換效率（PCE）而受到廣泛關(guān)注，型電顯示出潛在的商業(yè)價值。該工作為開發(fā)由多種化學(xué)鍵協(xié)同誘導(dǎo)的自下而上的整體載流子管理策略來提升器件的效率和穩(wěn)定性提供了借鑒，力系為鈣鈦礦太陽能電池的商業(yè)化應(yīng)用奠定了堅實的基礎(chǔ)。機制Fig.1.(a)Schematicillustrationofmultiple-chemical-bond-inducedbottom-upholisticmodificationbasedonTBHCl.(b)Sn3dand(c)O1sXPSspectraoftheSnO2filmswithoutorwithmodifiers.19FNMRspectraoftheSnO2solutionswithoutandwith(d)BTFand(e)TBHCl.1HNMRspectraoftheSnO2solutionswithoutandwith(f)BTFand(g)TBHCl.(h)FTIRspectraofSnO2,SnO2-TBHClfilm,andpureTBHClintherangeof1000-1200cm-1.(i)Pb4fXPSspectraoftheperovskitefilmspreparedonpristineSnO2andmodifiedSnO2withBTF,BHClandTBHCl.(j)19FNMRspectraofTBHCl,TBHCl+PbI2andTBHCl+FAI.(k)1HNMRspectraofTBHCl,TBHCl+PbI2,TBHCl+FAI,andFAI.Fig.2.(a)ElectrostaticpotentialmapofBTF,BHClandTBHClmolecules.(b)Bindingenergies(Eb)betweentheOVdefectsinSnO2,iodinevacancyandFAvacancydefectsinFAPbI3incontactwithBTF,BHClandTBHClmolecules.OptimizedstructuresofSnO2surfacecontainingOVdefects(c)withoutandwith(d)BTF,(e)BHCl,and(f)TBHCl.OptimizedstructuresofFAPbI3surfacecontainingiodinevacancydefects(g)withoutandwith(h)BTF,(i)BHCl,and(j)TBHCl.OptimizedstructuresofFAPbI3surfacecontainingFAvacancydefects(k)withoutandwith(l)BTF,(m)BHCl,and(n)TBHCl.Fig.3.DLSspectraoffreshandaged(a)SnO2,(b)SnO2-BTF,(c)SnO2-BHCland(d)SnO2-TBHCl.(e)Current-voltagecurvesforthedeviceswiththestructureofITO/SnO2withoutorwithmodifiers/Ag.TheITOandPCBMstandfortheindium-tinoxide-coatedglasssubstrateandphenyl-C61-butyricacidmethylesterlayer,respectively.(f)Electronmobilityoftheelectron-onlydeviceswiththestructureofITO/PCBM/SnO2withoutandwithBTF,BHClandTBHCl/PCBM/Ag.(g)XRDforthecontrol,BTF-,BHCl-andtheTBHCl-modifiedperovskitefilms.GIXRDpatternswithdifferentωvalues(0.5~1.5)for(h)control,(i)BTF-,(j)BHCl-,and(k)TBHCl-modifiedperovskitefilms.(l)Thed-spacingvalueofthe(211)planeasafunctionofgrazingincidenceangleforthecontrol,BTF-,BHCl-andtheTBHCl-modifiedperovskitefilms.Fig.4.Top-viewSEMimagesof(a)control,(b)BTF-,(c)BHCl-,and(d)TBHCl-modifiedperovskitefilms.Thescalebaris1μm.PLmappingimagesof(e)glass/perovskite,(f)glass/BTF/perovskite,(g)glass/BHCl/perovskiteand(h)glass/TBHCl/perovskitefilms.(i-l)Current-voltagecurvesfortheelectron-onlydeviceswhichwascomposedofITO/SnO2withoutorwithmodifiers/perovskite/PCBM/BCP/Ag.Fig.5.(a)TRPLspectraoftheperovskitefilmsbasedonthepristineSnO2andSnO2modifiedwithBTF,BHCl,andTBHCl.Transientreflectionkineticsfortheperovskitefilmsdepositedon(b)SnO2,(c)SnO2-BTF,(d)SnO2-BHCland(e)SnO2-TBHClETLs.(f)TPCand(g)TPVdecaycurvesofthePSCsbasedonSnO2,BTF-,BHCl-andTBHCl-modifiedETLs.(h)EISmeasurementofthedevicesbasedoncontrol,BTF,BHCl,andTBHClETLs.Theinsetshowsequivalentcircuitofthedevice.(i)Thelight-intensitydependenceofVOCcurvesforthecontrolandmodifieddevices.Fig.6.(a)JSC,(b)VOC,(c)FFand(d)PCEofthecontrolandPSCsbasedontheoptimalconcentrationofBTF,BHClandTBHCl.J-Vcharacteristicsofthebest-performingPSCsbasedon(e)control,(f)BTF,(g)BHCland(h)TBHCl.(i)J-VcurvesofthechampionTBHClmodifieddevicewithPEAIpost-treatment.(j)SteadystateoutputperformanceofthechampionPSCswithoutandwithBTF,BHClandTBHClmodification.(k)ThermalstabilityoftheunencapsulatedPSCswithoutandwithmodifiersat60℃inaN2-filledglovebox.(l)HumiditystabilitytestofunencapsulatedPSCswithoutandwithmodifiersagedunderarelativehumidityof15-25%atroomtemperatureinthedark.BaibaiLiu,1RuLi,1QixinZhuang,XuemengYu,ShaokuanGong,DongmeiHe,QianZhou,HuaYang,XihanChen,ShirongLu,Zong-XiangXu,*ZhigangZang*andJiangzhaoChen*.Bottom-upholisticcarriermanagementstrategyinducedsynergisticallybymultiplechemicalbondstominimizeenergylossesforefficientandstableperovskitesolarcells.JournalofEnergyChemistry2022,https://doi.org/10.1016/j.jechem.2022.09.037.。

鑒于此，全文重慶大學(xué)陳江照研究員、全文臧志剛教授及南方科技大學(xué)許宗祥副教授等人提出了一種由多種化學(xué)鍵協(xié)同誘導(dǎo)的自下而上的整體載流子管理策略，以最大限度地減少高效鈣鈦礦太陽能器電池的體相和界面能量損失。通過TBHCl改性，｜適抑制了SnO2納米粒子的團聚、｜適鈍化了ETL中的氧空位缺陷和鈣鈦礦薄膜中的缺陷以及釋放了鈣鈦礦膜中的拉伸應(yīng)變，從而將PCE從21.28%提高到23.40%。
