新时代电力脱贫更精更准新一轮农网改造计划即将来临

随着消费者环保意识的增强，代电涂料的功能性也开始多样化。

F可以通过与FA+形成氢键来抑制阳离子迁移和调节结晶，力脱临并且可以通过与Pb2+配位来钝化铅缺陷。钙钛矿和SnO2薄膜的埋底界面有许多缺陷，贫更这些缺陷会阻碍载流子的提取，导致界面电荷积累和界面非辐射复合。

有机无机金属卤化物钙钛矿太阳能电池（PSC）因其低成本和高功率转换效率（PCE）而受到广泛关注，精更计划即显示出潜在的商业价值。该工作为开发由多种化学键协同诱导的自下而上的整体载流子管理策略来提升器件的效率和稳定性提供了借鉴，准新为钙钛矿太阳能电池的商业化应用奠定了坚实的基础。农网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.。

鉴于此，改造重庆大学陈江照研究员、改造臧志刚教授及南方科技大学许宗祥副教授等人提出了一种由多种化学键协同诱导的自下而上的整体载流子管理策略，以最大限度地减少高效钙钛矿太阳能器电池的体相和界面能量损失。通过TBHCl改性，代电抑制了SnO2纳米粒子的团聚、代电钝化了ETL中的氧空位缺陷和钙钛矿薄膜中的缺陷以及释放了钙钛矿膜中的拉伸应变，从而将PCE从21.28%提高到23.40%。
