Longi ob-kawg tandem perovsskite solar hlwb muaj kev ua tau zoo ntawm 34.85%

Nyob rau hauv lub Plaub Hlis 2025, Longi tshaj tawm tias nws tus kheej tau tsim lub zog ua haujlwm tau muaj txiaj ntsig ntawm lub zog hauv lub ntiaj teb, NREL) Qhov kev sib tsoo no tsis yog tsuas yog cim ntawm photovoltaic siv tau cov kab mob crystall ntawm ultra-allis

Ntev cov txheej txheem yog ua raws li crystalline hlwb, thiab ua tiav lub meej spectral convenalarity los ntawm cov stacking tsim ntawm cov khaubncaws sab nraud. Tshwj xeeb, bandgap ntawm txog 1.7 ev) yog lub luag haujlwm rau nqus tau lub teeb pom kev zoo, thaum lub teeb ci (bandgap ntawm 1.1 ev) raug ntes teeb. Ob txoj haujlwm ua ke kom nce hnub ci zog hloov zuj zus mus 34.85%. Cov tub ntxhais ntawm cov qauv no nyob rau hauv qhov kev sib tawg ntawm interface engineering. Pab pawg ntev tau tsim tawm ob-txheej txheej txheem passivation lub tswv yim. Los ntawm cov nyhuv synergistic ntawm lithium fluoride (Lifessediamine DioiPide

Nws yog tsim nyog sau tseg tias ntev thev naus laus zis thev naus laus zis: kev ua haujlwm tau zoo tshaj plaws " Huneng Kev Tshawb Nrhiav Lub Zog Hluav Taws Xob, thiab Hong Kong Polytechnic University. Piv txwv li, kev tshawb fawb ntawm Xib faj Li YaWen pawg ntawm Sochow University muab kev txhawb nqa tseem ceeb rau kev txhim kho cov roj teeb ruaj khov; Huneng Huv Kev Tshawb Fawb Lub Zog Lub Chaw Haujlwm tau pab txhim tsa kev ua lag luam kev ua haujlwm hauv thaj chaw loj-ua haujlwm npaj thiab kev lag luam.

Kev tawg hauv kev ua qab nthab

Qhov kev txwv tsis pub tshaj ntawm cov crystalline silicon-perovskite tandem hlwb yog siab npaum li 43%, deb tshaj li ntawm 29.4% ntawm tib lub crystalline hlwb. Longi's 34.85% Kev ua tau zoo yog ze rau 80% ntawm qhov no theoretical tus nqi, tawm hauv chav txaus rau kev hloov pauv technology ntxiv. Yog hais tias lub triple-sib tshuam tandem (xws li pob zeb sib dhos / Crystall

Cuam tshuam kev ua kom zoo ntawm tus nqi qauv

Cov khoom siv silicon nqi ntawm cov tsoos crystalline li 40%, thaum txo cov khoom siv ntawm silicon tau tsawg dua 100 μm) thiab nce lub zog ib tiam ib cheeb tsam. Tsis tas li ntawd, cov txheej txheem kev daws teeb txheej ntawm cov txheej txheem xyoob ntoo (xws li cov txheej txheem slitSkite (siv cov inkjet nkaus xwb 1/10 ntawm lub zog ntawm cov nqi tshuab sirystalline, ntxiv txo cov nqi tsim khoom lag luam. Nws yog kwv yees tias tus nqi theem qis ntawm hluav taws xob (lcoe) ntawm cov kev sib tw teev hauv paus, thiab nws muaj cov kev sib tw tsoos tsho hauv cov photovoltAcs, BIPV thiab lwm yam xwm txheej.

Tso tawm ntawm Industrial Chargery nyhuv

Longi cov kev sib tw thev naus laus zis yuav ua kom loj hlob nrawm ntawm txoj kev lag luam saw? Piv txwv, TCO iav (pob tshab cov khoom siv oxide), raws li ib qho tseem ceeb rau cov pob txha tseem ceeb, tau nce nws tus lej hauv zos los ntawm 3025 202% hauv 2025; Lub tsev loj-thaj chaw tsim thev naus laus zis tsim los ntawm Huaneng Kev Tshawb Fawb Lub Zog tau nce cov txiaj ntsig ntawm cov kab ke ntawm 85% txog 95%. Ib qho ntxiv, Longi kev koom tes nrog GCL-poly Optoelectronics, XiannaSpetronics thiab lwm cov tuam txhab tau tsim ib qho "crystalline-crystalline silicon" kev sib koom tes kev lag luam ecology.

Txawm hais tias qhov sib txig ua tau zoo, ua lag luam tseem ntsib ntau yam kev cov nyom:

Ruaj Ntseg thiab Lub Neej Bumlenck

Cov ntaub ntawv thoob tsib tau nkag siab txog dej, oxygen, lub teeb thiab kub, thiab tsis muaj kev ruaj khov. Ntev cov hlwb tseem tsis tau tseem qhia tawm cov ntaub ntawv lub neej tshwj xeeb lub neej Txhawm rau kom daws tau cov teeb meem no, Longi yuav tau txais cov kev qhia txuj ci hauv qab no:

Interface passiveation: piv txwv li, tus tswv tsev tus qhua tau tsim los ntawm Zhang Hong's Team tuaj yeem ncua lub neej ntawm cov hlwb ntawm cov kab mob rau 1,050 teev.

Tshuab ntim tshuab: cov duab graphene-polymer txhim kho tshuab ntawm Huaneng Kev Tshawb Fawb Lub Zog Lub Tsev Haujlwm rau 3,670 teev.

Nyuaj ntawm Cov Txheej Txheem Ntau Lawm

Dand-terminal Tandem cells yuav tsum tau kho kom meej ntawm lub latsis sib txuam thiab interface kev sib tw ntawm cov txheej txheem pob zeb thiab cov crystalline txheej. Cov teeb meem hauv qab no yuav tsum tau daws thaum ntau ntau lawm:

Nyias zaj duab xis uniformity: cov tuab ntawm cov txheej txheem perovskite yuav tsum tau tswj hwm ntawm {}} nm, thiab cov tuab tuab yuav tsum tau tsawg dua 5%.

Process compatibility: There is a contradiction between the high-temperature process of crystalline silicon cells (>800 DEGREE) thiab qhov tsawg-qhov kub kev npaj ntawm perovskites (<150℃), and new materials such as low-temperature silver paste need to be developed.

Txoj cai thiab kev ua lag luam tsis meej

Txawm hais tias lub teb chaws "14th tsib-xyoo phiaj xwm" teev Perovskites, tam sim no tseem muaj cov txheej txheem kev lag luam kom meej thiab cov qauv kev lag luam ntshiab. Tsis tas li ntawd, cov txheej txheem rov ua dua rau cov khoom siv sib txawv tseem tsis tau tsim, thiab ua cov teeb meem muaj kuab paug yuav ua rau ib puag ncig kev sib cav.

Longi's 34.85% Kev ua kom muaj txiaj ntsig ua ke ntawm photovoltaic los ntawm "crystalline silicon dominance" rau "stacked era". Qhov kev sib tsoo no tsis yog tsuas yog thev naus laus zis yeej, tab sis kuj tseem muaj kev sib koom tes hauv kev tshawb fawb ua ke, thiab Hong Kong Polytechic lub peev xwm tsim ua ke ua ke ua ke tsim kho cov pob zeb ua ke.

Saib tom ntej, crystalline silicon-perovskite tandem hlwb yuav reshape toj roob hauv pes hauv cov chaw hauv qab no:

Faib photovoltaics:Nws lub teeb yuag (qhov hnyav module<5 kg/㎡) and high power density (>400 W / ㎡) Cov yam ntxwv yuav txhawb nqa qhov tshwm sim ntawm BIPV, tsheb-mounted photovoltaics thiab lwm yam xwm txheej.

Lub Zog Hluav Taws Xob:Kev txhim kho kev ua tau zoo tuaj yeem txo cov av hauv ib thaj chaw, uas yog qhov zoo dua nyob hauv cov cheeb tsam nrog cov chaw muaj tsawg.

Chaw tshawb nrhiav:Kev tshawb fawb thiab kev nthuav dav ntawm kev hloov pauv cov hlwb los yuav muab cov kev daws teeb meem ntau rau cov chaw sib sib zog.

Txawm li cas los xij, txoj kev mus rau kev ua lag luam tseem yuav tsum tau tawg los ntawm ntau cov nyom xws li kev ruaj khov, cov txheej txheem ntau zog thiab kev txhawb nqa txoj cai. Longi cov kev sib tw thev naus laus zis tau taw txoj kev lag luam, tab sis kom ua tiav "perovskite kiv kev", kev sib zog ntawm kev ua haujlwm ntawm tag nrho cov saw hlau tseem xav tau. Hauv tsib xyoos tom ntej no, kev lag luam photovoltaic yuav usher hauv kev hloov pauv ntawm kev siv hluav taws xob thiab ntev xyoo ntawm kev hloov pauv no.
