Dab tsi yog daim ntawv thov kev cia siab ntawm photovoltaic vuam sawb dov zeb

       Raws li cov khoom siv tseem ceeb rau photovoltaic vuam sawb ntau lawm, daim ntawv thov kev cia siab ntawm photovoltaic vuam sawb dov zeb ze ze rau kev loj hlob tawg ntawm kev lag luam photovoltaic. Nyob rau tib lub sijhawm, nws tau txais txiaj ntsig los ntawm kev kho dua tshiab ntawm vuam sawb thev naus laus zis thiab cov qauv ntawm kev hloov khoom siv hauv tsev. Zuag qhia tag nrho, nws nthuav tawm cov qauv zoo ntawm kev thov muaj zog, thev naus laus zis tau hloov kho dua tshiab, thiab txuas ntxiv nthuav dav ntawm qhov chaw lag luam. Kev tsom xam tshwj xeeb tuaj yeem ua los ntawm cov hauv qab no:

       Kev nthuav dav ntawm kev lag luam photovoltaic coj cov kev xav tau ruaj khov: Photovoltaic ribbon yog lub npe hu ua "cov hlab ntsha" ntawm photovoltaic modules thiab yog cov khoom siv tseem ceeb rau kev sib txuas hnub ci. Cov dov thiab lwm yam txheej txheem ntawm photovoltaic ribbon dov zeb ncaj qha txiav txim siab qhov tseeb thiab zoo ntawm cov ribbon, uas nyob rau hauv lem cuam tshuam lub zog tsim efficiency ntawm photovoltaic modules. Tsav los ntawm lub ntiaj teb ob lub hom phiaj carbon, kev lag luam photovoltaic loj hlob sai. Nyob rau hauv thawj ib nrab ntawm 2025, Tuam Tshoj tus tshiab tsim photovoltaic muaj peev xwm mus txog 212.21GW, ib xyoo-rau-xyoo nce ntawm 107.07%; Kev thov thoob ntiaj teb rau photovoltaic ribbon yuav ntau tshaj 1.2 lab tons hauv 2023 thiab xav tias yuav ncav cuag 2 lab tons los ntawm 2025. Kev nthuav dav ntawm cov khoom siv hluav taws xob qis qis yuav ua rau muaj kev xav tau loj heev rau photovoltaic vuam strips, yog li qhib qhov chaw ruaj khov thiab loj loj rau kev lag luam photovoltaic vuam strip rolling. Thiab nyob rau hauv lub neej yav tom ntej, mainstream tshiab Cheebtsam xws li heterojunctions thiab TOPCon tseem yuav siv photovoltaic ribbon raws li lub ntsiab kev twb kev txuas txoj kev, ntxiv kom ntseeg tau lub sij hawm ntev kev thov ntawm dov mills.

       Kev hloov kho ntawm vuam sawb thev naus laus zis tau yuam cov cuab yeej siv iteration thiab tsim cov kev nce ntxiv: photovoltaic vuam strips tau hloov kho nyob rau hauv cov kev taw qhia ntawm pem hauv ntej zoo daim phiaj, ultra-nyias, thiab cov duab tsis zoo. Piv txwv li, qhov kev thov rau ultra-nyias welding strips hauv qab 0.08mm thiab tsis xwm yeem seem vuam strips yog nce ib hnub twg. Cov vuam vuam tshuab no yuav tsum muaj qhov tseeb ntawm qhov tseeb thiab kev kam rau siab tswj lub peev xwm ntawm lub tshuab dov, thiab cov tsoos dov mills yog qhov nyuaj rau hloov mus rau. Piv txwv li, cov khoom tshiab xws li HJT thiab TOPCon yuav tsum tau vuam strips nrog thickness kam rau ua tswj nyob rau hauv ± 0.005mm, uas tsav photovoltaic tuam txhab uas muag tshem tawm cov tsoos khoom siv thiab yuav tshiab dov mills nrog high-precision rolling muaj peev xwm. Tsis tas li ntawd, qhov kev thov rau kev txuag hluav taws xob thiab txo tus nqi ntawm cov vuam sawb ntau lawm kuj tau ua rau kev ua haujlwm ntawm dov mills. Piv txwv li, Jiangsu Youjuan's photovoltaic vuam sawb dov zeb txo rolling zog noj los ntawm 25% los ntawm ib tug servo tswj system. Cov kev txuag hluav taws xob rolling mills no tuaj yeem pab cov lag luam txo cov nqi tsim khoom thiab yuav dhau los ua lub hauv paus hauv kev ua lag luam, tsav qhov kev thov rau kev hloov khoom dua tshiab.

       Kev nrawm ntawm kev hloov pauv hauv tsev thiab kev cia siab dav ntawm cov khoom siv hauv zos: Yav dhau los, high-end photovoltaic strip dov mills tau monopolized los ntawm European thiab Asmeskas hom rau lub sijhawm ntev. Tsis tsuas yog tus nqi ntawm ib chav tsev ntau dua 50% siab dua li cov khoom siv hauv tsev, tab sis lub sijhawm xa khoom kuj tseem ntev li 45-60 hnub, thiab nws tseem muaj kev cuam tshuam rau kev hloov pauv hauv cov khoom siv thoob ntiaj teb. Nyob rau hauv xyoo tas los no, domestic dov zeb tshuab tau ua sai sai, mus txog thoob ntiaj teb qib siab nyob rau hauv precision, zog efficiency, thiab lwm yam. Piv txwv li, domestic dov mills tuaj yeem ua tiav kev tswj ntawm vuam sawb thickness kam rau ua ± 0.005mm, nrog lub zog siv li ntawm 25% qis dua cov khoom siv txawv teb chaws, thiab tus nqi tsuas yog 60% -70% ntawm cov khoom siv txawv teb chaws. Lub voj voog xa khoom luv luv rau 20-30 hnub. Nyob rau tib lub sijhawm, cov tuam txhab tsim khoom lag luam tseem tuaj yeem muab cov kev pabcuam customized, thiab tuaj yeem muab cov kev daws teeb meem tsis pub dhau 3 hnub los hloov kho cov khoom sib txawv ntawm cov vuam strips. Cov txiaj ntsig zoo no ua rau cov khoom siv hluav taws xob hauv tsev photovoltaic strip dov mills maj mam hloov cov khoom siv txawv teb chaws, thiab lawv cov kev lag luam sib koom hauv kev lag luam hauv tsev thiab thoob ntiaj teb xav tias yuav nce ntxiv mus ntxiv rau yav tom ntej.

        Cov ntsiab lus mob hauv kev lag luam yuav tsum tau kho sai sai, thiab cov khoom siv zoo tshaj plaws tau ntsib txoj hauv kev txhim kho. Tam sim no, 80% ntawm cov tuam txhab me thiab nruab nrab hauv kev lag luam photovoltaic vuam sawb cia siab rau cov tsoos dov mills, uas muaj teeb meem xws li kev siv hluav taws xob siab, tsis tshua muaj txiaj ntsig, thiab homogenization loj. Qee cov tuam txhab siv hluav taws xob siv hluav taws xob yog 20% ​​-30% siab dua li cov cuab yeej siv siab heev, thiab cov khoom siv vuam vuam yog tsawg dua 85%. Tsis tas li ntawd, ib puag ncig cov cai tseem yuam cov tsoos dov mills uas muaj kuab paug siab thiab siv zog kom tawm hauv kev ua lag luam. Nyob rau hauv cov ntsiab lus no, photovoltaic sawb vuam thiab dov zeb manufacturers nrog lub zog-txuag, txo nqi, high-precision, thiab customization peev xwm tsis tau tsuas yog daws kev lag luam mob cov ntsiab lus, tab sis kuj pab me me thiab nruab nrab manufacturers raws li ib puag ncig tiv thaiv thiab ntau lawm xav tau kev pab. Kev ua lag luam kev lees txais ntawm cov khoom siv zoo li no yuav nce ntxiv, thiab lawv daim ntawv thov scenarios yuav nthuav dav ntxiv los ntawm cov tuam txhab photovoltaic strip vuam cov lag luam mus rau ntau cov tuam txhab me thiab nruab nrab.
