Luv luv Analysis ntawm Kev Txhim Kho Ntawm Photovoltaic Stacking Technology

Stacked Gate yog lub platform thev naus laus zis uas tuaj yeem txuag nyiaj thiab txhim kho kev ua haujlwm zoo

Cov qauv hluav taws xob ntawm cov roj teeb ib txwm muaj yog cov phiaj xwm pabcuam + daim phiaj tseem ceeb + vuam ribbon. Cov kab sib koom ua ke tshem tawm cov ntsiab lus tseem ceeb, cov phiaj xwm sib koom ua ke thiab vuam ribbon, thiab siv cov kab hluav taws xob triangular conductive thiab cov noob txheej rau kev coj ua. Cov kab sib koom ua ke muaj cov yam ntxwv ntawm kev ua haujlwm qis, txuag nyiaj, txhim kho kev ua haujlwm, thiab platformization. thiab lwm yam zoo.

(1) Tam sim no tsis tas yuav kis kab rov tav, tab sis tsuas yog yuav tsum tau xa mus ntev. Txoj kev txav mus los ua luv luv thiab qhov tsis kam ua me me, yog li ua kom muaj zog tivthaiv thiab txo cov nyiaj paste noj.

(2) Ultra-nplua daim duab peb sab conductive xov hlau nrog ultra-siab nto reflectivity tuaj yeem txo qhov sib npaug ntawm lub teeb-shielding cheeb tsam ntawm lub roj teeb saum npoo kom tsawg dua 1%. Peb cia siab tias lub zog ntawm cov kab sib koom ua ke + TOPCon cov khoom tuaj yeem nce los ntawm 630W rau 655W tam sim no (2382mm * 1134mm version hom tivthaiv), uas tuaj yeem ua kom muaj txiaj ntsig los ntawm 25-30W.

Gate stacking yog lub platform thev naus laus zis, uas tuaj yeem siv tau los ntawm TOPCon, HJT, thiab BC, tab sis TOPCon thiab BC xav tau rooj vag stacking ntau dua. Raws li peb cov kev suav, BCTOPCon rooj vag stacking muaj qhov tseem ceeb tshaj plaws ntawm cov nyiaj txo qis ntawm li 5 feeb / WHJT siv 0BB+ 30}% nyiaj-coated tooj liab tuaj yeem ua tiav lub hom phiaj xav tau, thiab lub rooj vag stacked tuaj yeem kuj daws qhov teeb meem shading ntawm TOPCon ob chav poly.

Conductive Wire Alignment yog txheej txheem nyuaj, thiab cov cuab yeej sib tsoo yog qhov tseem ceeb. Cov txheej txheem ntws ntawm daim phiaj stacking yog npaj cov noob txheej, npaj cov kab hluav taws xob daim duab peb sab, thiab txuas cov kab hluav taws xob daim duab peb sab thiab cov noob txheej.

(1) Cov txheej txheem luam ntawv: Cov kev xav tau ntawm daim phiaj sib dhos ntawm cov qauv electrode ntawm lub roj teeb ntawm tes yog qis dua li cov roj teeb li niaj zaus, thiab cov kab sib chaws kab morphology (silver paste) npo thiab cov khoom siv tuaj yeem cuam tshuam.

(2) Daim duab peb sab conductive hlau: Shichuang daim duab peb sab conductive hlau muaj qhov zoo dua qhov xav tau los ntawm kev tsim cov duab zoo dua thiab cov khoom siv saum npoo. Lub kaum sab xis yog 59-61 degrees, thiab peb R lub kaum sab xis yog tswj nyob rau hauv qhov ntau ntawm<15um. The arc transition area accounts for a small proportion and the reflective efficiency is high. Silver aluminum is used as the reflective coating. In the visible light range, metal Ag and AI are the two metals with the highest reflectivity. At the same time, low-temperature welding can also reduce the risk of hidden cracks.

(3) Vuam: Yuav ua li cas kom sai thiab raug "pawg" cov xaim hluav taws xob mus rau cov noob txheej yog qhov nyuaj. Qhov dav ntawm cov pa roj carbon monoxide feem ntau yog siab tshaj 0.2mm, thiab qhov dav ntawm cov xaim hluav taws xob feem ntau yog qis dua 0.15mm, yog li qhov sib xws ntawm vuam kev taw qhia yog qhov nyuaj rau tswj. Nyob rau tib lub sij hawm, finer specifications kuj yuav ua rau kom lub curvature ntawm tin txheej nyob rau hauv qab ntawm cov conductive hlau. Hauv qab tin nto yog ib qho arc, uas yooj yim rau qaij thiab tig sab laug thiab sab xis, ua rau qhov nyuaj ntawm vuam.

Nyob rau hauv 0-1 Theem Ntawm Kev Lag Luam, Cov Khoom Siv thiab Cov Khoom Siv yuav tsum tau txo tus nqi ntxiv.

(1) Economy efficiency: Peb ntseeg hais tias tus nqi ntawm cov ntaub ntawv thiab cov cuab yeej muaj kuj siab nyob rau hauv tam sim no me me-scale zus tau tej cov daim phiaj. Yav tom ntej, kev tsim khoom loj yuav tsum txo tus nqi ib watt los ntawm 2-4 xees piv nrog SMBB thiab 0BB.

(2) Daim ntawv thov scenarios: Tam sim no, daim phiaj xyab tuaj yeem ua kom lub zog ntawm lub module los ntawm 25-30W. Qhov tseem ceeb yog qhov kev tsim qauv tsim qauv ntawm daim duab peb sab conductive hlau tuaj yeem ua rau muaj qhov cuam tshuam thib ob ntawm qhov teeb meem hnub ci.

Txawm li cas los xij, nyob rau hauv qhov xwm txheej ntsug teeb tsa, qhov teeb meem hnub ci feem ntau yog nyob rau ntawm lub kaum sab xis, thiab lub zog nce ntawm cov kab sib koom ua ke yog nyob ntawm qhov chaw uas lub tilted ntsia hnub ci yog xwm txheej ntawm lub kaum sab xis. Yog li ntawd, nyob rau hauv qhov tseeb daim ntawv thov scenario, lub hwj chim nce nyhuv ntawm stacked daim phiaj module tej zaum yuav luv nqi rau ib tug tej yam.

(3) Industrialization kev vam meej: Lub tripartite kev koom tes ntawm Tongwei Co., Ltd., Jingsheng Electromechanical Co., Ltd., thiab Shichuang Zog yuav tsum ceev lub industrialization ntawm stacked kab sib chaws. Peb ntseeg hais tias cov kab sib koom ua ke yog qhov tseem ceeb tshaj rau TOPCon vim tias nws nyuaj rau TOPCon siv tooj liab slurries los txo cov nqi metallization, thaum HJT tuaj yeem ua tiav cov nqi metallization tsawg heev los ntawm 0BB + silver-clad tooj liab thev naus laus zis.

Los ntawm qhov kev vam meej tam sim no, lub fwj loj tshaj plaws nyob rau hauv kev lag luam ntawm cov kab sib chaws nyob hauv cov khoom siv thiab cov khoom siv (daim duab peb sab conductive xov hlau), xws li cov txheej txheem khiav, cov khoom tawm los, thiab kev lag luam. Shichuang tam sim no muaj 1GW ntawm dual Polo + stacked grid TOPCon modules hauv kev ua haujlwm.

Nyob rau hauv lub neej yav tom ntej, raws li stacked grid modules yog loj-tsim thiab khiav-los ntawm + cov nqi khoom yog tsis tu ncua optimized, muaj feem xyuam rau cov khoom thiab cov khoom siv yuav tsum tau txais txiaj ntsig los ntawm kev nthuav dav ntawm stacked kab sib chaws. Peb kwv yees tias qhov chaw lag luam nruab nrab txhua xyoo rau cov khoom siv yog kwv yees li RMB 13 billion thiab qhov nruab nrab txhua xyoo kev lag luam chaw rau cov khoom siv yog kwv yees li RMB 7 billion.
