N-hom PV Modules Yuav Tau Txais Lub Caij Nyoog

Txij li xyoo no, photovoltaic module manufacturers tau nce ntau lawm. Sib txawv los ntawm yav dhau los nce ntawm P-hom PERC module ntau lawm kab muaj peev xwm, nyob rau theem tam sim no, lub peev xwm tsim tawm tshiab tau npaj los ntawm kev lag luam yog tsom rau N-hom modules, feem ntau sawv cev los ntawm TOPcon thiab heterogeneous. Nws cia siab tias N-hom muaj peev xwm tsim tau los ntawm lub taub hau PV module lag luam yuav tshaj 50 lab kW xyoo no. Nyob rau hauv kev pom ntawm kev lag luam, PV modules nyob rau hauv ib lub sij hawm ntawm kev ceev thev naus laus zis iteration rau N-hom modules uas muaj txiaj ntsig zoo dua li P-hom PERC hloov dua siab tshiab thiab tsim hluav taws xob ntau dua.

N-hom tshuab tau muaj nyob rau lub sijhawm ntev. Vim li cas PV module technology tau nrawm los ntawm P-hom rau N-hom xyoo no? Yuav ua li cas cov kev hloov pauv technology yuav coj mus rau yav tom ntej kev thov ntawm PV kev ua lag luam? Nyob ib ncig ntawm cov teeb meem no, tus neeg sau xov xwm tau tshawb xyuas kev xam phaj.

Nruam efficiency breakthrough

P-hom tivthaiv yog sawv cev los ntawm PERC thev naus laus zis, uas yog cov thev naus laus zis tseem ceeb hauv kev ua lag luam tam sim no. Nws muaj cov yam ntxwv ntawm tus nqi qis thiab kev hloov pauv tsis zoo. N-hom tivthaiv kev nthuav dav thev naus laus zis feem ntau suav nrog TOPcon thiab heterojunction, uas muaj cov yam ntxwv ntawm tus nqi siab thiab kev hloov pauv siab piv nrog PERC thev naus laus zis. Kev cuam tshuam los ntawm cov nqi peev thiab lwm yam, P-hom PERC Cheebtsam tau pom dav los ntawm kev ua lag luam vim lawv cov nqi ua haujlwm siab, suav txog qhov tseem ceeb ntawm txoj haujlwm hauv ntiaj teb kev xav tau. Tab sis qhov ntawd yog ntsiag to hloov.

"Tam sim no, PV kev lag luam yog nyob rau hauv lub qhov rais ntawm technological iteration. Ntawm ib sab, nrog rau txoj kev loj hlob ntawm P-type PERC Cheebtsam maj mature, nws conversion efficiency yog ze rau theoretical txwv. Ntawm qhov tod tes, N-hom Cheebtsam. tab tom qhib txoj hauv kev vim tias lawv qhov kev hloov pauv theoretical efficiency qab nthab siab dua P-hom PERC Cheebtsam. " Chint tshiab zog Technology Co., Ltd. Tus Lwm Thawj Coj Huang Haiyan tau hais rau cov neeg sau xov xwm.

Nyob rau hauv thawj ib nrab ntawm lub xyoo no, Tuam Tshoj lub photovoltaic siv lead ua silicon cell soj ntsuam efficiency cov ntaub ntawv tau tawg xya zaug, tsib ntawm uas yog N-hom hlwb, raws li cov ntaub ntawv los ntawm Tuam Tshoj Photovoltaic Industry Association. Qhov kev hloov pauv siab tshaj plaws ntawm P-hom PERC hlwb yog 24.5%, thaum lub siab tshaj plaws conversion efficiency ntawm N-hom heterojunction hlwb tau mus txog 26.5%.

Huang Haiyan ntseeg tias nyob rau hauv cov ntsiab lus saum toj no, nws xav tias yav tom ntej kev thov rau N-hom khoom yuav nce ntxiv, kev ua lag luam yuav maj mam nce. "Tam sim no, peb cov N-hom TOPcon roj teeb thiab cov khoom lag luam yog nyob rau hauv ntau lawm. Piv nrog rau cov khoom PERC, TOPcon cov khoom muaj kev sib tw hauv ob qho tib si kev paub tab thiab cov nqi ua haujlwm. Peb kuj muaj cov kav dej ntawm cov thev naus laus zis tshiab, xws li heterojunctions, uas tau npaj txhij. rau yav tom ntej."

Tus nqi pheej yig dua

Nrog rau qhov zoo ntawm N - cov khoom lag luam maj mam tshwm sim, nws txoj kev nce qib kuj tseem nrawm dua. Raws li kev txheeb cais ntawm Tuam Tshoj Photovoltaic Industry Association, N-hom cell expansion tej yaam num account rau 1/3 ntawm tag nrho cov peev xwm ntawm cell expansion. Nyob rau tib lub sijhawm, cov tuam txhab lag luam tau tshaj tawm N-hom khoom tshiab. Ntau lub lag luam hauv nruab nrab, xws li CGN Tshiab Zog, Huadian Group, CNNC Huneng thiab Lub Xeev Lub Tuam Txhab Nyiaj Txiag Tuam Txhab, tau qhib N-hom tivthaiv kev sib tw, thiab cov kev thov tshaj tawm rau N-hom Cheebtsam tau tshaj 4 lab kW, plaub zaug. nce piv nrog 2021.

Cov txiaj ntsig ntawm N-hom thev naus laus zis yuav tshwm sim thaum kawg ntawm kev nce hauv cov txiaj ntsig ntawm cov chaw nres tsheb fais fab. Qee lub tuam txhab hauv kev lag luam kwv yees tias yog cov qauv siv dav dav siv, tus nqi davhlau ya nyob twg ntawm qhov chaw nres tsheb fais fab photovoltaic tuaj yeem raug txo los ntawm 6% -7% thaum twg qhov kev hloov pauv ntawm tes tau nce 1%. Hais txog tus nqi, nws xav tias nyob rau hauv ob xyoos tom ntej no, tus nqi ntawm cov khoom siv ntawm N-hom roj teeb tuaj yeem raug txo los ntawm laminating, thiab cov nqi tsim khoom kuj tseem tuaj yeem txo qis dua los ntawm cov khoom siv hauv zos.

Huang Haiyan pom zoo. "Qhov zoo dua ntawm N-hom TOPcon thev naus laus zis nyob rau hauv qhov kev cia siab ntawm kev txo qis wafer thickness. Tam sim no, wafer thickness ntawm P-hom PERC cov khoom yog nyob ib ncig ntawm 150-155 microns, thiab tej zaum nws yuav ua tau {{3} } microns yav tom ntej "Peb lub zeem muag rau N-hom TOPcon yog kom tau cov wafer tuab mus txog li 100-110 microns."

Nyob rau tib lub sijhawm, Huang Haiyan tau taw qhia tias qhov kev hloov pauv tsis ntev los no hauv PV cov saw hlau cov nqi kuj tau muab kev txhawb zog rau kev ua lag luam nrawm thiab kev lag luam ntawm N-hom thev naus laus zis. "Tus nqi ntawm silicon nyob rau hauv PV modules yog siab, thiab raws li tus nqi ntawm silicon nce, nws feem ntawm tus nqi yog nce. Qhov iteration los ntawm P-type technology mus rau N-type technology tuaj yeem txhawb kev txo cov khoom siv silicon thiab txo cov khoom siv. Tus nqi nkag no kuj yog ib qho laj thawj tseem ceeb rau kev txhim kho tag nrho hauv kev hloov kho thev naus laus zis hauv kev lag luam xyoo no. "

Kev lag luam nce ntxiv

Raws li cov teb chaws thoob plaws ntiaj teb tau teeb tsa cov hom phiaj ntawm cov pa roj carbon monoxide, kev thov rau kev teeb tsa photovoltaic zog tau nce siab, Huang tau hais. Tsis tas li ntawd, txoj kev loj hlob ntawm kev lag luam photovoltaic tau dhau los ua neeg paub tab, thiab cov neeg siv khoom xav tau rau photovoltaic modules kuj yog nyob rau hauv txoj kab nrog kev hloov dua siab tshiab thiab kev tsim hluav taws xob ntau dua, N-hom thev naus laus zis yuav ua rau kev lag luam dav dav.

"Tam sim no, kev lag luam peev yog qhov zoo rau kev lag luam tshiab hluav taws xob sawv cev los ntawm photovoltaic." Nyob rau hauv cov ntsiab lus ntawm tag nrho cov nqi hloov pauv ntawm PV kev lag luam saw, cov peev txheej rhiab heev ntawm cov phiaj xwm PV faib yog qis dua li ntawm centralized PV, yog li nws yuav ua rau muaj kev txhim kho ntau dua." "Ob qho kev lag luam hauv tsev thiab kev lag luam tawm txawv teb chaws qhia qhov kev thov muaj zog rau kev teeb tsa," Huang tau hais.

"Tshwj xeeb nyob rau hauv kev lag luam txawv teb chaws, qhov twg tus nqi hluav taws xob tau nce siab nyob rau hauv Tebchaws Europe thiab lwm qhov chaw vim muaj kev cuam tshuam ntawm thaj chaw, ntau thiab ntau tus neeg siv tab tom nrhiav kom txo lawv cov nuj nqis txhua hnub los ntawm kev txhim kho PV. Tib lub sijhawm, vim muaj kev hloov pauv, kev lag luam xws li raws li Is Nrias teb thiab Brazil tseem tab tom qhia qhov kev thov muaj zog, nrog PV kev teeb tsa tau nce siab rau xyoo no. " "Huang Haiyan tau hais.

PVInfoLink, lub koom haum thib peb ntawm kev lag luam, taw qhia tias nyob rau xyoo no International Solar qhia hauv Munich, Lub teb chaws Yelemees, ntau tus neeg tuaj koom tau nthuav tawm N-hom modules. Kev ua lag luam nyob sab Europe yuav yog lub ntiaj teb outpost rau N-hom Cheebtsam, tau txais txiaj ntsig los ntawm cov thev naus laus zis tshiab, kev lees txais tus nqi siab, thiab nce kev thov rau cov khoom siv nrog cov pa roj carbon tsawg. Nyob rau hauv 2023, N-hom khoom xa tuaj yuav tsum loj hlob.
