TOPCon, BC, lossis HJT hnub ci vaj huam sib luag- kuv yuav xaiv qhov twg? - Kev paub

TOPCon, BC, lossis HJThnub ci vaj huam sib luag– Kuv yuav tsum xaiv qhov twg?

Qhov no yog tej zaum ib lo lus nug feem ntau hauv hnub ci tam sim no. Peb xyoos dhau los tsis muaj ntau txoj kev xaiv los ua - PERC modules ntau dua lossis tsawg dua qhov kev xaiv nkaus xwb. Niaj hnub no, qhib yuav luag txhua lub khw muag khoom nplooj ntawv thiab koj yuav pom TOPCon, BC, thiab HJT zaum ntawm ib sab, txhua tus nrog cov ntaub ntawv ntom ntom, thiab txhua qhov kev muag khoom suab zoo ib yam: "siab dua," "qis degradation," "ntau zog tawm los." Qhov ntau koj hnov nws, nws nyuaj rau txiav txim siab - tshwj xeeb vim qhov no yog 20-25 xyoo kev cog lus.

Qhov tseeb tsis yog ib qho ntawm peb lub thev naus laus zis no yog lub hom phiaj "zoo dua." Txhua qhov zoo dua rau qhov sib txawv. Txhawm rau txiav txim siab zoo, nws yuav pab pib nrog qhov sib cais tiag tiag.

Yuav Ua Li Cas Tiag Peb Lub Tshuab Sib Piv

TOPCon(Tunnel Oxide Passivated Contact) yog tam sim no qhov kev siv thev naus laus zis tshaj plaws, rau qhov yooj yim: nws tuaj yeem hloov kho los ntawm cov kab tsim khoom PERC uas twb muaj lawm es tsis xav tau kev teeb tsa tshiab, uas ua rau thawj peev peev tswj tau thiab cov saw hlau loj. Thaum kawg ntawm 2025, TOPCon suav txog kwv yees li 80% ntawm cov tshiab tshiab ntxiv thoob ntiaj teb cov xov tooj ntawm tes. Nws lub ntsiab tsis muaj zog yog kub coefficient - rau txhua txhua 1℃nce nyob rau hauv kev khiav hauj lwm qhov kub thiab txias, nws poob me ntsis ntau tshaj li ob technologies.

HJT(Heterojunction Technology) siv txoj hauv kev sib txawv: ib txheej ntawm amorphous silicon zaj duab xis coats ob sab ntawm crystalline wafer, thiab cov txheej txheem tsim ua haujlwm qis dua 200 degree, uas ua rau muaj kev ntxhov siab tsawg dua ntawm silicon nws tus kheej. Nws cov txiaj ntsig tseem ceeb yog nyob rau hauv qhov kub thiab txias coefficient - ua ke, cov no txhais tau tias HJT qhov tseeb - ntiaj teb kev ua tau zoo nyob rau hauv kub, siab - diffuse- lub teeb ib puag ncig feem ntau outpaces dab tsi cov xov tooj ntawm cov xov tooj ua tau zoo ib leeg yuav hais. Kev lag luam tawm -tawm yog txheej txheem ntau dua thiab ntau dua cov nyiaj muab tshuaj txhuam, uas feem ntau thawb tus nqi ib -watt tus nqi siab dua, nrog tus nqi them tiag tiag nyob ntawm seb nyiaj ntau npaum li cas-coated- tooj liab thiab lwm yam nqi-txo cov tswv yim uas cov chaw tsim khoom tau txais yuav.

BC(Kev Sib Txuas Rov Qab, suav nrog cov kev hloov pauv tshwj xeeb xws li IBC, ABC, thiab HPBC) txav txhua qhov hluav taws xob tiv tauj mus rau tom qab ntawm lub xov tooj ntawm tes, tawm hauv pem hauv ntej kom tsis muaj kab sib chaws - kab shading - pom kev huv, thiab nrog lub siab tshaj plaws theoretical efficiency qab nthab ntawm peb. Nws qhov tsis zoo yog qhov kev tsim khoom ntau dua thiab muaj peev xwm qeeb dua - nce, yog li cov khoom siv tam sim no tau tsom mus rau cov tuam txhab me me, uas ua rau cov kev xaiv qis dua.

Muab cov ntsiab lus tseem ceeb ntawm ib sab ua rau kev sib piv yooj yim ua raws li:

Kev sib piv	TOPCon	HJT	BC (IBC/ABC/HPBC)
Pawg- ntau lawm module efficiency	~24.5%–25.5%	~ 24% -26% (qee yam khoom 26% +)	~ 24% -25%, cov khoom sab saum toj ze li 25.5%
Kub coefficient	-0.29% rau -0.32% / degree	-0.24% rau -0.26% / degree	-0.25% rau -0.27% / degree
Bifaciality	~70%–80%	~85%–95%	Nws txawv ntawm variant; qee cov qauv yog monofacial
Thawj - xyoo degradation	Tsawg dua lossis sib npaug li 1%	Tsawg dua lossis sib npaug li 1%, qee yam khoom qis dua	Tsawg dua lossis sib npaug li 1%
Kev degradation txhua xyoo	~ 0.30% - 0.40% / xyoo	~ 0.25% - 0.30% / xyoo	~ 0.25% - 0.30% / xyoo, ntawm cov lag luam qis tshaj

(Cov kab no muaj feem cuam tshuam txog kev lag luam cov nuj nqis. Qhov tseeb specs sib txawv los ntawm cov chaw tsim khoom thiab cov khoom tsim tawm batch - ib txwm lees paub tawm tsam cov ntaub ntawv tshwj xeeb ntawm cov khoom ua ntej kev yuav khoom.)

Efficiency thiab Degradation: Cov lej tsuas muaj teeb meem hauv cov ntsiab lus

Saib ntawm cov lej ua haujlwm ib leeg tuaj yeem ua yuam kev. Piv txwv li, hauv tib hom 60- xovtooj ntawm tes, BC module yuav raug ntsuas ntawm 550W, HJT module ntawm 545W, thiab TOPCon module ntawm 530W. Qhov sib txawv zoo li me me ntawm daim ntawv, tab sis nyob ntawm lub ru tsev thiab thaj chaw huab cua, qhov tshwm sim tiag tiag hauv ntiaj teb tuaj yeem zoo li txawv - qee zaum txawm rov qab los.

Ib daim duab qhia ntau dua yog qhov ntev - lub sij hawm degradation nkhaus. Ob peb xyoos ntawm - cov ntaub ntawv hauv ntiaj teb no tam sim no muaj nyob thoob plaws kev lag luam:

Technology	Thawj - xyoo degradation	Tom qab txhua xyoo degradation	Kwv yees lub zog tuav ntawm xyoo 25
TOPCon	Tsawg dua lossis sib npaug li 1%	~ 0.30% - 0.40% / xyoo	~88%–90%
HJT	Tsawg dua lossis sib npaug li 1%, qee yam khoom qis dua	~ 0.25% - 0.30% / xyoo	~90%–92%
BC	Tsawg dua lossis sib npaug li 1%	~ 0.25% - 0.30% / xyoo	~90%–92%

Vim hais tias HJT hlwb feem ntau yog boron-dawb, lawv zam lub teeb-induced degradation los ntawm boron-oxygen complexes, muab lawv ib tug comparatively flatter degradation nkhaus; BC ua zoo ib yam. Ua ke ntau tshaj 25 xyoo, cov feem pua ntawm cov ntsiab lus no txhais ua qhov tseeb, ntsuas qhov sib txawv ntawm tag nrho cov txiaj ntsig hluav taws xob - ib yam uas tseem ceeb tshaj plaws rau kev lag luam thiab kev siv hluav taws xob- cov phiaj xwm ntsuas qhov ntsuas tus nqi hluav taws xob (LCOE) yog qhov ntsuas tseem ceeb. Nws tsis yog tus lej koj yuav tsum txiav txim tsuas yog hnub -ib wattage.

Uas tau hais tias, muaj cov piv txwv uas tsim nyog sau cia: qee qhov thib peb -kev sim sab nraud hauv cov suab puam huab cua- qhov chaw sov muajqhia HJT modulesunderperforming expectation ntawm peb- xyoo degradation nyob rau hauv siab kub thiab irradiance tej yam kev mob. Qhov kev tshem tawm yog tias qhov ntsuas kub zoo tsis tau lees paub qhov zoo dua hauv txhua qhov kev ua haujlwm - nws tsim nyog kuaj xyuas cov ntaub ntawv huab cua hauv zos thiab cov chaw tsim khoom lag luam es tsis yog cia siab rau cov ntaub ntawv cov ntaub ntawv ib leeg.

Cov huab cua kub: Qhov twg Kub Coefficient dhau los ua qhov txiav txim siab

Rau tej yaam num nyob rau hauv cov cheeb tsam kub tsis tu ncua - Southeast Asia, Middle East, qaum teb Australia, los yog domestically nyob rau hauv tej chaw xws li Hainan thiab Tuam Tshoj lub Turpan Basin, uas module khiav hauj lwm kub tsis tu ncua tshaj 45℃thiab tuaj yeem ncav cuag 60℃nyob rau lub caij ntuj sov - qhov ua tau zoo ntawm qhov kub thiab txias coefficient tau txais kev nthuav dav.

Kev lag luam kwv yees qhia tias nyob rau ntawm qhov ntsuas kub ntawm 65 degree, txhua txhua 0.05% /℃qhov sib txawv ntawm qhov kub thiab txias coefficient txhais mus rau kwv yees li 2-3 feem pua ntawm qhov sib txawv ntawm lub zog txhua xyoo:

Hom huab cua	Tej cheeb tsam	Module kev khiav hauj lwm kub	Kev cuam tshuam ntawm qhov kub thiab txias coefficient	Zoo dua -tsim technology
Kub, siab irradiance	Southeast Asia, Middle East, qaum teb Australia, Hainan, Turpan Basin	Feem ntau saum 45 degree, lub caij ntuj sov peaks 60℃+	Qhov tseem ceeb - qhov sib txawv txhua xyoo tawm mus txog 3%–5%	HJT / BC nyiam
Kev nyab xeeb nruab nrab	Northern China, Northern/Central Europe	Feem ntau hauv qab 40 degree	Tsawg - qhov sib txawv feem ntau qis dua 1%	TOPCon muab tus nqi zoo dua
Cloudy, diffuse-teeb- hnyav	ntug hiav txwv dej, lub nroog los nag	Nruab nrab kub, siab diffuse teeb qhia	Bifaciality tseem ceeb tshaj qhov kub coefficient	HJT qhov kev nce qib bifacial tau tshaj tawm

Qhov no yog vim li cas, hauv kev lag luam kub xws li US "Sun Belt" (Arizona, Nevada, Texas, Florida) thiab Is Nrias teb Gujarat, cov neeg yuav khoom txaus siab lees txais tus nqi them rau HJT lossis BC - tus nqi nce siab ntxiv tau rov qab los ntawm cov zis ntau dua thaum lub sijhawm siab tshaj -cov sijhawm kub. Hloov pauv, nyob rau hauv huab cua kub ntau dua, TOPCon qhov kub thiab txias -coefficient tsis zoo NW nyuam qhuav tshwm sim nyob rau hauv kev xyaum, yog li tus nqi rhiab heev yuav dominate thiab TOPCon tus nqi proposition stands ntau.

Rov qab rau Kev nqis peev: Nws tsis yog tus nqi ib Watt xwb

Thaum tib neeg tau daig ntawm kev xaiv module, lawv nyiam kho ntawm tus nqi ntawm lub vaj huam sib luag nws tus kheej. Tab sis qhov tseeb txiav txim siab lub sij hawm them rov qab yog tus nqi qauv ntawm tus nqitag nrho qhov system- rau- tus nqi watt tsuas yog ib qho sib txawv ntawm ob peb.

High-wattage modules (cov chav kawm 700W–800W tam sim no muaj nyob rau hauv kev ua lag luam) coj ib qho kev pab cuam feem ntau- saib tsis taus: qhov nyiaj qis dua- ntawm -system (BOS) tus nqi - racking, thaiv, thiab kev teeb tsa ua haujlwm. Siv 15kWp installation ua piv txwv:

Module zog	Module yuav tsum tau	Cov ntsiab lus mounting txheeb ze	Kev xaim & kev nkag tau yooj yim
450W	~ 33 units	Lub hauv paus	Lub hauv paus
550W	~ 27 units	~ 18% tsawg dua	Txo
800W	~ 19 units	~ 42% tsawg dua	Tsawg heev

Yuav luag ib nrab ntawm cov qauv suav suav txhais tau hais tias tsawg dua cov ntsiab lus txuas, kev sib txuas luv dua, kev nkag mus rau lub ru tsev tsawg dua, thiab qis dua - lub sij hawm tu ncua complexity. Rau kev lag luam tej yaam num uas txwv lub ru tsev cheeb tsam, los yog nyob rau hauv lub installation nyob rau hauv uas usable qhov chaw yog inherently nruj, cov installation thiab txij nkawm kev txuag yog feem ntau muaj nuj nqis rau cov nyiaj them rov qab xam dua tus nqi sib txawv ntawm module technologies.

Cov specs qhia ncaj qha mus rau ob qhov xwm txheej uas tau tham saum toj no: thawj zaug, lub ru tsev - cheeb tsam- txwv txoj haujlwm xav tau tsawg dua modules mus rau lub hom phiaj muaj peev xwm, thiab thib ob, qhov chaw uas muaj huab cua kub lossis siab diffuse lub teeb uas bifaciality thiab kub coefficient txhais ua lub zog tiag tiag - tawm los. Txawm hais tias nws yog qhov haum thaum kawg rov qab los rau koj tus kheej lub ru tsev thiab cov huab cua hauv zos.

Daim Ntawv Qhia Kev Txiav Txim: Sib piv cov thev naus laus zis rau koj qhov project

Es tsis txhob sim sau cov npe ntawm cov specs, nws muaj txiaj ntsig zoo dua los ua haujlwm rov qab los ntawm koj qhov project tus yam ntxwv tiag tiag.

Cov peev nyiaj- tsom, huab cua nruab nrab, qhov chaw dav ru tsev:TOPCon tam sim no yog qhov zoo tshaj plaws - kev xaiv sib npaug - cov khoom lag luam paub tab, pob tshab tus nqi, thiab tus nqi muaj zog tshaj plaws rau cov khoom siv hluav taws xob feem ntau - nplai cov nroj tsuag thiab cov qauv kev lag luam uas tsis xav tau qhov siab tshaj ntawm -watt efficiency.

Kev nyab xeeb kub, lossis ntev - lub sij hawm (20+ xyoo) yield yog qhov tseem ceeb:HJT qhov kub thiab txias coefficient thiab bifaciality zoo txhais mus rau tiam tiag tiag, ua rau tus nqi tsim nyog them - tshwj xeeb tshaj yog nyob rau hauv cov chaw uas muaj qhov sib txawv loj lossis qis - lub teeb pom kev, xws li pos huab lossis los nag hauv ntug dej hiav txwv, qhov chaw siab dua bifaciality ntes ntau lub teeb pom kev los ntawm sab nraub qaum.

Lub ru tsev cheeb tsam yog ib qho nyuaj thiab koj yuav tsum tau ua kom muaj peev xwm ua tau kom siab tshaj plaws:Ntawm no, lub zog ceev ntawm ib qho module tseem ceeb tshaj qhov siv tshuab nws tus kheej. Siab- fais fab modules siab tshaj 700W - seb TOPCon los yog HJT - txo qis module suav thiab txo qis racking thiab nqi zog. Qhov no yog qhov xwm txheej uas cov khoom xws li Jingsun 800W (24.39% efficiency, 95% bifaciality, nyob rau hauv 0.3% txhua xyoo degradation) zoo li tau teev tseg - tej yaam num uas "watts ib square meter" outweighs "tus nqi ib watt" raws li qhov kev txiav txim.

Chasing peak efficiency, pob nyiaj siv tsis yog qhov txwv, thiab kev muab khoom yog txhim khu kev qha:BC yog tsim nyog xav txog - nws muaj qhov siab tshaj plaws theoretical efficiency qab nthab thiab qis tshaj degradation ntawm peb, txawm hais tias lub teb ntawm cov neeg muag khoom tseem nqaim, yog li paub meej tias lub sij hawm txhuas thiab tom qab - cov nqe lus muag ua tib zoo ua ntej cog lus.
