Nrog rau kev nce qib ntawm cov cuab yeej technology thiab txo cov nqi khoom, lub ntiaj teb photovoltaic kev lag luam nplai yuav loj hlob sai heev, thiab feem ntau ntawm cov khoom lag luam n-hom hauv ntau lub lag luam kuj tseem nce ntxiv.Ntau lub tsev kawm ntawv kwv yees tias los ntawm 2024, lub peev xwm tshiab ntawm lub ntiaj teb photovoltaic tsim hluav taws xob yuav tsum tshaj 500GW (DC), thiab feem ntau ntawm cov n-hom roj teeb yuav txuas ntxiv mus ntxiv rau txhua lub hlis twg, nrog rau kev xav tau ntawm ntau dua 85% los ntawm kawg ntawm lub xyoo.
Vim li cas cov khoom n-hom tuaj yeem ua tiav cov txheej txheem thev naus laus zis sai sai?Cov kws tshuaj ntsuam xyuas los ntawm SBI Consultancy tau taw qhia tias, ntawm ib sab, cov peev txheej hauv av tau dhau los ua tsawg zuj zus, xav tau kev tsim hluav taws xob huv dua ntawm thaj chaw tsawg;ntawm qhov tod tes, thaum lub hwj chim ntawm n-hom roj teeb Cheebtsam yog nce sai, tus nqi sib txawv nrog p-hom khoom yog maj mam nqaim.Los ntawm qhov kev xav ntawm kev sib tw nqi los ntawm ntau lub tuam txhab hauv nruab nrab, tus nqi sib txawv ntawm np cov khoom ntawm tib lub tuam txhab tsuas yog 3-5 xees / W, qhia txog qhov ua tau zoo.
Cov kws tshaj lij thev naus laus zis ntseeg tias qhov tsis tu ncua ntawm cov cuab yeej siv peev, kev txhim kho hauv cov khoom lag luam zoo, thiab cov khoom lag luam txaus txhais tau hais tias tus nqi ntawm cov khoom n-hom yuav poob mus ntxiv, thiab tseem muaj txoj hauv kev mus ntev rau kev txo nqi thiab nce kev ua haujlwm. .Nyob rau tib lub sijhawm, lawv hais txog tias Zero Busbar (0BB) thev naus laus zis, raws li txoj hauv kev zoo tshaj plaws los txo cov nqi thiab nce kev ua tau zoo, yuav ua lub luag haujlwm tseem ceeb hauv kev lag luam photovoltaic yav tom ntej.
Saib ntawm keeb kwm ntawm kev hloov pauv hauv cell gridlines, qhov ntxov tshaj plaws photovoltaic hlwb tsuas muaj 1-2 lub ntsiab gridlines.Tom qab ntawd, plaub lub ntsiab gridlines thiab tsib lub ntsiab gridlines maj mam coj txoj kev lag luam sib txawv.Pib txij li ib nrab xyoo 2017, Multi Busbar (MBB) thev naus laus zis tau pib siv, thiab tom qab ntawd tau tsim los rau hauv Super Multi Busbar (SMBB).Nrog rau kev tsim ntawm 16 lub ntsiab gridlines, txoj hauv kev ntawm kev sib kis tam sim no mus rau cov kab hluav taws xob tseem ceeb raug txo, ua kom tag nrho cov khoom siv hluav taws xob tsim hluav taws xob, txo qis kev ua haujlwm kub, thiab ua rau muaj hluav taws xob ntau dua.
Raws li ntau thiab ntau cov haujlwm pib siv cov khoom siv n-hom, txhawm rau txo cov nyiaj siv nyiaj, txo kev cia siab ntawm cov hlau muaj txiaj ntsig, thiab txo cov nqi tsim khoom, qee lub tuam txhab roj teeb tau pib tshawb nrhiav lwm txoj hauv kev - Zero Busbar (0BB) thev naus laus zis.Nws tau tshaj tawm tias cov thev naus laus zis no tuaj yeem txo qis kev siv nyiaj ntau dua 10% thiab ua kom lub zog ntawm ib feem ntau dua 5W los ntawm kev txo qis pem hauv ntej-sab shading, sib npaug rau nce ib qib.
Cov kev hloov hauv tshuab ib txwm nrog kev kho dua tshiab ntawm cov txheej txheem thiab cov khoom siv.Ntawm lawv, stringer raws li cov cuab yeej tseem ceeb ntawm kev tsim cov khoom lag luam muaj feem cuam tshuam nrog kev tsim cov tshuab gridline.Cov kws tshaj lij thev naus laus zis tau taw qhia tias lub luag haujlwm tseem ceeb ntawm stringer yog txhawm rau txuas cov ribbon rau ntawm tes los ntawm cov cua kub kub los ua ib txoj hlua, coj lub luag haujlwm ntawm ob lub hom phiaj ntawm "kev sib txuas" thiab "series txuas", thiab nws cov vuam zoo thiab kev ntseeg tau ncaj qha. cuam tshuam rau lub rooj cob qhia cov txiaj ntsig thiab cov peev txheej ntau lawm.Txawm li cas los xij, nrog kev nce ntawm Zero Busbar thev naus laus zis, cov txheej txheem vuam cov txheej txheem kub ib txwm tau dhau los ua qhov tsis txaus thiab yuav tsum tau hloov sai sai.
Nws yog nyob rau hauv cov ntsiab lus no uas lub Little Cow IFC Direct Film Covering thev naus laus zis tshwm sim.Nws tau nkag siab tias Zero Busbar yog nruab nrog Little Cow IFC Direct Film Npog thev naus laus zis, uas hloov cov txheej txheem kev sib txuas ua ke, ua kom yooj yim rau cov txheej txheem ntawm txoj hlua ntawm tes, thiab ua rau cov kab ntau lawm txhim khu kev qha thiab tswj tau.
Ua ntej, cov thev naus laus zis no tsis siv cov khoom siv hluav taws xob lossis cov nplaum nplaum hauv kev tsim khoom, uas ua rau tsis muaj kuab lom thiab muaj txiaj ntsig zoo hauv cov txheej txheem.Nws kuj zam cov khoom siv downtime los ntawm kev saib xyuas ntawm solder flux lossis nplaum, yog li ua kom lub sijhawm ua haujlwm siab dua.
Thib ob, IFC thev naus laus zis txav cov txheej txheem kev sib txuas ntawm cov hlau mus rau theem laminating, ua tiav cov vuam ib txhij ntawm tag nrho cov khoom.Qhov kev txhim kho no ua rau cov vuam kub zoo sib xws, txo qis qis, thiab txhim kho vuam zoo.Txawm hais tias lub qhov rais hloov qhov kub ntawm lub laminator yog nqaim nyob rau theem no, cov nyhuv vuam tuaj yeem ua kom ntseeg tau los ntawm kev ua kom zoo ntawm cov khoom siv zaj duab xis kom haum rau qhov xav tau vuam kub.
Thib peb, raws li kev lag luam xav tau rau cov khoom siv hluav taws xob loj loj hlob tuaj thiab feem ntau ntawm cov nqi ntawm tes txo qis hauv cov nqi ntawm cov khoom siv, txo cov intercell sib nrug, lossis txawm tias siv qhov tsis zoo, dhau los ua "kev nyiam."Yog li ntawd, cov khoom ntawm tib qhov loj tuaj yeem ua tiav lub zog tso zis ntau dua, uas yog qhov tseem ceeb hauv kev txo qis cov nqi ntawm cov khoom siv silicon thiab txuag cov nqi BOS.Nws tau tshaj tawm tias IFC thev naus laus zis siv cov kev sib txuas hloov tau yooj yim, thiab cov hlwb tuaj yeem muab tso rau ntawm cov yeeb yaj kiab, txo qhov sib nrug ntawm lub cell thiab ua tiav xoom zais cov kab nrib pleb hauv qhov me me lossis qhov tsis zoo.Tsis tas li ntawd, lub vuam ribbon tsis tas yuav tsum tau flattened thaum lub sij hawm tsim cov txheej txheem, txo qhov kev pheej hmoo ntawm cell tawg thaum lub sij hawm lamination, ntxiv kev txhim kho ntau lawm yield thiab tivthaiv kev ntseeg tau.
Thib plaub, IFC thev naus laus zis siv cov vuam vuam ribbon qis qis, txo qhov kev sib tshuam kub kom qis dua 150°C. Qhov kev tsim kho tshiab no txo qis kev puas tsuaj ntawm thermal stress rau cov hlwb, txo cov kev pheej hmoo ntawm cov kab nrib pleb thiab busbar breakage tom qab cell thinning, ua rau nws ntau tus phooj ywg rau nyias hlwb.
Thaum kawg, txij li thaum 0BB hlwb tsis muaj cov kab sib txuas tseem ceeb, qhov tseeb ntawm qhov vuam ribbon yog qhov tsawg, ua rau cov khoom tsim tau yooj yim dua thiab ua haujlwm tau zoo, thiab txhim kho cov txiaj ntsig rau qee qhov.Qhov tseeb, tom qab tshem tawm cov kab hluav taws xob hauv ntej, cov khoom ntawm lawv tus kheej yog qhov zoo nkauj dua thiab tau txais kev lees paub dav dav los ntawm cov neeg siv khoom hauv Tebchaws Europe thiab Tebchaws Meskas.
Nws yog ib qho tsim nyog hais tias lub Little Cow IFC Direct Film Npog thev naus laus zis daws qhov teeb meem ntawm warping tom qab vuam XBC hlwb.Txij li thaum XBC hlwb tsuas muaj gridlines ntawm ib sab, cov pa hluav taws kub-kub welding tuaj yeem ua rau muaj kev kub ntxhov ntawm cov hlwb tom qab vuam.Txawm li cas los xij, IFC siv cov yeeb yaj kiab uas muaj qhov kub thiab txias los npog cov cuab yeej siv los txo cov kev ntxhov siab thermal, uas ua rau cov hlua khi ntawm cov xov tooj ntawm tes tsis sib xws tom qab npog zaj duab xis, zoo heev txhim kho cov khoom zoo thiab kev ntseeg siab.
Nws tau nkag siab tias tam sim no, ntau lub tuam txhab HJT thiab XBC tau siv 0BB thev naus laus zis hauv lawv cov khoom, thiab ntau lub tuam txhab TOPCon tseem tau qhia txog kev txaus siab rau cov thev naus laus zis no.Nws cia siab tias nyob rau hauv ib nrab ntawm 2024, ntau 0BB cov khoom yuav nkag mus rau hauv kev ua lag luam, txhaj tshuaj tshiab tseem ceeb rau kev noj qab haus huv thiab kev loj hlob ntawm kev lag luam photovoltaic.
