Lub Sij Hawm Thaum Ntxov: Cov duab thiab qhov loj me
Kev lag luam hnub ci photovoltaic (PV) taug kev pib nrog monocrystalline thev naus laus zis tau txais los ntawm kev lag luam semiconductor. Qhov no tau cim qhov pib ntawm kev niaj hnubhnub ci evolution. Thaum ntxov monocrystalline hnub ci hlwb tau txawv txav vim lawv tau hlais ncaj qha los ntawm cylindrical silicon ingots.
Qhov sawv ntawm Polycrystalline
Raws li lub hnub ci evolution nkag mus rau nws cov theem tom ntej nrhiav kev lag luam loj, polycrystalline thev naus laus zis tau tshwm sim ua lag luam tseem ceeb. Ua los ntawm cov txheej txheem casting hauv cov pwm square, polycrystalline hlwb yog cov squares zoo meej, tshem tawm cov khoob hauv cov qauv tsim. Txawm hais tias lawv qhov kev hloov pauv tau qis dua li monocrystalline, lawv cov txiaj ntsig zoo heev ua rau lawv lub ntiaj teb tseem ceeb ntawm xyoo 2000 txog 2015.
Niaj hnub no Mega- Wafer Era
Qhov kev ua si tau hloov nrog kev qhia txog pob zeb diamond hlau sawing, uas ua rau poob qis monocrystalline ntau lawm nqi. Txhawm rau txo qis Tus Nqi Them Nqi Zog (LCOE), lub hnub ci evolution tau nrawm rau hauv "kev ua tsov rog loj," nthuav wafers los ntawm 166mm mus rau 182mm thiab 210mm.
Nyob rau tib lub sijhawm, lub zog tso tawm ntawm lub hnub ci vaj huam sib luag tau nce hauv tandem nrog lawv qhov ntev, nce mus txog 600W.
Logistics Bottlenecks
Unchecked lub cev nthuav dav ua rau muaj teeb meem thauj khoom, raws li cov pob khoom yuav tsum haum rau hauv lub qhov rooj qhov siab thiab qhov dav txwv kom ua kom cov ntim ntim ntau tshaj. Niaj hnub no txoj kev lag luam tau mus txog qhov kev pom zoo ntawm qhov ntev, hloov qhov kev tsom xam engineering los ntawm qhov loj me me los ua kom zoo dua cov thawv ntim khoom kom zoo thiab cov khoom siv logistics.
Tom ntej no Frontier
Niaj hnub no, lub hnub ci evolution tau nrawm nrawm rau N- hom thev naus laus zis, uas muaj xoom Lub Teeb-Induced Degradation (LID) thiab qhov kub siab tshaj coefficients, raws li P- hom PERC cell efficiency mus txog lawv txoj kev txwv.
N-Type TOPCon thiab BC Technologies
TOPCon (Tunnel Oxide Passivated Contact):Tam sim no ua cov khoom lag luam tseem ceeb, TOPCon siv cov txheej txheem ultra-thin tunnel oxide kom txo qis kev rov ua dua tshiab, thawb kev lag luam module ua tau zoo dhau los 23%.
BC (Back Contact) Technology:Sawv cev tus hwm ntu ntawm qhov nohnub ci evolution, BC txav tag nrho cov busbars thiab hluav taws xob tiv tauj rau sab nraub qaum. Qhov no tawm hauv pem hauv ntej kom tsis muaj kev cuam tshuam, ua kom pom lub hnub ci siab tshaj plaws thiab ua kom muaj txiaj ntsig zoo, tag nrho - dub zoo nkauj zoo meej rau siab - kawg cov tsev nyob saum ru tsev.
Hauv kev xaus, nkag siab qhovhnub ci evolutionpab cov neeg yuav khoom paub tias kev yuav khoom PV niaj hnub no tsis yog hais txog kev yuav lub vaj huam sib luag loj; nws yog qhov sib npaug ntawm N- hom cell efficiency thiab optimized shipping qhov ntev kom ua tiav tus nqi qis tshaj ib watt.
