Monocrystalline txawv ntawm Polycrystalline Solar Panels li cas?
1. Silicon ua:
Polycrystalline: Hauv kev tsim khoom, silicon crystals yog melted thiab poured rau hauv ib lub square pwm, txias, thiab ua ib tug ingot ua los ntawm ntau muaju. Tom qab ntawd lub ingot yog txiav mus rau hauv wafers. Tsawg zog yog siv los tsim polycrystalline solar cells dua li monocrystalline, muaj qhov nyuaj tsawg, thiab cov nqi tsim khoom pheej yig dua.
Monocrystalline: Silicon yog rhuab mus rau qhov kub thiab txias thiab yog tom qab kos rau hauv ib lub pob zeb siv lead ua siv cov txheej txheem rub. Qhov no ingot yog txiav mus rau hauv wafers. Cov atoms silicon tau teem ib yam hauv cov siv lead ua uas txhais tau hais tias muaj qhov tsis xws luag, uas ua rau muaj hluav taws xob qis dua. Qhov no ua rau kev txhim kho hluav taws xob, tab sis qhov no los nrog cov nqi tsim khoom ntau dua.
2. Module tsos thiab xim:
Polycrystalline: Txawm hais tias cov kev taw qhia ntawm cov nplej muaj ntau qhov sib txawv, feem ntau ntawm cov sij hawm cov chaw no tshwm xiav uas muaj kev cuam tshuam uas muaj xim xim.
Monocrystalline: Cov no feem ntau yuav tshwm sim dub lossis tsaus grey nrog cov qauv siv lead ua rau ntawm qhov muag liab qab, thiab yuav zoo li zoo dua nrog cov qauv niaj hnub thiab qhov tshwm sim ntawm cov vaj tsev architectural.
3. Kev Hloov Ua Haujlwm Zoo:
Polycrystalline: Kev ua tau zoo zoo li ntawm 13--16% nrog kev ua haujlwm tsawg. Qhov zoo tshaj plaws rau cov haujlwm uas tab tom nrhiav kom txwv cov nqi pib / nyiaj ntsuab.
Monocrystalline: Kev ua tau zoo nyob ntawm 18--22%. Cov tiam tom ntej ntawm lub zog muaj kev koom ua ke PERC, TOPCon, HJT, thiab IBC technologies thiab hauv qee qhov kev ua tau zoo tam sim no tshaj 23%. Lawv tsim lub zog ntau dua rau tib thaj chaw saum npoo thiab yog li haum rau cov ru tsev uas tsis muaj qhov chaw loj. Cov qauv thaum ntxov ntawm monocrystalline modules muaj qee qhov teeb meem me me txog kev ruaj ntseg thiab kev ua haujlwm thaum raug kub siab dua thiab qis dua lub teeb pom kev zoo dua li cov qauv polycrystalline tab sis cov qauv tiam tam sim no hauv cov qauv tsim uas siv ib nrab txiav, 1/3-txiav (Twisun Pro), thiab shingle thev naus laus zis tau ua kom muaj kev nce qib tseem ceeb ntawm kev ruaj ntseg thiab kev ua haujlwm.
4. Nqe:
Monocrystalline: Cov nqi tau pib muag ntawm tus nqi them rau polycrystalline, tab sis tau pib poob qis vim cov nqi module tau txo qis vim yog ob qho tib si nce hauv kev tsim khoom thiab kev nce qib rau kev tsim khoom. Yog li txawm hais tias qhov zoo, qhov ua tau zoo dua feem ntau yog - thiab tseem muab qee qhov kev txuag nyiaj BOS nrog rau cov khoom siv hluav taws xob ntau dua - muab kev sib tw LCOE tag nrho.
Polycrystalline: Tsis muaj ntau rau cov txheej txheem, thiab lawv siv lub zog me me hauv kev tsim khoom, tab sis cov txiaj ntsig zoo tsis yog qhov tseem ceeb ntxiv vim qhov kev thov tsis muaj zog thiab lawv cov kev lag luam ntawm cov nplai tsis tshua muaj suab nrov, thiab lawv kuj xav tau ntau qhov chaw, ntau qhov kev sib txuas, txuas txuas ntxiv mus rau qhov kawg ntawm tib lub peev xwm, uas tsis muaj zog qhib kev lag luam zoo rau cov tswv haujlwm.
Muaj qee tus nqi sib txawv ntawm cov kev xaiv monocrystalline: PERC tau txais koj qhov kev xaiv pheej yig tshaj plaws tab sis tab tom ncav nws qhov kev txwv ntawm kev ua tau zoo (~ 22%); TOPCon muaj tus nqi them me ntsis rau PERC tab sis muaj txiaj ntsig zoo dua thiab txuas ntxiv muab kev ua haujlwm zoo dua vim tias qhov txo qis qis dua - muaj tus nqi zoo / txiaj ntsig profile; HJT thiab IBC yog tus nqi ntau dua thiab yog rau kev ua haujlwm siab lossis kev ua haujlwm siab tshaj plaws.

Kev Kawm Txuj Ci
Kev kawm txuj ci tau ua ib qho tseem ceeb. Kev tsim kho tshiab hauv cov tshuab siv lead ua kev loj hlob, xws li Czochralski (CZ) siv lead ua kev loj hlob, tau txhim kho qhov zoo ntawm monocrystalline silicon los ntawm kev txo qis impurity txwv thiab hluav taws xob tsis xws luag. Advanced automated control systems tam sim no tseem tuaj yeem tswj qhov kub thiab txias gradients khaws cia rau txhua lub siv lead ua, pab tsim muaj peev xwm thiab txo cov nqi.
Qhov zoo ntawm monocrystalline silicon txhais tau hais tias nws yog qhov tsim nyog rau kev ua haujlwm thev naus laus zis uas tau tshwm sim. Kev ua lag luam tau hloov pauv, raws li tau hais los ntawm kev ua lag luam thiab cov lus tshaj tawm muaj nyob rau ntawm ntau -crystalline silicon, uas yav tas los muaj ntau tshaj plaws crystalline silicon thev naus laus zis, tab sis tom qab ntawd tsis tuaj yeem sib tw nrog cov txiaj ntsig thiab cov nqi ntawm cov tshuab monocrystalline.
Kev txiav txim siab yav tom ntej
Kev pom zoo rau kev lag luam hnub ci yog khi rau kev tswj hwm ntawm monocrystalline silicon. Cov pov thawj ua tau zoo ntawm monocrystalline silicon nrog kev txhim kho thev naus laus zis thiab tsoomfwv cov cai muaj zog yuav txhawb nqa monocrystalline silicon rau xyoo tom ntej raws li cov thev naus laus zis tseem ceeb. Tsuav qhov kev ua tau zoo tseem nce ntxiv thiab cov nqi tsim khoom txuas ntxiv txo qis, kev siv cov monocrystalline silicon tseem yuav yog qhov tseem ceeb hauv kev hloov pauv thoob ntiaj teb mus rau lub zog muaj zog yav tom ntej.
