Dab tsi yog qhov txawv ntawm monocrystalline thiab polycrystalline hnub ci ci ntsa iab?
Apr 14, 2025| Hnub ci Vaj Huam Sib Luag
Nrog kev nce qib nruam ntawm kev siv hluav taws xob txuas ntxiv thev naus laus zis, hnub ci ci tau siv thoob ntiaj teb. Tam sim no, lub ntsiab hnub ci hnub ci ntsa iab ntawm kev ua lag luam feem ntau muab faib ua ob hom: monocrystalline silicon (monycrystalline silicon (polycrystalline). Lawv txhua tus nyias muaj yam ntxwv sib txawv thiab kev thov zoo, thiab cov kev xaiv tseem ceeb uas cov neeg siv yuav tsum ntsib thaum yuav khoom siv lub hnub ci.
Monocrystalline Silicon Hnub ci Panels yog tsim los ntawm kev txiav cov siab-purity monocrystalline silicon pas nrig rau hauv silicon wafers thiab mam li ua lawv. Cov qauv siv lead ua tas mus li yog tas mus li thiab kev teeb tsa tsis zoo, thiab cov kev ntws tawm ntawm cov hluav taws xob hauv lawv yog me dua. Cov qauv no coj lub zog siab dua hloov dua siab hloov dua siab tshiab, tab sis cov kev tsim qauv tsim qauv kuj yog qhov nyuaj thiab kim.
Nyob rau hauv kev sib piv, polycrystalline silicon hnub ci panels yog ua los ntawm melting silicon cov ntaub ntawv thiab txias rau lawv los ua cov qauv siv lead ua si nrog rau hauv cov hlwb. Vim muaj cov qoob loo ntau, cov khoom poob ntawm cov hluav taws xob hauv cov txheej txheem conduction nce, yog li kev ua tau zoo me me.
Los ntawm lub tswv yim morphology, monocrystalline cov qauv sib dhos ", uas suav nrog qhov sib txawv ntawm ob qho ntawm ob qho hauv ob qho kev ua tau zoo thiab tsos.
Monocrystalline Silicon Hnub ci Panels feem ntau tam sim no cov khaub noom dub dub xim, thiab cov txheej txheem tsis tu ncua, thiab cov ces kaum tau sib npaug me ntsis. Cov tsos no yooj yim thiab niaj hnub, thiab feem ntau siv nyob rau hauv cov chaw nyob siab lossis cov phiaj xwm nrog cov kev xav pom.
Polycrystalline Silicon Hnub Ci Panels pom cov xim xiav lossis xiav-grey, thiab cov txheej txheem nto muaj xim hlau thiab cov qauv tawg. Lub hlwb feem ntau ua tiav cov duab plaub fab, densely tau teem tab sis me ntsis ntxhib, haum rau cov phiaj xwm kev ua haujlwm.
Daim duab photicelectric kev hloov pauv kev ua tau zoo ntawm monocrystalline panels yog feem ntau ntawm 18%, thiab qee qhov kev ua qauv zoo tuaj yeem cuam tshuam ntau dua 24%. Nws cov qauv siv lead ua zoo ua rau lub tshuab hluav taws xob kev pab txhawb, uas yog tsim nyog hloov dua siab rau lub sijhawm nrog kev txwv thiab siab xav tau rau lub zog hluav taws xob.
Kev hloov zuj zus ntawm polycrystalline silicon hnub ci zog yog feem ntau ntawm 15% thiab 18%. Vim muaj ntau tus lej crystal, hluav taws xob kis tau thaiv, thiab ua tau zoo yog qhov tseem ceeb me ntsis. Txawm li cas los xij, hauv cov cheeb tsam uas muaj qhov chaw txaus thiab txaus, nws tseem tuaj yeem muab lub zog ruaj khov ua rau muaj peev xwm.
Hauv qhov kub thiab txias, muaj qhov sib txawv ntawm cov huab cua, yog li xaiv cov vaj huam sib luag hnub ci yog qhov tseem ceeb rau kev ua tau zoo ntev.
Kev sib piv ntawm cov kev pabcuam lub neej thiab kev ruaj khov
Kev sib piv ntawm tus nqi thiab tus nqi
Nyob rau hauv cov nqe lus ntawm kev tsim khoom raug nqi, polycrystalline silicon hnub ci zog yog qhov qis dua li monocrystalline silicon. Nws cov txheej txheem ntau lawm tau yooj yim dua thiab cov khoom siv uas siv tau qhov siab, yog li thawj qhov kev xaiv rau cov neeg siv nrog nyiaj txiag tsawg.
Txawm hais tias tus nqi ntawm tus nqi ntawm monocrystalline Silicon Lub Vaj Huam Sib Luag loj dua, lub neej ntev, tag nrho cov nqi kev ua tau zoo, qhov zoo dua nyob rau qee lub sijhawm.
Hauv kev ua tiav tiag tiag, nws yog ib qho tsim nyog kom muaj kev nkag siab thawj zaug, cov nqi txij nkawm, thiab xaiv lub vaj huam sib luag ntev thiab xaiv lub hnub ci txoj haujlwm muab txoj haujlwm thiab pob nyiaj.
Monocrystalline Silicon Lub Vaj Huam Sib Luag yog qhov haum rau cov xwm txheej, xws li Urban cov khoom siv hluav taws xob, cov khoom siv hluav taws xob ntau lossis cov khoom siv hluav taws xob rau hauv cov chaw deb.
Polycrystalline Silicon Lub Vaj Huam Sib Luag yog qhov tsim nyog rau cov chaw muaj peev xwm loj, xws li cov chaw ua liaj ua teb loj, kev lag luam, nyob deb nroog cov phiaj xwm, thiab lwm yam.
Hauv kev lag luam thiab kev siv cov ntawv thov, tus nqi them tus nqi yuav ua tau raws li lub sijhawm ua peev txheej rov qab; Nyob rau hauv cov teb pej xeem, nws yog ib qho tsim nyog los sib npaug kev ua kom zoo nkauj, peev thiab muaj peev xwm ntau lawm; Thiab hauv cov khoom siv hluav taws xob lossis xwm txheej ceev, lub teeb thiab kev ua haujlwm yog qhov tseem ceeb ntxiv.
Kev sib piv los ntawm kev xav txog kev tiv thaiv ib puag ncig thiab kev ruaj khov
Thaum lub sijhawm cov txheej txheem ntau lawm, Monocrystalline Silicon Hnub ci vaj huam sib luag yuav tsum tau siv siab dua thiab ua kom muaj zog tag nrho, yog li cov kab mob carbon ntau dua yog qhov loj. Cov txheej txheem ntawm polycrystalline silicon solar vaj huam sib luag yog ntau lub zog-ua tau zoo thiab cov khoom poob yog me me.
Ob qho tib si muaj cov kev ua tiav tiav tom qab kev ua haujlwm tom qab silicon yog siab dua, nws tus nqi hloov dua siab tshiab thiab rov siv dua tshiab yuav zoo dua.
Los ntawm qhov kev pom ntawm kev loj hlob ruaj khov, hauv cov phiaj xwm nrog kev tiv thaiv kev tiv thaiv kev tiv thaiv lub neej, tau txais txiaj ntsig kev siv nyiaj, kev khwv nyiaj thiab cov txiaj ntsig kev lag luam.
Los ntawm cov kev sib piv saum toj no, nws tuaj yeem pom tau tias yog koj ua kom lub neej ntev thiab zoo nkauj thiab pom zoo los xaiv monocrystalline Vaj Huam Sib Luag; Yog tias koj them nyiaj ntau rau cov nqi tswj hwm thiab cov chaw tsim teeb meem, koj tuaj yeem muab qhov tseem ceeb rau Polycrystalline Vaj Huam Sib Luag. Hauv kev ua tiav tiag tiag, nws raug nquahu tias cov neeg siv kev tshuaj xyuas txoj kev teeb tsa, cov nqi tsev lag luam, cov nqi kho mob thiab kev tswj xyuas ntev.
