1. Qhov sib txawv ntawm cov khoom siv phaj siv lead ua ib leeg thiab cov khoom siv phaj polycrystalline

Polycrystalline silicon thiab single crystal silicon yog ob yam khoom sib txawv. Polysilicon yog ib lo lus tshuaj lom neeg uas feem ntau hu ua iav, thiab cov khoom siv polysilicon uas muaj kev ntshiab siab yog iav uas muaj kev ntshiab siab. Monocrystalline silicon yog cov khoom siv raw rau kev ua cov hlwb photovoltaic hnub ci, thiab nws kuj yog cov khoom siv rau kev ua cov chips semiconductor. Vim yog qhov tsis txaus ntawm cov khoom siv raw rau kev tsim cov monocrystalline silicon thiab cov txheej txheem tsim khoom nyuaj, cov zis tsawg thiab tus nqi kim.
Qhov txawv ntawm cov siv lead ua ib leeg silicon thiab polycrystalline silicon yog nyob rau hauv lawv cov qauv atomic. Cov siv lead ua ib leeg raug txiav txim siab thiab cov polycrystalline tsis sib haum xeeb. Qhov no feem ntau yog txiav txim siab los ntawm lawv cov txheej txheem ua. Polycrystalline thiab polycrystalline yog tsim los ntawm txoj kev nchuav, uas yog ncaj qha nchuav cov khoom siv silicon rau hauv lub lauj kaub kom yaj thiab zoo. Cov siv lead ua ib leeg siv txoj kev Siemens los txhim kho Czochralski, thiab cov txheej txheem Czochralski yog ib qho txheej txheem ntawm kev rov kho dua cov qauv atomic. Rau peb lub qhov muag liab qab, qhov chaw ntawm monocrystalline silicon zoo ib yam. Qhov chaw ntawm polysilicon zoo li muaj ntau lub iav tawg sab hauv, ci ntsa iab.
Vaj huam sib luag hnub ci monocrystalline: tsis muaj qauv, xiav tsaus, yuav luag dub tom qab ntim khoom.
Vaj huam sib luag hnub ci polycrystalline: Muaj cov qauv, muaj cov xim polycrystalline thiab cov xim tsis tshua muaj xim, xiav daj.
Cov vaj huam sib luag hnub ci tsis muaj zog: feem ntau ntawm lawv yog iav, xim av thiab xim av.
 
2. Cov yam ntxwv ntawm cov khoom siv phaj siv lead ua ib leeg

Cov vaj huam sib luag hnub ci monocrystalline silicon yog ib hom roj teeb hnub ci uas tam sim no tab tom tsim kho sai. Nws cov khoom sib xyaw thiab cov txheej txheem tsim khoom tau ua tiav lawm. Cov khoom lag luam tau siv dav hauv qhov chaw thiab hauv av. Hom roj teeb hnub ci no siv cov pas nrig silicon uas muaj qhov huv si siab ua cov khoom siv raw, thiab qhov yuav tsum tau ua kom huv yog 99.999%. Kev ua haujlwm hloov pauv photoelectric ntawm cov roj teeb hnub ci monocrystalline silicon yog li 15%, thiab qhov siab tshaj plaws ncav cuag 24%. Qhov no yog qhov ua haujlwm hloov pauv photoelectric siab tshaj plaws ntawm cov roj teeb hnub ci tam sim no. Txawm li cas los xij, tus nqi tsim khoom loj heev uas nws tsis tuaj yeem siv dav thiab dav. Txij li thaum monocrystalline silicon feem ntau yog encapsulated nrog iav tempered thiab cov tshuaj tiv thaiv dej, nws yog rugged thiab ruaj khov, nrog lub neej ua haujlwm txog li 15 xyoo thiab txog li 25 xyoo.
 
3. Cov yam ntxwv ntawm cov ntaub ntawv polycrystalline board

Cov txheej txheem tsim khoom ntawm polycrystalline silicon solar panels zoo ib yam li polycrystalline silicon solar panels. Txawm li cas los xij, qhov ua tau zoo ntawm kev hloov pauv photoelectric ntawm polycrystalline silicon solar cells qis dua. Nws qhov ua tau zoo ntawm kev hloov pauv photoelectric yog li 12%. Hais txog tus nqi tsim khoom, nws qis dua li ntawm monocrystalline silicon solar cells. Cov khoom siv yooj yim tsim, txuag hluav taws xob, thiab tag nrho cov nqi tsim khoom qis, yog li nws tau tsim kho ntau heev. Tsis tas li ntawd, lub neej ua haujlwm ntawm polycrystalline silicon solar cells luv dua li ntawm monocrystalline silicon solar cells. Hais txog kev ua tau zoo ntawm tus nqi, monocrystalline silicon solar cells zoo dua me ntsis.
