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

Polycrystalline silicon thiab ib leeg siv lead ua silicon yog ob yam khoom sib txawv.Polysilicon yog ib lo lus tshuaj feem ntau hu ua iav, thiab cov khoom siv high-purity polysilicon yog cov iav purity siab.Monocrystalline silicon yog cov khoom siv raw rau kev ua lub hnub ci photovoltaic hlwb, thiab nws kuj yog cov khoom siv los ua cov khoom siv semiconductor.Vim tias tsis tshua muaj cov khoom siv raw rau kev tsim cov monocrystalline silicon thiab cov txheej txheem tsim khoom nyuaj, cov khoom tsim tawm yog tsawg thiab tus nqi kim.
Qhov sib txawv ntawm ib leeg siv lead ua silicon thiab polycrystalline silicon nyob rau hauv lawv cov qauv atomic.Ib leeg siv lead ua tau txiav txim thiab polycrystals tsis zoo.Qhov no feem ntau yog txiav txim siab los ntawm lawv cov txheej txheem thev naus laus zis.Polycrystalline thiab polycrystalline yog tsim los ntawm cov txheej txheem pouring, uas yog ncaj qha ncuav cov khoom silicon rau hauv lub lauj kaub kom yaj thiab zoo li.Cov siv lead ua ib leeg txais txoj kev Siemens los txhim kho Czochralski, thiab cov txheej txheem Czochralski yog txheej txheem ntawm kev hloov kho cov qauv atomic.Rau peb qhov muag liab qab, qhov saum npoo ntawm monocrystalline silicon zoo li qub.Qhov saum npoo ntawm polysilicon zoo li yog tias muaj ntau cov iav tawg hauv, ci ntsa iab.
Monocrystalline hnub ci vaj huam sib luag: tsis muaj qauv, tsaus xiav, ze li dub tom qab ntim.
Polycrystalline hnub ci vaj huam sib luag: Muaj cov qauv, muaj polycrystalline yeeb yuj thiab polycrystalline tsis tshua muaj yeeb yuj, lub teeb xiav.
Amorphous solar panels: feem ntau ntawm lawv yog iav, xim av thiab xim av.
 
2. Cov yam ntxwv ntawm ib leeg siv lead ua phaj khoom

Monocrystalline silicon hnub ci vaj huam sib luag yog ib hom hnub ci cell uas tam sim no tau tsim sai.Nws muaj pes tsawg leeg thiab cov txheej txheem ntau lawm tau ua tiav.Cov khoom tau siv dav hauv qhov chaw thiab hauv av.Lub hnub ci cell no siv high-purity ib leeg siv lead ua silicon pas nrig ua raw khoom, thiab purity yuav tsum yog 99.999%.Lub photoelectric conversion efficiency ntawm monocrystalline silicon hnub ci hlwb yog li ntawm 15%, thiab siab mus txog 24%.Qhov no yog lub siab tshaj plaws photoelectric conversion efficiency ntawm tam sim no hom hnub ci hlwb.Txawm li cas los xij, tus nqi tsim khoom yog qhov zoo heev uas nws tsis tuaj yeem siv rau hauv qhov loj thiab dav.Txij li thaum monocrystalline silicon feem ntau encapsulated nrog tempered iav thiab waterproof resin, nws yog rugged thiab ruaj, nrog ib tug kev pab cuam lub neej txog li 15 xyoo thiab mus txog 25 xyoo.
 
3. Cov yam ntxwv ntawm cov khoom siv polycrystalline board

Kev tsim cov txheej txheem ntawm polycrystalline silicon solar panels zoo ib yam li polycrystalline silicon solar panels.Txawm li cas los xij, lub photoelectric hloov dua siab tshiab ntawm polycrystalline silicon hnub ci hlwb yog qis dua.Nws photoelectric conversion efficiency yog hais txog 12%.Hais txog tus nqi tsim khoom, nws yog qis dua li ntawm monocrystalline silicon solar cells.Cov khoom siv yooj yim rau kev tsim khoom, txuag hluav taws xob siv, thiab tag nrho cov nqi tsim khoom tsawg, yog li nws tau tsim ntau heev.Tsis tas li ntawd, lub neej kev pab cuam ntawm polycrystalline silicon hnub ci hlwb yog luv dua li ntawm monocrystalline silicon hnub ci hlwb.Nyob rau hauv cov nqe lus ntawm cov nqi kev ua tau zoo, monocrystalline silicon solar cells yog me ntsis zoo dua.
