Polysilicon yog dab tsi?
Polysilicon, tseem hu ua polycrystalline silicon, yog siab - daim ntawv purity ntawm silicon ua los ntawm ntau cov qauv siv lead ua me me. Nws yog dav siv los ua cov khoom siv raw hauv ob qho tib si photovoltaic thiab semiconductor industries.
Tsis zoo li metallurgical-qib silicon, polysilicon tau dhau los ua cov txheej txheem purification nyuaj kom tshem tawm cov impurities thiab ua tiav qib ntawm purity xav tau rau siab - daim ntawv thov kev ua tau zoo.
Hauv cov ntsiab lus siv tau, polysilicon tsis yog cov khoom tiav -nws yog ib qhokhoom noj khoom haussiv los tsim cov silicon wafers, uas tau ua tiav rau hauv lub hnub ci hlwb lossis cov khoom siv hluav taws xob.
Hnub Ci - Qib Polysilicon yog dab tsi?
Hnub ci- qib polysiliconyog hais txog siab -purity silicon tshwj xeeb uas tsim los siv rau hauv photovoltaic (PV) daim ntawv thov.
Nws feem ntau muaj qib purity xws li los ntawm99.999% (5N) rau 99.9999% (6N), uas yog txaus rau lub hnub ci zog hloov dua siab tshiab.
Piv nrog rau semiconductor- qib silicon, hnub ci- qib polysilicon muaj cov kev cai purity qis me ntsis, tso cai rau tus nqi ntau dua - ua haujlwm loj - nplai ntau lawm.
Yuav Ua Li Cas Polysilicon Ua Tau
Kev tsim cov polysilicon pib los ntawm metallurgical- qib silicon thiab koom nrog cov txheej txheem tshuaj purification.
Txoj kev siv dav tshaj plaws yog qhovSiemens txheej txheem, qhov twg silicon tebchaw yog refined thiab tso rau ntawm qhov kub thiab txias los ua high -purity silicon rods.
Lwm txoj kev tshwm sim yog qhovFluidized txaj Reactor (FBR)txheej txheem, uas muaj qis zog noj thiab txhim kho efficiency.
Los ntawm kev pom kev lag luam, tus nqi tsim khoom thiab kev siv hluav taws xob yog qhov tseem ceeb cuam tshuam rau polysilicon mov thiab nqi.
Vim li cas Hnub Ci Kev Lag Luam nyob ntawm Polysilicon
Polysilicon yog cov khoom siv tseem ceeb rau kev tsim cov hnub ci hnub ci.
Tom qab purification, nws yog:
Melted thiab tsim rau hauv silicon ingots
Txiav rau hauv wafers
Ua rau hauv cov cell photovoltaic
Ntau tshaj 90% ntawm cov hnub ci vaj huam sib luag tso siab rau silicon- cov ntaub ntawv raws li, ua polysilicon yog ib qho tseem ceeb hauv kev hloov pauv hluav taws xob thoob ntiaj teb.
Solar Qib vs Semiconductor Qib Polysilicon
Txawm hais tias ob qho tib si yog siab -cov ntaub ntawv silicon purity, lawv cov kev siv thiab cov kev xav tau txawv heev.
| Hom | Purity | Daim ntawv thov |
|---|---|---|
| Hnub Ci Qib | 5N–6N | Hnub ci vaj huam sib luag |
| Qib Semiconductor | 7N–9N+ | Chips, electronics |
Semiconductor- qib polysiliconyuav tsum tau tsis tshua muaj impurity theem vim hais tias txawm cov kab lus yuav cuam tshuam rau hluav taws xob kev ua tau zoo.
Cov Khoom Tseem Ceeb ntawm Hnub Ci- Qib Polysilicon
Hnub ci- qib polysilicon muaj nuj nqis rau ntau yam tseem ceeb:
High purity rau kev hloov hluav taws xob zoo
Zoo hluav taws xob conductivity
Stable crystalline qauv
Resistance rau corrosion thiab degradation
Cov khoom no ncaj qha cuam tshuam rau kev ua haujlwm thiab lub neej ntev ntawm cov hnub ci vaj huam sib luag.
