Refining ntawm monocrystalline silicon:

Refining ntawm monocrystalline silicon:

Elemental silicon uas tsis muaj purity yuav ua tau los ntawm kev txo silicon dioxide nrog hlau magnesium los yog txhuas, tab sis qhov no yog amorphous silicon. Crystalline silicon yog tsim los ntawm kev txo cov silicon dioxide nrog cov pa roj carbon nyob rau hauv ib qho hluav taws xob arc rauv, uas tuaj yeem siv los tsim cov ntawv silicon steel. Cov txheej txheem rau kev npaj ultra-ntshiab silicon siv los ua ib lub semiconductor yog thawj zaug siv cov khoom sib xyaw uas tsis muaj purity silicon, hydrogen chloride thiab chlorine los npaj trichlorosilane, thiab tom qab ntawd ntxuav nws los ntawm distillation. Tom qab ntawd cov trichlorosilane raug txo nrog cov ntshiab hydrogen hauv qhov txo qhov cub, thiab cov silicon tso rau ntawm cov tub ntxhais zoo ua los ntawm ultrapure silicon. Lub ultrapure silicon tau nyob rau hauv txoj kev no yog hu ua polysilicon, thiab nws tau muab tso rau hauv ib lub qhov cub siv lead ua. Nws tuaj yeem kos rau hauv ib qho siv lead ua silicon, uas tuaj yeem siv los ua cov khoom siv semiconductor. Nws muaj ntau qhov chaw thiab tus nqi qis. Feem ntau ntawm cov khoom siv semiconductor siv silicon.

Monocrystalline silicon yog siv dav hauv kev lag luam hnub ci

Monocrystalline silicon yog dav siv nyob rau hauv lub hnub ci hlwb. High-purity ib leeg siv lead ua silicon yog ib qho tseem ceeb ntawm cov khoom siv semiconductor. Nrog kev txhim kho sai ntawm photovoltaic thev naus laus zis thiab micro-semiconductor inverter thev naus laus zis, lub hnub ci hlwb tsim los ntawm kev siv silicon ib leeg muaju tuaj yeem hloov lub hnub ci ncaj qha rau hauv lub teeb lub zog. Qhov pib ntawm lub zog ntsuab kiv puag ncig. Cov yam ntxwv ntawm monocrystalline silicon solar cells: 1. High photoelectric conversion efficiency thiab muaj kev ntseeg siab; 2. Advanced diffusion technology los xyuas kom meej lub uniformity ntawm conversion efficiency nyob txhua qhov chaw ntawm lub nti; 3. Siv cov txheej txheem PECVD zaj duab xis ua tshuab rau saum npoo ntawm tes Plated nrog tsaus xiav silicon nitride los tiv thaiv zaj duab xis, cov xim zoo ib yam thiab zoo nkauj; 4. Siv cov khoom siv hlau zoo tshaj plaws los ua rau sab nraub qaum thiab cov khoom siv hluav taws xob kom ntseeg tau zoo conductivity.

Monocrystalline silicon yog cov khoom zoo raw khoom hauv qhov chaw

Nyob rau hauv qhov chaw, nws yog ib qho tseem ceeb raw khoom rau chaw shuttles, spacecraft, thiab dag satellites. Hauv kev taug kev ntawm kev kov yeej lub ntiaj teb, tib neeg tau ua txhua kauj ruam ntawm kev nce qib, muaj ib daim duab ntawm monocrystalline silicon. Feem ntau ntawm cov khoom siv aerospace yog raws li monocrystalline silicon. Yog tsis muaj monocrystalline silicon, satellites yuav tsis muaj zog, tsis muaj monocrystalline silicon, chaw shuttles thiab astronauts yuav tsis nyob rau hauv kev sib cuag nrog lub ntiaj teb. Monocrystalline silicon, raws li lub hauv paus pob zeb ntawm tib neeg kev kawm txuj ci, tau ua ib qho kev pab tsis tau rau noob neej lub conquest ntawm qhov chaw.
