Khoom cim npe

Silicon ib leeg siv lead ua crucibles rau kev lag luam photovoltaic yog cov khoom tseem ceeb uas txhawb kev tsim cov hnub ci cell. Lawv pab ua kom muaj txiaj ntsig zoo ntawm silicon ib leeg siv lead ua kev loj hlob los ntawm kev muab lub pas dej ntshiab thiab ruaj khov, yog li txhim kho kev ua haujlwm thiab zoo ntawm lub hnub ci hlwb. Cov crucibles no tau siv dav hauv kev lag luam photovoltaic, thiab kev tshawb fawb txuas ntxiv thiab kev txhim kho thiab kev tsim kho tshiab pab txhim kho kev ua haujlwm thiab hloov kho ntawm crucibles.

Taw qhia:

1. Kev xaiv cov khoom siv: Txij li kev lag luam photovoltaic muaj cov kev xav tau siab heev rau kev purity ntawm silicon ib leeg muaju, cov crucibles rau rub silicon ib leeg muaju hauv kev lag luam photovoltaic feem ntau yog siv cov khoom siv purity graphite. Cov graphite crucibles no yuav tsum muaj cov purity siab heev thiab tsis muaj impurity cov ntsiab lus los xyuas kom meej tias cov silicon ib leeg muaju muaj ib tug qis impurity concentration, yog li txhim kho cov efficiency ntawm lub hnub ci hlwb.

2. Purity tswj: Lub purity ntawm crucibles rau rub silicon ib leeg muaju nyob rau hauv kev lag luam photovoltaic yuav tsum tau nruj me ntsis tswj thaum lub sij hawm tsim khoom. Cov neeg tsim khoom feem ntau siv ntau txoj hauv kev, xws li kev kho cua sov graphite, tshuaj ntxuav thiab cov coatings tshwj xeeb, los xyuas kom meej qhov purity hauv crucible thiab txo qhov muaj impurities.

3. Molten pool shape control: Lub crucibles rau rub silicon ib leeg muaju nyob rau hauv kev lag luam photovoltaic yuav tsum muaj kev tswj zoo ntawm cov duab ntawm lub pas dej yaj. Qhov no yog los xyuas kom meej tias cov khoom siv silicon tuaj yeem tswj tau lub cev ruaj khov thaum lub sij hawm yaj thiab kev loj hlob, thiaj li tau txais cov khoom zoo silicon ib leeg muaju. Cov qauv tsim tshwj xeeb crucible thiab cov duab hauv qab yuav raug coj los ua kom tau raws li qhov yuav tsum tau ua kom lub pas dej ua kom zoo.

4. Temperature uniformity: Lub crucibles rau rub silicon ib leeg muaju nyob rau hauv kev lag luam photovoltaic yuav tsum muaj thermal conductivity zoo los xyuas kom meej qhov kub thiab txias faib nyob rau hauv lub crucible. Qhov no yuav pab txhim kho cov uniformity ntawm silicon ib leeg muaju thiab txo qhov tsim ntawm impurities thiab tsis xws luag.

5. Corrosion kuj thiab kub tsis kam: Cov silicon ib leeg siv lead ua crucibles siv nyob rau hauv kev lag luam photovoltaic yuav tsum muaj corrosion kuj zoo thiab kub tsis kam tiv thaiv cov tshuaj tiv thaiv uas yuav tshwm sim thaum nyob rau hauv kev sib cuag nrog cov ntaub ntawv silicon ntawm kub. Qhov no pab tswj kev ruaj ntseg thiab kev cia siab ntev ntev ntawm lub crucible.
