Kev ntxuav thiab rov qab siv tshuab ntawm argon roj hauv photovoltaic ib lub cub tawg siv lead ua
Cov pa roj argon muaj cov ntsiab lus qis heev hauv huab cua (tsuas yog 0.93%) thiab feem ntau yog sib cais thiab rho tawm ua cov khoom lag luam los ntawm cov txheej txheem tsim cov pa oxygen sib cais. Tus nqi tsim khoom ntawm cov pa roj argon purity siab yog qhov siab heev. Cov pa roj argon purity siab (purity> 99.999%) yog cov pa roj huv thiab tiv thaiv tseem ceeb hauv cov txheej txheem npaj ntawm cov silicon siv lead ua ke thiab polycrystalline silicon. Cov thev naus laus zis ntxuav thiab rov qab los ntawm cov pa roj argon txawv teb chaws kim heev, thiab lub peev xwm tsim khoom tsawg. Yog li ntawd, kev tsim cov cuab yeej siv argon purification thiab rov qab siv uas pheej yig thiab muaj peev xwm siab nrog cov cai tswjfwm kev txawj ntse ywj pheej tau dhau los ua ib txoj haujlwm ceev uas yuav tsum tau daws.
Cov pab pawg neeg nyuam qhuav tsim cov thev naus laus zis catalytic uas ua haujlwm tau zoo thiab ruaj khov, thiab tau tsim cov txheej txheem thev naus laus zis thiab cov khoom siv tiav raws li kev thov kev lag luam rau argon purification thiab rov qab los hauv Large-scale photovoltaic ib leeg siv lead ua cub tawg. Lub tshuab prototype nyuam qhuav tau tsav ua tiav ntawm Baotou Meike Silicon Energy Co., Ltd. Nyob rau hauv cov xwm txheej tsis kub, ntau yam impurities hauv argon tus Tsov tus tw roj ntawm ib leeg siv lead ua cub tawg raug tshem tawm zoo, thiab qhov concentration ntawm ntau yam impurities hauv cov roj argon purified yog tsawg dua 0.5ppm, zoo dua li PV6-1110 argon roj kev lag luam tus qauv (impurity concentration lt; 10ppm) hauv cov txheej txheem ntau lawm ntawm photovoltaic crystalline silicon. Cov thev naus laus zis no tuaj yeem ua tau raws li qhov yuav tsum tau ua kom huv si argon roj ntawm tsawg kawg 4 txog 6 ib leeg siv lead ua cub tawg nyob rau hauv cov xwm txheej ua haujlwm tiag tiag, txo qis kev siv cov roj argon purity siab hauv cov txheej txheem tsim khoom ntawm crystalline silicon thiab pab cov tuam txhab photovoltaic kov yeej qhov cuam tshuam ntawm kev hloov pauv ntawm cov roj argon. Kev pib ua tiav ntawm lub Hoobkas sim ua rau lub hauv paus kev tsim khoom loj tom ntej.
Kev txhim kho cov thev naus laus zis no zoo yuav txo qis tus nqi ntawm kev tsim hluav taws xob hnub ci, coj cov txiaj ntsig kev lag luam loj rau kev lag luam photovoltaic hnub ci, thiab txhim kho qhov kev sib tw tseem ceeb ntawm Tuam Tshoj kev lag luam photovoltaic.
