Nyob rau hauv xyoo tas los no, nrog kev loj hlob thoob ntiaj teb kev thov rau lub zog tauj dua tshiab, hnub ci photovoltaic fais fab kev siv tshuab tau tsim sai heev. Rau cov neeg siv, tsis muaj qhov sib txawv ntawm monocrystalline silicon hlwb thiab polycrystalline silicon hlwb, thiab lawv lub neej ntev thiab kev ruaj ntseg yog ob qho tib si zoo.
** Monocrystalline silicon: kev ua haujlwm siab tab sis tus nqi siab
Monocrystalline silicon hnub ci vaj huam sib luag paub txog lawv cov kev hloov pauv siab, cov khoom siv siab purity, ua tiav cov qauv siv lead ua, thiab tuaj yeem hloov lub hnub ci zog rau hauv hluav taws xob. Txawm li cas los xij, cov txheej txheem tsim khoom ntawm monocrystalline silicon yog qhov nyuaj thiab tus nqi siab, uas kuj tau dhau los ua qhov laj thawj vim li cas ntau lub tuam txhab tsis kam siv monocrystalline silicon li hnub ci vaj huam sib luag hauv ntau qhov ntau.
** Polycrystalline silicon: nqi-zoo tab sis tsawg npaum li cas
Kev hloov dua siab tshiab ntawm polycrystalline silicon hnub ci vaj huam sib luag yog me ntsis qis dua li ntawm monocrystalline silicon, tab sis nws cov nqi tsim tawm kuj tsawg thiab cov nqi ua tau zoo dua. Polycrystalline silicon cov ntaub ntawv yog tsim los ntawm ntau cov muaju me me, cov txheej txheem tsim khoom yog qhov yooj yim, thiab cov khoom loj tuaj yeem ua tiav, yog li lawv nyob hauv kev lag luam loj. Yog li ntawd, ntau lub tuam txhab me me yuav xaiv polycrystalline silicon ua cov khoom siv ntawm cov hnub ci vaj huam sib luag kom txuag tau nqi ntau dua. Tab sis qhov zoo thiab conductivity ntawm qhov no yuav txo..
Yog li ntawd, thaum xaiv photovoltaic modules, peb pom zoo kom xaiv cov siv lead ua silicon photovoltaic uas paub tab raws li qhov tseeb. Peb tsis pom ntau qhov sib txawv hauv kev tsim hluav taws xob ntawm tsev neeg photovoltaic fais fab kev tsim tshuab. Kev siv thaj tsam ntawm ib leeg siv lead ua yuav siab dua, thiab thaj chaw siv tus nqi ntawm ib qho crystals yuav zoo dua. Yog li ntawd, tom qab kev txiav txim siab zoo, peb cov khoom siv hnub ci zog feem ntau siv monocrystalline silicon ua cov khoom tseem ceeb.
Cov no yog Liper hnub ci lub teeb siv ib leeg siv lead ua silicon.
