1. Ib leeg siv lead ua hnub ci vaj huam sib luag
Cov khoom ntawm ib lub pob zeb siv lead ua roj teeb yog tib yam, tab sis nws cov ntawv roj teeb yog ua los ntawm ib qho siv lead ua silicon. (q: monocrystalline silicon yog dab tsi? A: monocrystal ntawm silicon. Nws yog ib qho siv lead ua nrog cov qauv ua tiav lattice. Cov lus qhia sib txawv muaj cov khoom sib txawv, thiab nws yog cov khoom siv semiconducting zoo. Cov purity yuav tsum ncav cuag 99.9999 feem pua, los yog saum toj no. 99.999999%. Hauv tib cheeb tsam, nws tuaj yeem tsim hluav taws xob ntau! Txo cov nqi xauj tsev thiab them nyiaj yug. Thiab nyob rau hauv cov nqe lus ntawm kev ua tau zoo (attenuation, thiab lwm yam), nws yog me ntsis zoo dua polysilicon, tab sis nyob rau hauv cov nqe lus ntawm raug nqi, nws yog siab tshaj polysilicon. Yog li ntawd, tus nqi ntawm ib leeg siv lead ua roj teeb vaj huam sib luag yog siab dua li ntawm polycrystalline silicon roj teeb vaj huam sib luag!
2. Polycrystalline hnub ci vaj huam sib luag
Cov muaj pes tsawg leeg thiab cov qauv ntawm polycrystalline roj teeb vaj huam sib luag yog tib yam li cov siv lead ua ib leeg, tshwj tsis yog tias nws cov ntawv roj teeb yog ua los ntawm polycrystalline silicon. Tom qab kev taw qhia ntawm polycrystalline roj teeb lub rooj tsavxwm, vim nws tus nqi qis, thiab nws cov kev ua tau zoo tsis txawv ntau ntawm cov siv lead ua ib leeg! Lub khw yeej ib txwm nrov heev. Ntxiv mus, vim kev nruam ntej ntawm thev naus laus zis hauv xyoo tas los no, qhov sib txawv ntawm polysilicon roj teeb panels thiab polycrystalline hlwb hauv kev ua tau zoo thiab hloov pauv tus nqi tsis loj heev, uas yuav luag tsis quav ntsej. Tab sis muaj qhov sib txawv loj ntawm tus nqi (tus nqi ntawm ib qho polycrystalline ua ntej 531 tshiab deal tuaj yeem txawv ntawm ob peb xees ib watt). Yog li ntawd, polysilicon yog nrov nyob rau hauv kev ua lag luam. (Txawm li cas los xij, tom qab 531 qhov kev pom zoo tshiab, tus nqi ntawm ib lub roj teeb siv lead ua hluav taws xob tau siab dhau lawm thiab cov nyiaj tau los tsis zoo, yog li tus nqi txo ntawm ib lub roj teeb siv lead ua tau loj heev.)
