Yuav ua li cas M10 Silicon Slice Production yog teb rau 5.36% Kev Loj Hlob?
Kev lag luam hnub ci photovoltaic tau nce siab nyob rau xyoo tas los no, nrog ntau thiab ntau tus neeg tig mus rau lub zog tauj dua tshiab. Hnub ci vaj huam sib luag yog cov khoom tseem ceeb uas siv lub hnub ci los tsim hluav taws xob thiab ua los ntawm silicon wafers. Yog li ntawd, tus nqi ntawm silicon muaj feem cuam tshuam rau tus nqi ntawm lub hnub ci vaj huam sib luag. Hauv lub asthiv tsis ntev los no, cov nqi silicon wafer tau hloov pauv, tshwj xeeb tshaj yog P-hom M10 silicon wafers, uas tau ntsib tus nqi nce me ntsis. Hauv tsab xov xwm no, peb yuav txheeb xyuas cov laj thawj tom qab tus nqi nce thiab tshawb xyuas lub xeev tam sim no ntawm kev ua lag luam silicon.
International Energy Network tau kawm tias thaum Lub Ib Hlis 11, Silicon Industry Branch tshaj tawm cov nqi silicon wafer tshiab. Tus nqi nruab nrab ntawm M10 monocrystalline silicon wafers (182mm / 150μm) tau nce mus rau 2.00 yuan / thooj, ib lub lis piam nce ntawm 5.26; tus nqi nruab nrab ntawm N-hom monocrystalline silicon wafers (182mm / 130μm) poob rau 2.06 yuan / thooj, ib lub lim tiam-rau-lub lim tiam nce A txo ntawm 1.90%; Tus nqi nruab nrab ntawm kev hloov pauv ntawm G12 monocrystalline silicon wafers (210 mm / 150 μm) poob rau 2.89 yuan / thooj, ib lub lis piam-rau-lub lim tiam txo ntawm 3.67%.
Lub Koom Haum Kev Lag Luam Silicon tau hais tias yog vim li cas qhov nce ntawm P-hom M10 silicon wafer tus nqi yog cov khoom lag luam tsis txaus. Tom qab P-hom M10 tau hloov dua siab tshiab rau hauv cov khoom lag luam, muaj cov khoom tsis txaus ib ntus, thiab lub tuam txhab kev koom ua ke txo qis cov khoom lag luam. Tsis tas li ntawd, feem ntau P-type furnaces tau hloov mus rau N-hom, ua rau me ntsis txo P-hom M10 muaj peev xwm ntau lawm, ua rau tus nqi nce me ntsis.
Yuav kom nkag siab ntxiv txog cov laj thawj ntawm tus nqi nce, nws yog ib qho tseem ceeb kom nco ntsoov qhov sib txawv ntawm P-hom silicon thiab N-hom silicon. P-hom silicon muaj cov impurities uas tsim electron qhov, uas tuaj yeem tsim cov cheeb tsam tsis muaj hluav taws xob hu ua "qhov." Ntawm qhov tod tes, N-hom silicon yog doped nrog impurities xws li phosphorus, uas generates tshaj electrons, yog li tsim ib thaj tsam ntawm electron nplua nuj. N-hom silicon yog qhov zoo dua rau cov hnub ci vaj huam sib luag vim tias nws tso cai rau kev txav hluav taws xob ntau dua.
Hais txog kev khiav hauj lwm tus nqi, raws li cov ntaub ntawv los ntawm Silicon Industry Branch, qhov kev khiav hauj lwm tus nqi ntawm silicon wafer tuam txhab uas muag lub lim tiam no yog tib yam li lub lim tiam dhau los, thiab cov nqi khiav hauj lwm ntawm ob lub tuam txhab thawj theem tseem nyob ntawm 65% thiab 95% feem. . Kev khiav hauj lwm ntawm cov tuam txhab kev koom ua ke tau nyob nruab nrab ntawm 75% thiab 80%, thaum cov nqi khiav hauj lwm ntawm lwm cov lag luam tau poob mus rau ntawm 40% thiab 100%.
Nyob rau hauv xyoo tas los no, nrog kev nthuav dav sai ntawm hnub ci photovoltaic kev lag luam, qhov kev thov rau silicon tau nce siab heev. Yog li ntawd, cov tuam txhab lag luam silicon muaj peev xwm ntau lawm, ua rau cov nqi silicon poob qis heev. Txawm li cas los xij, P-hom M10 tus nqi tau pom qhov nce me ntsis vim qhov tsis txaus ntawm P-hom M10 silicon wafers thiab xav tau ntau ntxiv. Tseem, tag nrho cov qauv yog downward raws li tshiab silicon manufacturing technologies yog tsim los rau txo nqi ntau lawm.
Hauv cov ntsiab lus, qhov nce tsis ntev los no ntawm P-hom M10 silicon tus nqi yog vim qhov hloov mus rau N-hom silicon thiab cuam tshuam ntawm kev tsim khoom ua rau cov khoom tsis txaus ib ntus. Kev nthuav dav ntxiv ntawm kev lag luam hnub ci photovoltaic thiab qhov tseem ceeb ntawm kev ruaj ntseg hauv kev tsim hluav taws xob yuav txuas ntxiv mus ntxiv rau kev thov rau silicon, txhawb kev txuas ntxiv tshiab hauv kev ua lag luam.
