Nyob rau hauv lub hnub ci zog sector, silicon wafers los yog solar cells yog cov khoom tseem ceeb. Tus nqi ntawm cov khoom tseem ceeb no ua lub luag haujlwm tseem ceeb hauv kev lag luam hnub ci zog. Lub lim tiam no yog qhov tseem ceeb rau kev lag luam hnub ci hluav taws xob vim tias tus nqi ntawm silicon wafers zoo li tau qis dua, qhia tias tus nqi tau ruaj khov.
Lub koom haum Silicon Kev Lag Luam tau tshaj tawm cov nqi tshiab ntawm monocrystalline silicon wafers lub lim tiam no, ntawm cov uas nruab nrab cov nqi pauv ntawm N-hom G10L monocrystalline silicon wafers (182 * 183.75mm / 130μm / 256mm ) tseem nyob ntawm US$0.159/thooj, uas yog ib lub lis piam-rau-lub lim tiam; tus nqi nruab nrab ntawm N-hom G12R monocrystalline silicon wafers (182 * 210mm / 130μm) tseem nyob ntawm US $ 0.207 / thooj, uas yog tiaj tus nyob rau lub lim tiam; tus nqi nruab nrab ntawm N-hom G12 monocrystalline silicon wafers (210 * 210 mm / 150μm) tseem nyob ntawm US $ 0.263 / thooj, uas yog tiaj tus nyob rau lub lim tiam.
Monocrystalline silicon wafers yog cov khoom siv yooj yim siv hauv cov hnub ci vaj huam sib luag. Lub lim tiam no, cov nqi silicon tau ntaus cov ntaub ntawv qis. Txawm li cas los xij, cov xov xwm zoo yog tias kev lag luam tau zoo dua qub; qhov no yuav qhia tau tias cov nqi silicon yog stabilizing.
Nyob rau lub Tsib Hlis 29, Silicon Industry Ceg tau tshaj tawm tus nqi tshiab ntawm cov khoom siv polysilicon lub lim tiam no. Polysilicon tus nqi poob me ntsis lub lim tiam no. Ntawm lawv, tus nqi pauv ntawm n-hom pas nrig silicon yog 5, 528-5,943 US las / ton, thiab tus nqi nruab nrab ntawm kev sib pauv yog 5,776.8 US las / ton, txo qis ntawm 2.79% lub hli-rau-hli . Tus nqi pauv pauv ntawm p-hom khoom ntom ntom yog 4,698. Tus nqi pauv ntawm n-hom granular silicon yog 5,113.4-5,389.8 US las / ton, thiab tus nqi nruab nrab yog 5,182.5 yuan / ton, uas yog lub hli tiaj tus.
Lub lim tiam no, kev lag luam ntim ntawm polysilicon tsawg heev, thiab feem ntau ntawm lawv yog ib qho kev lag luam. Ntawm lawv, peb lub tuam txhab muaj kev hloov pauv tshiab rau n-hom pas nrig silicon, thiab tsis muaj kev lag luam raug suav rau p-type pas nrig silicon. Qee lub tuam txhab tau tshaj tawm tias tsuas yog cov khoom siv coral muaj qee qhov kev muag khoom sab nraud, tab sis tag nrho lawv tseem tab tom ua raws li kev txiav txim yav dhau los.
Cov tuam txhab roj teeb tshaj lij tau pib yuav cov khoom siv raw hauv ntau, xaus lawv txoj kev tos-thiab-saib cov tswv yim thiab npaj rau kev rov qab los ntawm kev lag luam hnub ci. Feem ntau cov tuam txhab pom qhov kev txav no yog lub sijhawm los ntxiv cov khoom muag silicon wafer vim tias cov nqi qis.
Kev ruaj khov ntawm cov nqi silicon tsis yog qhov xav tsis thoob, vim tias cov nqi silicon wafer tau poob rau keeb kwm qis vim muaj kev xav tau ntau ntxiv thiab cov khoom lag luam cuam tshuam. Txawm li cas los xij, kev ua lag luam zoo li tau pib teb zoo, qhia tias kev lag luam ruaj khov. Kev txhim kho tseem ceeb hauv kev ua lag luam thiab qhov kev thov nce ntxiv los ntawm cov tuam txhab roj teeb tuaj yeem yog cov cim qhia ntxov ntawm kev lag luam hloov pauv.
