Cov Xov Xwm Tseeb, Hnub Ci Silicon Wafers Plummeted 20.4%!
Lub Tuam Txhab Kev Lag Luam Silicon tau tshaj tawm tias tus nqi ntawm cov khoom siv silicon siv nyob rau hauv hnub ci vaj huam sib luag poob los ntawm 6.25%. Tus nqi ntawm P-hom M10 monocrystalline silicon wafers tau poob qis. Hauv ib lub lis piam, tus nqi ntawm cov wafers poob los ntawm 20.4%.
Lub lim tiam no, tus nqi nruab nrab ntawm kev hloov pauv ntawm P-hom M10 monocrystalline silicon wafers (182 * 182mm / 150μm) poob rau US $ 0.173 / thooj, ib lub lis piam- nyob rau lub lis piam txo ntawm 20.4%; N-type G10L monocrystalline silicon wafers (182 * 183.75 mm / 130μm / 256mm) Tus nqi nruab nrab ntawm kev lag luam poob mus rau US $ 0.172 / thooj, ib lub lis piam-rau-lub lim tiam txo ntawm 11.4%; tus nqi nruab nrab ntawm N-hom G12R monocrystalline silicon wafer (182 * 210mm / 130μm) yog US $ 0.237 / thooj; tus nqi nruab nrab ntawm kev hloov pauv ntawm P-hom G12 monocrystalline silicon wafer (210 * 210 mm / 150μm), tus nqi nruab nrab ntawm kev lag luam poob mus rau US $ 0.263 / thooj, ib lub lis piam-rau-lub lim tiam ntawm 8.65%. Qhov nruab nrab tus nqi pauv ntawm N-hom G12 monocrystalline silicon wafers (210 * 210 mm / 150μm) yog US $ 0.269 / thooj, ib lub lim tiam-rau-lub lim tiam ntawm 11%.
Lub lim tiam no, kev khiav hauj lwm tus nqi ntawm ob lub tuam txhab thawj theem poob mus rau 60% thiab 80% feem. Kev khiav hauj lwm ntawm cov tuam txhab kev koom ua ke poob mus rau ntawm 60% thiab 80% raws li, thiab cov nqi khiav hauj lwm ntawm lwm cov lag luam poob mus rau ntawm 50% thiab 70% raws li.
Polysilicon cov nqi txuas ntxiv poob rau lub lim tiam no, nrog N-hom nqi kuj zoo ib yam thiab P-hom nqi chaotic. Ntawm lawv, tus nqi pauv ntawm n-hom pas nrig silicon yog 5,678.5-6,232.5 US las / ton, thiab tus nqi nruab nrab yog 5,955.5 US las / ton, ib hlis-rau-hli poob ntawm 5.08% . Tus nqi pauv pauv ntawm p-hom cov ntaub ntawv ntom ntom yog US $ 4, 709-5, 401.5 / tuj, thiab tus nqi nruab nrab yog US $ 5,116 / ton, ib hlis-rau-hli poob ntawm 4.36%. N / p pas nrig silicon tus nqi sib txawv yog US $ 609.4 / ton. Tus nqi pauv ntawm n-hom granular silicon yog US $ 5,124.5-5,401.5/ton, thiab tus nqi nruab nrab yog US $ 5,193.8/ton, ib hlis-rau-hli poob ntawm 6.25%.
Ib qho tseem ceeb ua rau tus nqi poob qis yog qhov khoom siv ntau ntawm cov khoom siv silicon hauv khw. Nyob rau hauv xyoo tas los no, raws li qhov kev thov rau lub hnub ci vaj huam sib luag tau nce, ntau lub tuam txhab tau nce cov khoom siv silicon kom tau raws li qhov xav tau. Txawm li cas los xij, qhov no ua rau muaj qhov xwm txheej ntawm oversupply thiab yog li tus nqi poob.
Lwm qhov tseem ceeb yog cov qauv mus rau lub hnub ci zoo dua, uas yuav tsum tau siv cov khoom siv silicon tsawg dua. Yog li ntawd, kev thov rau cov khoom siv silicon txo qis, ua rau cov nqi poob ntxiv.
Txawm li cas los xij, tsis tas yuav tsum ntshai, vim tias cov nqi poob qis tsis zoo li yuav muaj kev cuam tshuam loj rau kev lag luam hnub ci vaj huam sib luag. Tsis tas li ntawd, cov nqi poob qis tsis zoo ib yam ntawm txhua hom khoom siv silicon. Thaum cov nqi polysilicon tseem poob qis, N-hom silicon cov khoom siv tus nqi tau nyob ruaj khov. Qhov xwm txheej ntawm P-hom silicon cov ntaub ntawv yog qhov nyuaj dua, yog li nws nyuaj rau kwv yees nws cov qauv yav tom ntej.
Ua ke, cov xov xwm no hu rau kev nkag siab ntau ntxiv ntawm cov rog ntawm kev ua si hauv kev lag luam hluav taws xob tauj dua tshiab. Txawm hais tias qhov kev poob qis hauv cov khoom siv silicon tsis ntev los no yuav ua rau muaj kev txhawj xeeb, nws yog ib qho tseem ceeb uas yuav tsum muaj kev cia siab thiab tseem tsom ntsoov rau kev tsim thiab siv cov thev naus laus zis thev naus laus zis tshiab rau lub neej yav tom ntej.
