Lub cib fim kom nce kev rho tawm yog txwv
Kev hloov pauv thev naus laus zis hauv kev tsim cov hnub ci vaj huam sib luag tau txhawb nqa kev thov rau cov nyiaj, ib qho tshwm sim uas ua rau muaj kev tsis txaus ntawm cov khoom siv hlau zoo, thaum muaj sijhawm tsawg ntawm lub qab ntug kom ruaj ntseg ntxiv mining, sau Bloomberg.
Nyiaj, nyob rau hauv daim ntawv ntawm paste, yog siv rau ib tug conductive txheej nyob rau hauv pem hauv ntej thiab sab nraum qab ntawm silicon hnub ci hlwb. Tab sis lub sector twb tau pib tsim ntau yam sib txawv ntawm cov hlwb uas siv hlau ntau dua, thiab qhov no yuav ntxiv rau cov khoom siv uas twb muaj lawm.
Hnub ci zog tseem tsim ib feem me me ntawm tag nrho cov kev thov rau nyiaj, tab sis nws loj hlob tuaj. Raws li tsab ntawv ceeb toom los ntawm Lub Tsev Haujlwm Nyiaj Txiag, nws yuav ua rau 14% ntawm kev siv rau xyoo no, nce li ntawm 5% xyoo 2014. Feem ntau ntawm qhov kev loj hlob yog los ntawm Tuam Tshoj, uas xav tias yuav nruab ntau lub hnub ci vaj huam sib luag rau xyoo no. , tshaj US.
Raws li BloombergNEF, tus qauv passivated emitter thiab rov qab hu xov tooj yuav zoo li yuav dhau los ntawm ob mus rau peb xyoos tom ntej los ntawm qhov oxide passivated hu thiab heterojunction qauv. Thaum nyob rau hauv thawj rooj plaub hlwb xav tau txog 10 milligrams ntawm cov nyiaj ib watt, qhov oxide hlwb xav tau 13 milligrams thiab heterojunction hlwb 22 milligrams.
Nyob rau tib lub sijhawm, cov khoom siv tau pib saib tsawg. Nws tau tiaj tus xyoo tas los, txawm hais tias qhov kev thov tau nce los ntawm ze li ib feem tsib, cov ntaub ntawv ntawm Lub Tsev Haujlwm Nyiaj Txiag tau qhia. Xyoo no, kev tsim khoom tau kwv yees nce los ntawm 2%, thaum kev lag luam kev lag luam xav tias yuav loj hlob los ntawm 4%.
Qhov teeb meem rau cov neeg yuav nyiaj yog tias nws tsis yog qhov yooj yim los nce cov khoom, muab pes tsawg mines muaj feem ntau rau cov nyiaj ntau lawm. Txog 80% ntawm cov khoom siv hlau yog los ntawm txhuas, zinc, tooj liab thiab kub mining tej yaam num, qhov twg nyiaj yog ib tug byproduct.
Thiab nyob rau hauv ib puag ncig uas cov tuam txhab mining tsis kam cog lus rau cov haujlwm tshiab loj, cov nyiaj qis dua piv rau lwm cov hlau muaj nuj nqis thiab kev lag luam hlau txhais tau hais tias cov nqi zoo tsis txaus los txhawb cov khoom lag luam. Txawm tias muaj kev pom zoo tshiab, kev tsim khoom yuav tsis pib rau kaum xyoo thaum ntxov.
Raws li qhov tshwm sim, lub hnub ci kev lag luam tuaj yeem ua rau 85-98% ntawm lub ntiaj teb cov nyiaj khaws cia los ntawm 2050, raws li kev tshawb fawb los ntawm University of New South Wales. Tus nqi ntawm cov nyiaj siv los tsim ib lub xov tooj ntawm tes yuav nce ntxiv thiab yuav siv sijhawm li tsib mus rau 10 xyoo kom rov qab mus rau qib tam sim no, kwv yees Brett Hallam, ib tus kws tshawb fawb sau ntawv.
Txawm li cas los xij, cov tuam txhab suav hnub ci tseem tab tom tshawb nrhiav qhov muaj peev xwm ntawm kev siv cov khoom pheej yig dua, xws li galvanized tooj liab, txawm hais tias tam sim no cov txiaj ntsig tau sib xyaw. Cov thev naus laus zis uas siv cov hlau pheej yig dua tau nce siab txaus los muab tso rau hauv ntau lawm sai tom qab cov nqi nyiaj nce siab, hais tias Zhong Baosheng, tus thawj coj ntawm lub ntiaj teb lub hnub ci vaj huam sib luag loj tshaj plaws Longi Green Energy Technology Co.
Nyiaj tam sim no ua lag luam nyob ib ncig ntawm $ 22.70 ib troy ounce. Tus nqi tau poob li ntawm 5% xyoo no tab sis tseem zoo dua qib uas nws tau nyob ua ntej qhov nce siab hauv xyoo 2020 vim tias muaj kev sib kis tau txhawb nqa kev thov.
Philip Klapwijk, tus thawj coj ntawm Hong Kong-based kws pab tswv yim Precious Metals Insights Ltd. tau hais tias "Kev hloov pauv nyiaj yuav ua rau muaj kev txaus siab ntau dua thaum nws nyob ib puag ncig $ 30 ib troy ounce, tsis yog $ 22- $ 23," said Philip Klapwijk, tus thawj coj ntawm Hong Kong-based kws pab tswv yim Precious Metals Insights Ltd. qhia. Nws yuav tsis muaj qhov "doomsday scenario" qhov twg peb tsis muaj nyiaj, tab sis "kev ua lag luam yuav rov sib npaug ntawm tus nqi siab dua," nws ntseeg.
