Lub hnub ci crystalline silicon nws tus kheej muaj lub zog tsis zoo thiab yooj yim tawg. Cov dej noo thiab cov pa phem hauv huab cua yuav maj mam oxidize thiab corrode lub electrode, uas tsis tuaj yeem tiv taus qhov xwm txheej ua haujlwm hnyav hauv huab cua qhib. Vim li no, cov hnub ci cell feem ntau yog ntim los ntawm iav photovoltaic los ntawm EVA thiab lub vaj huam sib luag tom qab. Cov iav photovoltaic hauv cov modules photovoltaic los tiv thaiv lub roj teeb los ntawm dej thiab roj yaig, thaiv cov pa oxygen los tiv thaiv oxidation, siab thiab qis kub tsis kam, rwb thaiv tsev zoo thiab laus tsis kam. Photovoltaic iav yog ib hom iav silicate nrog cov ntsiab lus hlau tsawg, tseem hu ua ultra-dawb embossed iav.
Cov iav photovoltaic siv rau hauv cov roj teeb silicon crystal txawv ntawm cov iav ntab. Qhov saum npoo ntawm cov iav photovoltaic yog suede, uas ua rau nws nyuaj rau lub teeb ncaj qha mus rau ntawm qhov chaw ntawm lub module los tsim cov specular reflection. Qhov saum npoo qis yog embossed, uas tuaj yeem txhim kho lub zog nplaum nrog EVA zaj duab xis.
Cov khoom tseem ceeb ntawm cov iav photovoltaic
Cov khoom siv tseem ceeb ntawm cov iav photovoltaic suav nrog cov xuab zeb quartz, cov tshauv soda, limestone, dolomite, sodium nitrate, ntsev glauber, sodium pyroantimonate, txhuas hydroxide, thiab lwm yam. Cov xuab zeb Quartz feem ntau ua lub luag haujlwm ntawm lub cev tsim network, qhov ntau npaum li cas feem ntau nyob rau feem ntau ntawm cov khoom siv iav, cov tshauv soda feem ntau yog siv los muab sodium oxide, feem ntau yog kom txo qhov kub yaj ntawm iav; Lub luag haujlwm tseem ceeb ntawm limestone yog kho qhov viscosity ntawm iav rau tus nqi tsim nyog, yog li ntawd lub sijhawm molding iav kom ua tau raws li qhov yuav tsum tau ua ntawm molding, ntsev glauber feem ntau yog siv los ua kom pom tseeb, siv los tshem tawm cov npuas hauv iav, los muab cov iav transmittance.
Photovoltaic iav raw khoom siv piv
Cov iav photovoltaic feem ntau yog npaj los ntawm txoj kev calendering, thiab cov txheej txheem ntau lawm tuaj yeem muab faib ua ob theem: kev tsim daim ntawv thiab kev ua tiav tob. Cov khoom tsim thawj zaug feem ntau suav nrog kev sib xyaw, yaj, calendering, annealing thiab txiav. Nyob ib ncig ntawm 1100 ℃ hauv cov txheej txheem dov, cov iav molten, lub calender rollers dov thiab txias, rau qee qhov ceev ncav cuag qee qhov tuab, qee qhov dav, qee qhov qauv, los ntawm lub iav ntawm tus nqi ntawm 91.5%, thiab tom qab ntawd tom qab annealing lehr, ua rau lub iav muaj qhov nkhaus kev ntxhov siab ruaj khov, kom muaj qee lub zog, tsis yooj yim tawg, yog qhov zoo rau kev txiav, ua cov iav. Nws yog qhov tsim nyog los taw qhia tias muaj qhov sib txawv ntawm cov kab ntau lawm ntawm photovoltaic embossed iav thiab ntab iav.
Cov txheej txheem ua tiav tob feem ntau yog cov iav thawj txheej thiab toughening, txheej yog los txhim kho qhov kev xa tawm ntawm cov iav photovoltaic, toughening yog los ua kom cov khoom siv kho tshuab ntawm iav, iav toughened khoov zog yog 3 ~ 5 zaug ntawm cov iav ib txwm muaj, lub zog cuam tshuam yog 5 ~ 10 zaug ntawm cov iav ib txwm muaj, txhim kho lub zog tab sis kuj txhim kho kev nyab xeeb.
Cov txheej txheem iav photovoltaic
Kev ua tau zoo ntawm 02 photovoltaic iav xav kom photovoltaic iav yuav tsum muaj lub teeb xa mus zoo. Feem ntau hais lus, lub teeb xa mus ntawm cov hlau tsis muaj txheej (wavelength ntau ntawm 380nm txog 1100nm) feem ntau yog ntau dua 91%, thaum lub teeb xa mus ntawm cov iav coated tom qab ua tiav tob tuaj yeem ncav cuag qib ntawm 93.5%. Tsis tas li ntawd, photovoltaic iav yuav tsum tau ua kom tau raws li qee yam kev tiv thaiv huab cua thiab cov khoom siv kho tshuab. Raws li GB T 30984.1-2015 "lub hnub ci zog iav ib feem 1 ultra-dawb embossed iav", qhov kev ua tau zoo tsawg kawg nkaus ntawm photovoltaic iav siv rau photovoltaic modules yuav tsum ua tau raws li cov kev cai hauv qab no.
Kev lag luam iav photovoltaic hauv Suav teb
Cov teeb meem ntawm kev lag luam iav photovoltaic siab dua, qhov concentration siab dua, kev tsim khoom xav tau kev paub dhau los ntev thiab cov txheej txheem tsim khoom ib zaug xwb, thiab xav tau kev nqis peev pib loj dua, lub peev xwm ntawm 900 tons / hnub photovoltaic iav kiln xav tau kev nqis peev pib RMB 9, 550 tons ntawm qhov cub siv li 3-400 lab yuan, thiab qhov cub loj muaj tus nqi tsim khoom qis dua piv rau qhov cub ib txwm (kev siv hluav taws xob tsawg txog 20%). Yog li ntawd, kev lag luam iav photovoltaic muaj qhov cuam tshuam loj, thiab cov thev naus laus zis molten loj feem ntau nyob hauv tes ntawm cov tuam txhab ua lag luam, Cov lag luam me thiab nruab nrab tsis muaj zog thiab lub zog nyiaj txiag los nqis peev hauv kev tsim kho 1000 tons ntawm kilns.
Txij li thaum Tuam Tshoj tau tawg qhov kev siv tshuab ntawm kev tsim cov iav photovoltaic hauv xyoo 2006, kev lag luam photovoltaic hauv tsev tau tsim kho sai hauv tsawg dua 10 xyoo. Tom qab vam khom rau kev xa khoom tuaj tag nrho, Tuam Tshoj tau dhau los ua tus tsim cov iav photovoltaic loj tshaj plaws hauv ntiaj teb. Ntau tshaj 90% ntawm lub ntiaj teb cov khoom siv silicon siv cov iav photovoltaic tsim hauv Tuam Tshoj. Piv nrog cov tuam txhab txawv teb chaws, Tuam Tshoj cov iav photovoltaic muaj qhov zoo ntawm qhov zoo thiab tus nqi. Txij li Lub Kaum Ob Hlis 2017, muaj 24 cov khoom siv iav dawb ultra-dawb, 40 lub qhov cub thiab 135 kab ntau lawm hauv Tuam Tshoj, nrog rau tag nrho cov peev xwm tsim khoom ntawm 21,290 tons / hnub. Xam raws li qib nruab nrab ntawm kev lag luam ntawm 78%, kev tsim khoom hauv tsev ntawm cov khoom siv iav dawb ultra-dawb calented yog li 14,773.20 tons / hnub.
Kev cia siab ntawm kev ua lag luam
Xyoo 2018 yuav yog thawj xyoo rau kev tso tawm cov khoom siv ob sab, thiab feem ntawm kev ua lag luam ntawm cov khoom siv ob sab yuav nce sai, uas yuav ua rau muaj kev xav tau iav photovoltaic. Raws li kev xam, qhov kev xav tau ntawm iav photovoltaic tau qhia hauv cov lus hauv qab no. Xav txog tias qee lub qhov cub iav photovoltaic qub xav tau kev kho txias hauv xyoo 2018, lub peev xwm tsim khoom tiag tiag ntawm iav photovoltaic yuav qis dua qhov peev xwm tsim khoom nominal, thiab kev muab thiab kev thov ntawm iav photovoltaic hauv xyoo 2018 yog nyob rau hauv qhov sib npaug nruj.
Raws li cov txiaj ntsig, txij li Q4 2017, kev muab khoom thiab kev thov ntawm cov iav photovoltaic tsis tshua muaj, thaum pib ntawm xyoo 2018, raws li lub hauv paus ntawm kev lag luam photovoltaic hauv thawj peb lub hlis twg yog lub caij tsis muaj, tus nqi ntawm cov iav photovoltaic nce siab, daim ntawv txheej yog 31 yuan ib square meter lossis ntau dua, tus nqi ntawm cov iav yog 21 yuan ib square meter lossis ntau dua, tus nqi ntawm cov nqi rov qab los yuav ua rau cov iav photovoltaic lag luam qib nyiaj tau zoo dua.
