TOPCon? Heterojunction?
Apr 11, 2022
Tsis ntev los no, Tongwei Co., Ltd. tshaj tawm tias nws npaj yuav nqis peev 12 billion yuan los tsim 32GW high-efficiency crystalline silicon roj teeb project hauv Tianfu New District, Meishan, Sichuan. Qhov project yuav raug siv nyob rau hauv ob theem. Thawj theem ntawm 16GW roj teeb qhov project muaj peev txheej ntawm 6 billion yuan, thiab sib zog ua kom muab tso rau hauv kev tsim khoom ua ntej lub Kaum Ob Hlis 2023. Qhov thib ob ntawm 16GW roj teeb qhov project yuav pib ua raws li kev pom zoo.
Thaum qhov kev xaiv ntawm heterojunction thiab TOPCon tau nkag mus rau hauv kev sib tshuam, Tongwei puas xaiv heterojunction lossis TOPCon rau qhov kev nqis peev no? Nws tau dhau los ua qhov tseem ceeb ntawm kev saib xyuas uas cov kev lag luam photovoltaic thiab cov tuam txhab peev txheej yuav tsum nkag siab.
TOPCon, Heterojunction ntawm Txoj Kev Hla
TOPCon thiab HJT yog ob txoj kev siv roj teeb tseem ceeb, thiab lawv qhov kev hloov pauv hauv chav sim tau hloov kho tas li. Tsis zoo li Huasheng, Risen Zog, Akcome, thiab lwm yam, uas tsom rau heterojunctions, thiab Jolywood, Jinko, Tianhe, thiab lwm yam, uas tsom rau TOPCon, Tongwei ib txwm taug kev ntawm ob txhais ceg hauv kev xaiv heterojunction thiab TOPCon. .
Thaum kawg ntawm 2021, Tongwei tshaj tawm tias raws li kev tshawb fawb thiab kev loj hlob ntawm nws cov heterojunction, lub tuam txhab tau tsim ib tug tshiab 1GW heterojunction pilot kab thiab ua tiav ib tug ramp-up nyob rau hauv ntau lawm muaj peev xwm. Lub tuam txhab yuav tsom mus rau kev txhim kho kev ua tau zoo nyob rau hauv cov xwm txheej ntawm cov khoom loj loj ntawm heterojunction Lub hom phiaj ntawm kev txo nqi yog kom ua tiav kev tshawb fawb thiab kev loj hlob.
Thiab Tongwei tsis tau tso tseg rau TOPCon thev naus laus zis. Hauv ob xyoos dhau los, Zhongtongwei Hnub Ci thiab Jiangsu Microconductive Nano Equipment Technology Co., Ltd. tau ua ntau yam kev sib txuas lus thiab kev sib tham txog cov ntsiab lus ntawm kev koom tes nrog TOPCon project, thiab ua txhua yam kev sib pauv ntawm cov teeb meem kev koom tes. Thaum Lub Xya Hli 2021, ob tog tau txais kev pom zoo thiab kos npe rau daim ntawv cog lus koom tes. Nws cia siab tias thaum kawg ntawm 2022, Tongwei yuav tsum tsim kom muaj 1GW TOPCon pilot kab.
Txawm li cas los xij, rau qhov kev npaj tshiab 32GW roj teeb muaj peev xwm ntawm Meishan lub hauv paus lub sijhawm no, Tongwei tsis tau qhia meej txog txoj kev uas nws yuav txais yuav. PERC thev naus laus zis txoj hauv kev uas tau tsim nyob rau hauv Meishan puag ua ntej yog tag nrho cov kev paub tab PERC thev naus laus zis hauv kev lag luam tam sim no. Hais txog kev nqis peev tshiab, ib tus neeg cuam tshuam los ntawm Tongwei hais rau xov xwm: "Txoj kev siv tshuab tseem tsis tau txiav txim siab."
2. Puas yog TOPCon lossis heterojunction?
Txawm hais tias Topcon thiab HJT heterojunctions yog ob qho tib si ua tau, los ntawm cov peev nyiaj tshaj tawm los ntawm Tongwei Co., Ltd., thawj theem ntawm 16GW tau nqis peev 6 billion yuan, uas yog sib npaug rau chav tsev peev ntawm 375 lab yuan. Tus nqi peev ntau dua li ntawm PERC, thiab nws tsis tuaj yeem muab piv nrog PERC. Topcon los yog heterojunction txuam.
Raws li kev tshawb fawb kev lag luam hauv xyoo 2021, tus nqi ntawm PERC cov kab tshiab yog kwv yees li 150 lab / GW, TOPCon txoj kab tshiab ncaj qha yog kwv yees li 230 lab / GW, kev txhim kho los ntawm PERC yog 60-070 lab / GW, thiab unit peev ntawm heterojunction ntau lawm kab yog siab li 4.3 -450 lab/GW. Txawm li cas los xij, Junshi Energy tshaj tawm hauv 2021 tias kev nqis peev hauv heterojunction ntau lawm kab hauv 2022 tuaj yeem ncav cuag 350-380 lab / GW.
Nrog Tongwei lub peev xwm "nqa lub kov" nyob rau hauv lub electromagnetic teb (nws yog Tongwei lub peev nyob rau hauv heterojunction peb lub xyoos dhau los uas ua rau lub upsurge ntawm localization ntawm heterojunction khoom, thiab ua rau Meyer Burger tshem tawm ntawm Suav lag luam, ncaj qha los ntawm Heterojunction khoom manufacturers yog hloov mus rau cov tuam txhab roj teeb), Tongwei tuaj yeem txo qhov peev ntawm heterojunction ntau lawm kab rau 350-380 lab yuan / GW.
Thiab qhov no yog lub peev xwm peev peev ntawm Tongwei kev nqis peev hauv qhov kev nthuav dav no. Los ntawm qhov kev xav no, nws zoo li Tongwei yuav xaiv qhov heterojunction rau qhov kev nthuav dav no.
Raws li kev txheeb xyuas kev lag luam, thaum TOPCon thiab heterojunctions nthuav dav zuj zus, tsis hais leej twg yeej, PERC yuav ntsib kev tawm ntawm kev lag luam hauv 2-3 xyoo tom ntej. Txawm li cas los xij, Tongwei tsis ntev los no tau nthuav dav nws cov peev txheej PERC los ntawm 7.5GW hauv nws lub hauv paus Meishan thiab Jintang puag. Yog tias nws tsis yog rau kev hloov pauv mus rau TOPCon yav tom ntej, cov kev nqis peev no yuav tsis muaj sijhawm los txo nqi. Ua ke nrog Tongwei lub peev xwm PERC uas twb muaj lawm, yog Tongwei xav tsim TOPCon ntawm qhov loj, nws tuaj yeem hloov kho thiab hloov pauv cov peev txheej PERC uas twb muaj lawm txhua lub sijhawm thiab nyob qhov twg, thiab nws tsis tas yuav nqis peev hauv TOPCon ntawm qhov loj.
3. Pov npav, koj txiav txim siab tias Tongwei ua dab tsi
Tongwei Co., Ltd. tau hais tias lub tuam txhab tseem ceeb heev rau kev tshawb fawb thiab kev loj hlob ntawm solar cell technology, thiab tau ua loj-scale kev tshawb fawb thiab kev loj hlob peev nyob rau hauv tshiab roj teeb technology teb xws li HJT thiab TOPCon, thiab tau ua tiav kev tshawb fawb thiab kev loj hlob tshwm sim. Nyob rau hauv lub neej yav tom ntej, lub tuam txhab yuav raws sij hawm qhia tshiab roj teeb technology rau loj-scale ntau lawm, ntxiv txhawb txoj kev loj hlob qauv ntawm loj loj thiab thinning, txhim kho cov kev ua tau zoo ntawm cov nqi ntawm cov khoom siv technology tshiab, thiab tsis tu ncua consolidate lub tuam txhab kev sib tw nyob rau hauv lub teb ntawm hnub ci hlwb.
Tab sis txawm tias nws yog heterojunction lossis TOPCon, cov khoom siv roj teeb yuav yog thawj tus tau txais txiaj ntsig. Dab tsi ntawm cov cuab yeej koj xav tias yuav yog 32GW roj teeb ntau lawm kab nqis peev los ntawm Tongwei lub sijhawm no?
