Tam sim no, kev txhawb nqa ntawm cov hom phiaj ntawm cov pa roj carbon nruab nrab tau dhau los ua kev pom zoo thoob ntiaj teb, uas tau tsav los ntawm kev loj hlob sai ntawm kev thov rau PV, lub ntiaj teb PV kev lag luam txuas ntxiv txhim kho.Hauv kev sib tw ua lag luam hnyav zuj zus, cov thev naus laus zis tau hloov kho tas li thiab rov ua dua tshiab, qhov loj me thiab cov khoom siv hluav taws xob siab zog tau dhau los ua cov qauv tseem ceeb, ntxiv rau qhov zoo, tus nqi thiab lwm yam, kev tsim kho tshiab kuj yog lub hauv paus tseem ceeb ntawm kev tsim kho kev lag luam.

2023 Hnub Ci PV module innovation technology lub rooj sib tham ua ke los saib lub neej yav tom ntej tshiab ntawm PV module kev txhim kho
Thaum Lub Ib Hlis 31, 2023, "2023 Solar PV Module Innovation Technology Summit", tau tuav los ntawm cov xov xwm thoob ntiaj teb nto moo TaiyangNews, tau tuav raws li tau teem tseg.Ntau lub tuam txhab PV nto moo hauv tsev thiab txawv teb chaws tau sib sau hauv online los tham txog kev txhim kho ntawm PV module innovation technology.

Hauv lub rooj sib tham thev naus laus zis thev naus laus zis, Xia Zhengyue, tus thawj coj ntawm kev tsim cov khoom lag luam module ntawm Tongwei, tau raug caw los hais lus hu ua "Module Innovation los ntawm Ntiaj Teb Lub Tuam Txhab Loj Tshaj PV Cell", sib qhia cov qauv tshiab tshaj plaws ntawm kev lag luam tsim los ntawm Tongwei.Tsis tas li ntawd, TaiyangNews tau ua ib qho kev xam phaj nrog Dr. Xing Guoqiang, Tus Thawj Saib Xyuas Kev Ua Haujlwm ntawm PV ntawm Tongwei, los qhia Tongwei lub peev xwm tsim khoom, thev naus laus zis R & D thiab lwm yam ntsiab lus, thiab tos ntsoov rau yav tom ntej technology txoj kev txhim kho ntawm cov khoom module.

Kev tshuaj xyuas keeb kwm kev loj hlob ntawm Tongwei PV kev lag luam, Tongwei tau tsim 3 lub teb chaws thawj-chav kawm PV technology R & D chaw, tsom mus rau kev siv technology frontier, nws tus kheej tsim kev lag luam thawj 1GW 210 TNC cov kab ntau lawm, kev lag luam thawj qhov loj-loj advanced metallization xeem kab , nrog rau kev tsim cov hlwb tshiab thiab modules kev lag luam mainstream technology pilot kab, thiab lwm yam., mus txuas ntxiv innovation thiab txhaj tshuaj muaj zog vitality rau hauv kev lag luam kev loj hlob.

TOPCon thiab HJT dual txoj kev ua ntej nyob rau hauv parallel TNC thev naus laus zis kev tsim kho tshiab ua rau kev txhim kho tshiab
Tam sim no, PERC hlwb nyob ze rau qhov theoretical limit efficiency, thiab qhov feem ntawm N-hom hlwb yuav maj mam nce.Hauv kev xam phaj tshwj xeeb, Dr. Xing Guoqiang, Tus Thawj Saib Xyuas Kev Ua Haujlwm ntawm PV ntawm Tongwei, tau hais tias tam sim no, Tongwei tau nce mus rau qhov sib npaug nrog TNC thiab THC thev naus laus zis.Xav txog qhov xav tau tom ntej kom hloov pauv sai sai rau qhov kev xav tau ntawm kev lag luam, Tongwei qhov tam sim no module muaj peev xwm layout yog tsim los ua kom sib haum nrog cov xov tooj sib txawv thiab cov thev naus laus zis.

N-type technology yog nkag mus sai heev.Tus nqi, yield thiab stability ntawm conversion efficiency yog tus yuam sij rau N-hom loj ntau lawm.Nyob rau tib lub sijhawm, N-cov khoom lag luam kuj yog qhov kev txhawj xeeb tshaj plaws hauv kev lag luam ntawm tus nqi thiab muag tus nqi.Los ntawm kev hloov kho thev naus laus zis txuas ntxiv thiab kev tsim kho tshiab, tam sim no TNC high-efficiency module nrog 182-72 ob chav iav piv txwv tuaj yeem ua kom lub zog ntau dua 20W piv nrog cov khoom siv PERC, thiab muaj li 10% siab dua bifacial tus nqi tshaj PERC.Yog li ntawd, TNC high-efficiency modules twb tau kev lag luam thiab yuav dhau los ua ib tiam tshiab ntawm cov khoom lag luam uas coj cov khoom siv hluav taws xob ntau dua, kev ntseeg siab dua thiab txo qis rau cov nroj tsuag hluav taws xob.

Raws li ib tug ntawm cov thawj coj manufacturers nkag mus rau hauv lub HJT teb, lub siab tshaj plaws R & D efficiency ntawm Tongwei lub HJT hlwb tam sim no tau mus txog 25.67% (ISFH ntawv pov thawj).Ntawm qhov tod tes, kev ua tiav daim ntawv thov ntawm tooj liab kev sib txuas tshuab tau kuj txo tus nqi metallization ntawm HJT.Tam sim no, HJT thev naus laus zis nrog kev hloov pauv siab ua haujlwm, qis qis thiab lwm yam zoo tau muab kev cia siab siab los ntawm kev ua lag luam, tab sis txwv los ntawm tus nqi siab ntawm kev nqis peev tseem tsis tau ua rau tawg.Nrog rau qhov tseem ceeb ntawm kev ua haujlwm ntawm tes thiab kev nce qib ntawm cov xwm txheej ntau lawm, qhov ua ntej ntawm Tongwei's HJT thev naus laus zis layout tau dhau los ua ntau thiab pom tseeb, thaum "txo cov nqi thiab nce kev ua tau zoo" nrog ob txhais tes, HJT yuav ua rau lub hauv paus tseem ceeb hauv nws txoj kev loj hlob.

Tsis tas li ntawd, txij li xyoo 2020, Tongwei tau tsim nws tus kheej tsim "TNC" (Tongwei N-passivated hu xovtooj) thev naus laus zis, thiab tam sim no kev hloov pauv ntau ntawm TNC hlwb tau tshaj 25.1%.Raws li Xia Zhengyue, TNC cell muaj siab bifacial tus nqi, tsis tshua muaj attenuation, zoo kub coefficient, zoo teb rau tsawg lub teeb thiab lwm yam zoo, nws tus kheej tsim 182 loj 72 version hom ib nrab-daim ntawv module zog mus txog 575W +, siab tshaj PERC 20W + , 10% siab dua bifacial tus nqi, tau mus txog qib kev lag luam.Lub bifacial modules tsim nrog cov thev naus laus zis no muaj 3-5% siab dua qhov nruab nrab lub zog tsim hluav taws xob nce ib watt dua li cov qauv PERC bifacial, tiag tiag ua tiav kev tsim hluav taws xob siab.

Tongwei's high-efficiency modules coj mus rau hauv tus account qhov zoo ntawm cov khoom sib txawv kom ua tiav ntau yam kev siv npog txhua qhov xwm txheej.Piv txwv li, 182-72 cov khoom uas muaj qhov zoo ntawm qhov system yog xaiv rau cov xwm txheej loj hauv av;182-54 cov khoom uas muaj siab rhiab heev rau qhov yuav tsum tau loj tuaj yeem xaiv rau cov xwm txheej hauv tsev.

Nrog rau qhov zoo ntawm silicon cell ob tus thawj coj, Tongwei txoj kev sib koom ua ke ntsug yog ua tiav
Xyoo 2022 yog xyoo tshwj xeeb rau Tongwei cov ntu ntu.Thaum Lub Yim Hli, Tongwei tshaj tawm qhov nrawm ntawm nws cov qauv kev lag luam teeb tsa thiab kev ua tiav sai ntawm nws cov phiaj xwm nthuav dav, txhawb nqa cov txheej txheem ntsug ntawm nws txoj kev lag luam PV;txij thaum ntawd los, nws tau ua tiav yeej ntau ntawm cov phiaj xwm kev sib tw ntawm cov lag luam hauv nruab nrab hauv xeev;Thaum Lub Kaum Hli, Tongwei tshaj tawm tias tag nrho cov kab ntawm nws cov nplais pobzeb Terra modules tau dhau daim ntawv pov thawj carbon hneev taw uas tau muab los ntawm Fab Kis txoj cai Certisolis Lub Kaum Hli, Tongwei tshaj tawm tias nws cov kab tag nrho ntawm cov nplais pobzeb Terra modules tau txais daim ntawv pov thawj carbon footprint los ntawm Certisolis. , ib tug Fabkis txoj cai;Thaum lub Kaum Ib Hlis, Tongwei tus kheej tsim TNC high-efficiency cell innovation technology tau muab tsub nqi raws li ib qho ntawm kaum lub tswv yim tshiab ntawm "Zero Carbon Tuam Tshoj" hauv 2022;Tom qab ntawd, nws tau raug suav tias yog Tier 1 ntawm BNEF daim ntawv teev npe thoob ntiaj teb PV Tier 1 module manufacturers nyob rau lub quarter thib plaub ntawm 2022, tag nrho xav txog kev lag luam kev paub txog Tongwei cov kev ua haujlwm siab.Qhov no qhia txog kev ua lag luam kev lees paub ntawm Tongwei cov kev ua haujlwm siab.

Raws li Dr. Xing Guoqiang, lub module muaj peev xwm ntawm Tongwei yuav ncav cuag 14GW nyob rau hauv 2022, thiab tag nrho cov module muaj peev xwm yuav tsum ncav cuag 80GW thaum kawg ntawm 2023. Lub hauv paus ruaj khov rau kev loj hlob sai ntawm kev lag luam module.

Qhov kev sib tw khaus ntau dua, qhov muaj zog ntawm kev tsim kho tshiab;qhov loj ntawm kev lag luam nplai, qhov tseem ceeb tshaj lub tsev ntawm kev sib tw, ntsib kev lag luam loj hlob sai, Tongwei tseem muaj kev txiav txim siab mus rau pem hauv ntej thiab ua cov kauj ruam loj thiab khov kho.Nyob rau hauv lub neej yav tom ntej, Tongwei yuav txuas ntxiv txhim kho nws cov thev naus laus zis tshiab lub zog, ntxiv dag zog rau nws cov kev sib tw tag nrho, muab cov khoom siv tau zoo thiab cov khoom zoo rau cov neeg koom tes sab saud thiab qis qis, thiab pab ntsuab zog kev loj hlob thiab tsim ib tug tshiab ecology ntawm sustainable PV kev lag luam.
