Cov khoom siv tseem ceeb ntawm PV, Heraeus Photovoltaics tau pib rau, ntxiv rau tiam tom ntej, kev ua tau zoo tshaj metallization pastes ntawm SNEC PV Power Expo 2019.
Heraeus yog qhia txog nws cov SOL966X series ntawm cov khoom siv hlau metallis uas yog tsim los ua kom tiav cov theem ntawm kev hloov xov tooj ntawm tes thiab muab kev lag luam zoo tuaj rau ntau cov kev xav tau kev lag luam, qhov zoo tshaj plaws rau cov PERC solar cells.
Martin Ackermann, Thawj Tswj Hwm ntawm Heraeus Photovoltaics, tau hais tias, "PV kev lag luam yuav tsum txo qis dua tus nqi ib-qhov nqi dua lwm lub zog. Peb cov khoom siv tshiab tshaj plaws ua qhov txiaj ntsig, kev tsim kho thiab kev lag luam ntawm cov xovtooj ntawm tes yuav tsum txhim kho kev ua tau zoo thiab txo tus nqi ntawm cov hluav taws xob, uas yuav ua kom lub hnub ci zog txais kom ncav cuag lub ntiaj teb lus taw qhia. "
Heraeus hais tias nws cov SOL9661B muab tshuaj yog tsim los rau kev ua haujlwm siab PERC hnub ci siv ultra fine-screen luam tawm hauv tsawg dua 26μm npo qhib hauv siab dhau los ntau lawm.
Cov txheej txheem tshuaj txhuam hniav yog hais tias kom muaj cov cim tshwj xeeb uas tuaj yeem raug rau hluav taws kub ntawm lub ncov qis thiab ntawm qhov kub kub ntau. uas muab kev tiv thaiv ntawm emitter thaum lub sij hawm tua firing. Raws li qhov tseeb, hu rau kev ua tau zoo tuaj yeem nrog hauv Isc (luv luv Circuit Court tam sim no) thiab FF (qhov kev sau sib tw), ob qho tib si tib lub sijhawm.
The SOL9662B Series muab tshuaj yog tsim los rau ob chav luam ntawv uas muaj kev tiv thaiv ntxiv rau thaj chaw laser, piv rau yav dhau los iterations. Qhov no, nrog rau txoj kev txhim kho tshiab hauv cov khoom nruab nrog cev hauv UFL (Ultra-Fine-Line) tau hais tias ua rau Voc thiab Isc nce siab.
Heraeus tau qhib lub SOL9661B2 series metallization paste rau 'dual passivation' hnub ci hlwb. SOL9661B2 tau hais tias kom muaj cov cim tshwj xeeb uas tau nkag mus rau cov tshooj ntawm cov khoom tso tawm thiab tau hu rau ULDE (~ 10-19 dopant concentration) thiab txo cov ntaub ntawv pov thawj. Vim li ntawd, SOL9661B2 muab FF thiab Voc dua, boost PERC cell efficiency.
Lub tuam txhab kuj tau qhia txog SOL9661D series muab tshuaj, tshwj xeeb rau DWC / MCCE, uas yog tsim los muab kev nplua rau ntawm Knotless npo luam tawm tsis muaj kev txhawj xeeb hauv kev ua khoom loj.
Lub SOL9380 series muab tshuaj txhim kho yog tsim rau cov n-hom hnub ci qis, uas tau hais kom muaj kev txhim kho tseem ceeb hauv xovtooj Voc thaum tswj los yog kev txhim kho kev xav tau.
Nrog rau kev lag luam nce siab hauv Tuam Tshoj rau TOPCon (Tunnel Oxide Passivated Contact) Hnub ci hlwb, Heraeus tau qhib lub SOL7200 series muab tshuaj, ua kom tsis muaj hluav taws kub, vim muaj cov txheej txheem ultra-thin uas txhawb siab heev Voc ntawm lub hnub qub, tshwj xeeb iav Science News for KIDS.
Heraeus kuj tau npaj ntsej muag rau ntawm 'Floating busbars' los ntawm nws cov SOL6700 series muab tshuaj, uas tau hais tias muaj ib lub khob tshiab iav thiab paste additives pab txo qeej ntawm cov emitter thaum lub txheej txheem metallization thiab cia siab ntawm cell efficiencies ntawm 22 +%, Voc li zoo li module kev ntseeg, raws li lub tuam txhab.
