Thaum lub hnub ci vaj huam sib luag tau lees paub tias yog lub ntsej muag ntawm lub zog tauj dua tshiab, ob peb sab nraum kev lag luam tsim khoom txaus siab rau lub luag haujlwm tseem ceeb uas ua los ntawm graphite heaters thiab tshav kub shields hauv kev tsim cov qib siab - zoo silicon wafers uas ua rau lub hnub ci hluav taws xob tsim tau. Cov txheej txheem graphite no tsim cov txheej txheem thermal tswj kom zoo rau silicon siv lead ua kev loj hlob, wafer doping, thiab nyias - cov txheej txheem tso rau hauv zaj duab xis, cuam tshuam ncaj qha rau cov khoom tsim tawm, kev siv hluav taws xob, thiab kev ua haujlwm ntawm lub hnub ci kawg.
Nyob rau hauv lub ntiaj teb no tshwj xeeb graphite kev ua lag luam rau photovoltaic daim ntaub ntawv, cov cua sov sawv cev rau ib tug loj tshaj plaws cov khoom ntu, tsim USD 966.22 lab nyob rau hauv cov nyiaj tau los thiab ntes 39.44% ntawm tag nrho cov kev ua lag luam qhia nyob rau hauv 2025, raws li PW Consulting kev tshawb fawb. Crucibles thiab pedestals ua raws li ntawm 32.83% (USD 804.40 lab), thaum tshav kub shields thiab rwb thaiv tsev cov khoom suav rau 17.56% (USD 430.20 lab). Qhov kev faib tawm no qhia txog qhov tseem ceeb ntawm kev tswj cov cua sov hauv txhua theem ntawm kev tsim hluav taws xob hnub ci.
Graphite heaters ua haujlwm ntawm lub hauv paus ntsiab lus ntawm kev tiv thaiv cua sov: thaum hluav taws xob tam sim no dhau los ntawm graphite, nws cov hluav taws xob tsis kam ua kom muaj cua sov sib npaug thiab ua tau zoo. Hauv Czochralski monocrystalline silicon furnaces, cylindrical graphite heaters ncig lub crucible sib dhos, ua kom kub txog li 1,500℃kom yaj polycrystalline silicon feedstock thiab tswj cov thermal gradients thaum siv lead ua rub. Tus qauv tsim ntawm cov cua sov no- suav nrog cov qauv qhov, phab ntsa tuab, thiab kev sib txuas hluav taws xob- yog ua tib zoo tsim los tsim qhov kub thiab txias profile uas xav tau rau qhov tsis xws luag -dawb siv lead ua loj hlob.
Qhov zoo ntawm graphite ua cov khoom siv cua sov yog ntau heev. Graphite tuaj yeem ua haujlwm ntawm qhov kub thiab txias ntau dua li cov khoom siv cua sov, nrog rau kev ua haujlwm tas li siab dua 2,000℃hauv inert cua. Nws muab cov thermal uniformity zoo, kom ntseeg tau tias cov silicon yaj yog rhuab sib npaug ntawm txhua sab. Graphite heaters kuj muaj lub neej ua haujlwm ntev thaum ua haujlwm zoo, tiv thaiv thermal qaug zog thiab tswj xyuas hluav taws xob zoo ib yam dhau ntau txhiab lub voj voog thermal. Qhov kev ntseeg siab no yog qhov tseem ceeb rau PV cov tuam txhab lag luam uas khiav cov phiaj xwm kev tsim khoom tas li uas lub lim tiam dhau los lossis lub hlis nruab nrab ntawm kev kaw qhov cub.
Graphite heat shields thiab thermal rwb thaiv tsev Cheebtsam ntxiv cov cua sov los ntawm kev tswj cov cua sov faib hauv qhov cub. Ntau- txheej graphite tshav kub tiv thaiv ib puag ncig ntawm thaj chaw kub, ua kom pom cov cua sov sab hauv thiab txo cov cua sov poob rau cov dej- cov phab ntsa cua sov. Qhov no txhim kho kev siv hluav taws xob zoo heev-los ntawm qee qhov kev kwv yees, kev ua kom zoo ntawm cov kab hluav taws xob graphite tuaj yeem txo cov hluav taws xob siv hluav taws xob los ntawm 20-30% piv rau cov qauv hluav taws xob tsawg dua. Cov ntaub thaiv cua sov kuj tseem pab tsim kom muaj qhov tseeb axial thiab radial thermal gradients uas tswj cov siv lead ua kev loj hlob thiab siv lead ua zoo.
Tshaj li qhov cub loj hlob siv lead ua, graphite heaters thiab susceptors yog siv nyob rau hauv downstream solar cell manufacturing txheej txheem xws li diffusion furnaces rau doping, PECVD systems rau anti-reflective txheej deposition, thiab annealing furnaces rau defect passivation. Hauv txhua daim ntawv thov, graphite qhov sib xyaw ua ke ntawm siab - qhov kub thiab txias, kev tsis sib haum xeeb, thiab kev ua haujlwm cua sov tsis zoo muab cov txheej txheem zoo dua piv rau lwm cov khoom siv cua sov.
Daim duab 1: Precision graphite heater tivthaiv rau photovoltaic siv lead ua kev loj hlob rauv, engineered kom xa cov thermal profiles thoob plaws silicon yaj.
Lub laub rau kev ua tau zoo dua hnub ci cell yog tsav kev nruam ntej hauv graphite cua sov tshuab. Raws li kev lag luam hloov pauv ntawm PERC mus rau TOPCon thiab HJT cell architectures, cov txheej txheem kub ua ntau dua thiab cov thermal uniformity yuav tsum nruj. HJT hlwb, tshwj xeeb tshaj yog, yuav tsum tau qis -kub plasma deposition txheej txheem qhov twg graphite electrodes thiab cov khoom siv cua sov yuav tsum muaj tshwj xeeb purity thiab seem stability.
Huixian Jincheng Abrasive & Graphite Mould Factory tsim thiab tsim cov khoom siv hluav taws xob graphite, cov khoom siv hluav taws xob, thiab cov khoom siv thermal rau cov khoom siv hluav taws xob photovoltaic. Raws li nyob rau hauv Huixian City, Henan xeev nrog kev ua hauj lwm yos rov qab mus rau 1984, lub tuam txhab ua ke sib sib zog nqus graphite khoom txawj ntse nrog advanced CNC machining muaj peev xwm xa cov cua kub daws optimized rau tej PV ntau lawm txheej txheem.
Jincheng Graphite tsim graphite cua sov los ntawm siab - ntom, siab - purity graphite qib xaiv rau lawv cov hluav taws xob zoo ib yam, zoo thermal shock resistance, thiab lub neej ua haujlwm ntev ntawm qhov kub siab. Lub tuam txhab ua haujlwm pab pawg ua haujlwm nrog cov neeg siv khoom txhawm rau txhim kho lub tshuab cua sov geometry, cov qauv qhov sib txuas, thiab cov qauv kev sib txuas kom ua tiav lub hom phiaj thermal profiles thiab lub zog xav tau. Nrog rau ntau tshaj 50 CNC tshuab ua haujlwm thiab qhov siab tshaj plaws machining qhov ntev ntawm 1,000 hli, Jincheng tuaj yeem tsim cov cua sov rau cov chaw sim me me thiab nruab nrab - nplai cov khoom siv lead ua.
Rau cov ntaub thaiv npog tshav kub thiab rwb thaiv tsev, Jincheng Graphite muaj ob qho tib si graphite cov khoom siv hluav taws xob tiv thaiv hluav taws xob thiab graphite- raws li cov khoom siv rwb thaiv tsev. Cov no yog cov precision-machined kom meej diameters thiab stacking configurations, kom ntseeg tau tias kev sib raug zoo nyob rau hauv lub cub tawg ua ke rau siab tshaj thermal efficiency. Lub tuam txhab lub tshuab nqus tsev impregnation txheej txheem ntxiv txhim khu kev ceev thiab txo cov hluav taws xob hloov hluav taws xob los ntawm cov khoom siv, txhim kho kev ua haujlwm ntawm rwb thaiv tsev tag nrho.
Kev tswj kom zoo yog qhov tseem ceeb tshwj xeeb rau cov khoom siv cua sov, vim tias cov khoom siv tsis sib xws tuaj yeem ua rau cua sov tsis sib xws, ua tsis tiav ntxov, thiab cov nqi tsim khoom poob qis. Jincheng Graphite siv cov kev sim nruj nrog rau kev ntsuas kev tiv thaiv, kev kuaj xyuas qhov ntom ntom, kev tshuaj xyuas qhov ntev, thiab siab - qhov ntsuas kub ua haujlwm kom ntseeg tau tias txhua lub tshuab cua sov muab kev ua tau zoo, txhim khu kev qha.
Raws li kev lag luam PV thoob ntiaj teb txuas ntxiv nws txoj kev nthuav dav sai, kev thov rau siab -cov khoom siv hluav taws xob graphite thiab cov khoom siv thermal yuav loj hlob nyob rau tib lub sijhawm. Cov qauv tseem ceeb shaping lub lag luam suav nrog kev hloov pauv mus rau qhov loj dua wafer hom (210mm thiab tshaj), uas yuav tsum muaj qhov loj dua qhov cub tawg thiab loj dua graphite kub cheeb tsam. Kev ua kom nrawm nrawm ntawm N- hom xov tooj ntawm tes thev naus laus zis kuj tseem txhawb nqa kev coj dawb huv thiab kev ua kom zoo dua qub. Rau cov tuam txhab graphite zoo li Jincheng Graphite uas tuaj yeem xa cov precision-engineered, siab- cov khoom siv thermal zoo, cov khoom siv PV tsim muaj ntau txoj hauv kev loj hlob nyob rau xyoo tom ntej.
