Lub photovoltaic vaj huam sib luag EL ntes yog ib hom cuab yeej uas siv los ntes photovoltaic vaj huam sib luag (lub hnub ci vaj huam sib luag). Nws yog raws li lub hauv paus ntsiab lus electroluminescence ntawm crystalline silicon. Electroluminescence (el) yog ib qho xwm txheej uas qhov hluav taws xob siv ua rau kev txav mus los ntawm cov neeg nqa khoom hauv cov npe ntawm cov khoom siv semiconductor nyob rau hauv qhov kev ua ntawm lub teb hluav taws xob, hloov ib feem ntawm lub zog kinetic mus rau hauv lub zog radiant. Lub photovoltaic vaj huam sib luag EL ntes siv lub hauv paus ntsiab lus no los ntes cov duab ze-infrared ntawm crystalline silicon los ntawm lub koob yees duab infrared siab thiab tau txais cov duab ntawm lub cell.
Lub luag haujlwm tseem ceeb ntawm lub vaj huam sib luag photovoltaic EL detector yog kom pom tseeb ntau yam tsis zoo ntawm lub vaj huam sib luag photovoltaic, cov kev ntsuas suav nrog lub rooj vag tawg, tawg, tawg, tawg, vuam braze, sintered mesh, dub core, Letter boxing, blending, low efficiency chip, Edge etching, PID, attenuation, hot spot attenuation, thiab lwm yam. Cov qhov tsis zoo no yuav cuam tshuam rau kev ua tau zoo thiab zoo ntawm cov vaj huam sib luag photovoltaic thiab, yog tias tsis pom thiab daws teeb meem raws sijhawm, yuav cuam tshuam tsis zoo rau kev ua haujlwm thiab kev ruaj khov ntawm tag nrho lub zog hnub ci.
Ntxiv rau qhov muaj peev xwm ntes tau qhov tsis zoo ntawm PV panels, PV panel EL detector muaj lwm yam zoo. Piv txwv li, nws muaj qhov tseeb thiab ua haujlwm tau zoo, tuaj yeem ntes tau qhov chaw thiab hom tsis zoo sai thiab raug. Ntxiv rau, EL detector muaj qhov zoo ntawm kev sim ua puas tsuaj uas nws yuav tsis ua rau lub photovoltaic panel puas tsuaj lossis cuam tshuam rau nws txoj kev ua haujlwm.
Cov duab xeem EL uas tsim nyog yog raws li nram no:
Nov yog qee qhov tsis zoo ntawm cov vaj huam sib luag photovoltaic:
Lub roj teeb tawg lawm
(1). Ua rau: lub vaj huam sib luag ntawm lub roj teeb tawg vim yog lub zog sab nraud thaum lub sijhawm vuam lossis kho; thaum qhov kub qis, lub vaj huam sib luag ntawm lub roj teeb tsis tau ua ntej kev kho, thiab tom qab lub sijhawm luv luv ntawm qhov kub siab, nws cia li nthuav dav, ua rau tawg; Lub roj teeb kub dhau thaum lub sijhawm vuam ib zaug lossis vuam ua ntu zus.
(2). Cov nyhuv ntawm module: nws ua rau lub zog ntawm lub module tsis muaj zog, thiab qhov kub ntawm qhov chaw yuav tshwm sim thaum lub module khiav ntev, uas yuav cuam tshuam ncaj qha rau kev ua haujlwm ntawm lub roj teeb kom txog thaum lub module raug hlawv thiab pov tseg.
(3). Kev tiv thaiv: thaum lub sijhawm vuam lossis ua kom tsis txhob muaj kev cuam tshuam ntawm cov rog sab nraud ntawm lub roj teeb phaj, thaum lub sijhawm vuam ib zaug lossis tandem ntawm lub roj teeb phaj rau kev kho cua sov ua ntej, qhov kub ua haujlwm ntawm cov hlau hluav taws xob yuav tsum ua tau raws li cov kev cai ntawm cov txheej txheem ntau lawm.
Rooj vag tawg
(1). Cov yam ntxwv ntawm EL imaging: los ntawm El daim duab, muaj cov kab ntsug ntawm ob kab grid, thiab muaj cov kab tsaus ntuj raws kab grid tseem ceeb ntawm lub cell. Tib lub sijhawm, qhov tsis muaj zog lub teeb lossis tsis ci ntsa iab ntawm cov grating nyias yog feem ntau yog los ntawm cov cell tsis txuas.
(2). Vim li cas: qhov laj thawj tseem ceeb ntawm kev puas tsuaj rau lub rooj vag yog qhov tawg ntawm lub rooj vag zoo thiab poob ntawm lub rooj vag zoo, uas ua rau txoj kab rooj vag tseem ceeb thiab txoj kab rooj vag zoo tsis tuaj yeem tsim lub voj voog. Tib lub sijhawm, lub grid tsis yog tus qauv vuam lossis roj teeb board luam ntawv, qhov zoo ntawm kev luam ntawv tsis zoo lossis cov kev teeb tsa luam ntawv tsis teeb tsa kom zoo, txiav silicon tsis sib npaug, ua yuam kev.
(3). Cov nyhuv ntawm module: thaum txo qhov ua tau zoo ntawm photovoltaic module, nws tsis zoo rau kev sau tam sim no.
(4). Kev tiv thaiv: kev teeb tsa cov qauv luam ntawv tsim nyog, kev sib sau ua ke ntawm cov khoom siv luam ntawv, kev tsim cov txheej txheem ua haujlwm ntawm cov vijtsam, kev saib xyuas tiag tiag RS tuaj yeem txo qhov tawg ntawm lub qhov rooj luam ntawv, tib lub sijhawm tuaj yeem nruab nrog lub tshuab cais tsis siv neeg rau kev saib xyuas online.
Ib daim dub
(1). Cov yam ntxwv ntawm EL imaging: hauv daim duab EL, koj tuaj yeem pom cov voj voog sib xyaw uas maj mam ci ntsa iab los ntawm qhov chaw nruab nrab mus rau ntug ntawm lub cell. Ib feem ntawm lub roj teeb yog dub thiab daim duab zoo li tsis muaj zog lossis tsis ci. Qhov no tsim ib thaj chaw sib xyaw ua ke, yog tias muaj hluav taws xob, qhov chaw nruab nrab ntawm lub roj teeb zoo li thaj chaw dub.
(2). Thaum lub sijhawm ua silicon rod crystallization, qhov sib cais siab ntawm silicon rod muaj feem cuam tshuam ncaj qha rau qhov solubility ntawm oxygen, thiab cov khoom siv silicon raug kuab paug rau ntau qib sib txawv, ua rau ib feem ntawm lub roj teeb tig dub. Tib lub sijhawm, vim yog lub sijhawm luv luv ntawm kev sib zog, qhov tso tawm cua sov latent thiab qhov kub thiab txias sib phim ntawm cov yaj tsis siab, qhov ceev ntawm kev loj hlob ntawm crystal tau nrawm dua, thiab qhov ua rau muaj qhov tsis zoo sab hauv yog kev ntxhov siab thermal ntau dhau.
(3). Kev cuam tshuam ntawm cov khoom: tom qab cov dub chip tshwm sim hauv cov khoom, qhov kev khiav ntev yuav ua rau muaj kev tawg thermal, thaum qhov kev xeem ntawm cov khoom IV yam ntxwv nkhaus, qhov nkhaus tshwm sim zoo li ntaiv, qhov kev khiav ntev yuav ua rau lub zog tso zis ntawm cov khoom poob qis.
(4). Kev tiv thaiv: kho qhov coagulation coagulation coefficient thiab solubility ntawm oxygen hauv silicon pas nrig kom tsis txhob muaj kuab paug ntawm cov khoom siv silicon.
Luv Circuit Dub Chip (tsis luv Circuit dub chip)
(1). Cov yam ntxwv ntawm EL imaging: cov photovoltaic modules hauv ib qho chaw yuav tshwm sim ib lossis ntau daim ntawm tag nrho-dub roj teeb.
(2). Ua rau: luv luv ntawm cov electrodes zoo thiab tsis zoo, vuam rov qab ntawm cov electrodes zoo thiab tsis zoo ntawm lub thawv diode, kev sib txuas tsis zoo thiab kev vuam virtual ntawm cov electrodes zoo thiab tsis zoo, thiab lwm yam, cov chav tsev cell sib xyaw ua haujlwm tsis zoo, thiab cov silicon wafers lossis N-type wafers tsis zoo raug siv tsis raug. Qhov tsis muaj PN junctions kuj yog ib qho ntawm cov laj thawj vim li cas EL imaging dub tag.
(3). Cov nyhuv ntawm cov khoom: cov coefficient ntawm kev sau thiab lub zog tso zis ntawm cov khoom yuav raug cuam tshuam loj heev. Lub zog tso zis ntawm tag nrho cov PV module raug txo qis, thiab lub zog siab tshaj plaws ntawm cov kab nkhaus IV raug txo qis.
(4). Kev ceev faj: thaum lub roj teeb raug vuam, cov hlau nplaum yuav tsum tso rau ntawm ntug kom tsis txhob muaj cov pob qij txha vuam thaum kub qis. Tom qab sib dhos tiav lawm, xyuas seb lub thawv diode puas tau vuam thiab seb cov hlau txhuas puas tau vuam tsis zoo.
Hauv ntej, lub photovoltaic vaj huam sib luag EL detector yog ib qho cuab yeej tseem ceeb rau kev ntes, thiab nws ua lub luag haujlwm tseem ceeb hauv lub zog hnub ci. Nws tsis tsuas yog txhim kho qhov kev hloov pauv photoelectric, txo tus nqi, txhawb kev txhim kho lub zog rov ua dua tshiab, tab sis kuj ua kom muaj kev ruaj khov thiab kev ua haujlwm ntawm lub zog hnub ci.
