1. Tom qab kev ua haujlwm ntawm lub hnub ci tivthaiv tiav, qhov kev ntsuas hluav taws xob tau ua tiav, thiab lub zog tivthaiv yog qhov qub, tab sis cov neeg siv khoom tau txais lub zog txo qis thaum cov khoom siv tau nruab thiab ua haujlwm. Feem ntau ntawm qhov tshwm sim no tshwm sim los ntawm photolithosis ntawm lub roj teeb.

Kab lus no yuav systematically, luv luv piav qhia txog qhov tshwm sim ntawm photoloration. 2. Photoelectric attenuation ntawm photovoltaic Cheebtsam yuav muab faib ua ob theem: thawj photolithonal lwj thiab laus attenuation.

2.1 Qhov pib photolithoma thawj zaug photolithosis, uas yog, cov zis hluav taws xob ntawm photovoltaic module muaj qhov poob loj nyob rau hauv thawj hnub ntawm kev siv thawj zaug, tab sis tom qab ntawd zoo li stabilize. Ib qho laj thawj tseem ceeb uas ua rau muaj qhov tshwm sim no yog qhov borogenic complex nyob rau hauv p-hom (borborid) crystalline silicon txo qis.

Los ntawm kev hloov p-hom dopant, lub photovollection ntawm photovollection yog txo kom zoo los ntawm kev hloov boron; los yog daim ntawv roj teeb yog preconwarding, uas yog thawj zaug photolithonal attenuation ntawm lub roj teeb ua ntej lub rooj sib txoos. Nws tuaj yeem tswj tau nyob rau hauv ib qho me me thaum tseem txhim kho qhov tso zis ruaj khov ntawm cov khoom siv. Photocatalysts muaj feem xyuam nrog cov roj teeb pob, thiab lub ntsiab lus ntawm cov tuam txhab tsim khoom yog xaiv cov roj teeb zoo kom txo tau qhov cuam tshuam ntawm photoloration.

2.2. Kev laus attenuation aging poob yog hais txog lub zog qeeb qeeb hauv kev siv mus sij hawm ntev, thiab qhov tseem ceeb ntawm lub roj teeb muaj feem cuam tshuam nrog kev txo qis ntawm lub roj teeb, thiab nws tseem cuam tshuam rau kev ua haujlwm ntawm cov khoom siv pob.

Ntawm lawv, nws yog ib qho tseem ceeb vim li cas rau degradation ntawm kev tiv thaiv kev ua tau zoo thaum lub sij hawm irradiation ntawm ultraviolet lub teeb. Lub sij hawm ntev irradiation ntawm ultraviolet rays, tso cai rau EVA thiab backplane (TPE qauv) muaj hnub nyoog daj-hloov tshwm sim, ua rau lub teeb transmittance ntawm lub rooj sib txoos poob, thiab ua rau lub hwj chim poob. Qhov no yuav tsum tau hais tias cov neeg muag khoom yuav tsum nruj me ntsis tswj thaum xaiv EVA thiab backplanes, thiab cov ntaub ntawv xaiv yuav tsum tau zoo heev nyob rau hauv kev laus tiv thaiv kom txo tau cov aggregate txo vim aggregate aging.

3. Cov duab thaum ntxov attenuation tshwm sim ntawm p-hom (borborid) siv lead ua silicon hnub ci cell tau pom ntau dua 30 xyoo dhau los, thiab tom qab ntawd tib neeg tau ua ntau yam kev tshawb fawb. Tshwj xeeb, nyob rau hauv xyoo tas los no, kev tshawb fawb tshawb fawb pom tias nws muaj feem cuam tshuam nrog boron oxygen concentration hauv silicon wafer, thiab txhua tus neeg pom zoo ib yam yog illuminated los yog tam sim no inhibiting boron thiab oxygen nyob rau hauv silicon wafer los tsim boron oxygen complexes, yog li txo tus me nyuam lub neej Txawm li cas los xij, tom qab annealing, lub neej tsawg dua tuaj yeem rov qab tau cov tshuaj tiv thaiv , silicon-muaj silicon zaj duab xis yuav muaj qhov sib txawv ntawm kev lwj tom qab lub teeb, thiab boron, oxygen hauv silicon wafer.

Qhov loj dua cov ntsiab lus, ntau cov boraboalaxic composites uas tshwm sim nyob rau hauv lub cev nyob rau hauv illumination los yog tam sim no qhov teeb meem, qhov ntau dua qhov nce nyob rau hauv lub neej qis tshaj. Hauv cov pa oxygen tsawg, sib xyaw ua ke, phosphorous silicon wafer, nws lub neej colossono tau nce ntxiv nrog lub sijhawm tshiab ntawm kev yees duab, tag nrho cov kev puas tsuaj me me heev. 4.

Kev daws 4.1. Txhim kho qhov tshwm sim thaum ntxov photolithix ntawm kev ua tau zoo ntawm silicon ib leeg siv lead ua zoo hnub ci Cell tseem ceeb ntawm ib leeg siv lead ua silicon hnub ci hlwb, thiab thaum ntxov photolithonal attenuation amplitude ntawm kev hloov dua siab tshiab yog me me.

Yog li, cov khoom ntawm silicon phaj nws tus kheej txiav txim siab txog qib ntawm photorelation thaum ntxov ntawm lub hnub ci cell kev ua haujlwm. Yog li ntawd, los daws qhov teeb meem ntawm photolithosis thaum ntxov ntawm cov khoom siv photovoltaic. Nws yog ib qho tsim nyog los daws qhov teeb meem silicon.

Cov hauv qab no yuav tham txog ntau txoj hauv kev. A. Qhov zoo ntawm qee cov khoom siv lead ua uas txhim kho cov boron-doped ncaj ib leeg siv lead ua silicon pas nrig yog kev txhawj xeeb tiag tiag.

Yog tias qhov xwm txheej no yuav cuam tshuam rau kev noj qab haus huv ntawm kev lag luam photovoltaic hauv kev sib xyaw ntawm Dragonflite ib leeg siv lead ua khoom Txhim kho cov teeb meem thiab kev txhim kho hauv Suav teb: 1) Txij li thaum thawj high-purity polycrystalline silicon tsis txaus, qee lub tuam txhab rub qws tau sib xyaw qee qhov loj ntawm macerates uas yuav tsum tsis txhob siv thiab lwm yam teeb meem impurities. Lub hnub ci roj teeb uas tsim los siv cov ntaub ntawv zoo li no tsis yog tsuas yog ua haujlwm tsawg xwb, tab sis thaum ntxov photolithosis loj heev. Peb thov kom cov khoom siv silicone tsis zoo.

2) Khib N-hom silicon wafers hauv high-purity polycrystalline silicon blends hauv high-purity polycrystalline silicon cov ntaub ntawv, thiab lwm yam. Lub boron silicon pas nrig tsim yog ib qho nyiaj siab P-hom ib leeg siv lead ua khoom. Txawm hais tias qhov kev tiv thaiv yog tsim nyog, boron oxygen concentration yog siab heev, uas ua rau lub photolithonal attenuation loj dua ntawm lub hnub ci cell kev ua tau zoo.

Peb xav kom tsis muaj kev tiv thaiv qis N-hom silicon. 3) Qee lub tuam txhab rub cov txheej txheem pas nrig tsis txwv, cov ntsiab lus oxygen hauv crystalline silicon siab dhau, qhov kev ntxhov siab sab hauv yog loj, qhov tsis xws luag dislocation yog siab, thiab cov resistivity tsis sib xws, txhua yam cuam tshuam rau kev ua haujlwm thiab kev ruaj ntseg ntawm lub hnub ci. Peb xav txhim kho cov khoom siv rub tawm.

Tswj cov pa oxygen. Lub hnub ci ntawm lub hnub ci ua los ntawm cov silicon wafer saum toj no muaj qhov loj dua photolithonal attenuation, uas yuav dhau ntawm cov neeg siv khoom tau txais. Qhov tseeb, qhov ncaj rub ib leeg siv lead ua txheej txheem yog paub tab.

Tsuav yog peb muab cov khoom zoo, raws li tus txheej txheem pas nrig, qhov zoo ntawm silicon pas nrig tuaj yeem tswj tau zoo dua. B. Txhim kho ib leeg siv lead ua silicon pas nrig khoom zoo Cov txheej txheem no tuaj yeem tsis tsuas yog tswj cov pa oxygen concentration hauv ib leeg xwb, tab sis kuj txhim kho cov silicon ib leeg siv lead ua, radial resistivity uniformity.

Cov txheej txheem tau pib sim hauv Suav teb. C. Txhim kho Ib Leeg Crystal Silicon Txheej Txheem (FZ) txhawm rau txhim kho cov txheej txheem ib leeg siv lead ua silicon los ntawm lub regional molten ib leeg siv lead ua silicon txheej txheem (Fz) los tiv thaiv ntau cov pa oxygen hauv cov kua silicon siv lead ua hauv cov txheej txheem rub ncaj, yog li kev daws teeb meem P-hom (boron boron) Thaum ntxov photolithix tshwm sim ntawm lub hnub ci hlwb.

Vim yog tus nqi siab ntawm FZ, nws yog ib qho tseem ceeb rau silicon wafers rau IC thiab lwm yam khoom siv semiconductor, tab sis qee lub tuam txhab tau kho cov txheej txheem FZ, txo cov nqi. Ua los ntawm hnub ci roj teeb silicon wafers. Qee cov pas nrig hauv tsev tau ua tiav qhov no ntawm kev sim ua haujlwm D, hloov dopant, siv lub roj teeb ua los ntawm silicon-doped silicon nrog ballium, tsis pom qhov tshwm sim thaum ntxov photorealic ntawm lub hnub ci cell, tab sis kuj tau daws qhov pib ntawm lub hnub ci cell.

Ib txoj hauv kev. E, siv p-type N-type silicon-doped N-hom silicon daim ntawv siv silicon wafer thiab ib txoj hauv kev los daws qhov teeb meem ntawm kev sim thawj zaug ntawm lub roj teeb, tab sis los ntawm cov kev lag luam tam sim no muaj kev lag luam luam ntawv 诰 roj teeb txheej txheem, 诰Tsis muaj qhov zoo dua hauv kev hloov pauv thiab cov nqi tsim khoom. Qee cov txheej txheem tseem ceeb yuav tsum tau daws 4.

2. Lub illumination attenuation yav dhau los ntawm lub roj teeb yog tshwm sim los ntawm cov duab thaum ntxov attenuation ntawm lub photovoltaic los ua ke, thiab lub roj teeb yog illuminated. Plearance, kom lub photoa thaum ntxov ntawm lub roj teeb tshwm sim ua ntej cov khoom tsim.

Thaum ntxov photolithonization ntawm photovoltaic Cheebtsam yog me me, tuaj yeem tswj tau hauv kev ntsuas qhov yuam kev. Nyob rau tib lub sij hawm, nws kuj zoo heev txo lub caij nyoog ntawm kub qhov chaw nyob rau hauv photovoltaic Cheebtsam. 5.

Cov ntsiab lus nce cov zis ruaj khov ntawm cov khoom siv photovoltaic, nqa cov txiaj ntsig ntau dua rau peb cov neeg siv. Txawm hais tias lub teeb pom kev zoo, nws yog ib txoj hauv kev ntxiv rau cov neeg raug kaw, tab sis ua ntej qhov zoo ntawm silicon wafer tsis zoo, kev siv cov qauv no yog los daws cov kev ntsuas tau zoo rau cov khoom siv photovoltaic thaum ntxov.
