Kev faib cov iav photovoltaic: Photovoltaic iav substrates rau lub hnub ci hlwb feem ntau suav nrog cov iav ultra-thin, iav nto-coated, thiab cov ntsiab lus hlau tsawg (ultra-dawb) iav. Raws li qhov xwm txheej ntawm kev siv thiab kev tsim khoom, cov iav photovoltaic tuaj yeem muab faib ua peb yam khoom, uas yog lub hau npog ntawm lub hnub ci vaj huam sib luag, uas feem ntau yog dov iav; qhov saum npoo ntawm cov iav tiaj tus yog coated nrog cov khoom siv semiconductor nrog lub thickness ntawm tsuas yog ob peb microns Conductive substrate rau nyias-film roj teeb; iav rau lo ntsiab muag lossis iav siv hauv cov tshuab photovoltaic. Cov yam ntxwv thiab kev ua haujlwm ntawm peb cov khoom no txawv kiag li, thiab lawv cov nqi ntxiv kuj txawv heev.
Lub hnub ci photovoltaic iav siv dav tshaj plaws niaj hnub no yog iav siab transmittance iav, uas yog iav nrog cov ntsiab lus hlau tsawg, uas feem ntau hu ua ultra-dawb iav. Hlau yog ib qho impurity hauv cov iav zoo tib yam (tshwj tsis yog cov iav kub-absorbing). Lub xub ntiag ntawm hlau impurities, ntawm ib sab, ua rau cov iav xim, ntawm qhov tod tes, ua rau kom cov cua sov nqus ntawm iav, uas txo cov teeb pom kev zoo ntawm iav.
Cov hlau hauv iav yog qhia los ntawm cov khoom siv raw ntawm nws tus kheej, cov ntaub ntawv refractory lossis cov khoom siv hlau, thiab lwm yam, thiab nws tsis tuaj yeem zam nws tag nrho. Ib qho tuaj yeem txo cov ntsiab lus ntawm cov hlau hauv iav kom ntau li ntau tau los ntawm kev tswj xyuas ntau lawm. Tam sim no, cov ntsiab lus hlau ntawm lub hnub ci iav iav yog nyob nruab nrab ntawm {{0}}}008 feem pua thiab 0.02 feem pua , thaum cov ntsiab lus hlau ntawm cov iav ntab iav yog siab dua 0.7 feem pua. Tsawg hlau cov ntsiab lus impurities tuaj yeem ua rau lub hnub ci xa hluav taws xob siab. Rau feem ntau siv 3.2 hli tuab thiab 4 hli tuab iav nyob rau hauv Tuam Tshoj, lub teeb pom kev zoo ntawm lub hnub ci feem ntau ncav cuag 90 feem pua ~ 92 feem pua.
Raws li ib qho ntawm cov khoom tseem ceeb tshaj plaws ntawm cov khoom siv hluav taws xob hnub ci, lub hnub ci photovoltaic iav xav kom cov iav phaj yuav tsum tau pob tshab. Yog li ntawd, cov ntsiab lus ntawm cov ntsiab lus hlau nyob rau hauv siliceous raw cov ntaub ntawv siv los tsim lub hnub ci iav yog nruj heev, thiab cov ntsiab lus ntawm Fe2O3 feem ntau yog 140-150ppm.
Kev siv cov iav photovoltaic. Raws li cov lus ceeb toom, thawj lub teb chaws nyob hauv lub ntiaj teb siv pob tshab iav tiaj tus ua lub substrate los tsim thiab siv lub hnub ci hlwb yog lub teb chaws Yelemees. Cov kws tshawb fawb German tau teeb tsa lub phaj zoo li lub hnub ci cell ua lub qhov rais iav ntawm cov tsev. Nws tuaj yeem muab cov hluav taws xob hluav taws xob ncaj qha los ntawm cov tsev neeg, thiab cov hluav taws xob ntau dhau tuaj yeem muab tso rau hauv daim phiaj hluav taws xob. Kev txhim kho thiab kev siv lub iav thawj zaug no rau lub hnub ci hlwb, uas tsis ntev los no tau muaj nuj nqis los ntawm Tebchaws Meskas thiab Nyij Pooj thiab lwm lub tebchaws, yog li ua kom nrawm nrawm ntawm kev tshawb fawb, kev tsim kho thiab kev siv cov iav uas tsis muaj hlau thiab ultra-thin rau hnub ci zog.
