Nyob rau hauv off-daim phiaj hnub ci, lub hnub ci vaj huam sib luag yog lub luag haujlwm tseem ceeb rau kev hloov pauv photoelectric; cov ntaub ntawv siv ncaj qha cuam tshuam lub zog tsim hluav taws xob, kev pab lub neej, thiab kev ruaj ntseg system. Tam sim no, qis- fais fab hnub ci vaj huam sib luag yog tsim los siv crystalline silicon, muaj ob hom tseem ceeb: monocrystalline silicon thiab polycrystalline silicon. Monocrystalline silicon panels, ua los ntawm siab -purity ib leeg siv lead ua, muaj qhov zoo xws li kev hloov pauv siab, kev ua haujlwm ruaj khov, thiab lub neej ntev. Muaj peev xwm tsim hluav taws xob ntau dua los ntawm tib thaj chaw saum npoo av, lawv tau siv dav hauv kev tawm - kab sib chaws uas xav tau kev ua haujlwm siab. Polycrystalline silicon panels, tsim los ntawm melting ntau silicon nplej ua ke, muaj cov nqi tsim khoom qis dua tab sis me ntsis kev hloov dua siab tshiab dua li monocrystalline panels, ua rau lawv tsim nyog rau nqi -sensitive, me - nplai fais fab mov tshuab.
Tshaj li cov cell photovoltaic lawv tus kheej, cov hnub ci vaj huam sib luag suav nrog ntau yam khoom siv los xyuas kom muaj zog thiab ua haujlwm ntev -. Qhov saum npoo feem ntau yog npog nrog siab - iav tempered transmittance, uas ua rau lub teeb kis tau zoo thaum tiv thaiv lub hlwb los ntawm kev cuam tshuam sab nraud thiab huab cua hnyav. Ib qho EVA (ethylene-vinyl acetate copolymer) zaj duab xis feem ntau yog siv los npog qhov chaw nruab nrab ntawm lub hlwb thiab cov iav, txhim kho lub module sealing thiab huab cua tsis kam. Cov ntaub ntawv rov qab feem ntau muaj UV- thiab tshav kub- cov ntaub ntawv pov thawj uas tiv thaiv kom tsis txhob ya raws, yog li txhim kho lub vaj huam sib luag rwb thaiv tsev thiab lub neej ntev. Cov ntas feem ntau yog ua los ntawm txhuas alloy-lub teeb, muaj zog, thiab corrosion{10}}tiv taus- ua kom yooj yim installation thaum txhawb nqa lub module tag nrho cov qauv kev ruaj ntseg.
Rau me me - teev tawm -daim phiaj hnub ci, kev txiav txim siab xaiv ntawm cov ntaub ntawv vaj huam sib luag tuaj yeem txhawb nqa lub zog tsim hluav taws xob thiab kev ntseeg tau zoo. Nyob rau hauv xyoo tas los no, kev nce qib hauv kev tsim hluav taws xob photovoltaic-xws li kev txais yuav siab -kev ua haujlwm zoo monocrystalline thiab PERC (Passivated Emitter thiab Rear Cell) thev naus laus zis- tau txhim kho qhov kev hloov pauv tau zoo, ua haujlwm ntev, thiab qis dua - lub teeb kev ua tau zoo ntawm cov khoom me me -, muab lub zog ruaj khov thiab muaj zog ntau dua. off- kab hluav taws xob hluav taws xob.
