Polycrystalline silicon thiab monocrystalline silicon yog ob yam khoom sib txawv, polycrystalline silicon yog ib lo lus tshuaj feem ntau hu ua iav, high-purity polycrystalline silicon cov ntaub ntawv yog high-purity iav, monocrystalline silicon yog cov khoom siv raw rau hnub ci photovoltaic hlwb, thiab cov khoom siv rau ua semiconductor chips.Cov khoom siv raw ntawm silicon ore rau kev tsim cov monocrystalline silicon yog qhov tsawg thiab cov txheej txheem ntau lawm yog qhov nyuaj, yog li cov zis qis thiab tus nqi siab.Yog li dab tsi yog qhov txawv ntawm monocrystalline silicon solar cells thiab polycrystalline solar cells, thiab qhov twg zoo dua?
Ua ntej, qhov sib txawv ntawm qhov tsos
Los ntawm cov tsos, plaub fab ntawm monocrystalline silicon cell yog arc-puab thiab tsis muaj qauv ntawm qhov chaw;thaum plaub lub ces kaum ntawm polycrystalline silicon cell yog square thiab saum npoo muaj cov qauv zoo ib yam li cov ice paj;cov uas tsis yog-crystalline silicon cell yog qhov peb feem ntau hais lus ntawm nyias zaj duab xis modules, tsis zoo li crystalline silicon hlwb, cov kab sib chaws tuaj yeem pom, thiab qhov chaw yog qhov tseeb thiab du zoo li daim iav.
Qhov thib ob, siv qhov sib txawv saum toj no
Rau cov neeg siv, tsis muaj qhov sib txawv ntawm cov roj teeb monocrystalline silicon thiab polycrystalline silicon roj teeb, thiab lawv lub neej ntev thiab kev ruaj ntseg zoo heev.Txawm hais tias qhov kev hloov pauv nruab nrab ntawm monocrystalline silicon hlwb yog kwv yees li 1% siab dua li ntawm polycrystalline silicon cells, txij li cov cell monocrystalline silicon tsuas tuaj yeem ua rau hauv quasi-square (plaub sab yog arc-shaped), yuav muaj ib feem ntawm cheeb tsam thaum tsim ib lub hnub ci vaj huam sib luag.Tsis tuaj yeem sau;thiab polysilicon yog square, yog li tsis muaj qhov teeb meem zoo li no, lawv qhov zoo thiab qhov tsis zoo yog raws li hauv qab no:
Crystalline silicon modules: Lub zog ntawm ib qho module yog qhov siab.Nyob rau hauv tib lub hneev taw, lub peev xwm ntsia tau siab dua li ntawm cov duab nyias nyias.Txawm li cas los xij, cov modules hnyav thiab tsis muaj zog, nrog kev ua haujlwm tsis zoo ntawm qhov kub thiab txias, kev ua haujlwm tsis zoo ntawm lub teeb pom kev zoo, thiab qhov kev puas tsuaj ntau xyoo.
Nyias-film modules: Lub zog ntawm ib qho modules kuj qis.Txawm li cas los xij, lub zog tsim kev ua tau zoo yog qhov siab, qhov kub thiab txias ua haujlwm tau zoo, qhov kev ua haujlwm tsis zoo ntawm lub teeb yog qhov zoo, cov duab ntxoov ntxoo shading lub zog poob yog me me, thiab txhua xyoo attenuation tus nqi qis.Kev siv dav hauv ib puag ncig, zoo nkauj thiab ib puag ncig tus phooj ywg.
Thib peb, qhov sib txawv ntawm kev tsim khoom
Lub zog siv hauv kev tsim cov txheej txheem ntawm polycrystalline silicon solar cells yog li 30% tsawg dua li ntawm monocrystalline silicon hnub ci hlwb.Yog li ntawd, polycrystalline silicon hnub ci cell account rau ib feem loj ntawm tag nrho lub ntiaj teb no hnub ci cell tsim, thiab cov nqi tsim kuj tseem qis dua li ntawm monocrystalline silicon hlwb.Yog li ntawd, kev siv ntawm polycrystalline silicon hnub ci hlwb yuav Nws yuav ntau zog-txuag thiab ib puag ncig tus phooj ywg!
Dab tsi yog qhov zoo dua rau monocrystalline silicon lossis polycrystalline silicon solar cells?
Lub photoelectric conversion efficiency ntawm monocrystalline silicon hnub ci hlwb yog hais txog 15%, thiab qhov siab tshaj plaws yog 24%, uas yog lub siab tshaj plaws photoelectric conversion efficiency ntawm tag nrho cov hom ntawm lub hnub ci hlwb tam sim no, tab sis cov nqi ntau lawm yog li ntawd nws yuav tsis tau lug siv. thiab nquag siv.Txij li thaum monocrystalline silicon feem ntau encapsulated los ntawm tempered iav thiab waterproof resin, nws muaj zog thiab ruaj khov, thiab nws cov kev pab cuam lub neej feem ntau mus txog 15 xyoo, mus txog 25 xyoo.
Cov txheej txheem ntau lawm ntawm polycrystalline silicon hnub ci hlwb zoo ib yam li cov monocrystalline silicon hnub ci hlwb, tab sis lub photoelectric conversion efficiency ntawm polycrystalline silicon hnub ci hlwb yog qis dua, thiab photoelectric conversion efficiency yog li 12%.
Hais txog cov nqi tsim khoom, nws yog pheej yig dua li monocrystalline silicon solar cells, cov khoom siv yooj yim rau kev tsim, kev siv hluav taws xob tau txais kev cawmdim, thiab tag nrho cov nqi tsim khoom qis dua, yog li nws tau tsim zoo heev.Tsis tas li ntawd, lub neej kev pab cuam ntawm polycrystalline silicon hnub ci hlwb tseem luv dua li ntawm monocrystalline silicon hnub ci hlwb.Nyob rau hauv cov nqe lus ntawm cov nqi kev ua tau zoo, monocrystalline silicon solar cells yog me ntsis zoo dua.
Cov txheej txheem ntau lawm ntawm polycrystalline silicon hnub ci hlwb zoo ib yam li cov monocrystalline silicon hnub ci hlwb, tab sis lub photoelectric conversion efficiency ntawm polycrystalline silicon hnub ci hlwb yog qis dua, thiab photoelectric conversion efficiency yog li 12%.Hais txog cov nqi tsim khoom, nws yog me ntsis kim dua li monocrystalline silicon hnub ci hlwb, cov khoom siv yooj yim rau kev tsim, kev siv hluav taws xob tau txais kev cawmdim, thiab tag nrho cov nqi tsim khoom qis dua, yog li nws tau tsim zoo heev.Tsis tas li ntawd, lub neej kev pab cuam ntawm polycrystalline silicon hnub ci hlwb tseem luv dua li ntawm monocrystalline silicon hnub ci hlwb.Nyob rau hauv cov nqe lus ntawm cov nqi kev ua tau zoo, monocrystalline silicon solar cells yog me ntsis zoo dua.
Feem ntau hais lus, lub hnub ci hnub ci ntawm kev ua lag luam tseem siv ntau dua ib qho siv lead ua.Yeej, thev naus laus zis yog qhov paub tab, kev ua lag luam loj, thiab kev saib xyuas yooj yim dua.
