Kev saib xyuas ntawm photovoltaic modules yog qhov kev lees paub ncaj qha tshaj plaws rau kev tsim hluav taws xob thiab txo qis hluav taws xob.Tom qab ntawd lub hom phiaj ntawm kev ua haujlwm photovoltaic thiab kev saib xyuas cov neeg ua haujlwm yog kawm paub txog kev paub txog photovoltaic modules.
Ua ntej tshaj plaws, cia kuv qhia koj txog kev tsim hluav taws xob photovoltaic thiab vim li cas peb thiaj li tsim lub zog hluav taws xob photovoltaic.Tuam Tshoj txoj kev lag luam ib puag ncig tam sim no thiab kev txhim kho kev lag luam, kev loj hlob loj thiab tsis muaj kev tswj hwm thiab kev siv cov fossil fuels, tsis tsuas yog ua kom cov khoom muaj txiaj ntsig zoo, tab sis kuj ua rau muaj teeb meem loj zuj zus ntxiv.Kev puas tsuaj ib puag ncig.
Tuam Tshoj yog lub ntiaj teb cov chaw tsim khoom thiab cov neeg siv khoom loj tshaj plaws, thiab ze li ntawm 76% ntawm nws lub zog yog muab los ntawm cov thee.Qhov kev cia siab dhau ntawm cov fossil fuel zog qauv tau ua rau muaj kev cuam tshuam zoo rau ib puag ncig, kev lag luam thiab kev sib raug zoo.Ib qho loj ntawm cov thee mining, kev thauj mus los thiab hlawv tau ua rau peb lub teb chaws ib puag ncig puas tsuaj loj.Yog li ntawd, peb nquag txhim kho kev siv lub zog tauj dua tshiab xws li hnub ci zog.Qhov no yog ib qho kev xaiv uas tsis muaj kev zam rau peb lub teb chaws txoj kev ruaj ntseg hluav taws xob thiab kev txhim kho kom ruaj khov.
Photovoltaic zog tsim system muaj pes tsawg leeg
Lub tshuab hluav taws xob photovoltaic feem ntau muaj xws li photovoltaic module array, lub thawv sib txuas, lub inverter, ib theem hloov, lub txee hloov, thiab tom qab ntawd ib qho system uas tseem tsis tau hloov, thiab thaum kawg tuaj rau hauv daim phiaj hluav taws xob los ntawm cov kab.Yog li dab tsi yog lub hauv paus ntsiab lus ntawm kev tsim hluav taws xob photovoltaic?
Kev tsim hluav taws xob photovoltaic feem ntau yog vim cov nyhuv photoelectric ntawm semiconductors.Thaum lub photon irradiates ib tug hlau, tag nrho nws lub zog yuav absorbed los ntawm ib tug electron nyob rau hauv cov hlau.Lub zog absorbed los ntawm electron yog loj txaus los kov yeej lub gravitational quab yuam nyob rau hauv cov hlau thiab ua hauj lwm, tawm hauv cov hlau nto thiab khiav los ua ib tug Optoelectronics, silicon atoms muaj 4 txheej electrons.Yog hais tias phosphorus atoms, uas yog atomic phosphorus atoms nrog 5 txheej electrons, yog doped rau hauv silicon ntshiab, ib tug n-hom semiconductor yog tsim.
Yog hais tias atoms nrog peb txheej electrons, xws li boron atoms, yog tov rau hauv ntshiab silicon los ua ib tug p-type semiconductor, thaum lub p-type thiab n-hom tau ua ke ua ke, qhov chaw sib cuag yuav tsim ib lub cell sib txawv thiab ua ib lub hnub ci. cell.
Photovoltaic modules
Lub photovoltaic module yog qhov tsawg tshaj plaws ntawm lub hnub ci kev sib txuas ua ke nrog lub chaw nruab nrab thiab kev sib txuas sab hauv uas tuaj yeem muab DC tso zis ib leeg.Nws tseem hu ua lub hnub ci vaj huam sib luag.Lub photovoltaic module yog lub hauv paus tseem ceeb ntawm tag nrho photovoltaic zog tsim system.Nws txoj haujlwm yog siv cov nyhuv photoacoustic hluav taws xob rau hnub ci zog hloov mus rau DC lub zog tso zis.Thaum lub hnub ci ci rau ntawm lub hnub ci, lub roj teeb absorbs hluav taws xob los tsim cov photoelectron qhov.Nyob rau hauv qhov kev txiav txim ntawm ib qho hluav taws xob teb nyob rau hauv lub roj teeb, lub photogenerated electrons thiab spin yog sib cais, thiab ib tug tsub zuj zuj ntawm tsub nqi ntawm txawv cim tshwm nyob rau hauv ob kawg ntawm lub roj teeb.Thiab tsim cov duab-tsim tsis zoo siab, uas yog qhov peb hu ua cov duab-tsim photovoltaic nyhuv.
Cia kuv qhia koj txog polycrystalline silicon photovoltaic module tsim los ntawm ib lub tuam txhab.Cov qauv no muaj lub zog ua haujlwm ntawm 30.47 volts thiab lub zog siab tshaj plaws ntawm 255 watts.Los ntawm kev nqus lub hnub ci zog, lub hnub ci hluav taws xob hluav taws xob yog ncaj qha lossis ncaj qha hloov mus rau hauv hluav taws xob hluav taws xob los ntawm cov nyhuv photoelectric lossis photochemical nyhuv.Tsim hluav taws xob.
Piv nrog monocrystalline silicon Cheebtsam, polycrystalline silicon Cheebtsam yog yooj yim los tsim, txuag hluav taws xob noj, thiab muaj qis tag nrho cov nqi ntau lawm, tab sis lub photoelectric conversion efficiency kuj tseem tsawg.
Photovoltaic modules tuaj yeem tsim hluav taws xob nyob rau hauv lub hnub ncaj qha.Lawv muaj kev nyab xeeb thiab txhim khu kev qha, tsis muaj suab nrov thiab tsis muaj kuab paug paug, thiab huv huv thiab tsis muaj kuab lom kiag li.
Tom ntej no, peb qhia cov qauv ntawm cov cuab yeej thiab dismantle nws.
Junction Box
Lub thawv photovoltaic hlws ris yog ib qho txuas ntawm lub hnub ci cell array tsim los ntawm lub hnub ci cell modules thiab lub hnub ci them nyiaj tswj ntaus ntawv.Nws tsuas yog txuas cov hluav taws xob hluav taws xob uas tsim los ntawm lub hnub ci hlwb mus rau sab nraud circuits.
Tempered iav
Kev siv cov iav tempered nrog lub teeb pom kev zoo yog qhov tseem ceeb los tiv thaiv lub roj teeb ntawm lub hlwb los ntawm kev puas tsuaj, uas yog sib npaug rau Jian Bai hais tias peb lub xov tooj ntawm tes tempered zaj duab xis plays lub luag haujlwm tiv thaiv.
Encapsulation
Vim tias cov yeeb yaj kiab feem ntau yog siv los khi thiab kho cov iav tempered thiab cov roj teeb, nws muaj cov pob tshab siab, hloov tau yooj yim, super kub tsis kam thiab dej tsis kam.
Lub tin bar feem ntau yog siv los txuas cov roj teeb zoo thiab tsis zoo los tsim cov kab hluav taws xob sib txuas, uas tsim hluav taws xob hluav taws xob thiab coj mus rau lub thawv sib txuas.
Aluminium Alloy Ncej
Lub thav duab ntawm photovoltaic module yog ua los ntawm cov duab plaub aluminium alloy, uas yog lub teeb yuag thiab hnyav.Nws yog tsuas yog siv los tiv thaiv cov txheej crimping thiab ua si ib qho kev sib khi thiab kev txhawb nqa lub luag haujlwm, uas yog lub hauv paus ntawm lub xov tooj ntawm tes.
Polycrystalline Silicon Solar Cells
Polycrystalline silicon solar cells yog cov khoom tseem ceeb ntawm lub module.Lawv lub luag haujlwm tseem ceeb yog ua kom hloov pauv photoelectric thiab tsim kom muaj hluav taws xob ntau.Crystalline silicon solar cells muaj qhov zoo ntawm cov nqi qis thiab kev sib dhos yooj yim.
Rov qab
Lub backsheet yog nyob rau hauv kev sib cuag ncaj qha nrog rau sab nraud ib puag ncig nyob rau sab nraum qab ntawm lub photovoltaic module.Cov khoom ntim photovoltaic feem ntau yog siv los ntim cov khoom, tiv thaiv cov khoom siv raw thiab cov khoom siv, thiab cais cov hnub ci modules los ntawm txoj siv rov qab.Cov khoom no muaj cov khoom zoo xws li kev laus, kev tiv thaiv kev tiv thaiv, dej tsis kam, thiab roj tsis kam.Nta.
Xaus
Lub ntsiab ncej ntawm lub photovoltaic module yog tsim los ntawm photovoltaic tempered iav encapsulated micro-zaj duab xis, hlwb, tin tuav, aluminium alloy thav ntawv, thiab backplane hlws ris thawv los tsim SC plugs thiab lwm yam tseem ceeb Cheebtsam.
Ntawm lawv, cov crystalline silicon hlwb tau sib koom ua ke los txuas ntau lub hlwb rau pem hauv ntej thiab thim rov qab los ua ib qho kev sib txuas, thiab tom qab ntawd raug coj mus rau lub thawv sib txuas los ntawm txoj siv tsheb npav los tsim lub zog hluav taws xob tso zis hluav taws xob module.Thaum lub teeb hnub ci tau teeb tsa rau ntawm qhov chaw ntawm lub module, lub rooj tsavxwm tsim tam sim no los ntawm kev hloov hluav taws xob., cov kev taw qhia ntawm qhov tam sim no ntws los ntawm qhov zoo electrode mus rau qhov tsis zoo electrode.Muaj ib txheej ntawm zaj duab xis ib sab ntawm sab sauv thiab sab hauv ntawm tes uas ua raws li cov nplaum nplaum.Qhov saum npoo yog pob tshab heev thiab cuam tshuam-resistant tempered.Sab nraub qaum ntawm iav yog PPT backsheet uas tau laminated los ntawm cua sov thiab nqus.Vim tias PPT thiab iav yog melted rau hauv lub cell piece thiab adhered rau tag nrho.Aluminium alloy ncej yog siv los kaw lub module ntug nrog silicone.Muaj cov npav npav nyob tom qab ntawm lub xov tooj ntawm tes.Lub roj teeb txhuas lub thawv yog tsau nrog kev kub siab ua haujlwm.Peb nyuam qhuav qhia txog cov khoom siv photovoltaic module los ntawm disassembly.Cov qauv thiab cov qauv kev ua haujlwm.
