Kev txo qis ntawm cov peev txheej hluav taws xob yuam kom peb nrhiav cov peev txheej tshiab. Hauv cov xwm txheej zoo li no, qhov kev daws teeb meem zoo tshaj plaws yog siv lub zog tauj dua tshiab ntawm lub hnub. Ib qho cuab yeej siv los hloov lub teeb lub zog rau hauv lub zog hluav taws xob yog hu ua roj teeb hnub ci. Ntau ntxiv, cov neeg uas mob siab txog kev txuag nyiaj yog xav txog kev txhim kho lub hnub ci vaj huam sib luag hauv lawv lub tsev. Nyob rau hauv tsab xov xwm, peb yuav nkag siab txog cov hom ntawm cov roj teeb, lawv qhov zoo thiab qhov tsis zoo, thiab tseem qhia rau koj seb cov duab zoo li cas rau koj lub tsev.
thaj chaw thov
roj teeb hnub ci tau pom daim ntawv thov hauv ntau qhov chaw ntawm tib neeg lub neej. Lawv siv nyob rau hauv chaw nres tsheb thiab hauv kev tsim dav hlau. Hauv Fab Kis, txoj kev loj uas siv hnub ci siv hluav taws xob tau tsim ua kom muaj hluav taws xob rau txoj kev teeb pom kev zoo ntawm ib lub zos me me. Nyob rau hauv lub Mediterranean lub teb chaws, xws li roj teeb yog ntsia rau ntawm lub ru tsev ntawm lub tsev.kom tau raws li qhov xav tau ntawm cov dej kub. Lawv yog siv nyob rau hauv tsheb fais thiab txoj kev teeb. Lub hnub ci teeb pom kev zoo yog nrov nyob rau hauv kev tsim kho kom zoo nkauj illumination ntawm lub tsev, sculptures, cov chaw ua si thiab cov chaw uas nyob ib sab. Cov khoom siv txawb tau nruab nrog cov khoom siv hluav taws xob zoo li no: teeb nyem, lub laij lej, cov players. Kaus lim qab teb tau tsim lub hnub ci vaj huam sib luag uas tuaj yeem muab tso rau hauv tib neeg daim tawv nqaij kom muaj zog cog qoob loo xws li pacemaker.
Qhov zoo thiab qhov tsis zoo
Qhov txiaj ntsig tseem ceeb ntawm cov hnub ci vaj huam sib luag yog kev siv lub hnub ci huv, rov ua dua tshiab. Photocells tsis ua phem rau ib puag ncig thiab tsis tsim suab nrov. Cov qauv tsim ntawm lub roj teeb yog qhov yooj yim heev, yog li qhov kev tawg yog qhov tsawg. Tsis tas li ntawd, koj tuaj yeem ua kom lub zog ntawm lub cuab yeej los ntawm kev ua kom cov panels. Hnub ci vaj huam sib luag yog ruaj khov, lawv lub neej kev pab cuam yog ntau xyoo lawm. Lawv tsis xav tau kev saib xyuas tshwj xeeb, nws tsuas yog yuav tsum tau so ib ntus los ntawm cov plua plav.
Qhov tsis zoo suav nrog qhov nyuaj ntawm kev sib sau ua ke thiab teeb tsa cov tshuab loj. Portable roj teeb tsis tas yuav hloov kho. Cov roj teeb hnub ci muaj qhov ua haujlwm tsawg, tsuas yog li 20%. Yuav kom ua tau raws li qhov xav tau ntawm hluav taws xob ntawm lub tsev me, nws yog ib qho tsim nyog yuav tsum tau teeb tsa cov roj teeb hla ib cheeb tsam loj. Tus nqi ntawm cov hnub ci vaj huam sib luag tseem siab. Qhov no yog vim peculiarities ntawm lawv ntau lawm.
Txoj Cai Ua Haujlwm
Ntau tshajSilicon crystals yog cov khoom siv rau kev tsim cov hnub ci hauv tsev. Silicon wafers yog ib qho semiconductor uas hloov lub teeb lub zog ntawm lub hnub mus rau hauv hluav taws xob hluav taws xob. Nws accumulates nyob rau hauv lub roj teeb. Hnub ci vaj huam sib luag tsim hluav taws xob ncaj qha. Nws yog tsim rau kev siv hluav taws xob LEDs. Yog hais tias lub zog ntawm lub hnub yog siv los ua cov khoom siv hluav taws xob hauv tsev, cov qauv tsim yuav tsum tau ntxiv nrog lub inverter DC-rau-AC inverter. Lub hnub ci module yog them nrog tempered iav los tiv thaiv nws ntawm atmospheric agents thiab plua plav.

Silicon solar cells tuaj nyob rau hauv peb hom: monocrystalline, polycrystalline thiab amorphous.
Monocrystal panels yog tsim los ntawm high-purity silicon nyob rau hauv tus ntawm ib tug kub ntawm 1400 degrees Celsius. Yog li ntawd, ib tug siv lead ua lub cheeb ntawm 14-20 cm thiab ib tug ntev txog li 2 meters yog tau. Cov siv lead ua yog txiav rau hauv daim hlau nrog lub thickness ntawm 250-300 microns thiab muab tso rau ntawm ib daim phiaj ntawm electrodes. Kev ua tau zoo ntawm cov vaj huam sib luag no nce mus txog 19%, cov qauv hauv tsev khav theeb 14-18%. Vim lub complex ntau lawm technology, monocrystalline solar panels yog kim tshaj polycrystalline solar panels. Tsis tas li ntawd, silicon siv lead ua yog polygon, uas yog vim li cas nws yuav tsis muaj peev xwm ua kom tiav tag nrho cov txiaj ntsig ntawm qhov module. Cov xim ntawm ib qho crystals yog dub lossis xiav tsaus.
Polycrystalline hnub ci vaj huam sib luag yog tsim los siv cov cuab yeej yooj yim ntawm qhov kub thiab txias. Semiconductor crystals muaj ntau cov lus qhia, uas txo cov efficiency rau12-14%. Tsis tas li ntawd, lub neej kev pab cuam ntawm cov roj teeb polycrystalline yog 25 xyoo, uas yog ib nrab ntawm cov muaju. Cov polycrystals yog ci xiav thiab tag nrho cov hnub ci module. Qhov kom zoo dua ntawm polycrystalline hnub ci hlwb dhau ib qho muaju yog lub peev xwm nqus cov teeb tawg. Yog li ntawd, kev sib sau ntawm lub zog yog nqa tawm txawm nyob rau hauv huab cua huab cua thiab thaum tsaus ntuj.
Amorphous hnub ci vaj huam sib luag yog tsim los ntawm silicon hydrogen siv cov cuab yeej ua yeeb yaj kiab. Kev ua tau zoo ntawm cov modules yog qhov tsawg heev, txog 5%. Txawm li cas los xij, lawv nqus cov teeb pom kev zoo 20 npaug zoo dua li lwm hom roj teeb. Feem ntau muaj kev sib txuas ntawm amorphous silicon nrog poly- lossis ib qho muaju. Qhov no tso cai rau koj los ua ke qhov zoo ntawm ntau hom semiconductors.
Yuav xaiv li cas?
Yog li xaiv dab tsi rau, polycrystalline lossis monocrystalline solar cells?
Koj yuav tsum tau xyuam xim rau qhov tseeb tias lub zog xav tau tuaj yeem tau txais los ntawm txhua hom roj teeb. Cov lus nug yog nyob rau hauv cheeb tsam muaj rau lawv installation. Yog tias tsis muaj chaw txaus, nws yog qhov zoo dua los nres ntawm ib leeg-crystal modules nrog kev ua haujlwm siab tshaj plaws. Yog tias qhov teeb meem ntawm cheeb tsam tsis tseem ceeb, polycrystalline solar panels rau lub tsev yuav yog qhov kev daws teeb meem zoo tshaj plaws. Nrog lub zog sib npaug, thiab muab cov polycrystals raug nqi li 10% tsawg dua, tag nrho cov nqi ntawm lub hnub ci ua liaj ua teb yuav pheej yig dua me ntsis. Tsis tas li ntawd, polycrystalline solar panels nqus lub zog txawm tias huab cua huab cua.
Qhov teeb meem ntawm fossil zog depletionyog aggravated txhua txhua xyoo, thiab cov degree ntawm ib puag ncig muaj kuab paug yuav mob heev. Hauv qhov no, ntau tus neeg tau mloog zoo rau lwm qhov chaw siv hluav taws xob. Kev cog lus kev taw qhia yog kom tau txais hluav taws xob los ntawm lub teeb lub zog ntawm lub hnub. Hnub ci vaj huam sib luag yog siv los hloov lub teeb rau hauv hluav taws xob. Lawv yog cov ruaj, tsis tsim suab nrov, yooj yim rau kev khiav lag luam. Hauv kev tsim cov hnub ci modules, mono- thiab polycrystals ntawm silicon yog siv. Monocrystalline panels muaj txiaj ntsig zoo dua, thaum polycrystalline hnub ci vaj huam sib luag tuaj yeem nqus cov teeb pom kev tsis zoo thiab pheej yig dua.
