Hnub ci vaj huam sib luagthiab solar cells ua lub luag haujlwm tseem ceeb hauv kev siv lub hnub ci zog.Txawm li cas los xij, ntau tus neeg feem ntau siv cov lus "hnub ci vaj huam sib luag" thiab "lub hnub ci cell" sib hloov yam tsis paub tias lawv tsis yog tib yam.Hauv tsab xov xwm no, peb yuav ua qhov tob tob rau hauv lub ntiaj teb ntawm lub hnub ci zog thiab sib tham txog qhov sib txawv tseem ceeb ntawm lub hnub ci vaj huam sib luag thiab lub hnub ci.
Ua ntej, cia peb nkag siab tias lub hnub ci cell yog dab tsi.Lub hnub ci hlwb, tseem hu ua photovoltaic cells, yog cov khoom siv uas hloov lub hnub ci ncaj qha rau hauv hluav taws xob hluav taws xob.Lawv feem ntau yog ua los ntawm cov khoom siv semiconductor, xws li silicon, uas muaj peev xwm nqus tau photons (lub teeb me me) thiab tso tawm electrons.Cov hluav taws xob tso tawm no tsim hluav taws xob tam sim no, uas tuaj yeem siv rau ntau lub hom phiaj.
Lub hnub ci vaj huam sib luag, ntawm qhov tod tes, muaj ntau lub hnub ci sib txuas.Lawv tau tsim los ntes lub hnub ci thiab hloov mus rau hauv hluav taws xob ntawm qhov loj dua.Thaum lub hnub ci hlwb yog cov khoom siv ntawm lub hnub ci vaj huam sib luag, lub hnub ci vaj huam sib luag yog ua tiav cov chav nyob rau saum lub ru tsev lossis hauv cov nroj tsuag loj hnub ci.
Ib qho ntawm qhov sib txawv tseem ceeb ntawm lub hnub ci vaj huam sib luag thiab lub hnub ci hlwb yog lawv daim ntawv thov.Lub hnub ci hlwb feem ntau yog siv rau hauv cov khoom siv me me xws li lub laij lej, saib, thiab txawm tias lub dav hlau.Vim lawv qhov loj me thiab kev ua haujlwm siab, lawv yog qhov zoo tagnrho rau kev siv hluav taws xob siv hluav taws xob portable.Hnub ci vaj huam sib luag, ntawm qhov tod tes, feem ntau yog siv los tsim hluav taws xob ntawm qhov loj.Lawv yog thawj qhov kev xaiv rau kev siv vaj tse, kev lag luam, thiab kev lag luam.
Lwm qhov sib txawv ntawm lub hnub ci vaj huam sib luag thiab lub hnub ci hlwb yog lawv cov kev ua tau zoo.Hnub ci hlwb zoo li yuav ua tau zoo dua li hnub ci vaj huam sib luag.Qhov no txhais tau hais tias lub hnub ci hlwb tuaj yeem hloov pauv ntau dua ntawm lub hnub ci rau hauv hluav taws xob.Txawm li cas los xij, vim kev nce qib hauv kev siv thev naus laus zis thiab cov txheej txheem tsim khoom, tag nrho kev ua haujlwm ntawm lub hnub ci vaj huam sib luag tau txhim kho sai.
Tsis tas li ntawd, lub hnub ci vaj huam sib luag thiab lub hnub ci hlwb muaj cov kev xav tau sib txawv.Vim lawv qhov me me, lub hnub ci hlwb tuaj yeem yooj yim sib xyaw rau hauv ntau yam khoom lossis qhov chaw.Piv txwv li, lawv tuaj yeem muab tso rau hauv lub tsev qhov rais los yog muab tso rau hauv cov khoom siv hluav taws xob hloov tau yooj yim.Hnub ci vaj huam sib luag, ntawm qhov tod tes, xav tau thaj chaw loj dua, feem ntau yog lub ru tsev lossis chaw qhib.
Nws yog tsim nyog sau cia tias hnub ci vaj huam sib luag tuaj yeem muab faib ua ob hom: monocrystalline silicon thiab polycrystalline silicon.Monocrystalline hnub ci vaj huam sib luag yog tsim los ntawm ib qho qauv siv lead ua, uas ua rau lawv zoo ib yam thiab ua haujlwm zoo dua me ntsis.Polycrystalline hnub ci vaj huam sib luag, ntawm qhov tod tes, yog tsim los ntawm ntau cov qauv siv lead ua, muab lawv cov tsos speckled.Thaum cov vaj huam sib luag polycrystalline tsis tshua muaj txiaj ntsig zoo dua li cov vaj huam sib luag monocrystalline, lawv feem ntau pheej yig dua.
Hauv cov ntsiab lus, thaum lub hnub ci vaj huam sib luag thiab lub hnub ci lub hnub ci yog ob qho tib si tseem ceeb ntawm lub hnub ci, lawv sib txawv ntawm qhov loj, daim ntawv thov, kev ua haujlwm, thiab kev teeb tsa.Kev nkag siab txog qhov sib txawv no tuaj yeem pab tib neeg txiav txim siab paub ntau ntxiv thaum siv lub hnub lub zog ntau.Txawm hais tias nws tab tom teeb tsa koj lub laij lej nrog lub hnub ci lossis teeb tsa lub hnub ci rau ntawm koj lub ru tsev, lub hnub ci zog yog qhov kev daws teeb meem huv thiab ruaj khov rau peb lub zog xav tau.
