Kev nce qib hauv kev siv hluav taws xob hnub ci tau coj mus rau kev txhim kho ntawm ntau homhnub ci hlwb, uas yog monocrystalline thiab polycrystalline silicon cells.Thaum ob hom ua haujlwm tib lub hom phiaj, uas yog siv lub hnub ci zog thiab hloov mus rau hauv hluav taws xob, muaj qhov sib txawv ntawm ob.Kev nkag siab txog qhov sib txawv no yog qhov tseem ceeb rau cov tib neeg tab tom nrhiav kev nqis peev hauv lub hnub ci zog lossis nrhiav kev ua kom zoo zog.
Monocrystallinesilicon hnub cihlwb yog undoubtedly lub feem ntau npaum thiab qub tshaj hnub ci tshuab.Lawv yog tsim los ntawm ib tug siv lead ua qauv thiab muaj ib tug uniform, ntshiab tsos.Cov txheej txheem ntau lawm suav nrog kev loj hlob ib leeg siv lead ua los ntawm silicon noob siv lead ua rau hauv cov duab cylindrical hu ua ingot.Tom qab ntawd cov silicon ingots raug txiav rau hauv nyias wafers, uas yog lub hauv paus rau lub hnub ci hlwb.
Polycrystalline siliconhnub ci hlwbNtawm qhov tod tes, yog tsim los ntawm ntau yam silicon crystals.Thaum lub sij hawm tsim khoom, molten silicon yog poured rau hauv square pwm thiab tso cai rau solidify.Raws li qhov tshwm sim, cov silicon tsim ntau cov crystals, muab lub roj teeb tshwj xeeb shard tsos.Piv nrog cov cell monocrystalline, polycrystalline hlwb muaj cov nqi tsim khoom qis dua thiab qis zog noj.
Ib qho ntawm qhov sib txawv tseem ceeb ntawm ob hom ntawmhnub ci hlwbyog lawv efficiency.Monocrystalline siliconhnub ci hlwbFeem ntau muaj kev ua tau zoo dua, txij li 15% mus rau 22%.Qhov no txhais tau tias lawv tuaj yeem hloov pauv ntau dua ntawm hnub ci rau hauv hluav taws xob.Polycrystalline silicon hlwb, ntawm qhov tod tes, muaj kev ua haujlwm ntawm li 13% mus rau 16%.Thaum tseem ua tau zoo, lawv tsis tshua muaj txiaj ntsig vim qhov tawg ntawm silicon crystals.
Lwm qhov txawv yog lawv qhov tsos.Monocrystalline silicon cells muaj cov xim dub zoo ib yam thiab zoo nkauj dua vim lawv cov qauv siv lead ua ib leeg.Polycrystalline hlwb, ntawm qhov tod tes, muaj lub ntsej muag xiav thiab crumbly vim muaj ntau cov crystals hauv.Qhov kev sib txawv ntawm qhov pom no feem ntau yog qhov kev txiav txim siab rau cov tib neeg tab tom nrhiav rau nruab hnub ci vaj huam sib luag ntawm lawv lub tsev lossis kev lag luam.
Tus nqi kuj yog ib qho tseem ceeb uas yuav tau xav txog thaum sib piv ob homhnub ci hlwb.Monocrystalline siliconhnub ci hlwbzoo li yuav kim dua vim cov nqi ntau lawm nrog rau kev loj hlob thiab tsim cov qauv monocrystalline.Polycrystalline hlwb, ntawm qhov tod tes, tsis tshua kim los tsim, ua rau lawv muaj txiaj ntsig zoo rau ntau tus neeg.
Tsis tas li ntawd, kev ua tau zoo thiab tus nqi sib txawv tuaj yeem cuam tshuam tag nrho kev ua haujlwm ntawm lub hnub ci.Monocrystalline silicon cells tuaj yeem tsim lub zog ntau dua ib square meter vim lawv cov kev ua haujlwm siab dua, ua rau lawv xaiv thawj zaug thaum qhov chaw txwv.Polycrystalline hlwb, thaum tsis tshua muaj txiaj ntsig, tseem muab lub zog tsim nyog thiab tsim nyog qhov chaw muaj chaw txaus.
Hauv kev xaus, nkag siab qhov sib txawv ntawm monocrystalline thiab polycrystalline siliconhnub ci hlwbNws yog ib qho tseem ceeb rau cov uas xav txog kev xaiv hnub ci zog.Thaum cov hlwb monocrystalline muaj kev ua haujlwm siab dua thiab zoo nkauj zoo nkauj, lawv kuj tseem kim dua.Hauv qhov sib piv, cov cell polycrystalline muaj qhov kev xaiv zoo dua, tab sis muaj txiaj ntsig me ntsis.Thaum kawg, qhov kev xaiv ntawm ob los txog rau yam xws li qhov chaw muaj, pob nyiaj siv, thiab kev nyiam ntawm tus kheej.
