Hnub ci hlwb yog cov khoom siv semiconductor uas ncaj qha hloov hnub ci hluav taws xob rau hauv hluav taws xob hluav taws xob raws li cov nyhuv photovoltaic ntawm semiconductors.Tam sim no kev lag luam hnub ci hlwb feem ntau suav nrog cov hauv qab no: monocrystalline silicon solar cells, polycrystalline silicon solar cells, amorphous silicon solar cells, thiab tam sim no cadmium telluride cells, copper indium selenide cells, nano-titanium oxide sensitized cells, polycrystalline silicon solar cells Thin-fil thiab cov organic solar cells, thiab lwm yam. Crystalline silicon (monocrystalline, polycrystalline) solar cells yuav tsum muaj cov khoom siv zoo purity silicon raw cov ntaub ntawv, feem ntau xav tau purity tsawg kawg yog %, uas yog, qhov siab tshaj ntawm 2 impurity atoms raug tso cai kom muaj nyob hauv 10 lab silicon. atoms.Cov khoom siv silicon yog ua los ntawm silicon dioxide (SiO2, tseem hu ua xuab zeb) ua cov khoom siv raw, uas tuaj yeem yaj thiab cov impurities tshem tawm kom tau cov silicon ntxhib.Los ntawm silicon dioxide rau lub hnub ci hlwb, nws koom nrog ntau cov txheej txheem ntau lawm thiab cov txheej txheem, uas feem ntau roughly faib rau hauv: silicon dioxide-> metallurgical-qib silicon-> high-purity trichlorosilane-> high-purity polysilicon-> monocrystalline silicon pas nrig los yog Polycrystalline silicon. ingot 1 > silicon wafer 1 > solar cell.
Monocrystalline silicon solar cells yog tsim los ntawm monocrystalline silicon.Piv nrog rau lwm hom hnub ci hlwb, monocrystalline silicon cells muaj kev hloov pauv siab tshaj plaws.Nyob rau hauv thaum ntxov hnub, monocrystalline silicon hnub ci hlwb nyob rau feem ntau ntawm cov lag luam qhia, thiab tom qab 1998, lawv rov qab mus rau polycrystalline silicon thiab coj qhov chaw thib ob hauv kev ua lag luam.Vim tias qhov tsis txaus ntawm cov khoom siv polysilicon nyob rau xyoo tas los no, tom qab xyoo 2004, kev lag luam sib koom ntawm monocrystalline silicon tau nce me ntsis, thiab tam sim no feem ntau ntawm cov roj teeb pom hauv khw yog monocrystalline silicon.Lub silicon siv lead ua ntawm monocrystalline silicon hnub ci hlwb yog qhov zoo tshaj plaws, thiab nws cov khoom siv kho qhov muag, hluav taws xob thiab cov khoom siv hluav taws xob zoo sib xws.Cov xim ntawm lub hlwb feem ntau yog xim dub lossis tsaus, uas yog qhov tshwj xeeb tshaj yog rau kev txiav rau hauv cov khoom me me los ua cov khoom siv me me.Conversion Efficiency tau txais nyob rau hauv Laboratory ntawm Monocrystalline Silicon Cells
Nws yog %.Kev hloov dua siab tshiab ntawm kev lag luam zoo tib yam yog 10% -18%.Vim yog cov txheej txheem tsim khoom ntawm monocrystalline silicon hnub ci hlwb, feem ntau cov khoom siv ib nrab ntawm silicon ingots yog cylindrical, thiab tom qab ntawd mus los ntawm kev txiav-> tu -> diffusion junction-> tshem tawm ntawm lub nraub qaum electrode-> ua electrodes-> corroding lub periphery- > evaporation txo.Reflective zaj duab xis thiab lwm yam kev lag luam cores yog ua rau cov khoom tiav.Feem ntau, plaub lub ces kaum ntawm monocrystalline silicon solar cells yog sib npaug.Lub thickness ntawm monocrystalline silicon solar cells feem ntau yog 200uM-350uM tuab.Txoj kev tsim khoom tam sim no yog tsim los ntawm ultra-thin thiab high-efficiency.Cov tuam txhab German hnub ci tau lees paub tias 40uM tuab monocrystalline silicon tuaj yeem ua tiav 20% kev ua haujlwm zoo.Nyob rau hauv zus tau tej cov polycrystalline silicon hnub ci hlwb, lub high-purity silicon raws li cov raw khoom yog tsis purified rau hauv ib tug crystals, tab sis yog melted thiab cam khwb cia rau hauv square silicon ingots, thiab ces ua rau nyias slices thiab zoo xws li ib tug siv lead ua silicon.Polycrystalline silicon yog ib qho yooj yim los txheeb xyuas los ntawm nws qhov chaw.Lub silicon wafer yog tsim los ntawm ntau qhov chaw crystalline ntawm ntau qhov sib txawv (qhov saum npoo yog crystalline).
Oriented grain pawg yog ib qho yooj yim los cuam tshuam nrog photoelectric hloov dua siab tshiab ntawm cov nplej interface, yog li ntawd cov conversion efficiency ntawm polysilicon kuj tsawg.Nyob rau tib lub sijhawm, qhov sib xws ntawm cov khoom siv kho qhov muag, hluav taws xob thiab cov khoom siv hluav taws xob ntawm polysilicon tsis zoo li ntawm monocrystalline silicon hnub ci hlwb.Qhov kev ua tau zoo tshaj plaws ntawm polycrystalline silicon solar cell kuaj yog %, thiab cov khoom lag luam feem ntau yog 10% -16%.Lub polycrystalline silicon hnub ci cell yog ib daim square, uas muaj qhov siab tshaj plaws sau tus nqi thaum ua hnub ci modules, thiab cov khoom kuj zoo nkauj.Lub thickness ntawm polycrystalline silicon hnub ci hnub ci yog feem ntau 220uM-300uM tuab, thiab qee lub tuam txhab tau tsim cov hnub ci hnub ci nrog lub thickness ntawm 180uM, thiab lawv tab tom txhim kho ntawm nyias kom txuag tau cov khoom siv silicon kim.Polycrystalline wafers yog lub kaum sab xis lossis cov duab plaub, thiab plaub fab ntawm ib lub wafers yog chamfered ze rau lub voj voog.
Ib qho uas muaj nyiaj zoo li lub qhov nyob hauv nruab nrab ntawm cov khoom yog ib qho siv lead ua, uas tuaj yeem pom ntawm ib nrais muag.
