Solar photovoltaic simba rekugadzira rave indasitiri yesimba nyowani inovimbisa pasi rose. Kuenzaniswa nepolysilicon uye amorphous silicon solar masero, monocrystalline silicon, senge photovoltaic simba rekugadzira zvinhu, ine yakakwira photoelectric shanduko inoshanda uye yakanakisa kutengeserana mabhenefiti, uye yave iyo huru yezuva photovoltaic simba rekugadzira. Czochralski (CZ) ndiyo imwe yenzira huru dzekugadzirira monocrystalline silicon. Kuumbwa kweCzochralski monocrystalline furnace kunosanganisira choto system, vacuum system, gasi system, thermal field system uye magetsi ekudzora system. Iyo thermal field system ndeimwe yeakanyanya kukosha mamiriro ekukura kwemonocrystalline silicon, uye mhando yemonocrystalline silicon inokanganiswa zvakananga nekushisa gradient kugovera kwenzvimbo inopisa.
The thermal field components zvinonyanya kuumbwa nekabhoni zvinhu (graphite materials and carbon/carbon composite materials), izvo zvakakamurwa kuita zvikamu zvinotsigira, zvinoshanda, zvinodziya zvinhu, zvinodzivirira, thermal insulation materials, etc., zvichienderana nemabasa avo, se inoratidzwa muMufananidzo 1. Sezvo ukuru hwemonocrystalline silicon huri kuramba huchiwedzera, hukuru hunodiwa hwezvikamu zvemunda wekupisa huri kuwedzerawo. Carbon/carbon composite zvinhu inova sarudzo yekutanga yezvinopisa munda zvinhu zvemonocrystalline silicon nekuda kwekugadzikana kwayo kwedimensional uye yakanakisa mechaniki zvivakwa.
Mukuita kwe czochralcian monocrystalline silicon, kunyunguduka kwesilicon zvinhu kunoburitsa silicon mhute uye yakanyungudutswa silicon splash, zvichikonzera kunyungudutswa kwekabhoni/carbon thermal munda zvinhu, uye mashandiro emuchina uye hupenyu hwebasa hwekabhoni/carbon thermal munda zvinhu zviri. zvakakomba. Naizvozvo, maitiro ekudzikisa kukukurwa kwesilicification yekabhoni/carbon thermal field materials uye kuvandudza hupenyu hwavo hwesevhisi yave imwe yezvinonyanya kunetsekana nevagadziri vemonocrystalline silicon uye kabhoni/carbon thermal field material vagadziri.Silicon carbide coatingyave sarudzo yekutanga yekudzivirira kwekuvhara kwepamusoro kwekabhoni / kabhoni thermal munda zvinhu nekuda kwekunaka kwayo kwekushisa kwekushomeka uye kuramba kupfeka.
Mupepa iri, kutanga kubva kucarbon/carbon thermal field materials inoshandiswa mukugadzirwa kwesilicon yemonocrystalline, nzira huru dzekugadzirira, zvakanakira nekuipira kwesilicon carbide coating zvinounzwa. Nechikonzero ichi, mashandisirwo uye kufambira mberi kwekutsvagisa kwesilicon carbide coating mucarbon/carbon thermal field materials inoongororwa zvichienderana nehunhu hwekabhoni/carbon thermal field materials, uye mazano nemafambisirwo enzira yekudzivirira kwekuvhara pamusoro pekabhoni/carbon thermal field materials. zvinoiswa mberi.
1 Kugadzirira tekinoroji yesilicon carbide coating
1.1 Embedding nzira
Iyo yekumisikidza nzira inowanzo shandiswa kugadzirira iyo yemukati yekupfeka yesilicon carbide muC / C-sic composite zvinhu system. Iyi nzira inotanga kushandisa hupfu hwakasanganiswa kuputira kabhoni/carbon composite zvinhu, uyezve kuita kupisa kwekupisa pane imwe tembiricha. Mutsara wezvakaoma physico-kemikari maitiro anoitika pakati pehupfu hwakavhenganiswa uye pamusoro peiyo sampuli kuti igadzire kupfekedza. Kubatsira kwaro ndekwekuti nzira yacho iri nyore, nzira imwe chete inogona kugadzirira dense, isina-isina matrix composite zvinhu; Diki saizi shanduko kubva preform kusvika yekupedzisira chigadzirwa; Inokodzera chero fiber yakasimbiswa chimiro; Imwe yekuumbwa gradient inogona kuumbwa pakati pekuputira uye substrate, iyo yakanyatsobatanidzwa neiyo substrate. Zvisinei, panewo zvipingamupinyi, zvakadai semakemikari anoita pakupisa kwepamusoro, izvo zvinogona kukuvadza fiber, uye michina ye carbon / carbon matrix inoderera. Kufanana kwejasi kwakaoma kudzora, nekuda kwezvinhu zvakadai segiravhiti, izvo zvinoita kuti chifukidzo chisaenzana.
1.2 Slurry coating nzira
Slurry coating nzira ndeyekusanganisa iyo yekubikira uye binder mumusanganiswa, yakaenzana bhurasho pamusoro peiyo matrix, mushure mekuoma muinert mhepo, iyo yakavharwa yemuenzaniso inoputirwa pakupisa kwepamusoro, uye iyo inodiwa yekupfeka inogona kuwanikwa. Zvakanakira ndezvokuti nzira yacho iri nyore uye iri nyore kushanda, uye ukobvu hwekuputira huri nyore kudzora; Izvo zvisingabatsiri ndezvokuti kune simba rakashata rekubatanidza pakati pekuputira uye substrate, uye kupisa kwekupisa kwekuputira kwekuputira kwakashata, uye kufanana kwekuputira kwakaderera.
1.3 Chemical vapor reaction nzira
Chemical vapor reaction (CVR) nzira inzira inofefetera yakasimba silicon material musilicon mhute pane imwe tembiricha, uye ipapo mhute yesilicon inopararira ichipinda mukati nepamusoro pematrix, uye inopindira mu situ nekabhoni mumatrix kuti ibudise. silicon carbide. Zvakanakira zvinosanganisira mhepo yakafanana muchoto, inowirirana reaction rate uye deposition ukobvu hwezvinhu zvakavharwa kwese; Maitiro acho ari nyore uye ari nyore kushanda, uye ukobvu hwekuputira hunogona kudzorwa nekushandura iyo silicon vapor pressure, deposition nguva uye mamwe ma parameter. Izvo zvakashata ndezvekuti sampuli inokanganiswa zvakanyanya nechinzvimbo muchoto, uye iyo silicon mhute yekumanikidza muchoto haigone kusvika kune iyo theoretical kufanana, zvichikonzera kusaenzana kwekuputira ukobvu.
1.4 Chemical vapor deposition nzira
Chemical vapor deposition (CVD) inzira iyo mahydrocarbon anoshandiswa segasi sosi uye kuchena kwakanyanya N2/Ar semutakuri gasi kuunza gasi rakasanganiswa mumakemikari vapor reactor, uye mahydrocarbons anoora, anogadzirwa, anoparadzirwa, anoshambadzirwa uye anogadziriswa pasi pe. imwe tembiricha uye kumanikidza kugadzira mafirimu akasimba pamusoro pekabhoni/carbon composite zvinhu. Kubatsira kwaro ndeyokuti kuwanda uye kuchena kwekuputira kunogona kudzorwa; Inokodzerawo kushanda-chidimbu nechimiro chakaoma; Iyo crystal chimiro uye pamusoro morphology yechigadzirwa inogona kudzorwa nekugadzirisa iyo deposition paramita. Izvo zvisingabatsiri ndezvekuti deposition rate yakadzikira, maitiro acho akaomarara, mutengo wekugadzira wakakwira, uye panogona kunge paine hurema hwekupfeka, hwakaita sekutsemuka, mesh kukanganisa uye kuremara kwepasi.
Muchidimbu, nzira yekumisikidza inongogumira kune yayo tekinoroji maitiro, ayo akakodzera kusimudzira nekugadzirwa kwerabhoritari uye diki-saizi zvinhu; Coating nzira haina kukodzera kugadzirwa kwakawanda nekuda kwekusagadzikana kwayo. CVR nzira inogona kusangana nekuwanda kugadzirwa kwezvakakura saizi zvigadzirwa, asi ine zvakakwirira zvinodiwa zvemidziyo uye tekinoroji. CVD nzira inzira yakanaka yekugadziriraSIC coating, asi mutengo wayo wakakwira kupfuura CVR nzira nekuda kwekuomerwa kwayo mukugadzirisa maitiro.
