Izinto kunye nolwakhiwo lwenqanawa yegrafiti
I-Graphite Boat sisixhobo senkqubo yobushushu obuphezulu, esidla ngokwenziwa ngezinto ze-graphite ezicocekileyo kakhulu kwaye ziphathwe nge-SiC (silicon carbide) okanye umphezulu wokugquma we-TaC (tantalum carbide) ukuphucula ukumelana ne-oxidation yesixhobo siphela, ukumelana nokugqwala kunye nobomi benkonzo.
Kwimveliso yemizi-mveliso,iinqanawa zegrafayithizihlala zisetyenziswa njengezithwali zee-wafers ze-silicon eziqhelekileyo kwimveliso yenkqubo yokugquma. Isakhiwo sineenqanawa ezininzi ezinesithuba esithile. Kukho indawo encinci kakhulu phakathi kweenqanawa ezimbini ezikufutshane, kwaye ii-wafers ze-silicon zibekwe kumacala omabini omnyango ongenanto.
Umgaqo wokusebenza wesikhephe segrafiti
Ngenxa yokuba i-graphite, izinto ezikwisikhephe se-graphite, inomoya oqhuba kakuhle kunye nomoya oqhuba ubushushu, i-AC voltage isetyenziswa phakathi kwezikhephe ezimbini ezikufutshane ukwenza ii-electrode ezilungileyo nezingalunganga. Xa kukho uxinzelelo oluthile lomoya kunye negesi kwigumbi, kuvela umoya ophumayo phakathi kwezikhephe zimbini. Umoya ophumayo unokubola igesi ye-SiH4 kunye ne-NH3 kwindawo, wenze ii-ion ze-Si kunye ne-N, kwaye zidibane zenze iimolekyuli ze-SiNx. Ibekwa phezu komphezulu we-i-silicon waferukufezekisa injongo yokugquma. Njengomthwali wengubo yelanga yokulwa nokukhanya, ulwakhiwo kunye nobukhulu benqanawa yegrafiti buchaphazela ngokuthe ngqo ukusebenza kakuhle kokuguqulwa kunye nokusebenza kakuhle kwemveliso ye-silicon wafer.
Kutheni ukhetha i-VET Energy?
Njengenkokheli yeTshayinaInqanawa yegrafayithi yePECVDumenzi kunye nomthengisi, emva kweminyaka yophando lobuchwephesha kunye nophuhliso, iVET Energy ngoku inezixhobo zemveliso eziphambili ezifana neToyo Tanso, SGL Carbon, Mersen, abayili bobugcisa abavuthiweyo kunye nabasebenzi bemveliso abanamava, kwaye zonke izixhobo zizinto eziluhlaza ezingeniswa kwamanye amazwe.
Okwangoku, iinqanawa zegrafiti eziveliswa yinkampani yethu zineempawu zokusebenza kakuhle kakhulu kunye nolwakhiwo oluchanekileyo. Kwaye isithuba seenqanawa zegrafiti eziyilwe sifanelekile, ukuze i-silicon wafer coating ifane, umgangatho we-silicon wafer uphuculwe kuzo zonke iinkalo, kwaye ukusebenza kakuhle kokuguqulwa kwamandla elanga kuphuculwe kakhulu. Okubaluleke ngakumbi, i-VET Energy inokuyila kwaye ivelise zonke iintlobo zeenqanawa zegrafiti ezifunekayo kwimarike yangoku, kwaye ixhase iimveliso kunye neenkonzo zobugcisa ezenzelwe wena, ezinokuhlangabezana neemfuno zakho ezahlukeneyo zemveliso yeenqanawa zegrafiti zePECVD ezenzelwe wena.
Isikhephe seGraphite sePECVD esicocekileyo kakhulu sePaneli yeSolar
