Iimpawu Eziphezulu Zomzimba Zeenqanawa ZeGraphite zeVET Energy

Ukusebenza kwesikhephe segrafiti kuxhomekeke kwiimpawu zaso. I-VET Energy idibanisa ubunjineli begrafiti obuphambili kunye neengubo ezizimeleyo ukuze inikezele:

1. Uzinzo oluKhethekileyo lobushushu
- Amaqondo obushushu okusebenza kwi-PECVD adla ngokudlula i-1,200°C. Izikhephe zigcina ulwakhiwo lwazo luqinile kwaye zinciphisa ukwanda kobushushu, ziqinisekisa ukulungelelaniswa kwe-wafer rhoqo naphantsi kwemijikelo yokufudumeza/yokupholisa ngokukhawuleza.
- Ubushushu obuphezulu (23 W/m·K) buqinisekisa ukusasazwa kobushushu ngokulinganayo, buthintela iindawo ezishushu ezinokonakalisa ii-wafers.

2. Ukumelana neekhemikhali
- Ayimelani neegesi ezirhabaxa ezifana ne-NH₃ kunye ne-SiH₄, ezixhaphakileyo kwiinkqubo ze-PECVD. Oku kwandisa ubomi besikhephe kwaye kunciphisa iingozi zongcoliseko.

3. Uyilo lokuHamba kweGesi oluLungileyo
- Uyilo lweproprietary luqinisekisa ukuhamba kwegesi ngokulinganayo kuzo zonke ii-wafers, nto leyo ebalulekileyo kubukhulu befilimu kunye nokwakheka kwayo. Oku kuthetha ngokuthe ngqo ukusebenza kakuhle kweeseli zelanga.

4. Ubomi beNkonzo ende
- Iingubo ze-CVD eziphambili (umz., i-silicon carbide okanye i-tantalum carbide) zomeleza ukuqina. Umzekelo, izinto ezifakwe i-TaC ze-VET Energy zimelana namaqondo obushushu angaphezu kwama-2,500°C kwaye zimelana nokugqwala kwesinyithi esinyibilikisiweyo, ubomi obuphindwe kathathu xa kuthelekiswa nezinto eziqhelekileyo.

5. Amandla okwenza ngokwezifiso
- Ubukhulu kunye neengubo ezilungiselelwe ngokukodwa ukuze zihambelane nezixhobo ezithile (umz., ubungakanani be-wafer ukusuka kwi-intshi ezi-4 ukuya kwi-intshi ezili-12) kunye neemfuno zenkqubo, ukuqinisekisa ukuhlanganiswa okungenamthungo kwimigca yemveliso ekhoyo.

Inqanawa yegrafayithingokuchaseneyoisikhephe se-quartz

Ukumelana okugqwesileyo kobushushu obuphezulu

- Iinqanawa zeGraphite zinokumelana nobushushu obuphezulu kakhulu be-1,200°C~2,500°C, kwaye zine-coefficient yokwandiswa kobushushu ephantsi ngaphakathi kolu luhlu (umzekelo, i-coefficient yokwandiswa kobushushu yeemveliso zeVET Energy yi-4.8×10⁻⁶/°C), enokugcina uzinzo lwesakhiwo kunye nokuchaneka kokulungelelaniswa kwe-wafer. Ngokwahlukileyo koko, umda wobushushu ophezulu weenqanawa zequartz uhlala uyi-1,200°C, kwaye ukusetyenziswa kobushushu obuphezulu ixesha elide kunokubangela ukuguquka okanye ukuqhekeka.

Ukuqhuba kakuhle kobushushu kunye nokufana

- Ukuqhuba kobushushu begrafiti (malunga ne-23 W/m·K) kuphezulu kakhulu kune-quartz (malunga ne-1.4 W/m·K), ngoko ke kwiinkqubo ezifana ne-PECVD (i-plasma enhanced chemical vapor deposition), iibhothi zegrafiti zinokufikelela kulwabiwo lobushushu olufanayo, zinciphise umahluko kubukhulu befilimu ye-wafer, kwaye ziphucule umgangatho womaleko we-passivation weeseli zelanga.

Ukumelana okunamandla nokugqwala kweekhemikhali

- Iinqanawa zeGraphite zinokunyamezelana kakhulu neegesi ezirhabaxa ezifana neNH₃ (ammonia) kunye neSiH₄ (silane), kwaye zifanelekile kwiinkqubo ezifuna ukuchatshazelwa rhoqo ziigesi ezisabelayo (ezifana ne-tubular PERC cell coating). Ukongeza, ngokugquma umphezulu nge-silicon carbide (SiC) okanye i-tantalum carbide (TaC), ubomi benkonzo bunokwandiswa ngakumbi (umzekelo, i-VET Energy's TaC coating inokumelana namaqondo obushushu aphezulu angama-2,500°C).

Uqoqosho kunye nobomi obude

- Izikhephe zegrafiti zihlala ixesha elide kwaye zingaphinda zisetyenziswe izihlandlo ezininzi kwimigca yemveliso yemizi-mveliso, kwaye iindleko zokugcinwa ziphantsi kunezo zezikhephe zequartz. Umzekelo, izikhephe zegrafiti ezenziwe ngokwezifiso zeVET Energy zinokuxhasa iimfuno ezinkulu zemveliso yeewafers eziziisentimitha ezi-4 ~ 12 ngoyilo oluphuculweyo, nto leyo enciphisa iindleko zenkqubo ngewafer nganye.
