Imfihlo "yegolide emnyama" emva kweshishini le-photovoltaic semiconductor: umnqweno kunye nokuxhomekeka kwigraphite ye-isostatic.

I-graphite ye-Isostatic yinto ebaluleke kakhulu kwi-photovoltaics kunye ne-semiconductors. Ngokunyuka okukhawulezayo kweenkampani zasekhaya ze-isostatic zegraphite, ukongamela kweenkampani zangaphandle eTshayina kophukile. Ngophando oluqhubekayo oluzimeleyo kunye nophuhliso kunye neenkqubela phambili zetekhnoloji, izalathisi zokusebenza zezinye zeemveliso zethu ezingundoqo ziyalingana okanye zingcono kunezo sikhuphisana namazwe ngamazwe. Nangona kunjalo, ngenxa yeempembelelo ezimbini zokuwa kwamaxabiso ezinto eziphathekayo kunye nokunciphisa iindleko ngabathengi bokugqibela, amaxabiso aqhubekile ukuhla. Okwangoku, inzuzo yeemveliso zasekhaya eziphantsi zingaphantsi kwama-20%. Ngokukhutshwa okuqhubekayo komthamo wemveliso, uxinzelelo olutsha kunye nemingeni ngokuthe ngcembe iziswa kwiinkampani ze-isostatic graphite.

1. Yintoni isostatic graphite?

I-Isostatic graphite ibhekisa kwizinto zegraphite eziveliswe ngokucinezela isostatic. Ngenxa yokuba i-isostatically icinezelwe i-graphite ixinzelelwe ngokufanayo kwaye ngokuthe ngcembe ngoxinzelelo lwe-liquid ngexesha lenkqubo yokubumba, i-graphite eveliswayo ineempawu ezintle. Ukususela ekuzalweni kwayo ngo-1960, i-isostatic graphite ibe yinkokeli phakathi kwezinto ezintsha zegraphite ngenxa yeempawu zayo ezizodwa kunye noluhlu olubanzi lwezicelo.

2. Inkqubo yokuvelisa igraphite ye-Isostatic

Ukuhamba kwenkqubo yemveliso yegraphite ecinezelekileyo ye-isostatically iboniswe kumzobo. Igraphite ye-Isostatic idinga izixhobo eziluhlaza ze-isotropic ngokwesakhiwo. Iimathiriyeli ekrwada kufuneka zicolwe zibe ngumgubo ocolekileyo. Itekhnoloji yokubumba i-Isostatic kufuneka isetyenziswe. Umjikelo wokuqhotsa mde kakhulu. Ukuze kuphunyezwe ukuxinana okujoliswe kuko, kufuneka imijikelo yokuqhotyoshwa okuninzi kunye nokuqhotsa. , ixesha le-graphitization lide kakhulu kunelo legraphite eqhelekileyo.

3. Ukusetyenziswa kwegraphite ye-isostatic

I-graphite ye-Isostatic inoluhlu olubanzi lwezicelo, ngokukodwa kwi-semiconductor kunye ne-photovoltaic fields.

Kwintsimi ye-photovoltaics, i-graphite ecinezelekileyo ye-isostatically isetyenziswa ikakhulu kumacandelo egraphite kwintsimi eshushu ye-graphite kwiziko lokukhula kwe-crystal ye-silicon enye kunye nakwintsimi ye-graphite eshushu kwi-polycrystalline silicon ingot furnaces. Ngokukodwa, i-clamps ye-polycrystalline silicon imveliso ye-silicon, abasasazi begesi kwiziko le-hydrogenation, izinto zokufudumeza, iisilinda ze-insulation kunye nezifudumezi ze-ingot ze-polycrystalline, iibhloko zesikhokelo, kunye neetyhubhu zesikhokelo sokukhula kwekristale enye kunye nobunye ubungakanani obuncinci. amalungu;

Kwintsimi yee-semiconductors, izifudumezi kunye neesilinda zokufakelwa kwesafire ukukhula kwekristale enye kunokusebenzisa igraphite ye-isostatic okanye igraphite ebunjiweyo. Ukongezelela, ezinye izinto ezinjengama-crucibles, i-heaters, i-electrodes, iiplate zokukhusela ukushisa ukushisa, kunye ne-crystals yembewu Malunga neentlobo ze-30 zabaphathi, iziseko ze-crucibles ezijikelezayo, iiplate ezahlukeneyo zeesetyhula, kunye neeplati zokubonisa ukushisa zenziwe nge-graphite ye-isostatically.
