Ngokuqhubeka nokuqhubela phambili kweenjongo ze-"dual carbon" zaseTshayina, ishishini le-photovoltaic (PV) lifumana ukukhula okungazange kubonwe ngaphambili. Njengenkqubo ephambili yokuphucula ukusebenza kakuhle kweeseli zelanga kunye nokuphucula ukusebenza kwezixhobo, itekhnoloji yokugquma i-vacuum idlala indima ebaluleke ngakumbi kumanqanaba amaninzi okuvelisa i-PV, iqhuba ukuphuculwa kwemizi-mveliso kunye nokuvelisa izinto ezintsha.
Ukwambathisa ngeVacuum: "Inkqubo engabonakaliyo" esemva kwezixhobo zePV
Ukufakwa kwe-vacuum coating kubhekisa kwindlela yokufaka iifilimu ezincinci kumphezulu we-substrate phantsi kweemeko ze-vacuum, kusetyenziswa iindlela zomzimba okanye zeekhemikhali—ngokuyintloko i-PVD (Physical Vapor Deposition) kunye ne-CVD (Chemical Vapor Deposition). Xa kuthelekiswa neenkqubo zemveli ezimanzi, ukufakelwa kwe-vacuum coating kunika ukufana okuphezulu kwefilimu, ukunamathela okuqinileyo, ulawulo oluchanekileyo lobukhulu, kunye nongcoliseko oluncinci, okwenza kube linyathelo elibalulekileyo ekuvelisweni kwezixhobo ze-photovoltaic ezisebenza kakhulu.
Izicelo eziphambili zeVacuum Coating kwiPhotovoltaics
1. Iingubo ezichasene nokuKhanya (AR) zeeseli zeCrystalline Silicon
Ukusebenzisa izinto zokugquma ezingabonisi ukukhanya kumphezulu weeseli ze-silicon ezikristali kubalulekile ukuphucula ukufunxwa kokukhanya. Izinto eziqhelekileyo ezifana ne-silicon nitride (SiNx) zihlala zifakwa kusetyenziswa i-Plasma Enhanced Chemical Vapor Deposition (PECVD), enciphisa ngempumelelo ukulahleka kokubonakaliswa komphezulu kwaye iphucule ukusebenza kakuhle kweeseli.
2. Iifilimu zeTransparent Conductive Oxide (TCO)
Kwiiseli zelanga ezithambileyo, iileya ze-TCO ezifana ne-ITO (Indium Tin Oxide) kunye ne-AZO (Aluminium-doped Zinc Oxide) zisebenza njengee-electrode eziphambili ezibalulekileyo. Ezi zihlala zifakwa nge-magnetron sputtering, inkqubo ye-PVD eqinisekisa ukuhanjiswa okuphezulu, ukumelana okuphantsi, kunye nokuqina okugqwesileyo kokusingqongileyo.
3. Iileya ezibonisa umva kunye nezithintelo
Izakhiwo zephepha elingasemva zihlala ziquka iileya ezibonisa ukukhanya (umz., Ag, Al) kunye neeleya ezithintela ukukhanya (umz., SiOx, Al2O3), ezisetyenziswa rhoqo nge-vacuum coating. Iileya ezibonisa ukukhanya ziphucula ukubamba ukukhanya kwangaphakathi, ngelixa iileya ezithintela ukukhanya ziphucula uzinzo lwexesha elide kunye nokumelana nokufuma kunye noxinzelelo lobushushu.
4. Ukubekwa kwefilimu encinci kwiiseli zelanga zasePerovskite
Iiseli zelanga ze-perovskite ezikhulayo ziquka iileya ezininzi—ezifana neeleya zothutho, iileya zojongano, kunye neengubo zokugquma—nganye ifuna ukubekwa ngokuchanekileyo nangokungachanekanga. Ingubo yokugquma ibonisa amandla amakhulu kweli candelo, ingakumbi ekufezekiseni iifilimu ezifanayo zendawo enkulu ezibalulekileyo ekukhuleni kwezorhwebo.
Iindlela Zoshishino Neemfuno Zezixhobo
Njengoko ubuchwepheshe be-PV buguqukela kwi-heterojunction (HJT) kunye neeseli ze-perovskite/silicon tandem, imfuno yee-stacks zefilimu ezintsonkothileyo kunye nokuzinza okukhulu kwefilimu iyanda ngokukhawuleza. Ngenxa yoko, abavelisi bezixhobo bazisa iinkqubo eziphambili ezibonisa amandla aphezulu, i-automation, kunye nokusebenza kakuhle kwamandla—njengeenkqubo ezinkulu ze-magnetron sputtering kunye neenkqubo zokugquma i-roll-to-roll vacuum—ukuze kuhlangatyezwane neemfuno zemveliso enkulu yemigca yokuvelisa i-PV yesikali se-GW.
Itekhnoloji yokugquma inika amandla ikamva lelanga
Ukugquma nge-vacuum akusiyondlela eqinisekisiweyo yokuphucula ukusebenza kwemodyuli ye-photovoltaic kuphela kodwa kukwayindlela esisiseko yokuxhasa izakhiwo zeseli ezisebenzayo kakhulu zesizukulwana esilandelayo. Ukusuka kwi-silicon yesiqhelo yekristale ukuya kwizisombululo ezintsha ze-perovskite, ukusuka ekusetyenzisweni kakuhle kwezinto ukuya ekudityanisweni kwenkqubo epheleleyo, itekhnoloji yokugquma idityaniswa kakhulu neshishini lelanga—ivula indlela eya kwikamva lamandla anekhabhoni ephantsi, eluhlaza, kunye nokusebenza kakuhle.
