Ngokuqhubeka kwentuthuko yemigomo "ye-dual carbon" yaseShayina, imboni ye-photovoltaic (PV) ikhula ngendlela engakaze ibonwe. Njengenqubo ebalulekile yokuthuthukisa ukusebenza kahle kwamaseli elanga nokuthuthukisa ukusebenza kwedivayisi, ubuchwepheshe bokumboza nge-vacuum budlala indima ebaluleke kakhulu ezigabeni eziningi zokukhiqizwa kwe-PV, okuqhuba ukuthuthukiswa kwezimboni kanye nokusungula izinto ezintsha.
Ukugqoka Nge-Vacuum: "Inqubo Engabonakali" Engemuva Kwamadivayisi E-PV
Ukufakwa kwe-vacuum kubhekisela enkambisweni yokufaka amafilimu amancane phezu kwendawo engaphansi komhlaba ngaphansi kwezimo ze-vacuum, kusetshenziswa izindlela zomzimba noma zamakhemikhali—ikakhulukazi i-PVD (Physical Vapor Deposition) kanye ne-CVD (Chemical Vapor Deposition). Uma kuqhathaniswa nezinqubo zendabuko ezimanzi, ukufakwa kwe-vacuum kunikeza ukufana okuphezulu kwefilimu, ukunamathela okuqinile, ukulawulwa kobukhulu obuqondile, kanye nokungcola okuncane, okwenza kube yisinyathelo esibalulekile ekukhiqizweni kwamadivayisi e-photovoltaic asebenza kahle kakhulu.
Izicelo Eziyinhloko Zokumboza Nge-Vacuum ku-Photovoltaics
1. Izimbozo Ezingabonisi Ukugqama (AR) Zamaseli E-Crystalline Silicon
Ukusebenzisa izembozo ezingabonisi ukukhanya ebusweni bamaseli e-silicon acwebezelayo kubalulekile ukuthuthukisa ukumuncwa kokukhanya. Izinto ezivamile ezifana ne-silicon nitride (SiNx) zivame ukufakwa kusetshenziswa i-Plasma Enhanced Chemical Vapor Deposition (PECVD), enciphisa ngempumelelo ukulahlekelwa kokukhanya kokukhanya futhi ithuthukise ukusebenza kahle kwamaseli.
2. Amafilimu e-Transparent Conductive Oxide (TCO)
Kumaseli elanga anombala omncane, izendlalelo ze-TCO ezifana ne-ITO (Indium Tin Oxide) kanye ne-AZO (i-Aluminium-doped Zinc Oxide) zisebenza njengama-electrode angaphambili abalulekile. Lawa avame ukufakwa nge-magnetron sputtering, inqubo ye-PVD eqinisekisa ukudluliselwa okuphezulu, ukumelana okuphansi, kanye nokuqina okuhle kwemvelo.
3. Izendlalelo Zokubuka Emuva Nezithiyo
Izakhiwo ze-backsheet zivame ukufaka izendlalelo ezibonisa ukukhanya (isb., Ag, Al) kanye nezendlalelo zezithiyo (isb., SiOx, Al2O3), ezivame ukusetshenziswa nge-vacuum coating. Izendlalelo ezibonisa ukukhanya zithuthukisa ukubamba ukukhanya kwangaphakathi, kuyilapho izendlalelo zezithiyo zithuthukisa ukuzinza kwesikhathi eside kanye nokumelana nomswakama kanye nokucindezeleka kokushisa.
4. Ukususwa Kwefilimu Encane Kumaseli Elanga asePerovskite
Amaseli elanga e-perovskite akhulayo ahlanganisa izendlalelo eziningi—njengezendlalelo zokuthutha, izendlalelo ze-interface, kanye nezembozo ze-encapsulation—nganye edinga ukufakwa okunembile kakhulu, okunomonakalo omncane. I-vacuum coating ibonisa amandla amakhulu kulesi sigaba, ikakhulukazi ekufezeni amafilimu endawo enkulu afanayo abalulekile ekukhuleni kwezentengiselwano.
Izitayela Zemboni Nezidingo Zemishini
Njengoba ubuchwepheshe be-PV buguqukela ku-heterojunction (HJT) kanye namaseli e-perovskite/silicon tandem, isidingo sama-stack amafilimu ayinkimbinkimbi kakhulu kanye nokuqina okukhulu kwefilimu sikhula ngokushesha. Ngenxa yalokho, abakhiqizi bemishini bethula izinhlelo ezithuthukisiwe ezine-throughput ephezulu, ukuzenzekela, kanye nokusebenza kahle kwamandla—njengezinhlelo ezinkulu ze-magnetron sputtering kanye nezinhlelo zokumboza i-vacuum roll-to-roll—ukuze kuhlangatshezwane nezidingo zokukhiqiza ngobuningi zemigqa yokukhiqiza ye-PV yesilinganiso se-GW.
Ubuchwepheshe Bokumboza Bunika Amandla Ikusasa Lelanga
Ukumbozwa kwe-vacuum akuyona nje indlela eqinisekisiwe yokuthuthukisa ukusebenza kwemojula ye-photovoltaic kodwa futhi kuyindlela eyinhloko yokusiza izakhiwo zamaseli ezisebenza kahle kakhulu zesizukulwane esilandelayo. Kusukela ku-silicon evamile yekristalu kuya kuzixazululo ezintsha ze-perovskite, kusukela ekusetshenzisweni kahle kwezinto kuya ekuhlanganisweni kwenqubo egcwele, ubuchwepheshe bokumbozwa buya ngokuya buhlangana kakhulu nemboni yelanga—okuvula indlela eya ekusaseni lamandla anekhabhoni ephansi, eluhlaza, nesebenza kahle kakhulu.
