Cabanga ngezwe lapho amaphaneli elanga ehlangana khona ophahleni, ebamba yonke imisebe yokukhanya kwelanga ngempumelelo engakaze ibonwe. Lokhu akulona iphupho elikude kodwa iqiniso elikhulayo ngenxa yamaseli elanga e-BC. Okufushane ngokuthi Buyela Emuva Xhumana namaseli elanga, ubuchwepheshe be-BC buguqula imboni yelanga ngomklamo wayo omusha kanye nokusebenza kwayo okuphezulu. Ake sihlole izimangaliso zamaseli elanga e-BC kanye nekusasa lawo elithembisayo.
Umklamo Ohlakaniphile Wamaseli Elanga e-BC
Amaseli elanga e-BC, noma amaseli elanga e-Back Contact, ayisibonelo sokuqamba okusha endaweni yamandla elanga. Cabanga ngalokhu: zonke izixhumanisi zensimbi kanye namaphuzu okuhlangana avame ukugcwala ubuso bangaphambili beseli lelanga ashukunyiswa ngemuva. Lokhu kuklanywa kabusha okuhle kakhulu kususa imigqa yegridi engathandeki evimba ukukhanya kwelanga, okuvumela iseli ukuthi limunce yonke ingxenye yokukhanya. Umphumela? Iseli lelanga elihle, elisebenzayo elibamba ukukhanya kwelanga okwengeziwe futhi liguqule libe amandla ngempumelelo enkulu.
Ubuchwepheshe be-BC abuyona into entsha kodwa isinyathelo sokuziphendukela kwemvelo esakhela phezu kobuchwepheshe obukhona. Ngokuboleka izici ezinhle kakhulu kubanduleli bazo nokuzihlanganisa zibe uhlobo olusha noluthuthukisiwe, amaseli elanga e-BC athola ukuthuthukiswa kokusebenza kahle okumangalisayo.
Ukusebenza Kahle Okugqamile Kakhulu
Ukusebenza kahle kuyisici esibalulekile sobuchwepheshe belanga, futhi amaseli elanga e-BC abeka amazinga amasha. Amaphaneli endabuko e-Perc (Passivated Emitter kanye ne-Rear Cell) ayakwazi ukuguqula cishe u-20-22% wokukhanya kwelanga kube ugesi, kuyilapho amaphaneli e-Topcon (Tunnel Oxide Passivated Contact) esunduza leso sibalo cishe ku-23%. Nokho, amaseli elanga e-BC awayisa ezingeni elilandelayo ngokukhiqiza kahle cishe ku-24.5% kanye nokusebenza kahle kokuhlola okukhuphuka phakathi kuka-27-29%. Lokhu kuzuza okungu-2-3% ngaphezu kwamaseli elanga e-N-TOPCon kuyisishintshi, okunikeza igxathu elikhulu kubuchwepheshe belanga.
I-Symphony of Technologies
Okwenza ubuchwepheshe be-BC bukhange ngempela ukuthi busebenza ngezindlela eziningi. Amaseli elanga e-BC angavumelana nezinye ubuchwepheshe ezihamba phambili njenge-Perc, TOPCon, kanye ne-HJT (Heterojunction Technology) ukudala amaseli ahlanganisiwe. Cabanga ngamathuba: i-HPBC (Heterojunction with Back Contact), i-TBC (TOPCon with Back Contact), kanye ne-HBC (Heterojunction Back Contact). Lawa ma-hybrid afana nezinkanyezi zomhlaba welanga, ahlanganisa amandla obuchwepheshe obuningi ukuze athuthukise ukusebenza kahle.
Izithako Eziyingqayizivele Zamaseli Elanga e-BC
1. Ukukhanya Kwelanga Okungavimbelwe
Njengoba imigqa yegridi yensimbi ithuthelwe ngemuva, amaseli elanga e-BC anikeza indawo ehlanzekile, engaqhekekile ebamba ukukhanya kwelanga okwengeziwe futhi iguqule ibe amandla ngokusebenza kahle okukhulu.
Ukuthuthukiswa Kokusebenza Kokuguqula
Ukuguqulwa komklamo kuholela emazingeni aphezulu okuguqulwa, okwenza amaseli elanga e-BC abe namandla amakhulu emkhakheni wamandla elanga.
2. Ukubukeka Okukhangayo
Ukungabikho kwemigqa yegridi ebheke phambili kunikeza amaphaneli elanga e-BC ukubukeka okuhle nokulinganayo, okwenza abe ukukhetha okukhangayo kokubili ukufakwa kwezindlu kanye nezentengiselwano.
Ukuhlanganiswa Okuhlanganisiwe
Ikhono lokuhlanganisa ubuchwepheshe be-BC nobunye ubuchwepheshe belanga obuhamba phambili liphumela kumaseli ahlanganisiwe akhulisa ukusebenza kahle nokusebenza kahle.
3. Ukuba khona Kwemakethe kanye Nezinzuzo Eziqhakazile
Njengamanje, amaseli elanga e-BC afana namagugu afihliwe emakethe enkulu yelanga, aphethe isabelo esingu-0.2% kuphela uma kuqhathaniswa ne-TOPCon evelele engu-70%. Kodwa ababukeli bemboni abanjengo-LONGI Green Energy babikezela ushintsho olukhulu. I-LONGI ibikezela ukuthi eminyakeni emi-5-6 ezayo, amaseli elanga e-BC azophakama, okungenzeka asuse i-Topcon njengobuchwepheshe belanga obujwayelekile.
4. Ikusasa Liqhakazile Ngamaseli Elanga e-BC
Amaseli elanga e-BC awagcini nje ngokuthuthuka okuqhubekayo; amelela intuthuko enesibindi eya phambili. Ngokunciphisa ukulahlekelwa komthunzi nokukhulisa ukusebenza kahle kokuguqulwa, ubuchwepheshe be-BC buthembisa ukwakha kabusha isimo samandla elanga. Nakuba amaseli e-BC okwamanje enendawo encane emakethe, ukusebenza kwawo kahle kanye nokukhanga kobuhle kuwenza abe abaphikisi abanamandla ngokumelene nobuchwepheshe obukhona njenge-Perc ne-Topcon.
Amandla angempela amaseli e-BC alele ekuzivumelaniseni kwawo nezimo. Ngokuhlangana nezinye ubuchwepheshe, amaseli e-BC angaguquka abe yizikhungo zamandla ezihlanganisiwe, asunduze imingcele yalokho amaseli elanga angakufeza. Njengoba umhlaba uguqukela emandleni avuselelekayo, amaseli elanga e-BC ami ngomumo ukuhola ukushaja, eguqula uphahla lube amajeneretha kagesi amahle futhi asebenzayo.
Ngakho-ke, ngesikhathi esizayo lapho ubheka phezulu elangeni, cabanga ngomlingo ongabonakali wamaseli elanga e-BC asebenza ngokungakhathali ukuze asebenzise amandla awo. Kuyo yonke imisebe yokukhanya kwelanga kukhona isithembiso sekusasa eliqhakazile neliluhlaza, futhi ubuchwepheshe be-BC bulapha ukuze benze leso sithembiso sibe ngokoqobo.
