Amandla elanga adonsela ukunaka njengomthombo wamandla wesikhathi esizayo esizukulwaneni esilandelayo semikhiqizo. I-HPBC ingenye yezindlela zokuthuthukiswa kobuchwepheshe bamaseli elanga. Amaseli e-HPBC anenzuzo yomklamo wokuxhumana ngemuva ngokubambisana ne-emitter engasebenzi kanye nobuchwepheshe bokuxhumana obungasebenzi ngemuva (i-PERC). Lesi sakhiwo sivame ukudala ukuxhumana okungasebenzi ngemuva kweseli ukunciphisa ukuvikela kwangaphambili nokuthuthukisa ukumuncwa kokukhanya.
Iseli le-HPBC, igama eligcwele elithi Hybrid Passivated Back Contact (HPBC), liyisizukulwane esisha sobuchwepheshe bamaseli elanga obusebenza kahle kakhulu.
Izici zesakhiwo: Amaseli e-HPBC ane-emitter engasebenzi kanye nokuxhumana okungasebenzi okungaphezulu kobuso bangemuva (PERC) kusetshenziswa ukwakheka kokuxhumana kwangemuva, isakhiwo esivame ukwakheka ngemuva kokuxhumana kwebhethri okungasebenzi ukuze kuncishiswe ukufiphala kwangaphambili, kuthuthukiswe ukumuncwa kokukhanya. Umphumela wokudlulisa: Ingqimba yokudlulisa yamaseli e-HPBC isiza ukunciphisa ukuhlangana kobuso nokwandisa i-voltage ye-open-circuit (Voc) yeseli.
Izici zobuchwepheshe: Ubuchwepheshe beseli le-HPBC buhlanganisa ubuchwepheshe be-TOPCon kanye ne-IBC ukuhambisa yonke imigqa yegridi yensimbi yeseli, enesibopho sokuqoqa nokuthutha abathwali, iye ohlangothini olungemuva lwemojuli, okwenza uhlangothi olungaphambili lweseli lungavimbeki emigqeni yegridi, ngaleyo ndlela kuthuthukiswe ukusetshenziswa kokukhanya kanye nokusebenza kahle kokuguqulwa kwe-photovoltaic.
Inzuzo Yobuchwepheshe: Amabhethri e-HPBC abonakala ngokumuncwa kokukhanya okunamandla, ukusebenza kahle kokuguqulwa okuphezulu, ukudluliselwa kwamandla okuzinzile, imikhiqizo emihle, kanye nobuchwepheshe obuvuthiwe nobuthembekile.
Isimo Sokusetshenziswa: Amaseli e-HPBC afaneleka ngokwemvelo ezimweni ze-PV ezisatshalaliswe, ikakhulukazi i-BIPV (Building Integrated Photovoltaic), engahlanganisa ngokugcwele ubuhle bamamojula e-BC nobuciko bezakhiwo.
Ibhethri le-TBC (TOPCon Back Contact) le-TBC, igama eliphelele yibhethri elihlanganisiwe lobuchwepheshe be-TOPCon kanye ne-IBC, elaziwa nangokuthi ibhethri le-POLO-IBC. Izici zesakhiwo: Ibhethri le-TBC lisebenzisa i-tunnel oxide layer passivation contact (TOPCon) futhi liyisebenzise esakhiweni sokuxhumana sangemuva. Umklamo usebenzisa ikhwalithi ephezulu ye-passivation kanye nezici ezinhle zokuxhumana zobuchwepheshe be-TOPCon.
Amandla okusebenza kahle: Amaseli e-TBC anamandla okusebenza kahle kakhulu ngenxa yezakhiwo zawo ezinhle kakhulu zokudlulisa amandla kanye nomklamo wokuxhumana ngemuva. Inqubo yokukhiqiza: Njengamanje, umzila wobuchwepheshe bebhethri le-TBC usesigabeni sokucwaninga ngelebhu, futhi kusenezinkinga eziningi ezidinga ukuxazululwa ukuze kuthuthukiswe inqubo yokukhiqiza. Esikhathini esifushane, umzila webhethri le-TBC unethuba elibanzi lokuthuthukiswa, ngoba umzila wenqubo we-TOPCon uvuthiwe kakhulu kunomzila wenqubo we-HJT, izindleko ziphansi, futhi umugqa wokukhiqiza we-TBC uhambisana kancane nomugqa wokukhiqiza we-TOPCon.
Amandla Okusebenzisa: Amaseli e-TBC angasetshenziswa hhayi kuphela ku-substrate ye-silicon ekristale yohlobo lwe-N, kodwa futhi naku-substrate yohlobo lwe-P, enekhono elikhulu lokuthuthukisa ukusebenza kahle kokuguqulwa kwe-photoelectric nokunciphisa izindleko.
Amaseli elanga e-HBC (Heterojunction Back Contact) Amaseli elanga e-HBC, okungukuthi, amaseli e-silicon acwebezelayo e-heterojunction back contact, ayinhlanganisela yobuchwepheshe bokuxhumana emuva be-heterojunction (HJT) kanye nobuchwepheshe bamaseli elanga obusebenza kahle kakhulu be-cross index (IBC).
Izici zesakhiwo: Amaseli e-HBC asebenzisa ubuchwepheshe be-heterojunction kanye nesakhiwo sokuxhumana ngemuva. Ukuze kufezwe ukuqoqwa okusebenzayo kokuthwala, lesi sakhiwo sivame ukwakha i-heterojunction ngemuva kweseli.
Amandla Okusebenza Kakhulu: Amaseli e-HBC abhekwa njengalungele amaseli elanga asebenza kahle kakhulu ngenxa yezici zawo ezinhle kakhulu ze-heterojunction kanye nomklamo wokuxhumana ngemuva. Amaseli e-hpbc, tbc, kanye ne-hbc wonke amele intuthuko kubuchwepheshe bamaseli e-photovoltaic, ngezindlela ezahlukene zobuchwepheshe zokwandisa ukusebenza kahle kokuguqulwa kwe-photovoltaic kwamaseli. Ngokuphathelene nokusebenza kahle kokuguqulwa, amaseli e-TBC kanye ne-HBC adlula ubuchwepheshe be-IBC bakudala. Amaseli e-HBC ahlanganisa izakhiwo zokudlula phezulu kwamaseli e-HJT nezinzuzo zokuvikela okungenansimbi ohlangothini olungaphambili lwamaseli e-IBC, futhi anezinzuzo ezimbili zamaza aphezulu e-short-circuit kanye nama-voltage aphezulu e-open-circuit, futhi amele ukusebenza kahle kokuguqulwa kwe-photovoltaic okuphezulu kwamaseli elanga e-silicon ekristalini.
