Kei te arohia te pūngao o te rā hei pūtake pūngao o te heke mai i roto i te whakatupuranga hua e whai ake nei. Ko te HPBC tētahi o ngā huarahi i roto i te whanaketanga o te hangarau pūtau rā. Ko te painga o ngā pūtau HPBC he hoahoa whakapā-muri me te hangarau whakapā-taha-muri (PERC). Ko tēnei hanganga ka hanga i tētahi whakapā-kore ki te taha muri o te pūtau hei whakaiti i te parepare o mua me te whakapai ake i te mimiti mārama.
Ko te pūtau HPBC, ko te ingoa katoa ko te Hybrid Passivated Back Contact (HPBC), he whakatupuranga hou o te hangarau pūtau rā tino whai hua.
Ngā āhuatanga hanganga: Ngā pūtau HPBC me te kaiwhakaputa kua whakakorehia me te hononga whakapā kua whakakorehia o te mata o muri (PERC) mā te whakamahi i te hoahoa hononga whakamuri, ko te hanganga e hangaia ana i te tuara o te hononga whakapā kua whakakorehia o te pākahiko hei whakaiti i te atarangi o mua, hei whakapai ake i te mimiti mārama. Te pānga whakakorekore: Ka āwhina te paparanga whakakorekore o ngā pūtau HPBC ki te whakaiti i te whakakotahitanga o te mata me te whakanui ake i te ngaohiko ara iahiko tuwhera (Voc) o te pūtau.
Ngā āhuatanga hangarau: Ka whakakotahi te hangarau pūtau HPBC i te hangarau TOPCon me te IBC hei nuku i ngā raina whatunga whakarewa pūtau katoa, e kawenga ana mō te kohikohi me te kawe i ngā kaikawe, ki te taha o muri o te kōwae, ka kore e aukatia te raina whatunga o te taha o mua o te pūtau, ā, ka whakapai ake i te whakamahinga mārama me te pai o te huringa photovoltaic.
Painga Hangarau: Ko ngā āhuatanga o ngā pākahiko HPBC he kaha te mimiti mārama, he pai te hurihanga, he pumau te tuku hiko, he ataahua ngā hua, ā, he pakari, he pono hoki te hangarau.
Horopaki Taupānga: He pai ngā pūtau HPBC mō ngā horopaki PV tohatoha, inā koa ko te BIPV (Hanga Pūnaha Whakaahua Whakakotahi), e taea ai te whakakotahi i te ataahua o ngā kōwae BC me te toi hoahoanga.
Ko te pākahiko TBC (TOPCon Back Contact) ko te ingoa katoa ko te pākahiko whakakotahi hangarau TOPCon me IBC, e mōhiotia ana ko te pākahiko POLO-IBC. Ngā āhuatanga hanganga: Ka whakamahia e te pākahiko TBC te hononga whakapā paparanga waikura kauhanga (TOPCon) ka whakamahia ki te hanganga hononga whakapā o muri. Ka whakamahia e te hoahoa te kounga teitei o te hononga me ngā āhuatanga hononga pai o te hangarau TOPCon.
Te pūmanawa whai hua: He tino kaha te pūmanawa whai hua o ngā pūtau TBC nā ō rātou āhuatanga pai ki te whakakore i ngā matū me te hoahoa whakapā whakamuri. Te tukanga ahumahi: I tēnei wā, kei te wāhanga rangahau taiwhanga te ara hangarau pākahiko TBC, ā, he maha tonu ngā take me whakatau kia pai ai te whakatairanga i te tukanga ahumahi. I te wā poto, he whānui ake te tirohanga whanaketanga o te ara pākahiko TBC, nā te mea kua pakeke ake te ara tukanga TOPCon i te ara tukanga HJT, he iti ake te utu, ā, he hototahi te raina whakaputa TBC ki te raina whakaputa TOPCon.
Pūmanawa Whakamahinga: Ka taea te whakamahi i ngā pūtau TBC ehara i te mea ki te papa silicon tioata momo-N anake, engari ki te papa momo-P anō hoki, he nui te pūmanawa ki te whakapai ake i te pai o te hurihanga hiko whakaahua me te whakaiti i ngā utu.
Ngā pūtau rā HBC (Heterojunction Back Contact) Ko ngā pūtau HBC, arā, ngā pūtau silicon tioata whakapā-muri heterojunction, he whakakotahitanga o te hangarau whakapā-muri heterojunction (HJT) me te hangarau pūtau rā whai hua-teitei cross index (IBC).
Ngā Āhuatanga Hanganga: Ka whakamahia e ngā pūtau HBC te hangarau heterojunction me te hanganga whakamuri-pā. Hei whakatutuki i te kohinga kawe whai hua, ka hangaia e tēnei hanganga he heterojunction ki te taha muri o te pūtau.
Te Pūmanawa Tino Pai: E kiia ana ko ngā pūtau HBC he kaitono kaha mō ngā pūtau rā tino pai nā ō rātou āhuatanga heterojunction me te hoahoa whakapā-muri. Ko ngā pūtau hpbc, tbc, me te hbc e tohu ana i ngā whanaketanga o te hangarau pūtau photovoltaic, me ngā huarahi hangarau rerekē hei whakanui ake i te pai o te tahuritanga photovoltaic o ngā pūtau. Mō te pai o te tahuritanga, he pai ake ngā pūtau TBC me te HBC i te hangarau IBC tawhito. Ka whakakotahi ngā pūtau HBC i ngā āhuatanga passivation mata o ngā pūtau HJT me ngā painga o te parenga kore-whakarewa i te taha o mua o ngā pūtau IBC, ā, he rua ngā painga o ngā iahiko poto-ara iahiko teitei me ngā ngaohiko ara iahiko tuwhera teitei, ā, e tohu ana i te pai o te tahuritanga photovoltaic teitei rawa atu mō ngā pūtau rā silicon tioata.
