Tūhurahia ngā mātāpono, ngā āhuatanga, ngā painga me ngā whakamahinga o ngā hangarau pūtau rā TOPCon, HJT, Perovskite, me IBC.
Hangarau TOPCon (Tunnel Oxide Passivated Contact)
Ngā Mātāpono me ngā Āhuatanga:
He hangarau pūtau rā a TOPCon e ahu mai ana i ngā mātāpono kawe whiriwhiri. Ka tāpirihia he paparanga hauhā silicon tino angiangi (1–2 nm) me te paparanga polysilicon kua tāpirihia hei hanga i tētahi hanganga whakapā kua pāngia. Ka whakaitihia te whakakotahitanga mata me te whakakotahitanga whakapā whakarewa. He nui te ngaohiko ara iahiko tuwhera (Voc), he pai ngā tauwehenga whakakī (FF), me te iti o te kiato iahiko whakakotahi (J0) o ngā pūtau TOPCon.
Ngā tono:
He tino pai ngā pūtau TOPCon mō ngā āhuatanga e hiahia ana ki ngā panera rā tino whai hua, pērā i ngā tipu hiko photovoltaic (PV) nui me ngā pūnaha tuanui. Nā te iti o te hekenga o te mahi i roto i ngā taiao pāmahana teitei, he tino pai mō ngā rohe wera ake.
Te Hiranga me ngā Painga:
Me te rohenga whai huatanga ariā o te 28.7%, ko TOPCon tētahi o ngā hangarau pūtau rā tino whai hua. Ka whakarei ake i te whai huatanga mā te whakapai ake i ngā hononga kawe whiriwhiri, ā, ka taea te whakauru pai ki ngā raina whakaputa pūtau silicon tioata o nāianei, ka whakaiti i ngā utu me ngā arai hangarau mō ngā whakapainga ahumahi.
Hangarau HJT (Heterojunction me te Āhua Angiangi ā-roto)
Ngā Mātāpono me ngā Āhuatanga:
Ka whakakotahi te HJT i te silicon tioata me te hangarau kiriata angiangi hei hanga i tētahi hanganga taha-rua ōrite. Ka whakamahia e ia ngā kiriata silicon amorphous ā-roto me ngā kiriata silicon amorphous kua pania ki ngā taha e rua o te anga silicon momo-N, ka hangaia he hononga PN. Mā ngā waikura kawe mārama (TCO) ka āwhina i te kawe hiko.
Ngā tono:
He pai ngā pūtau HJT, he tino whai hua, he iti hoki te pirau i puta mai i te mārama (LID), mō ngā tono mahi teitei pēnei i ngā pūnaha PV tuanui, ngā mahi ahuwhenua, me ngā mahi whakaahua whakauru-whare (BIPV).
Te Hiranga me ngā Painga:
Ka tukuna e te hangarau HJT te pai o te whakaputanga ki runga ake i te 24%, me te kaha ki te neke atu i te 30%. Ko ōna painga ko te ātete ki te LID me te PID (te whakahekenga i puta mai i te pūmanawa), ngā tauwehenga pāmahana iti, te bifaciality teitei, me te mahi pai i te iti o te mārama. Mā ēnei āhuatanga ka nui ake te hua pūngao me ngā painga ōhanga i ngā pūtau PERC tuku iho.
Ngā Pūtau Rā Perovskite
Ngā Mātāpono me ngā Āhuatanga:
Ka whakamahia e ngā pūtau rā perovskite ngā haurua haurua halide waro-kore-waro me te hanganga ABX3 hei rauemi mimiti mārama. He nui ngā tauwehenga mimiti, he roa te horapa o ngā kaikawe, ā, ka taea te whakarerekē i ngā āputa roopu.
Ngā tono:
He maha ngā whakamahinga o ngā pūtau perovskite, ā, ka taea te whakamahi i roto i ngā tipu hiko nui, i te BIPV, me te whakaputa hiko o roto i te wāhi iti te mārama.
Te Hiranga me ngā Painga:
Kua eke ngā pūtau perovskite ki te 25.7% te pai o ngā mahi taiwhanga, ā, kei reira anō ngā wāhi hei whakapai ake. He iti ngā utu rauemi, he iti te pāmahana o te hanga, ā, he tino pai te mahi i roto i ngā taiao iti te mārama, ā, he otinga whai hua tēnei mō ngā hiahia pūngao kanorau.
Hangarau IBC (Whakapā Whakamuri Iwi-matihiko)
Ngā Mātāpono me ngā Āhuatanga:
Ka whakakorea e te IBC ngā irahiko o mua mā te whakanoho i ngā hoapā katoa ki te taha o muri o te pūtau, ka tangohia ngā arai mimiti mārama, ka whakarei ake hoki i te pai o te huringa.
Ngā tono:
He pai ake ngā pūtau IBC i ngā mākete utu nui, pērā i ngā pūnaha tuanui papai me ngā otinga BIPV kua whakauruhia ki te ataahua.
Te Hiranga me ngā Painga:
Mā te hangarau IBC ka taea te whakanui ake i te pai o te mahi me te whakapai ake i te āhua. Ko ōna painga ko te whakaiti i te ātete raupapa, te pai ake o te ātete atarangi, me te tino pai o te huringa pūngao, he mea tino pai mō ngā tono e whakatairanga ana i te pai me te hoahoa.
Whakamutunga
He mea nui te mahi a ia o ēnei hangarau pūtau-rā matatau ki te whakapai ake i te whai huatanga, te whakaiti i ngā utu, me te whakawhānui ake i te whānuitanga o te whakamahinga o ngā photovoltaics. I te pakeketanga me te whānui o ēnei hangarau, ka tino whakarei ake i te mahi a te rā, ka tere ake te whakawhiti ki te pūngao ma, ā, ka aro atu ki ngā wero āhuarangi.
