Ngā Paewhiri Rā HJT: Te Whakaara i te Anamata o te Pūngao Rā
Whakaarohia he ao e taea ai e ngā panera rā te hopu tata ki ngā hihi katoa o te rā, ka huri hei pūngao ma, ka taea te whakahou me te whai huatanga tino pai. Nau mai ki te wā o te Hangarau Heterojunction (HJT), he whanaketanga hou e whakatakoto ana i ngā paerewa hou i roto i te umanga photovoltaic (PV). Me tōna hanganga ahurei me te mahi pai rawa atu, ehara a HJT i te mea he auaha hangarau noa iho engari he tohu tumanako mō tētahi heke mai pumau.
Te Makutu i Muri i te Hangarau HJT
He mea whakamiharo te HJT, he whakarāpopototanga mō te Hangarau Heterojunction, i roto i te ao pūngao o te rā. He rerekē ki ngā panera rā tuku iho e whakawhirinaki ana ki te momo silicon kotahi, ka whakamahia e ngā panera HJT he huinga matatau o ngā paparanga silicon, he mea nui ia paparanga ki te whakamahi i te mana o te rā.
1. Paparanga o Runga: Hiraka Kore-āhua – Te Kaihopu Mārama
Whakaarohia he kiriata angiangi, angiangi o te silicon e hopu ana i te kihi tuatahi o te rā, e tīmata ana i te huringa makutu o te māramatanga hei hiko.
2. Paparanga Waenga: Hiraka Tioata – Te Whare Mana
Kei raro i te paparanga o runga ko te silicon tioata, he mea mimiti mārama pakari, whai hua hoki. Ko tēnei paparanga te ngākau o te panera HJT, te wāhi e hurihia ai te nuinga o te mārama hei pūngao hiko.
3. Paparanga o raro: Te Hiraka Kore-āhua – Te Kaiwhai Whakaahua
I te tātaritanga o te mārama mā roto i ngā paparanga o runga, ka hopukina ngā photon e toe ana e te paparanga o raro o te silicon amorphous. Mā tēnei ka kore e moumou te hihi mārama, ka nui ake te whakaputanga pūngao.
Te Mahi a ngā Paewhiri Rā HJT i tā rātou Makutu
He rite te hoahoa maha-paparanga o ngā panera HJT ki te whakakotahitanga o te mārama me te silicon. Ina pā te rā ki te panera, ka mimiti te paparanga o runga o te silicon amorphous i ētahi o te mārama, ka puta he utu hiko tuatahi. Kātahi ka riro i te paparanga silicon tioata o waenganui, ka huri i te nuinga o te mārama hei pūngao hiko. Hei whakamutunga, ka hopukina e te paparanga silicon amorphous o raro ngā photons e toe ana, ka panaia te whai huatanga o te panera ki ngā taumata hou.
Te Whai Hua: Te Taonga Matua o ngā Paewhiri HJT
Ko ngā panera HJT te rangatira o te ao rā, e whakamanamana ana ki ngā hua pai o te hurihanga e hae ana ki ngā hangarau tuku iho. Ahakoa e whakahaere ana ngā panera PERC i te hua pai o te 20%, ā, e piki ana ngā panera TOPCon ki te 23%, ko ngā panera HJT te mea tino pai me te hua pai o te taha kotahi o te 26-27%. Heoi, ko te mea tino whakamiharo ko te panera HJT mata-rua, e miharo ana ki ngā hua pai neke atu i te 30%. Nā tēnei ka waiho a HJT hei hangarau tino whai hua e whakamārama ana i te umanga PV i tēnei wā.
Ngā Āhuatanga Ahurei o ngā Paewhiri Rā HJT
1. He Ara Māmā ki te Whakaputa
He mahi māmā noa iho te hanga panera HJT, e whā ngā mahi iti iho i te hanga panera rā tuku iho. Ehara i te mea ka tere ake te tukanga hanga anake, engari ka whakaitihia hoki ngā utu.
2. Te Whai Huatanga o te Tahuritanga Kāore i te Whakaōritea
Nā te hanganga silicon maha-paparanga, ka tukuna e ngā panera HJT te mimiti māramatanga me te hurihanga pūngao tino pai, he tino kanapa atu i ngā hangarau PERC me TOPCon.
3. Te Miharo Takirua
He tino pai ngā panera HJT mō ngā whakatakotoranga kanohi-rua, ina mahi tahi ngā taha e rua o te panera. Mā tēnei kanapa taha-rua ka nui ake te putanga pūngao mai i te horahanga mata kotahi, ka whai hua ia inihi.
4. Toa Wera
Ka tupu pai ngā panera HJT i roto i ngā taiao pāmahana teitei, ā, ka mau tonu tō rātou whai huatanga ahakoa ka piki te konukōre. Nā tēnei ka pai mō ngā rohe paki, werawera hoki, ka ngoikore pea ētahi atu panera.
Te Haerenga Mākete a HJT me te Pae o te Ao kei te heke mai
Ahakoa tōna mahi whakamiharo, he iti noa te wāhanga o te mākete e nohoia ana e te hangarau HJT i tēnei wā. E 70% te wāhanga mākete o TOPCon, ko HJT ia e 5% anake te wāhanga. Ko te utu nui ake o ngā panera HJT, mai i te $0.13 ki te $0.20 ia watt, ki te whakaritea ki te $0.10 ia watt mō ngā waeine momo-P me te momo-N, he mea nui. Heoi, he mārama te heke mai mō HJT i te mea kei te haere tonu ngā whanaketanga ki te whakaheke i ngā utu, kia māmā ake ai te uru atu ki tēnei hangarau.
Ka tiaho te heke mai me HJT
Ehara i te mea he taahiraa whakamua noa iho ngā panera rā HJT; he peke nui i roto i te umanga photovoltaic. Nā te ngāwari o te hanga, te pai ake o te mahi, me te pai o te mahi i raro i ngā āhuatanga rerekē, kua rite ngā panera HJT ki te noho hei paerewa koura mō te pūngao rā. I te mea e piki haere ana te awhi o te ao i te pūngao whakahou, kua rite te hangarau HJT ki te ārahi i te tere ki tētahi heke mai kanapa ake, pumau ake.
Nō reira, ā tērā wā ka pā mai te awhi mahana o te rā, kia maumahara ki te waiata puku o ngā panera HJT, e huri ana i taua māramatanga hei pūngao e whakakaha ana i ō tātou oranga. I roto i ia hihi, he kupu whakaari mō tētahi āpōpō matomato ake, ā, kei konei a HJT hei whakatutuki i taua kupu whakaari.
