Ngā Whakaaro Matua mō te Whakamātautau i ngā Pūtau Hiko-Angiangi Hiraka Kore-āhua me ngā Pūwhakatau Hiko-Ra

Ko ngā pūtau rā, e mōhiotia ana ko ngā pūtau photovoltaic, ka huri tika i te hihi o te rā hei pūngao hiko. Ko te ine i te whai huatanga o ngā pūtau rā ko te aromatawai i te kaha o te hihi o te rā e pā mai ana mā te whakamahi i te ine irahiko me te whakatau i te putanga hiko i te pūwāhi mana mōrahi. Heoi, he uaua tēnei tukanga nā te whakawhirinaki o te mahi pūtau ki te whānuitanga o te rā, e rerekē ana i runga i ngā huringa o te wā, te tauwāhi whenua, me ngā āhuatanga o te rangi. Ko ēnei āhuatanga, me ngā hapa whakatikatika i roto i ngā ine irahiko, ka arahi pea ki ngā inenga koretake me te hē.

Hei whakaiti i ēnei raruraru, ka whakamahia e te nuinga o ngā kaihanga ngā pūwhakatauira pūngao rā hei whakamātautau i te whai huatanga o ngā pūtau pūngao rā i roto i ngā taiao whakahaeretia. Ka whakatikatikaina ēnei pūwhakatauira mā te whakamahi i ngā pūtau paerewa e hangai ana ki te tohatoha hihi o te rā i raro i ngā āhuatanga paerewa.

Ngā Mahanga Noa i te Whakamātautau i ngā Pūtau Hiko-Angiangi Silicon Amorphous
Ka whakamahia e ētahi taiwhanga me ngā tari whakamātautau ngā pūtau silicon tioata hei paerewa tohutoro hei aromatawai i ngā pūtau kiriata angiangi silicon kore-āhua. He maha ngā wā ka puta he hapa ine nui i tēnei mahi, ka ara ake ai te ruarua mō te mahi a ngā pūtau silicon kore-āhua.

Ngā Paerewa o te Ao mō te Whakamātautau i ngā Pūtau Rā
Hei whakarite i ngā whakatauritenga ōrite me te pono, ka tautuhia e ngā paerewa whakamātautau o te ao ngā tikanga motuhake mō te aromatawai pūtau rā:
Whānuitanga: AM1.5
Te hihi: 1000 W/m²
Te pāmahana: 25°C
Ko te AM1.5 e pā ana ki te whānuitanga o te hihi o te rā ina whiti te hihi o te rā i roto i te āhuarangi i te koki e rite ana ki te koki kōmata o te 48.2°.

Mō ngā inenga tika, me tutuki ngā whakaritenga matua e rua:
Me hono te urupare ā-ira o te pūtau tohutoro me te pūtau whakamātautau ki roto i tētahi awhe kua tohua, e tutukihia ana tēnei mā te whakamahi i ngā pūtau tohutoro me ngā pūtau whakamātautau i hangaia mai i te rauemi haurua-ā-ira kotahi me ngā tukanga hanga rite.
Me tino ōrite te pūtake mārama i roto i te tauira ki te hanganga hihi o te paerewa AM1.5.
Ngā Whakaaro Motuhake mō ngā Pūtau Hiraka Kore-āhua
He rerekē rawa ngā pūtau silicon amorphous i ngā pūtau silicon tioata i runga i te rauemi me te urupare ā-ira. Anei ngā whakaaro matua mō te whakamātautau tika:

Whakatikatika i te Hiranga:
Whakamahia he pūtau tohutoro silicon amorphous i hangaia mō te whakatikatika i te hihi. Mā te whakamahi i ngā pūtau silicon tioata mō tēnei kaupapa ka kore e whai hua ngā hua nā te kore ōrite o te hihi. Ahakoa he pūtake mārama pai kei te wātea, he uaua tonu te whakarite i ngā hua tika i roto i ngā taiao taiwhanga, i ngā taiao whakaputa rānei.

Kōwhiringa Pūtake Mārama:
Me whakamahi te pūwhakatauira hihi o te rā i tētahi pūtake mārama me te whānuitanga hihi i waenga i te 300 nm me te 800 nm e ōrite ana ki te hihi AM1.5. He maha ngā wā ka whai hihi infrared ngā pūwhakatauira rama xenon noa (800 nm ki te 1100 nm) e rerekē ana i te paerewa, ka puta he rerekētanga nui.

Urupare Āhuarangi:
Ko te urupare hihi o te pūtau rā e pā ana ki te maha o ngā kaikawe utu i hangaia mō ia photon i tētahi roangaru kua whakaritea. Ko te whānuitanga urupare hihi o ngā pūtau silicon amorphous he 400 nm ki te 800 nm, ki te whakaritea ki te 400 nm ki te 1100 nm mō ngā pūtau silicon crystalline. I te whakamātautau i ngā pūtau silicon amorphous mā te whakamahi i ngā simulators kua whakatikatikaina ki ngā paerewa silicon crystalline, ka whai wāhi te hihi infrared-rich (800 nm ki te 1100 nm) ki te ia o ngā pūtau crystalline engari kāore ki ngā pūtau amorphous. Ka hua ake tēnei i te whakaiti nui i te ia me te mahi whānui o te pūtau silicon amorphous.

Hei tāpiri, ko te urupare ā-ira o ngā pūtau silicon amorphous ka pāngia e ngā āhuatanga pēnei i te māramatanga me te ngaohiko, he mea nui kia whakaarohia ēnei taurangi i raro i ngā āhuatanga kore-paerewa.
