Kua riro te whakaputa hiko photovoltaic o te rā hei umanga pūngao hou tino whai hua o te ao. Ki te whakatauritea ki ngā pūtau hiko polysilicon me te silicon amorphous, he nui te pai o te hurihanga photoelectric o te silicon monocrystalline, hei rauemi whakaputa hiko photovoltaic, ā, he tino pai ngā painga arumoni, ā, kua noho hei kaupapa matua mō te whakaputa hiko photovoltaic o te rā. Ko Czochralski (CZ) tētahi o ngā tikanga matua hei whakarite i te silicon monocrystalline. Kei roto i te hanganga o te oumu monocrystalline Czochralski te pūnaha oumu, te pūnaha korehau, te pūnaha hau, te pūnaha mara wera me te pūnaha whakahaere hiko. Ko te pūnaha mara wera tētahi o ngā āhuatanga tino nui mō te tipu o te silicon monocrystalline, ā, ko te kounga o te silicon monocrystalline e pāngia tika ana e te tohatoha pāmahana o te mara wera.
Ko ngā wāhanga o te papa wera he mea hanga nui mai i ngā rauemi waro (ngā rauemi graphite me ngā rauemi hiato waro/waro), e wehea ana ki ngā wāhanga tautoko, ngā wāhanga mahi, ngā huānga whakamahana, ngā wāhanga tiaki, ngā rauemi whakamahana wera, me ētahi atu, e ai ki ā rātou mahi, e whakaaturia ana i te Pikitia 1. I te piki haere tonu o te rahi o te silicon monocrystalline, kei te piki haere hoki ngā whakaritenga rahi mō ngā wāhanga papa wera. Ko ngā rauemi hiato waro/waro te whiringa tuatahi mō ngā rauemi papa wera mō te silicon monocrystalline nā tōna pumau ā-ahu me ōna āhuatanga miihini pai rawa atu.
I roto i te tukanga o te silicon monocrystalline czochralcian, ka puta te kohu silicon i te rewa o te rauemi silicon, ka pakaru te silicon rewa, ka hua ake te memeha o ngā rauemi mara waro/waro, ā, ka tino pāngia ngā āhuatanga hangarau me te roa o te mahi a ngā rauemi mara waro/waro. Nō reira, ko te whakaiti i te memeha o ngā rauemi mara waro/waro me te whakapai ake i tō rātou roa o te mahi kua noho hei tetahi o ngā āwangawanga noa o ngā kaihanga silicon monocrystalline me ngā kaihanga rauemi mara waro/waro.Paninga karawiti siliconkua noho hei whiringa tuatahi mō te tiaki i te paninga mata o ngā rauemi papa waro/waro wera nā te mea he tino ātete ki ngā ru wera me te ātete ki te kakahu.
I roto i tēnei tuhinga, mai i ngā rauemi mara wera waro/waro e whakamahia ana i roto i te hanga silicon monocrystalline, ka whakaurua ngā tikanga whakarite matua, ngā painga me ngā ngoikoretanga o te paninga silicon carbide. I runga i tēnei kaupapa, ka arotakehia te tono me te ahunga whakamua rangahau o te paninga silicon carbide i roto i ngā rauemi mara wera waro/waro e ai ki ngā āhuatanga o ngā rauemi mara wera waro/waro, ā, ka tukuna ngā whakaaro me ngā tohutohu whanaketanga mō te tiakitanga paninga mata o ngā rauemi mara wera waro/waro.
1 Te hangarau whakarite opaninga karawiti silicon
1.1 Tikanga whakauru
Ko te tikanga tāmau he mea whakamahi pinepine hei whakarite i te paninga o roto o te silicon carbide i roto i te pūnaha rauemi hiato C/C-sic. Ka whakamahia tuatahitia e tēnei tikanga te paura whakauru hei takai i te rauemi hiato waro/waro, kātahi ka whakahaerehia he maimoatanga wera i tētahi pāmahana. Ka puta he raupapa o ngā tauhohenga ā-tinana-matū matatini i waenga i te paura whakauru me te mata o te tauira hei hanga i te paninga. Ko tōna painga he māmā te tukanga, kotahi anake te tukanga ka taea te whakarite i ngā rauemi hiato matrix matotoru, kore-ngatata; He iti te huringa rahi mai i te preform ki te hua whakamutunga; He pai mō tētahi hanganga muka kua whakapakarihia; Ka taea te hanga i tētahi rerekētanga hanganga i waenga i te paninga me te papa, ka pai te hono atu ki te papa. Heoi, he ngoikoretanga anō hoki, pērā i te tauhohenga matū i te pāmahana teitei, ka taea te kino i te muka, me te hekenga o ngā āhuatanga miihini o te matrix waro/waro. He uaua ki te whakahaere i te ōritetanga o te paninga, nā ngā āhuatanga pērā i te kaha ā-papa, e kore ai e ōrite te paninga.
1.2 Tikanga paninga paru
Ko te tikanga paninga paru he whakaranu i te rauemi paninga me te mea here ki roto i te ranunga, ka parai kia ōrite ki te mata o te anga, i muri i te maroke i roto i te hau kore mahi, ka whakakoi te tauira pania ki te pāmahana teitei, ā, ka taea te whiwhi i te paninga e hiahiatia ana. Ko ngā painga he māmā te tukanga, he ngāwari hoki te whakahaere, ā, he ngāwari te whakahaere i te matotoru o te paninga; ko te ngoikoretanga he ngoikore te kaha here i waenga i te paninga me te papa, ā, he ngoikore te ātete ki te ru wera o te paninga, ā, he iti te ōrite o te paninga.
1.3 Tikanga tauhohenga kohu matū
Ko te tikanga tauhohenga kohu matū (CVR) he tikanga tukanga e mimiti ana i te rauemi silicon totoka hei kohu silicon i tētahi pāmahana, kātahi ka horapa te kohu silicon ki roto i te mata o roto me te mata o te matrix, ka tauhohe ki te waro i roto i te matrix hei whakaputa i te silicon carbide. Ko ōna painga ko te āhuarangi ōrite i roto i te oumu, te tere tauhohenga ōrite me te matotoru o te rauemi pania ki ngā wāhi katoa; He māmā noa te tukanga, ā, he ngāwari ki te whakahaere, ā, ka taea te whakahaere i te matotoru o te paninga mā te whakarerekē i te pēhanga kohu silicon, te wā whakatakotoranga me ētahi atu tawhā. Ko te ngoikoretanga ko te nui o te pānga o te tauira ki te tūranga i roto i te oumu, ā, kāore e taea e te pēhanga kohu silicon i roto i te oumu te eke ki te ōritetanga ariā, ka hua ake he matotoru paninga koretake.
1.4 Tikanga whakatakoto kohu matū
Ko te whakatakoto kohu matū (CVD) he tukanga e whakamahia ai ngā warowaihā hei pūtake hau me te N2/Ar tino parakore hei hau kawe hei whakauru i ngā hau whakaranu ki roto i te tauhohenga kohu matū, ā, ka wetewetehia, ka hangaia, ka horapa, ka mimitihia, ka whakarewahia ngā warowaihā i raro i tētahi pāmahana me te pēhanga hei hanga kiriata totoka ki runga i te mata o ngā rauemi whakakotahi waro/waro. Ko tōna painga ko te taea te whakahaere i te mātotoru me te parakore o te paninga; He pai hoki mō te wāhanga mahi he āhua uaua ake; Ka taea te whakahaere i te hanganga tioata me te āhua o te mata o te hua mā te whakarerekē i ngā tawhā whakatakoto. Ko ngā ngoikoretanga ko te iti rawa o te tere whakatakoto, he uaua te tukanga, he nui te utu whakaputa, ā, tera pea he hapa paninga, pērā i ngā kapiti, ngā hapa mata me ngā hapa mata.
Hei whakarāpopototanga, ko te tikanga tāmau he mea here ki ōna āhuatanga hangarau, he mea e tika ana mō te whakawhanake me te whakaputa rauemi taiwhanga me ngā rauemi iti; kāore te tikanga paninga e tika ana mō te whakaputa papatipu nā te mea he ngoikore te hanganga. Ka taea e te tikanga CVR te whakatutuki i te whakaputa papatipu o ngā hua rahi, engari he nui ake ngā whakaritenga mō ngā taputapu me te hangarau. Ko te tikanga CVD te tikanga pai mō te whakarite.Paninga SIC, engari he nui ake te utu i te tikanga CVR nā te uaua o te whakahaere tukanga.
