He aha ngā tono hou e pā ana ki ngā hua quartz e te wā pūtau momo-N?

Ko ngā whakapainga o te hangarau photovoltaic e akiaki ana i te tipu tonu o te tono mō te quartz parakore-teitei

I te tere haere o te ahumahi photovoltaic (PV) o te ao ki te whakapiki ake i te pai o te mahi, kei te piki haere te rongonui o ngā pūtau momo-N i te mākete. Ko ngā ara hangarau momo-N—pērā i a TOPCon, HJT, me BC—kei te akiaki i tētahi ngaru hou o te whakawhānui i te kaha nā te pai o te pai o te tahuritanga, te iti o ngā reiti pirau, me te pai ake o te mahi whakaputa hiko. I te wā kotahi, ko ngā hua quartz parakore-teitei—ngā mea pau nui i roto i te hanga PV—kei te aro atu ki ngā paerewa teitei ake me ngā whakaritenga hangarau tino pakari ake. E kī ana ngā kaitōrangapū o te umanga kāore i te whakarerekē noa i ngā rerenga mahi hanga ngā whakahoutanga tukanga mō ngā pūtau momo-N, engari i puta mai hoki he wero hou mō te parakore, te ātete wera, me te roa o te mahi o ngā wāhanga quartz matua, pērā i ngā poti quartz, ngā ngongo oumu, ngā ngongo horapa, me ngā ipu pere.

Ko ngā tukanga momo-N e hiahia ana kia teitei ake te parakore i roto i ngā rauemi quartz

Ko ngā wāhanga matua o te hanga TOPCon me HJT—pērā i te horapa i te pāmahana teitei, te waikura, me te whakamahana—e whakawhirinaki nui ana ki ngā hua quartz. Ki te whakatauritea ki ngā pūtau momo-P, he tairongo ake ngā pūtau momo-N ki ngā poke whakarewa. Ka pāngia te kounga o te mata o te anga silicon me te pai o te huringa pūtau e ngā huānga iti pēnei i te rino (Fe), te konumohe (Al), te konutai (Na), me te pāhare pākawa (K) e ngā huānga iti pēnei i te rino (Fe), te konumohe (Al), te konutai (Na), me te pāhare pākawa (K).

Nō reira, ko ngā hua kuata e whakamahia ana i roto i ngā raina whakaputa momo-N me whakamahi i ngā rauemi mata kuata parakore teitei ake hei whakarite:

• He iti ake te ihirangi poke o te konganuku;
• Te parakore matū teitei ake;
• Te whakaiti i te mōrearea o te devitrification (whakatioata);
• He pumau ake te mahi pāmahana teitei.

I tēnei wā, kua whakapiki ake ētahi kaihanga pūtau matua i ā rātou paerewa parakore mō ngā hua kuata ki ngā taumata kōeke-haurua-ira hei whakatutuki i ngā whakaritenga parakore o ngā raina whakaputa matatau.

Ka whakapiki ake ngā tukanga pāmahana teitei i te ātete wera o ngā hua quartz

Ko te pāmahana horapa mō ngā pūtau TOPCon he nui ake i te 800°C, engari ko ētahi wāhanga o te tukanga HJT he nui ake te tono mō te pumau o ngā taputapu.

Mā te roa o te whakamahinga i te pāmahana tiketike ka ara ake pea ngā raruraru pēnei i te rerekētanga o te āhua, te whakakorenga o te vitrification, te hekenga o te tuku māramatanga, te kino o te ru wera, me te poto o te ora mahi.

Nō reira, me whai pumau wera me te ātete ki ngā ru wera te whakatupuranga hou o ngā hua kuata. Mā te arotau i ngā tukanga rewa, te whakahaere i te ihirangi hydroxyl, me te whakapai ake i ngā hanganga rauemi o roto, ka taea e ngā hua kuata te roa ake te ora ratonga i roto i ngā taiao pāmahana teitei, ka āwhina i ngā umanga photovoltaic ki te whakaiti i ngā utu tiaki taputapu me te wā kore mahi.

Ka akiakihia e ngā anga rahi-rahi te auahatanga hanganga i roto i ngā poti quartz

Nā te whānui o te whakamahinga o ngā anga 182mm, 210mm, me ngā anga nunui ake, kua tino whakapiki ake i te uauatanga o te hoahoa poti kuata.

Ko te nekehanga ki ngā rahi wafer nui ake ka whakatakoto i ngā whakaritenga e whai ake nei mō ngā poti quartz:

• Te kaha ā-mīhini teitei ake;
• Te iti rawa o te whakarerekētanga;
• Te whakahaere tika i te mokowā o ngā mokowā;
• Te pumau o te utaina o te wafer.

Ahakoa te iti o te rerekētanga o te poti kuata ka pā ki te mokowā o ngā papa whakarewa me te ōritetanga o te papa wera, ā, ka mutu, ka iti ake te hua.

Nō reira, kei te piki haere te maha o ngā kaiwhakarato hua kuata e whakamahi ana i te miihini CNC tino tika me ngā tukanga tirotiro ā-rahi pakari hei whakarite kia tutuki i ā rātou hua ngā hiahia o te hanga pūtau rā whakatakotoranga nui.

Ko te whakaputa aunoa te take e hiahiatia ai te miihini tika ake

Kei te whanake haere ngā whare hanga hiko photovoltaic ki te hanga atamai me ngā mahi kore tangata.

Ko te whakatinanatanga nui o ngā pūnaha uta/tango aunoa, ngā taputapu whakahaere karetao, me ngā taputapu tirotiro aunoa, ko te tikanga me whai ngā hua kuata i ngā āhuatanga rauemi pai rawa atu engari me whakaatu hoki i te tino tika me te ōrite o ngā āhuatanga.

Ko ngā wāhanga matua ko:

• Te mana whakahaere mō te ātete mokamoka mō ngā poti quartz;
• Te whakahaere i te arotahi mō ngā ngongo oumu quartz;
• Te tika o ngā āhuatanga o ngā hononga flange;
• Te pumau o te kaha o ngā hononga whakarewa.

Ka pā tika ēnei inenga ki te whai huatanga o te whakahaere taputapu me te pumau o ngā raina whakaputa aunoa.

Ka tere ake ngā whai wāhitanga mākete i te whakakapinga ā-rohe

I ngā tau tata nei, ko ngā whanaketanga tonu i roto i te hangarau rauemi kuata parakore o te whare kua arahi ki te pikinga tonu o te wahanga mākete o ngā hua kuata i hangaia i te whare i roto i te rāngai photovoltaic. Nā te whānui haere o te kaha o te hangarau TOPCon, kua piki ake te hiahia mō ngā poti kuata kounga teitei, ngā ngongo oumu, me ngā taonga pau e pā ana, ā, kua hangaia he whai wāhitanga tipu hou mō ngā umanga kuata o te whare. E kī ana ngā matapae ahumahi ka piki tonu te kaha whakaputa pūtau momo-N i ngā tau e haere ake nei, ka waiho hei rauemi tautoko nui mō ngā hua kuata parakore teitei, roa te ora, me te tino tika mō te mekameka tuku photovoltaic. Ko ngā umanga kuata e kaha ana ki te whakapai ake i ā rātou rauemi mata, ngā tukanga, ngā kaha miihini, me ngā paerewa tirotiro, kei te pai te tūnga ki te whiwhi painga whakataetae i te wāhanga e whai ake nei o te whanaketanga ahumahi.

Whakamutunga

Ko te wā o ngā pūtau momo-N ehara i te mea he whakapai ake i te hangarau photovoltaic anake, engari he whakamātautau whānui hoki mō ngā rauemi e tautoko ana i te mekameka tuku o te umanga. Hei taonga whakapau nui i roto i ngā tukanga tohatoha me te maimoatanga wera i te pāmahana teitei, kei te huri ngā hua kuata mai i ngā "rauemi āwhina" ki ngā "rauemi e tika ana mō te mahi." I te anga whakamua, ko te parakore teitei, te tika, me te roa o te ora ratonga ka waiho hei huarahi matua mō te whanaketanga o ngā hua kuata, ka akiaki i te umanga kuata katoa ki tētahi taumata teitei ake o te matatau hangarau.
