Ngā Pūtau Rā Chalcogenide – Ngā Huarahi Hou me ngā Tirohanga o te Reanga Hou o te Hangarau Photovoltaic

I roto i te whanaketanga tonu o te hangarau photovoltaic, ko ngā pūtau rā chalcogenide, hei tohu mō te tuatoru o ngā whakatipuranga o te hangarau photovoltaic, kua noho hei kaupapa matua i roto i te ao rangahau pūtaiao me te ahumahi mō ō rātou painga ahurei me te kaha nui. Nō nā tata nei, kua angitu te rōpū rangahau i arahina e Ahorangi Yuan Mingjian i te Kura Matū o Te Whare Wānanga o Nankai i roto i te rangahau o ngā pūtau rā chalcogenide, ā, kua werohia he kaha hou ki te whanaketanga o tēnei mara.

Ngā painga ahurei o ngā pūtau rā chalcogenide
He momo rauemi te Chalcogenide he hanganga tioata ahurei, he whānuitia ngā whakamahinga i roto i ngā pūtau rā hou me ētahi atu taputapu haurua-ira. Ko te take i nui ai te aro ki ngā pūtau rā chalcogenide nā ēnei painga nui e whai ake nei:

1. Ngāwari me te hototahi:He pai te ngāwari o te rauemi chalcocite, ka taea te whakarite hei pākahiko ngāwari, e whakarato ana i te āheinga o tana tono i roto i ētahi horopaki tono motuhake, pērā i ngā taputapu mau, ngā hua hiko ngāwari me ētahi atu mara, e whakawhānui ana i te whānuitanga o te tono o te hangarau photovoltaic.
2. Te kaha ki te whakarite i te rohe whānui:Ki te whakatauritea ki ngā pūtau rā tuku iho e hangai ana ki te silicon, he mārama ngā painga o ngā pūtau rā chalcogenide i roto i te whakarite i te rohe nui, mā te tukatuka otinga me ētahi atu tikanga whakarite iti te utu, kia tutuki ai te whakaputa pākahiko rohe nui, he mea nui tēnei mō te whakaiti i te utu o te umanga photovoltaic, me te whakatairanga i te tono nui o te hangarau photovoltaic.
3. Te whai huatanga o te tahuritanga ariā teitei:I roto i te ariā, he nui te whai huatanga o te hurihanga photovoltaic o ngā pūtau rā chalcogenide, ā, he rite tonu te whai huatanga o te rohe ariā ki ērā o ngā pūtau rā tuku iho e ahu mai ana i te silicon. I te hohonu haere tonu o te rangahau, kei te pai haere hoki te whai huatanga hurihanga tuturu o ngā pūtau rā chalcogenide, e whakaatu ana i te kaha nui mō te whanaketanga.

Te wero o ngā pūtau rā chalcogenide
Ahakoa ngā painga maha o ngā pūtau rā chalcogenide, i mua i tōna whakamahinga arumoni nui, kei te aro tonu ki ētahi take matua me whakatau, ā, he tino kitea te raruraru pumau:

1. Te kore pumau o te pāmahana teitei:Hei paparanga mimiti mārama o te pākahiko, ka pāngia nuitia te pumau o te rauemi chalcogenide e ngā āhuatanga taiao o waho. I roto i te whakarite i ngā pūtau hiko chalcogenide mahi-teitei, he maha ngā wā ka hiahiatia kia whakawhirinaki ki ngā tāpiringa tote amine waro hei whakau i te āhua ā-tinana me te whakahaere i te tioata. Heoi, he tino ngāwari te pirau o tēnei tāpiringa i ngā pāmahana teitei, ka puta he taurite kore i roto i te hanganga matū o te kiriata calcite, ka tino whakaiti i te pumau o te pākahiko i roto i te mahi pāmahana teitei, kua waiho hei tetahi o ngā arai matua e whakawhāiti ana i tana tono arumoni nui.
2. Kāore i te rawaka te pumau mō te wā roa:Haunga te pumau o te pāmahana tiketike, ka pāngia hoki ngā pūtau rā chalcogenide e te koroheketanga o ngā rauemi, te ngoikore o te māramatanga me ētahi atu āhuatanga e heke ai te mahi, e pā ana hoki ki te whaihua me te pono o ana tono arumoni ki tētahi taumata.

Ngā putanga hou o te rangahau me ngā whakatutukitanga
I te aro atu ki te raruraru o te ngoikore o te pumau o ngā pūtau rā chalcogenide i raro i ngā āhuatanga mahi pāmahana teitei, i ārahi a Ahorangi Yuan Mingjian o te Kura Matū, Te Whare Wānanga o Nankai, i te rōpū rangahau ki te whakahaere i ngā rangahau mahi tahi taumata teitei o te ao, ā, i tutuki i a rātou ngā hua whakamiharo:

1. Te whakawhanake i tētahi rautaki whakarite hou:I honoa e te tīma rangahau ngā matapae ariā, ā, i angitu te whakawhanake i tētahi rautaki whakarite mō te chalcogenide whakarewa me te pumau wera teitei ake. Ka whakaotihia katoatia e tēnei rautaki te raruraru o te kore ōrite o te wāhanga cesium methamidic o ngā kiriata chalcogenide, ā, ka whakapai ake i te pumau o ngā rauemi chalcogenide.
2. Te whakakotahitanga o te tino whai hua me te tino pumau:Kua whakaatuhia e ngā taputapu pūtau rā Chalcogenide i whakaritea mā tēnei rautaki te pai o te hurihanga pūngao o te ao me te pumau i te pāmahana teitei. Ehara i te mea ko tēnei whakatutukitanga anake te whakatakoto i tētahi turanga hangarau pakari mō te whakapai ake i te pumau o ngā pūtau rā chalcogenide, engari ka whakatuwherahia hoki he tirohanga whānui mō te whakatinanatanga me te hokohoko atu o te hangarau photovoltaic.
3. Te whakaputanga me te hiranga o ngā hua:I te ahiahi o te 30 o Hepetema, i whakaputa a Nature i ngā hua rangahau i raro i te taitara "Cesium amidine component of chalcogenide solar cells with high thermal stability". He mea nui tēnei rangahau mō te whakatairanga i te huringa matomato o te hanganga pūngao o te ao, ā, he tohu tēnei i tētahi putanga nui i roto i te whakatupuranga hou o te hangarau photovoltaic.

Ngā tirohanga whanaketanga ā muri ake nei
Nā te whakatutukitanga o tēnei hua rangahau, kua mārama ake te tirohanga mō te whanaketanga o te pūtau hiko pūngao calcite. I tēnei wā, kei te kaha te rōpū rangahau ki te whakatairanga i te rangahau me te whanaketanga o ngā kōwae pūtau hiko pūngao chalcogenide mahi-teitei e rite ana ki ngā hiahia o te ahumahi mā te mahi tahi i waenga i ngā kura me ngā umanga, hei whakatairanga i te whakamahinga mahi o ngā hua rangahau i te wā e taea ai, me te ahumahi o te taunga.

1. Te whakaterenga o te ahumahi:Mā tēnei putanga hou ka tere ake te ahumahi o ngā pūtau rā chalcogenide, e matapaetia ana ka tutuki i tēnei kaupapa te whakaputanga me te tono arumoni nui i roto i ngā tau torutoru e whai ake nei, ā, ka whakarato hoki i ngā otinga pūngao ma, he pai ake, he iti ake te utu mō te mākete pūngao o te ao.
2. Whakawhanuitanga o te tono:Mā te whakapai tonu i te mahi a ngā pūtau hiko pūngao rā, me te whakaiti anō i te utu o ngā pūtau hiko pūngao chalcogenide, ka whānui ake ngā wāhi whakamahi. Haunga ngā tipu hiko photovoltaic tuku iho, he mea nui te whakaputa hiko tohatoha me ētahi atu mara, tae atu ki te whakaurunga o ngā whare, te pūngao pūkoro, te Ipurangi o ngā Mea me ētahi atu mara hou.
3. Whakatairanga i te panonitanga o te hanganga pūngao:Hei hangarau pūngao ma, whakahou ake, mā te whakamahinga whānui o ngā pūtau rā calcite ka āwhina i te whakatairanga i te huringa matomato o te hanganga pūngao o te ao, ka whakaiti i te whakawhirinaki ki te pūngao pūmua tuku iho, ka whakaiti i ngā tukunga waro, ā, ka whai wāhi pai ki te pakanga ki te huringa āhuarangi o te ao.
