He maha ngā take e whakawhirinaki ai ngā mīhini paninga perovskite ki ngā turanga karāhe
Te pumau tino pai
He tino nui ngā whakaritenga mō te tukanga paninga perovskite kia pumau ai ngā taputapu. Ahakoa te wiri iti, te nekehanga rānei, ka taea te arahi ki te matotoru o te paninga kāore i te ōrite, ka pā ki te kounga o ngā kiriata perovskite, ā, ka mutu, ka whakaitihia te pai o te hurihanga hiko o te pākahiko. Ko te mātotoru o te karāneti he 2.7-3.1g/cm³, he mārō te kakano, ā, ka taea te tautoko pumau mō te mīhini paninga. Ki te whakatauritea ki ngā turanga whakarewa, ka taea e ngā turanga karāneti te whakaiti i te pokanoa o ngā wiri o waho, pērā i ngā wiri i puta mai i te whakahaere o ētahi atu taputapu me te nekehanga o ngā kaimahi i roto i te wheketere. I muri i te whakaitihia e te turanga karāneti, he iti noa iho ngā wiri e tukuna ana ki ngā wāhanga matua o te mīhini paninga, e whakarite ana i te ahunga whakamua pumau o te tukanga paninga.
Tino iti te tauwehenga o te whakawhānui wera
Ina whakamahia te mīhini paninga perovskite, ka puta te wera i ētahi wāhanga nā te mahi a te au me te waku miihini, ka piki ake te pāmahana o te taputapu. I taua wā, ka rerekē pea te pāmahana taiao i roto i te awheawhe whakaputa ki tētahi taumata. Ka tino rerekē te rahi o ngā rauemi noa ina rerekē te pāmahana, he mea whakamate tēnei mō ngā tukanga paninga perovskite e hiahia ana ki te tika o te nanoscale. He tino iti te tauwehenga o te whakawhānui wera o te karāhe, tata ki te (4-8) ×10⁻⁶/℃. Ina rerekē te pāmahana, he iti noa te rerekētanga o tōna rahi.
He pai te pumau o te matū
He maha ngā wā ka pāngia ngā otinga matū o te perovskite precursor. I te wā o te tukanga paninga, ki te ngoikore te pumau matū o te rauemi turanga taputapu, ka pāngia pea e te tauhohenga matū me te otinga. Ehara i te mea ka poke noa te otinga, ka pā ki te hanganga matū me te mahi a te kiriata perovskite, engari ka waikura anō hoki te turanga, ka whakapoto i te roa o te mahi a te taputapu. Ko te nuinga o te karāneti he kohuke pēnei i te quartz me te feldspar. He pumau ōna āhuatanga matū, ā, he ātete ki te waikura waikawa me te kawakore. Ina pā atu ki ngā otinga matū precursor perovskite me ētahi atu matū i roto i te tukanga whakaputa, kāore he tauhohenga matū e puta, ka whakarite i te parakore o te taiao paninga me te mahi pumau mō te wā roa o te taputapu.
Ka whakaitihia e ngā āhuatanga whakamākū teitei te pānga o te wiri
I te wā e whakahaerehia ana te mīhini paninga, ka taea e te nekehanga o ngā wāhanga ā-roto o te mīhini te whakaputa wiri, pērā i te nekehanga tauutuutu o te pane paninga me te whakahaere o te motuka. Ki te kore e taea te whakaiti i ēnei wiri i roto i te wā, ka horapa, ka taupatupatu ki roto i te taputapu, ka pā kino atu ki te tika o te paninga. He tino teitei te āhuatanga whakamākū o te karāhe, me te ōwehenga whakamākū i waenga i te 0.05 ki te 0.1, he maha ngā wā he nui ake i ngā rauemi whakarewa.
Te mea ngaro hangarau o te whakatutuki i te papatahi ±1μm i roto i te anga gantry 10-whānui
Hangarau tukatuka tino tika
Hei whakatutuki i te papatahi o te ±1μm mō te anga anga 10-whānui, me whakamahi tuatahi i ngā tikanga tukatuka tino tika i te wāhanga tukatuka. Ka tukatukahia te mata o te anga anga mā te whakamahi i ngā tikanga huri me te whakakanapa tino tika.
Pūnaha kimi me te urupare matatau
;
I roto i te tukanga hanga me te tāutanga o ngā anga gantry, he mea nui kia whakauruhia ki ngā taputapu kimi matatau. Ka taea e te ine whakawhiti laser te ine i te rerekētanga papatahi o ia wāhanga o te anga gantry i te wā tūturu, ā, ka taea e tōna tika ine te eke ki te taumata iti-micron. Ka tukuna ngā raraunga ine ki te pūnaha whakahaere i te wā tūturu. Ka tatau te pūnaha whakahaere i te tūranga me te rahinga e tika ana kia whakatikatikaina i runga i ngā raraunga urupare, kātahi ka whakatikatika i te anga gantry mā te taputapu whakatikatika tino tika.
Hoahoa hanganga kua arotauhia
Mā te hoahoa hanganga whaitake ka āwhina i te whakapakari i te pakari me te pumau o te anga anga, me te whakaiti i te rerekētanga i puta mai i tōna ake taumaha me ngā kawenga o waho. I whakatauirahia, i tātarihia hoki te hanganga o te anga anga anga mā te whakamahi i te pūmanawa tātari huānga mutunga kore hei arotau i te āhua whakawhiti-wāhanga, te rahi me te tikanga hononga o te kurupae whakawhiti me te pou. Hei tauira, ko ngā kurupae whakawhiti me ngā wāhanga whakawhiti āhua-pouaka he kaha ake te ātete ki te hurihuri me te piko ki te whakataurite ki ngā kurupae-I noa, ā, ka taea te whakaiti i te rerekētanga i te whānuitanga 10-mita. I taua wā, ka tāpirihia ngā rara whakapakari ki ngā wāhanga matua hei whakapakari ake i te pakari o te hanganga, kia mau tonu ai te papatahi o te anga anga i roto i te ±1μm ina pāngia e ngā kawenga rerekē i te wā e whakahaerehia ana te mīhini paninga.
Te whiriwhiri me te tukatuka i ngā rauemi
;
Ko te turanga karāhe o te mīhini paninga perovskite, me tōna pumau, te iti o te tauwehenga whakawhanui wera, te pumau matū me ngā āhuatanga whakamākū teitei, e whakarato ana i te turanga pakari mō te paninga tino tika. Kua tutuki i te anga gantry 10-whānui te papatahi tino teitei o te ±1μm mā te raupapa o ngā tikanga hangarau pēnei i ngā tikanga tukatuka tino tika, ngā pūnaha kimi me te urupare matatau, te hoahoa hanganga kua arotauhia, me te kōwhiringa rauemi me te maimoatanga, e whakatairanga tahi ana i te hanga pūtau rā perovskite kia neke atu ki te whai huatanga me te kounga teitei ake.
