Gukoresha Ibidasanzwe-Isi Ibintu kugirango Utsinde Imirasire y'izuba
isoko: ibikoresho bya AZO Imirasire y'izuba ya Perovskite Imirasire y'izuba ya Perovskite ifite ibyiza kurenza ikoranabuhanga ry'izuba.Bafite ubushobozi bwo gukora neza, biremereye, kandi bigura make ugereranije nibindi bitandukanye.Muri selile yizuba ya perovskite, igipimo cya perovskite gishyizwe hagati ya electrode ibonerana imbere na electrode yerekana inyuma ya selile. Ubwikorezi bwa electrode nu mwobo wo gutwara byinjizwa hagati ya cathode na anode, byorohereza gukusanya amafaranga kuri electrode. Hariho ibyiciro bine bya selile yizuba ya perovskite ishingiye kumiterere ya morphologie hamwe nuburyo bukurikirana bwikwirakwizwa ryubwikorezi: planari isanzwe, planari ihindagurika, mesoporous isanzwe, hamwe na mesoporous structure. Nyamara, ibibi byinshi bibaho hamwe nikoranabuhanga.Umucyo, ubushuhe, na ogisijeni birashobora gutera kwangirika kwabyo, iyinjizwa ryayo rirashobora kudahuza, kandi bafite ibibazo bijyanye no kwishyiriraho imishwarara.Perovskite irashobora gukosorwa na electrolytite yamazi, biganisha kubibazo byumutekano. Kugirango bamenye ibikorwa byabo bifatika, bigomba kunozwa muburyo bwo guhindura imbaraga no gukora neza.Nyamara, iterambere rya vuba mu ikoranabuhanga ryatumye imirasire y'izuba ya perovskite ifite ubushobozi bwa 25.5%, bivuze ko itari inyuma cyane ya selile izuba isanzwe ya silicon. Kugirango bigerweho, ibintu bidasanzwe-byisi byashakishijwe kubisabwa muri selile yizuba ya perovskite.Bafite imiterere ya fotofiziki yatsinze ibibazo.Kubikoresha mumirasire y'izuba ya perovskite rero bizamura imitungo yabyo, bituma birushaho kuba byiza mugushira mubikorwa binini kugirango bisubizwe ingufu zisukuye. Nigute Ntibisanzwe Isi Ifasha Perovskite Imirasire y'izuba Hariho ibintu byinshi byingirakamaro ibintu bidasanzwe byisi bifite bishobora gukoreshwa mugutezimbere imikorere yiki gisekuru gishya cyizuba.Ubwa mbere, okiside no kugabanya ubushobozi bwa ion-isi idasanzwe irashobora guhinduka, bikagabanya intego yibikoresho bya okiside no kugabanuka.Byongeye kandi, imiterere ya firime yoroheje irashobora kugengwa no kongeramo ibyo bintu ubihuza na perovskite ndetse no kwishyuza oxyde de transport. Byongeye kandi, imiterere yicyiciro hamwe na optoelectronic imitungo irashobora guhindurwa mugusimbuza kubisimbuza kaseti.Passivation yuzuye irashobora kugerwaho muburyo bwo kuyinjiza mubikoresho bigenewe haba hagati yimbibi zimbuto cyangwa hejuru yibikoresho. Byongeye kandi, fotora ya infragre na ultraviolet irashobora guhindurwa mumucyo igaragara ya perovskite bitewe nuko hariho orbits nyinshi zinzibacyuho zingufu muri ion zidasanzwe-isi. Ibyiza byibi ni bibiri: birinda perovskite kwangizwa numucyo mwinshi kandi ikagura ibikoresho byerekana ibisubizo.Gukoresha ibintu bidasanzwe byubutaka bitezimbere cyane ituze hamwe nubushobozi bwimirasire yizuba ya perovskite. Guhindura Morphologiya ya Filime Ntoya Nkuko byavuzwe haruguru, ibintu bidasanzwe byisi birashobora guhindura morphologie ya firime yoroheje igizwe na okiside yicyuma.Byanditswe neza ko morphologie yumutwaro wogutwara ibintu bigira ingaruka kumyitwarire ya perovskite no guhura kwayo nubwikorezi bwubwikorezi. Kurugero, doping hamwe na ion-yisi idasanzwe irinda kwegeranya nanoparticles ya SnO2 ishobora gutera inenge zubaka, kandi ikanagabanya imiterere ya kristu nini ya NiOx, ikarema urwego rumwe kandi rworoshye rwa kristu.Rero, firime yoroheje yibintu bitagira inenge irashobora kugerwaho hamwe na doping idasanzwe. Byongeye kandi, urwego rwa scafold muri selile ya perovskite ifite imiterere ya mesoporous igira uruhare runini muguhuza hagati ya perovskite no kwishyuza ubwikorezi bwingirabuzimafatizo zuba.Nanoparticles muri izi nyubako irashobora kwerekana inenge ya morfologiya n'imbibi nyinshi. Ibi biganisha ku ngaruka mbi kandi zikomeye zidafite imirasire ya recombination.Kuzuza ibinure nabyo ni ikibazo.Doping hamwe na ion-yisi idasanzwe igenga imikurire ya scafold kandi igabanya inenge, ikora nanostructures ihuza kandi imwe. Mugutanga iterambere ryimiterere ya morovologiya ya perovskite no kwishyuza ubwikorezi, ion zidasanzwe zisi zirashobora kunoza imikorere muri rusange hamwe niterambere ryimirasire yizuba ya perovskite, bigatuma bikenerwa cyane mubucuruzi bunini. Akamaro ka selile yizuba ya perovskite ntishobora gusobanurwa.Bazatanga ubushobozi buhanitse bwo gutanga ingufu kubiciro biri hasi cyane ugereranije na selile izuba rishingiye kumirasire y'izuba kurisoko.Ubushakashatsi bwerekanye ko doping perovskite hamwe na ion zidasanzwe-isi itezimbere imiterere yayo, biganisha ku kunoza imikorere no gutuza.Ibi bivuze ko selile yizuba ya perovskite ifite imikorere inoze ni intambwe imwe yo kuba impamo.
