Wibande ku mikorere: Tandem izuba rishingiye kuri chalcogenide nibikoresho kama

Gutezimbere imikorere yizuba kugirango tugere kubwigenge buturuka kumasoko yingufu za fosile nibintu byibanze mubushakashatsi bwizuba. Itsinda riyobowe n’umuhanga mu bya fiziki Dr. Felix Lang wo muri kaminuza ya Potsdam, ari kumwe na Prof. Lei Meng na Prof. Yongfang Li bo mu Ishuri Rikuru ry’Ubumenyi ry’Ubushinwa i Beijing, ryahurije hamwe perovskite hamwe n’ibikoresho byangiza umubiri kugira ngo biteze imbere ingirabuzimafatizo y’izuba igera ku rwego rwo hejuru nk'uko byatangajwe mu kinyamakuru cy’ubumenyi cyitwa Nature.

Ubu buryo bukubiyemo guhuza ibikoresho bibiri bitoranya bikurura uburebure burebure kandi burebure - cyane cyane uturere twubururu / icyatsi n umutuku / infrarafarike yibice - bityo bigahindura imikoreshereze yizuba. Ubusanzwe, ibintu bitukura cyane / bitukura bikurura ingirabuzimafatizo zuba byaturutse mubikoresho bisanzwe nka silicon cyangwa CIGS (umuringa indium gallium selenide). Nyamara, ibyo bikoresho mubisanzwe bisaba ubushyuhe bwo hejuru, bikavamo ikirenge gikomeye cya karuboni.

Mu nyandiko iheruka gusohora muri Kamere, Lang na bagenzi be bahujije ikoranabuhanga ry’izuba rifite ibyiringiro bibiri: perovskite hamwe n’izuba ry’izuba, bishobora gutunganywa ku bushyuhe buke kandi bikagira ingaruka za karuboni. Kugera ku ntera ishimishije ya 25.7% hamwe n’ubwo buryo bushya byari umurimo utoroshye, nkuko byagaragajwe na Felix Lang, wasobanuye agira ati: “Iri terambere ryashobotse gusa mu guhuza iterambere ryibanze.” Iterambere ryambere ryabaye synthèse nshya yumutuku / infragre ikurura ingirabuzimafatizo zuba zakozwe na Meng na Li, ibyo bikaba byongerera ubushobozi bwo kwinjirira mu ntera ya infragre. Lang yakomeje asobanura agira ati: "Icyakora, imirasire y'izuba ya tandem yahuye n'imbogamizi bitewe n'urwego rwa perovskite, igahomba igihombo kinini iyo igenewe gukurura cyane cyane ibice by'ubururu n'icyatsi kibisi cy'izuba. Kugira ngo ibyo bishoboke, twashyize mu bikorwa icyerekezo gishya cya passiwasi kuri perovskite, igabanya inenge y'ibikoresho kandi ikazamura imikorere rusange y'akagari."
