Kuvura Vitamine C biteza imbere ingirabuzimafatizo zikomoka ku mirasire y'izuba

Itsinda ry’abashakashatsi bo muri kaminuza y’amajyepfo ya Danemarke (SDU) ryashatse guhuza iterambere rigenda rikorwa mu bikorwa byo guhindura amashanyarazi akomoka ku mirasire y'izuba (OPV) yakozwe nautakira neza (NFA)ibikoresho hamwe no gutezimbere.

Iri tsinda ryatoranije aside yitwa asikorbike, ikunze kwitwa vitamine C, ikanayikoresha nk'urwego rwa passivation hagati ya zinc oxyde (ZnO) itwara ibintu bya elegitoronike (ETL) hamwe n'ifoto ifotora yo mu tugari twa NFA OPV yahimbwe n'ibikoresho bitavunitse hamwe na a igice cya kabiri cya polymer (PBDB-T: IT-4F).

Abashakashatsi bubatse ingirabuzimafatizo hamwe na indium tin oxyde (ITO), ZnO ETL, vitamine C, vitamine C, PBDB-T: imashini itwara IT-4F, oxyde ya molybdenum (MoOx) itoranya, hamwe na feza (Ag ) guhuza ibyuma.

Itsinda ryasanze aside ya asikorbike itanga ingaruka zifotora, itangaza ko ibikorwa bya antioxydeant bigabanya inzira zangiza ziterwa no guhura na ogisijeni, urumuri nubushyuhe. Ubushakashatsi bwerekanye ko ibizamini nka ultraviolet bigaragara ko byinjira, impedance spectroscopy, voltage iterwa n’umucyo hamwe n’ibipimo bigezweho, byanagaragaje ko vitamine C igabanya ifoto ya molekile ya NFA kandi igahagarika kwishyuza.

Isesengura ryabo ryerekanye ko, nyuma ya 96 h yo gukomeza gufotora munsi yizuba 1, ibikoresho bikubiyemo vitamine C bigumana 62% byagaciro kambere, hamwe nibikoresho byerekanaga 36% gusa.

Ibisubizo byerekanaga kandi ko inyungu zihamye zitaje ku kiguzi cyo gukora neza. Igikoresho cya nyampinga cyageze ku mikorere ya 9,97% yingufu, umuyagankuba ufunguye wa 0,69 V, umuyagankuba mugufi wa 21.57 mA / cm2, hamwe na 66% byuzuye. Ibikoresho byifashishwa bitarimo vitamine C, byagaragaje 9,85% bikora neza, umuyagankuba ufunguye wa 0.68V, umuyoboro mugufi wa 21.02 mA / cm2, hamwe na 68% byuzuye.

Abajijwe kubyerekeranye nubucuruzi nubunini, Vida Engmann uyobora itsinda kuriIkigo cya Photovoltaque igezweho hamwe nibikoresho bito bitanga ingufu (SDU CAPE), yatangarije ikinyamakuru pv, ati: "Ibikoresho byacu muri ubu bushakashatsi byari 2,8 mm2 na 6,6 mm2, ariko birashobora gukorerwa muri laboratoire yacu yo kuzunguruka kuri SDU CAPE aho dusanzwe duhimba na modul ya OPV."

Yashimangiye ko uburyo bwo gukora bushobora gupimwa, agaragaza ko urwego rw’imbere ari “uruganda ruhendutse rushobora gukemuka mu mashanyarazi asanzwe, bityo rukaba rushobora gukoreshwa mu buryo bwo gutwikira umuzingo nk'izindi nzego” muri selire ya OPV.

Engmann abona ubushobozi bwinyongera zirenze OPV mubindi bikoresho bya gatatu byikoranabuhanga rya selile, nka selile yizuba ya perovskite hamwe ningirabuzimafatizo zikomoka ku mirasire y'izuba (DSSC). Ati: "Ubundi buryo bwa tekinoloji bushingiye ku binyabuzima / bivangavanze nka DSSC na selile izuba rya perovskite, bifite ibibazo bisa nk’imirasire y’izuba, bityo rero hari amahirwe menshi yo kugira uruhare mu gukemura ibibazo by’umutekano muri ubwo buhanga."

Akagari katanzwe mu mpapuro “Vitamine C ku Ifoto-Ihamye Non-fullerene-yemera-Imirasire y'izuba, ”Byasohotse muriACS Ikoreshwa ryibikoresho.Umwanditsi wambere wimpapuro ni SDU CAPE's Sambathkumar Balasubramanian. Iri tsinda ryarimo abashakashatsi bo muri kaminuza ya SDU na Rey Juan Carlos.

Urebye imbere itsinda rifite gahunda yo gukora ubushakashatsi muburyo bwo gutuza hakoreshejwe antioxydants isanzwe. Engmann yagize ati: "Mu bihe biri imbere, tugiye gukomeza gukora iperereza muri iki cyerekezo."
