Ubutaliyani bwakoze module yizuba ishobora gukomeza gukora neza 90% kuri 85 ° C.

Iriburiro: Itsinda ry’ubushakashatsi riyobowe na kaminuza ya Tor Vergata i Roma, mu Butaliyani ryakoze module yizuba ya peroxide ifite ubuso bungana na cm 42.8 cm2 nubuso bwa santimetero kare 50.Imirasire y'izuba igizwe na serie 14 za bateri ya peroxide ikora neza 20% murukurikirane.Nyuma yamasaha 800 yubushyuhe bwa 85 ° C, irashobora gukomeza gukora neza ya 90%.

Itsinda mpuzamahanga ry’ubushakashatsi ryakoresheje ubwoko bushya bwa doping stratégie yo gushushanya izuba ryitwa peroxide.Bavuga ko ugereranije nibindi bikoresho bishingiye kuri peroxide, module irashobora kugera ku mikorere ihanitse mugihe ikomeza ibikorwa bihamye.

Nubwo imirasire y'izuba ya peroxide isa nkaho iri munzira igana ku musaruro rusange, abantu baracyashishikajwe n'ikoranabuhanga kubera impungenge z’imiterere y’imiterere y’ubwikorezi bwo mu mwobo (HTL) ndetse n’ubukangurambaga bw’ikirere.byagize ingaruka.

Abashakashatsi bavuze ko bashobora guhindura uburemere bwa molekuline (MW) y'ibikoresho byo gutwara umwobo (HTM) byometse kuri polytriarylamine (PTAA).Basobanuye bati: “Kwiyongera kwa monotonic mu kongera ingufu mu guhindura imikorere nk'igikorwa cya MW bifitanye isano no kwiyongera nk'ukwo mu muyoboro w'amashanyarazi ufunguye (VOC), umuyoboro mugufi w'amashanyarazi (JSC), no kuzuza ibintu (FF).Muri ubu buryo, uburyo bwo kwishyuza imbere muri HTL hamwe no gutwara ibicuruzwa kuri interineti ya peroxide / HTL byiyongereye bitewe n'ubunini. ”

Bavuze ko iri terambere ryagerwaho hifashishijwe ingaruka ziterwa na doping hamwe na MW tuning ya MW, ibyo bikaba byageze kuri disikuru ya polaron kumurongo wa polymer.Ubushakashatsi bwa siyansi bwerekanye ko ishyirwaho rya polarone mu ngirabuzimafatizo zikomoka ku mirasire y'izuba ya peroxide ari ikintu gishobora gutuma bateri zikora neza cyane, nubwo uburyo bwihishe inyuma ya polaroni butazwi na gato.Poleon ni ihindagurika ryihuse muri latike ya atome yibikoresho.Ikora hafi ya electron igenda muri tiriyari nkeya yisegonda, hanyuma ikabura.

Ukurikije ubuso bwuzuye bwa santimetero 42.8 hamwe nubuso bwa aperture bwa santimetero kare 50, serie 14 za bateri ya peroxide ifite 20% ikora neza ihujwe mukurikirane kugirango hubakwe akanama gafite ubushobozi bwa 17%.Ubwiyongere bw'imigozi ya defocusing murwego rwa HMW PTAA ntabwo butanga umusanzu wingenzi mugukora neza kwicyuma, ariko kandi bugira ingaruka nziza kumatara ya peroxide yumurongo wimbere, bityo bikazamura umutekano muri rusange.Bavuga ko nyuma yamasaha 1080 yubushyuhe bwa dogere selisiyusi 85, bateri irashobora gukomeza gukora neza mbere ya 90%, kandi nyuma yamasaha 160 yerekanwe, irashobora gukomeza gukora neza bwa 87%.Imirasire y'izuba irashobora gukomeza gukora neza hejuru ya 90% nyuma yamasaha 800 yumuriro wa dogere selisiyusi 85.

Iyi module yatangijwe mu mpapuro “Kugera kuri moderi yizuba ya perovskite itajegajega irenga 17% binyuze muguhindura gahunda ya polaron ya transport ya polymer de transport” yasohotse muri “Nano Energy”.Itsinda ry’ubushakashatsi ririmo abahanga bo muri kaminuza ya Tor Vergata i Roma, mu Butaliyani, muri kaminuza ya Londere, muri kaminuza ya Cambridge mu Bwongereza, no mu kigo cya Max Planck Institute for Polymer Research mu Budage.
