Iingcali zeFiziksi kwiYunivesithi ye-ITMO ziye zafumanisa indlela entsha yokusebenzisa izinto ezicacileyo kwiiiseli zelangangelixa begcina ukusebenza kakuhle kwabo.Itekhnoloji entsha isekelwe kwiindlela zokusebenzisa i-doping, ezitshintsha iipropathi zezinto ngokufaka ukungcola kodwa ngaphandle kokusetyenziswa kwezixhobo ezikhethekileyo ezibizayo.

Iziphumo zolu phando zipapashwe kwi-ACSApplied Materials & Interfaces (“I-OPVs ye-molecule encinci ye-Ion-gated: i-Interfacial doping of chargers and transport layers”).

Omnye weyona miceli mngeni inomdla kumandla elanga kukuphuhliswa kwezinto ezibonakalayo ezicwengileyo zefilimu.Ifilimu ingasetyenziswa phezu kweefestile eziqhelekileyo ukuvelisa amandla ngaphandle kokuchaphazela ukubonakala kwesakhiwo.Kodwa ukuphuhlisa iiseli zelanga ezidibanisa ukusebenza kakuhle kunye nokuhanjiswa kokukhanya okulungileyo kunzima kakhulu.

Iiseli zelanga eziqhelekileyo ezinefilim ecwecwe zineentsimbi ezifipheleyo zokunxibelelana ngasemva ezibamba ukukhanya okungakumbi.Iiseli zelanga ezicacileyo zisebenzisa ii-electrode ezithumela ukukhanya ngasemva.Kule meko, ezinye iifotoni zilahlekile ngokungenakuphepheka njengoko zidlula, zithobisa ukusebenza kwesixhobo.Ngaphezu koko, ukuvelisa i-electrode yangasemva eneempawu ezifanelekileyo kunokubiza kakhulu, "kusho uPavel Voroshilov, umphandi kwiYunivesithi ye-ITMO yeSikolo seFiziksi kunye nobuNjineli.

Ingxaki yokusebenza kakuhle ephantsi isonjululwe ngokusebenzisa i-doping.Kodwa ukuqinisekisa ukuba ukungcola kusetyenziswe ngokuchanekileyo kwizinto eziphathekayo kufuna iindlela ezinzima kunye nezixhobo ezibizayo.Abaphandi kwiYunivesithi ye-ITMO bacebise iteknoloji engabizi kakhulu ukudala iipaneli zelanga "ezingabonakaliyo" - enye esebenzisa i-ionic liquids ukwenza i-dope yezinto eziphathekayo, ezitshintsha iipropati zeeleyile ezicutshungulwayo.

“Kuvavanyo lwethu, sithathe iseli yelanga esekwe kwimolekyuli encinci sancamathisela iinanotubes kuyo.Emva koko, safaka i-nanotubes sisebenzisa isango le-ion.Siphinde sicubungule umaleko wezothutho, onoxanduva lokwenza Intlawulo evela kwinqanaba elisebenzayo lifikelela ngempumelelo kwi-electrode.Sikwazile ukwenza oku ngaphandle kwegumbi lokucoca kunye nokusebenza phantsi kweemeko ezingqongileyo.Ekuphela kwento ekwakufuneka siyenze yayikukulahla ulwelo oluthile lwe-ionic kwaye sisebenzise i-voltage encinci ukuvelisa ukusebenza okuyimfuneko.” wongeza uPavel Voroshilov.

Ekuvavanyeni itekhnoloji yabo, izazinzulu ziye zakwazi ukwandisa kakhulu ukusebenza kwebhetri.Abaphandi bakholelwa ukuba iteknoloji efanayo ingasetyenziselwa ukuphucula ukusebenza kwezinye iintlobo zeeseli zelanga.Ngoku baceba ukuzama izinto ezahlukeneyo kunye nokuphucula iteknoloji yedoping ngokwayo.
