Iingcali zefiziksi kwiYunivesithi ye-ITMO zifumene indlela entsha yokusebenzisa izinto ezicacileyo kwiiiseli zelangangelixa zigcina ukusebenza kwazo kakuhle. Le teknoloji intsha isekelwe kwiindlela zokusebenzisa iziyobisi, ezitshintsha iimpawu zezinto ngokongeza ukungcola kodwa ngaphandle kokusebenzisa izixhobo ezikhethekileyo ezibizayo.

Iziphumo zolu phando zipapashwe kwi-ACSAPlied Materials & Interfaces (“Ion-gated small molecule OPVs: Interfacial doping of charge collectors and transport layers”).

Enye yezona ngxaki zinomdla kakhulu kumandla elanga kukuphuhliswa kwezinto ezibonakalayo ezibonisa ukukhanya kwefilimu encinci. Ifilimu ingafakwa phezu kweefestile eziqhelekileyo ukuvelisa amandla ngaphandle kokuchaphazela inkangeleko yesakhiwo. Kodwa ukuphuhlisa iiseli zelanga ezidibanisa ukusebenza kakuhle kunye nokuhanjiswa kokukhanya okuhle kunzima kakhulu.

Iiseli zelanga eziqhelekileyo ezinefilimu encinci zinemibhobho engasemva yesinyithi engacacanga ebamba ukukhanya okungakumbi. Iiseli zelanga ezicacileyo zisebenzisa ii-electrode ezingasemva ezithumela ukukhanya. Kule meko, ezinye ii-photon ziyalahleka ngokungenakuphepheka njengoko zidlula, nto leyo eyonakalisa ukusebenza kwesixhobo. Ngaphezu koko, ukuvelisa i-electrode engasemva eneempawu ezifanelekileyo kunokubiza kakhulu,” utshilo uPavel Voroshilov, umphandi kwiSikolo seFiziksi noBunjineli kwiYunivesithi ye-ITMO.

Ingxaki yokusebenza kancinci isonjululwa ngokusebenzisa i-doping. Kodwa ukuqinisekisa ukuba ukungcola kusetyenziswa ngokuchanekileyo kwizinto ezisetyenzisiweyo kufuna iindlela ezintsonkothileyo kunye nezixhobo ezibizayo. Abaphandi kwiYunivesithi ye-ITMO bacebise iteknoloji engabizi kakhulu yokwenza iiphaneli zelanga "ezingabonakaliyo" - leyo isebenzisa ulwelo lwe-ionic ukwenza i-doping yezinto ezisetyenzisiweyo, nto leyo etshintsha iimpawu zeeleya ezicutshungulwayo.

"Kwizilingo zethu, sithathe iseli yelanga encinci esekelwe kwimolekyuli saza sancamathisela ii-nanotubes kuyo. Okulandelayo, safaka ii-nanotubes sisebenzisa isango le-ion. Sikwacubungule umaleko wokuthutha, onoxanduva lokwenza itshaja evela kumaleko osebenzayo ifikelele ngempumelelo kwi-electrode. Sakwazi ukwenza oku ngaphandle kwegumbi lokucoca umoya kwaye sisebenza phantsi kweemeko ezingqongileyo. Ekuphela kwento esasifanele siyenze kukulahla ulwelo lwe-ionic size sisebenzise i-voltage encinci ukuvelisa ukusebenza okufunekayo." wongeze uPavel Voroshilov.

Ekuvavanyeni ubuchwepheshe babo, izazinzulu zikwazile ukwandisa kakhulu ukusebenza kakuhle kwebhetri. Abaphandi bakholelwa ukuba obu buchwepheshe bufanayo bunokusetyenziswa ukuphucula ukusebenza kwezinye iintlobo zeeseli zelanga. Ngoku baceba ukuzama izixhobo ezahlukeneyo nokuphucula ubuchwepheshe bokusebenzisa iziyobisi ngokwazo.
