Abahanga mu bya fiziki muri Kaminuza ya ITMO bavumbuye uburyo bushya bwo gukoresha ibikoresho bibonerana muriuturemangingo tw'izubamu gihe bakomeza gukora neza. Ikoranabuhanga rishya rishingiye ku buryo bwo gukoresha imiti igabanya ubukana bw'ibiyobyabwenge, buhindura imiterere y'ibikoresho binyuze mu kongeramo imyanda ariko hatabayeho gukoresha ibikoresho byihariye bihenze.

Ibisubizo by'ubu bushakashatsi byasohotse muri ACSApplied Materials & Interfaces (“Ion-gated small molecule OPVs: Interfacial doping of charge collectors and transport layers”).

Imwe mu mbogamizi zishishikaje cyane mu ngufu zikomoka ku mirasire y'izuba ni ugukora ibikoresho bibonerana kandi bipima urumuri. Iyi filime ishobora gushyirwa hejuru y'amadirishya asanzwe kugira ngo itange ingufu nta ngaruka ku nyubako. Ariko guteza imbere uturemangingo tw'izuba duhuza imikorere myiza n'urumuri rwiza biragoye cyane.

Uturemangingo tw’izuba dusanzwe dufite icyuma gifata inyuma kidasobanutse neza gifata urumuri rwinshi. Uturemangingo tw’izuba dukoresha electrode zohereza urumuri. Muri iki gihe, fotoni zimwe na zimwe zirabura uko zinyuramo, bigatera imikorere mibi y’igikoresho. Byongeye kandi, gukora electrode yo mu mugongo ifite imiterere ikwiye bishobora guhenda cyane,” ibi ni ibyavuzwe na Pavel Voroshilov, umushakashatsi mu Ishuri rya Fiziki n’Ubwubatsi rya Kaminuza ya ITMO.

Ikibazo cyo kudakora neza gikemurwa hakoreshejwe doping. Ariko kugenzura ko imyanda ikoreshwa neza ku bikoresho bisaba uburyo bugoye n'ibikoresho bihenze. Abashakashatsi bo muri Kaminuza ya ITMO batanze igitekerezo cy'ikoranabuhanga rihendutse ryo gukora panels z'izuba "zitagaragara" - rikoresha ibinyobwa bya ioni kugira ngo rikore doping ku bikoresho, rihindura imiterere y'ibice byatunganyijwe.

"Mu bushakashatsi bwacu, twafashe akantu gato k'izuba gashingiye kuri molekile maze tugakora nanotubes. Hanyuma, twakoresheje nanotubes dukoresheje irembo rya ion. Twanatunganyije urwego rw'ubwikorezi, rushinzwe gukora charge iva muri urwo rwego igera neza kuri electrode. Twashoboye kubikora tudafite icyumba cy'ubusamo kandi dukora mu bihe biri hagati y'ikirere. Icyo twagombaga gukora gusa ni ugushyiramo amazi ya ion hanyuma tugashyiraho voltage nke kugira ngo dukore neza." Pavel Voroshilov yongeyeho.

Mu kugerageza ikoranabuhanga ryabo, abahanga mu bya siyansi bashoboye kongera cyane imikorere ya bateri. Abashakashatsi bemeza ko iryo koranabuhanga rishobora gukoreshwa mu kunoza imikorere y'ubundi bwoko bw'uturemangingo tw'izuba. Ubu barateganya kugerageza ibikoresho bitandukanye no kunoza ikoranabuhanga ryo gukoresha imiti igabanya ubukana bw'imisemburo.
