Akatswiri a sayansi ya zakuthambo ku yunivesite ya ITMO apeza njira yatsopano yogwiritsira ntchito zinthu zowonekera bwino mumaselo a dzuwapamene akusungabe magwiridwe antchito awo. Ukadaulo watsopanowu umachokera ku njira zogwiritsira ntchito mankhwala osokoneza bongo, zomwe zimasintha mawonekedwe a zipangizo mwa kuwonjezera zinyalala koma popanda kugwiritsa ntchito zida zapadera zokwera mtengo.

Zotsatira za kafukufukuyu zasindikizidwa mu ACSAPlied Materials & Interfaces (“Ma ion-gated small molecule OPVs: Interfacial doping of charge collectors and transport layers”).

Chimodzi mwa zovuta kwambiri pa mphamvu ya dzuwa ndi kupanga zinthu zowonekera bwino zomwe zimathandizira kuwala. Filimuyi imatha kuyikidwa pamwamba pa mawindo wamba kuti ipange mphamvu popanda kusokoneza mawonekedwe a nyumbayo. Koma kupanga maselo a dzuwa omwe amaphatikiza magwiridwe antchito apamwamba komanso kufalitsa bwino kuwala n'kovuta kwambiri.

Maselo a dzuwa opyapyala achikhalidwe amakhala ndi ma contact achitsulo kumbuyo omwe amasunga kuwala kochulukirapo. Maselo a dzuwa owonekera bwino amagwiritsa ntchito ma electrode kumbuyo omwe amatumiza kuwala. Pankhaniyi, ma photon ena amatayika mosalephera akamadutsa, zomwe zimawononga magwiridwe antchito a chipangizocho. Kuphatikiza apo, kupanga ma electrode kumbuyo komwe kuli ndi makhalidwe oyenera kungakhale kokwera mtengo kwambiri,” akutero Pavel Voroshilov, wofufuza ku Sukulu ya Fizikisi ndi Uinjiniya ya ITMO University.

Vuto losagwira ntchito bwino limathetsedwa pogwiritsa ntchito mankhwala ozunguza bongo. Koma kuonetsetsa kuti zinyalalazo zagwiritsidwa ntchito moyenera pa zinthuzo kumafuna njira zovuta komanso zida zodula. Ofufuza ku ITMO University apereka lingaliro la ukadaulo wotsika mtengo wopanga ma solar panels "osaoneka" - womwe umagwiritsa ntchito madzi a ionic kuti agwiritse ntchito mankhwala ozunguza bongo, zomwe zimasintha mawonekedwe a zigawo zomwe zakonzedwa.

"Pa kuyesa kwathu, tinatenga selo laling'ono la dzuwa lochokera ku molekyulu ndikulumikiza ma nanotubes pamenepo. Kenako, tinapanga ma nanotubes pogwiritsa ntchito chipata cha ion. Tinakonzanso gawo loyendetsa, lomwe limayang'anira kupanga. Mphamvu yochokera ku gawo logwira ntchito imafika bwino ku electrode. Tinatha kuchita izi popanda chipinda chotsukira ndikugwira ntchito pansi pa mikhalidwe yozungulira. Chomwe tinkayenera kuchita ndikutaya madzi a ionic ndikugwiritsa ntchito voltage pang'ono kuti tipeze magwiridwe antchito ofunikira." anawonjezera Pavel Voroshilov.

Poyesa ukadaulo wawo, asayansiwa adatha kuwonjezera kwambiri mphamvu ya batri. Ofufuzawo akukhulupirira kuti ukadaulo womwewo ungagwiritsidwe ntchito kukonza magwiridwe antchito a mitundu ina ya maselo a dzuwa. Tsopano akukonzekera kuyesa zinthu zosiyanasiyana ndikukonza ukadaulo wogwiritsa ntchito mankhwala osokoneza bongo.
