Akatswiri a sayansi ya zakuthambo ku yunivesite ya ITMO apeza njira yatsopano yogwiritsira ntchito zinthu zowonekerama cell a dzuwapamene kusunga mphamvu zawo.Ukadaulo watsopano umachokera ku njira za doping, zomwe zimasintha mawonekedwe azinthu powonjezera zonyansa koma popanda kugwiritsa ntchito zida zapadera zamtengo wapatali.

Zotsatira za kafukufukuyu zasindikizidwa mu ACSApplied Materials & Interfaces ("Ma molekyu ang'onoang'ono a ion-gated OPVs: Interfacial doping of chargers and transport layers").

Chimodzi mwazovuta zochititsa chidwi kwambiri pamagetsi adzuwa ndi kupanga zinthu zowoneka bwino zamafilimu owoneka bwino.Filimuyi ingagwiritsidwe ntchito pamwamba pa mawindo wamba kuti apange mphamvu popanda kusokoneza maonekedwe a nyumbayo.Koma kupanga ma cell a solar omwe amaphatikiza bwino kwambiri ndi njira yabwino yolumikizira kuwala ndizovuta kwambiri.

Maselo owoneka bwino a solar amtundu wopyapyala amakhala ndi zolumikizira zachitsulo zowoneka bwino zomwe zimatenga kuwala kochulukirapo.Ma cell a solar owonekera amagwiritsa ntchito ma elekitirodi otumiza kuwala kumbuyo.Pamenepa, ma photon ena amatayika mosapeŵeka pamene akudutsa, kunyozetsa ntchito ya chipangizocho.Komanso, kupanga electrode yam'mbuyo yokhala ndi zinthu zoyenera kungakhale kokwera mtengo kwambiri, "anatero Pavel Voroshilov, wofufuza pa ITMO University's School of Physics and Engineering.

Vuto la kuchepa kwachangu limathetsedwa pogwiritsa ntchito doping.Koma kuonetsetsa kuti zonyansazo zimagwiritsidwa ntchito moyenera pazinthuzo zimafuna njira zovuta komanso zida zodula.Ofufuza ku yunivesite ya ITMO apereka njira yotsika mtengo yopangira ma solar "osaoneka" - omwe amagwiritsa ntchito zakumwa za ionic kuti awononge zinthuzo, zomwe zimasintha zomwe zimapangidwira.

"Pazoyeserera zathu, tidatenga kaselo kakang'ono ka solar ka molekyulu ndikuyikamo ma nanotubes.Kenako, tidatsitsa ma nanotubes pogwiritsa ntchito chipata cha ion.Tidakonzanso wosanjikiza woyendetsa, womwe umayang'anira kupanga Malipiro kuchokera pagawo logwira ntchito amafika bwino pa electrode.Tinatha kuchita izi popanda chipinda chounikira ndikugwira ntchito pamalo ozungulira.Zomwe tinkachita ndikugwetsa madzi a ionic ndikuyika magetsi pang'ono kuti tigwire ntchito yofunikira."Anawonjezera Pavel Voroshilov.

Poyesa luso lawo, asayansi adatha kuonjezera kwambiri mphamvu ya batri.Ofufuzawo amakhulupirira kuti ukadaulo womwewo ungagwiritsidwe ntchito kukonza magwiridwe antchito amtundu wina wa maselo adzuwa.Tsopano akukonzekera kuyesa zida zosiyanasiyana ndikuwongolera ukadaulo wa doping womwe.
