Cov kws tshawb fawb txog lub cev ntawm ITMO University tau tshawb pom ib txoj hauv kev tshiab los siv cov ntaub ntawv pob tshab hauvcov roj teeb hnub cithaum tseem tswj tau lawv txoj kev ua haujlwm zoo. Cov thev naus laus zis tshiab no yog raws li cov txheej txheem doping, uas hloov cov khoom ntawm cov ntaub ntawv los ntawm kev ntxiv cov khoom tsis huv tab sis tsis tas siv cov khoom siv tshwj xeeb kim.

Cov txiaj ntsig ntawm kev tshawb fawb no tau muab luam tawm hauv ACSAplied Materials & Interfaces (“Ion-gated small molecule OPVs: Interfacial doping of charge collectors and transport layers”).

Ib qho ntawm cov teeb meem loj tshaj plaws hauv lub zog hnub ci yog kev tsim cov ntaub ntawv nyias nyias uas pom tseeb. Cov ntaub ntawv no tuaj yeem siv rau saum cov qhov rai ib txwm kom tsim hluav taws xob yam tsis cuam tshuam rau qhov zoo li ntawm lub tsev. Tab sis kev tsim cov hlwb hnub ci uas ua ke nrog kev ua haujlwm zoo nrog kev xa lub teeb zoo yog qhov nyuaj heev.

Cov roj teeb hnub ci uas muaj cov yeeb yaj kiab nyias nyias muaj cov hlau tsis pom kev rov qab uas ntes tau ntau lub teeb. Cov roj teeb hnub ci pob tshab siv cov electrodes xa teeb rov qab. Hauv qhov no, qee cov photons yuav ploj mus thaum lawv dhau mus, ua rau lub cuab yeej ua haujlwm tsis zoo. Ntxiv mus, kev tsim cov electrode rov qab nrog cov khoom tsim nyog tuaj yeem kim heev, "Pavel Voroshilov, tus kws tshawb fawb ntawm ITMO University's School of Physics and Engineering hais.

Qhov teeb meem ntawm kev ua haujlwm tsis zoo yog daws tau los ntawm kev siv doping. Tab sis kev ua kom cov khoom tsis huv raug siv rau cov khoom siv kom raug yuav tsum muaj cov txheej txheem nyuaj thiab cov khoom siv kim. Cov kws tshawb fawb ntawm ITMO University tau tawm tswv yim txog kev siv tshuab pheej yig dua los tsim cov vaj huam sib luag hnub ci "tsis pom" - ib qho uas siv cov kua ionic los dope cov khoom siv, uas hloov cov yam ntxwv ntawm cov txheej txheem ua tiav.

"Rau peb cov kev sim, peb tau siv lub hnub ci me me uas muaj molecule thiab txuas cov nanotubes rau nws. Tom ntej no, peb tau doped cov nanotubes siv lub rooj vag ion. Peb kuj tau ua cov txheej txheem thauj mus los, uas yog lub luag haujlwm rau kev ua Tus nqi los ntawm cov txheej txheem nquag mus txog lub electrode. Peb tau ua qhov no yam tsis muaj lub chamber nqus tsev thiab ua haujlwm nyob rau hauv cov xwm txheej ambient. Txhua yam peb yuav tsum ua yog poob qee cov kua ionic thiab siv me ntsis voltage los tsim cov kev ua tau zoo tsim nyog. "Pavel Voroshilov ntxiv.

Thaum lawv sim lawv cov thev naus laus zis, cov kws tshawb fawb tau ua kom lub roj teeb ua haujlwm tau zoo dua. Cov kws tshawb fawb ntseeg tias tib lub thev naus laus zis no tuaj yeem siv los txhim kho kev ua haujlwm ntawm lwm hom roj teeb hnub ci. Tam sim no lawv npaj yuav sim nrog cov ntaub ntawv sib txawv thiab txhim kho cov thev naus laus zis doping nws tus kheej.
