"Nature" magazine luam tawm ib txoj kev tshiab tsim los ntawm University of Michigan nyob rau hauv lub tebchaws United States, inducing electrons "mus taug kev" nyob rau hauv cov ntaub ntawv organic.fullerenes, deb tshaj qhov txwv yav tas los ntseeg.Txoj kev tshawb no tau nce lub peev xwm ntawm cov khoom siv organic rau lub hnub ci cell thiab semiconductor kev tsim khoom, lossis yuav hloov cov kev cai ntawm kev ua si ntawm kev lag luam.

Tsis zoo li cov hnub ci inorganic, uas tau siv dav niaj hnub no, cov ntaub ntawv organic tuaj yeem ua rau pheej yig hloov pauv cov ntaub ntawv carbon-based, xws li plastics.Cov neeg tsim khoom tuaj yeem tsim cov coils ntawm ntau yam xim thiab teeb tsa thiab laminate lawv seamlessly rau yuav luag txhua qhov chaw.ntawm.Txawm li cas los xij, qhov tsis zoo conductivity ntawm cov khoom siv organic tau cuam tshuam kev nce qib ntawm kev tshawb fawb ntsig txog.Tau ntau xyoo, kev ua tsis zoo ntawm cov organic teeb meem tau pom tias yog kev zam, tab sis qhov no tsis yog ib txwm muaj.Cov kev tshawb fawb tsis ntev los no tau pom tias cov hluav taws xob tuaj yeem txav tau ob peb centimeters hauv ib txheej nyias ntawm fullerene, uas yog qhov zoo kawg.Hauv cov roj teeb organic tam sim no, cov hluav taws xob tsuas tuaj yeem mus txog ntau pua nanometers lossis tsawg dua.

Cov hluav taws xob txav ntawm ib lub atom mus rau lwm qhov, ua ib qho tam sim no hauv lub hnub ci cell lossis hluav taws xob tiv thaiv.Nyob rau hauv inorganic solar cells thiab lwm yam semiconductors, silicon yog dav siv.Nws cov atomic network nruj nreem tso cai rau cov electrons hla tau yooj yim.Txawm li cas los xij, cov ntaub ntawv organic muaj ntau qhov kev sib txuas ntawm ib tus neeg molecules uas ntxiab electrons.Qhov no yog cov organic.Tuag tsis muaj zog.

Txawm li cas los xij, qhov kev tshawb pom tshiab tshaj plaws qhia tau hais tias nws muaj peev xwm kho cov conductivity ntawm nanocov ntaub ntawv fullerenenyob ntawm daim ntawv thov tshwj xeeb.Kev txav dawb ntawm electrons hauv cov organic semiconductors muaj qhov cuam tshuam loj heev.Piv txwv li, tam sim no, saum npoo ntawm lub hnub ci ntawm lub hnub ci yuav tsum tau them nrog cov hluav taws xob hluav taws xob los khaws cov hluav taws xob los ntawm qhov chaw tsim hluav taws xob, tab sis cov hluav taws xob tsis muaj hluav taws xob tso cai rau cov khoom siv hluav taws xob khaws cia ntawm qhov chaw deb ntawm electrode.Ntawm qhov tod tes, cov tuam txhab lag luam tseem tuaj yeem txo cov hluav taws xob hluav taws xob mus rau hauv qhov tsis pom kev sib txuas, paving txoj hauv kev rau kev siv cov pob tshab ntawm lub qhov rais thiab lwm qhov chaw.

Cov kev tshawb pom tshiab tau qhib lub qab ntug tshiab rau cov neeg tsim qauv ntawm cov organic solar cells thiab cov khoom siv hluav taws xob semiconductor, thiab qhov muaj peev xwm ntawm kev xa hluav taws xob tej thaj chaw deb nthuav tawm ntau qhov ua tau zoo rau cov cuab yeej siv hluav taws xob.Nws tuaj yeem tso lub hnub ci ntawm cov khoom siv niaj hnub xws li lub tsev facades lossis qhov rais, thiab tsim hluav taws xob hauv qhov pheej yig thiab yuav luag tsis pom.
