Izazi zeFiziksi e-ITMO University zithole indlela entsha yokusebenzisa izinto ezibonakalayoamaseli elangangenkathi igcina ukusebenza kahle kwazo.Ubuchwepheshe obusha busekelwe ezindleleni ze-doping, ezishintsha izakhiwo zezinto ngokungeza ukungcola kodwa ngaphandle kokusebenzisa imishini ekhethekile ebizayo.

Imiphumela yalolu cwaningo ishicilelwe kokuthi ACSApplied Materials & Interfaces (“Ama-OPVs emolekyuli encane ene-ion-gated: I-interface doping yabaqoqi bezimali nezendlalelo zokuthutha”).

Enye yezinselelo ezithakazelisa kakhulu kumandla elanga ukuthuthukiswa kwezinto ezibonakalayo ezibonisa ukukhanya kwefilimu emincane emincane.Ifilimu ingasetshenziswa phezu kwamafasitela ajwayelekile ukukhiqiza amandla ngaphandle kokuphazamisa ukubukeka kwesakhiwo.Kodwa ukuthuthukisa amaseli elanga ahlanganisa ukusebenza kahle okuphezulu nokudluliswa kokukhanya okuhle kunzima kakhulu.

Amaseli elanga anefilimu elincanyana elivamile anoxhumana nabo bensimbi obuyi-opaque abathwebula ukukhanya okwengeziwe.Amaseli elanga abonisa ngale asebenzisa ama-electrode angemuva adlulisa ukukhanya.Kulokhu, amanye ama-photon alahleka nakanjani njengoba edlula, okona ukusebenza kwedivayisi.Ngaphezu kwalokho, ukukhiqiza i-electrode engemuva enezakhiwo ezifanele kungabiza kakhulu,” kusho uPavel Voroshilov, umcwaningi eSikoleni seFiziksi nobunjiniyela se-ITMO University.

Inkinga yokusebenza kahle okuphansi ixazululwa ngokusebenzisa i-doping.Kodwa ukuqinisekisa ukuthi ukungcola kusetshenziswe ngendlela efanele ezintweni kudinga izindlela eziyinkimbinkimbi nemishini ebizayo.Abacwaningi base-ITMO University bahlongoze ubuchwepheshe obushibhile bokudala ama-solar panel "angabonakali" - osebenzisa uketshezi lwe-ionic ukwenza i-dope impahla, eshintsha izakhiwo zezendlalelo ezicutshungulwayo.

”Ezivivinyweni zethu, sithathe iseli elincane lelanga elisuselwa ku-molecule futhi sanamathisela ama-nanotube kulo.Okulandelayo, siphonsa ama-nanotubes sisebenzisa isango le-ion.Siphinde sacubungula isendlalelo sezokuthutha, esinesibopho sokwenza Ukushaja okuvela kungqimba olusebenzayo kufinyelela ngempumelelo ku-electrode.Sikwazile ukwenza lokhu ngaphandle kwe-vacuum chamber futhi sisebenza ngaphansi kwezimo ezizungezile.Okwakufanele sikwenze nje ukulahla uketshezi oluthile lwe-ionic futhi sisebenzise i-voltage encane ukukhiqiza ukusebenza okudingekayo.” kwengeza uPavel Voroshilov.

Ekuhloleni ubuchwepheshe babo, ososayensi bakwazile ukwandisa kakhulu ukusebenza kahle kwebhethri.Abacwaningi bakholelwa ukuthi ubuchwepheshe obufanayo bungasetshenziswa ukuthuthukisa ukusebenza kwezinye izinhlobo zamaseli elanga.Manje bahlela ukuhlola izinto ezahlukene futhi bathuthukise ubuchwepheshe be-doping ngokwayo.
