Kusetshenziswa izinto ezingandile-zomhlaba ukunqoba ukulinganiselwa kwamangqamuzana elanga
Umthombo: Izinsizakusebenza ze-Azo Amangqamuzana eSolar eSovar anezinzuzo ngaphezulu kobuchwepheshe be-solar cell. Banamandla okusebenza kahle, abasindayo, futhi babiza imali engaphansi kwezinye izinto ezihlukile. Esitokisini se-perovskite solar, ungqimba we-perovskite uhlanganiswe phakathi kwe-electrode esobala ngaphambili nange-electrode ekhombisa emuva ngemuva kweseli. Izendlalelo ze-Electrode Transport kanye nezendlalelo zokuhamba zeHhole zifakiwe phakathi kwezindawo ze-Calyode kanye ne-Anode interface, enikeza amandla ukuqoqwa kwe-electrodes. Kunezigaba ezine zamangqamuzana e-Purovskite elanga asuselwa esakhiweni se-morphology kanye nokulandelana kwesendlalelo kwesendlalelo sokushaja: iplanethi ejwayelekile, ipulani eliguqukayo, nezinhlaka ezihambisanayo ezihlangene. Kodwa-ke, izingqinamba eziningana zikhona nobuchwepheshe. Ukukhanya, umswakama, nomoya-mpilo kungakunxenxa ukonakaliswa kwabo, ukumunca kwabo kungahle kuthunyelwe, futhi nabo banezinkinga zokubuyiselwa kwemali okungekho emthethweni. Ama-Perovskites angavulwa ngama-electrolytos awuketshezi, okuholela ezindabeni zokuqina. Ukuthola izicelo zabo ezisebenzayo, ukuthuthuka kumele kwenziwe ekusebenzeni kwazo kwamandla nokuqina kokusebenza. Kodwa-ke, intuthuko yakamuva kwezobuchwepheshe iholele kumaseli we-perovskite e-perovskite esebenza kahle ngo-25,5%, okusho ukuthi awekho ngemuva kwe-silicon photovoltaic solar cell. Kuze kube manje, izinto ezivamile zomhlaba ziye zahlolisiswa ngezicelo kumaseli eSolar ePelovskite. Banezakhiwo ze-pitopsysical ezinqoba izinkinga. Ukuzisebenzisa emangqamuzaneni eSovar asePelovskite ngakho-ke kuzothuthukisa izakhiwo zawo, kubenze basebenze ngokwengeziwe ekusetshenzisweni kwamandla amakhulu ezixazululo zamandla ahlanzekile. Izakhi zomhlaba ezingavamile zosizo ama-perovskite amangqamuzana elanga Kunezakhiwo eziningi ezizuzisayo ezikhona izinto zomhlaba ezingavamile ezinazo ezingasetshenziswa ukwenza ngcono ukusebenza kwalesi sizukulwane esisha samaseli elanga. Okokuqala, i-oxidation kanye nokunciphisa amandla asezingeni elingejwayelekile ku-Ions are-Earth ion kuguqulwa, kunciphisa i-oxidation ye-oxidation yokwenziwa kwelitshe. Ngokwengeziwe, ukwakheka kwefilimu emincane kungalawulwa ngokungezwa kwalezi zinto ngokuzihlanganisa nazo zombili ama-perovski kanye namacala okuhambisa i-minal oxides. Ngaphezu kwalokho, ukwakheka kwesigaba nezakhiwo ze-Optoelectronic kungashintshwa ngokuzifaka esikhundleni sabo ku-crystal lattice. Ukuphambuka kwesici kungafinyelelwa ngempumelelo ngokungishukumisela ezintweni eziqondiswe kuyo noma kuhlangana ngemingcele yokusanhlamvu noma endaweni yokwenziwa. Ngaphezu kwalokho, i-infrared ne-ultraviolet popEns ingaguqulwa ibe ukukhanya okubonakalayo okubonakalayo kwe-perovskite ngenxa yokuba khona kwama-orbits aguquguqukayo amaningi ama-orbits angavamile. Izinzuzo zalokhu zingamabili: Kuvimbela ama-Perovskites alimele ukukhanya okuphezulu futhi anwebise uhla lokuphendula okubonakalayo. Esebenzisa izinto zomhlaba ezingandile zithuthukisa ukuqina kanye nokusebenza kahle kwamangqamuzana e-Purovskite elanga. Ukushintsha ama-morphologies amafilimu amancanyana Njengoba kushiwo ngaphambili, izinto zomhlaba ezingavamile zingashintsha ama-morphologies amafilimu amancanyana aqukethe ama-oxides wensimbi. Kubhalwe kahle ukuthi i-morphology yesisekelo sezokuthutha esingaphansi kwezokuthutha ithonya i-morphology ye-perovskite ungqimba kanye nokuxhumana kwayo nesendlalelo sezokuthutha. Isibonelo, ukudonsa nge-arare-Earth ion kuvimbela ukuhlanganiswa kwama-sno2 nanoparticles angadala amakhaza ahlelekile, futhi anciphise ukwakheka kwamakristalu amakhulu we-niox, adala ungqimba lwezinhlamvu ezifanayo. Ngakho-ke, amafilimu angqimba omncane walezi zinto ngaphandle kweziphambeko angatholakala nge-DAR-Earth DOPING. Ngokwengeziwe, ungqimba lwe-scaffold emangqamuzaneni ePelovskite anesakhiwo esimnandi edlala indima ebalulekile koxhumana nabo phakathi kwe-perovskite kanye namacala okuhamba amaseli elanga. Ama-nanoparticles kulezi zinhlaka angabonisa amaphutha e-morphological kanye nemingcele eminingi yama-ray. Lokhu kuholela ekubuyiselweni kwecala elibi ne-radiative. Ukugcwaliswa kwe-pore nakho kuyinkinga. I-DOPING nge-rare-Earth ion ilawula ukukhula okucashile futhi inciphise iziphambeko, ukudala ama-nanostructure aqondaniswe futhi afanayo. Ngokuhlinzeka ngentuthuko yesakhiwo se-morphological of perovskite kanye nezendlalelo zokuhamba, ama-ion angumbala omhlaba angathuthukisa ukusebenza okuphelele nokuqina kwamangqamuzana e-perovskite elanga, abenze balungele izinhlelo zokusebenza ezinkulu ezentengiso. Ukubaluleka kwamangqamuzana e-perovskite solar awakwazi ukubonwa. Bazohlinzeka ngamandla amakhulu okuphehla amandla okuphekela kwamandla aphansi kakhulu kunamaseli we-silico asuselwa ku-silico asemakethe. Lolu cwaningo lukhombisile ukuthi i-doping perovskite ene-rare-Earth ion ithuthukisa izakhiwo zayo, okuholela ekuthuthukisweni kokusebenza kahle nasekuzinyoka. Lokhu kusho ukuthi amangqamuzana elanga e-perovskite asebenza kangcono yilesi sinyathelo esisodwa esiseduze nokuba ngokoqobo.
