Ukusebenzisa Izakhi Zomhlaba Ezingavamile Ukuze Unqobe Imikhawulo Yamaseli Elanga
Amaseli elanga e-Perovskite anezinzuzo ngaphezu kobuchwepheshe bamanje be-solar cell.Zinamandla okusebenza kahle kakhulu, azisindi, futhi zibiza kancane kunezinye izinhlobo.Kuseli yelanga ye-perovskite, ungqimba lwe-perovskite lufakwe phakathi kwe-electrode esobala ngaphambili kanye ne-electrode ekhanyayo ngemuva kweseli. Izendlalelo zokuthutha nge-electrode nezimbobo zokuthutha zifakwa phakathi kwe-cathode ne-anode interfaces, okusiza ukuqoqwa kwenkokhelo kuma-electrode. Kunezigaba ezine zamaseli elanga e-perovskite asekelwe esakhiweni se-morphology kanye nokulandelana kwesendlalelo sesendlalelo sokuthutha esishaja: i-planar evamile, i-inverted planar, i-mesoporous evamile, nezakhiwo ze-mesoporous ezihlanekezelwe. Kodwa-ke, kunezithiyo eziningana ngobuchwepheshe.Ukukhanya, umswakama, nomoya-mpilo kungabangela ukonakala kwazo, ukumuncwa kwazo kungase kungafani, futhi ziphinde zibe nezinkinga zokuhlanganisa kabusha okungeyona imisebe.I-Perovskites ingagqwala ngama-electrolyte e-liquid, okuholela ezinkingeni zokuzinza. Ukuze kufezeke ukusetshenziswa kwazo okungokoqobo, kufanele kwenziwe intuthuko ekusebenzeni kahle kokuguqulwa kwamandla kanye nokuzinza kokusebenza.Kodwa-ke, intuthuko yakamuva kwezobuchwepheshe iholele kumaseli elanga e-perovskite ane-25.5% esebenza kahle, okusho ukuthi awekho kude ngemuva kwamaseli elanga avamile we-silicon photovoltaic. Kuze kube manje, izakhi zomhlaba ezingavamile ziye zahlolwa ukuze zisetshenziswe kumaseli elanga e-perovskite.Banezakhiwo ze-photophysical ezinqoba izinkinga.Ukuwasebenzisa kumaseli elanga e-perovskite ngakho-ke kuzothuthukisa izakhiwo zabo, kubenze basebenze kangcono ekusetshenzisweni okukhulu kwezixazululo zamandla ahlanzekile. I-Earth Elements Isiza Kanjani I-Perovskite Solar Cells Kunezinto eziningi ezinenzuzo izakhi zomhlaba ezingavamile ezinazo ezingasetshenziswa ukuthuthukisa umsebenzi walesi sizukulwane esisha samaseli elanga.Okokuqala, amandla e-oxidation kanye nokunciphisa kuma-ion asemhlabeni angavamile ayahlehliswa, kunciphisa i-oxidation yezinto eziqondiwe kanye nokunciphisa.Ukwengeza, ukwakheka kwefilimu elincanyana kungalawulwa ngokungezwa kwalezi zakhi ngokuzihlanganisa nazo zombili i-perovskites kanye nokushaja ama-oxide ensimbi ensimbi. Ngaphezu kwalokho, isakhiwo sesigaba kanye nezakhiwo ze-optoelectronic zingalungiswa ngokuzishumeka endaweni ye-crystal lattice.Ukunciphisa ukungasebenzi kungafinyelelwa ngempumelelo ngokuwashumeka kokokusebenza okuqondiwe noma ngokuhlangana emingceleni yokusanhlamvu noma endaweni yokokusebenza. Ngaphezu kwalokho, ama-photons e-infrared kanye ne-ultraviolet angaguqulwa abe ukukhanya okusabela kwe-perovskite ngenxa yokuba khona kwemizila eguquguqukayo eminingi kuma-ion angavamile emhlabeni. Izinzuzo zalokhu zikabili: igwema ukuthi ama-perovskite alinyazwe ukukhanya okunamandla futhi andise ububanzi bokuphendula okubonakalayo.Ukusebenzisa izakhi zomhlaba ezingavamile kuthuthukisa kakhulu ukuzinza nokusebenza kahle kwamaseli elanga e-perovskite. Ukushintsha I-Morphologies Yamafilimu Amancane Njengoba kushiwo ngaphambili, izakhi zomhlaba ezingavamile zingashintsha i-morphologies yamafilimu amancane ahlanganisa ama-oxide ensimbi.Kubhalwe kahle ukuthi i-morphology yesendlalelo sokuthutha esingaphansi kwenkokhelo ithonya i-morphology yesendlalelo se-perovskite kanye nokuxhumana kwayo nesendlalelo sokuthutha okukhokhiswayo. Isibonelo, ukusebenzisa i-doping ngama-ion asemhlabeni angavamile kuvimbela ukuhlangana kwama-nanoparticles e-SnO2 angabangela ukukhubazeka kwesakhiwo, futhi kunciphise ukwakheka kwamakristalu amakhulu e-NiOx, kwakhe ungqimba olufana noluhlangene lwamakristalu.Ngakho-ke, amafilimu amancane alezi zinto ngaphandle kwamaphutha angafinyelelwa nge-doping engavamile. Ukwengeza, ungqimba lwe-scaffold kumaseli e-perovskite anesakhiwo se-mesoporous sidlala indima ebalulekile koxhumana nabo phakathi kwe-perovskite kanye nezingqimba zokuthutha zokushaja kumaseli elanga.Ama-nanoparticles kulezi zakhiwo angabonisa amaphutha e-morphological kanye nemingcele eminingi yokusanhlamvu. Lokhu kuholela ekuhlanganisweni kweshaja engelona imisebe embi futhi ebucayi.Ukugcwaliswa kwezimbotshana nakho kuyinkinga.Ukusebenzisa i-Doping ngama-ion angavamile emhlabeni kulawula ukukhula kwe-scaffold futhi kunciphisa amaphutha, kudala ama-nanostructures aqondile futhi afanayo. Ngokuhlinzeka ngokuthuthukiswa kwesakhiwo se-morphological ye-perovskite kanye nezendlalelo zokuthutha ezikhokhiswayo, ama-ion omhlaba angavamile angathuthukisa ukusebenza okuphelele nokuzinza kwamaseli elanga e-perovskite, okuwenza afaneleke kakhulu ekusetshenzisweni kwezentengiselwano ezinkulu. Ukubaluleka kwamaseli elanga e-perovskite akukwazi ukuncishiswa.Bazohlinzeka ngomthamo ophezulu wokukhiqiza amandla ngezindleko eziphansi kakhulu kunamaseli elanga asekelwe ku-silicon amanje emakethe.Ucwaningo luye lwabonisa ukuthi i-doping perovskite ene-ion engavamile yomhlaba ithuthukisa izakhiwo zayo, okuholela ekuthuthukisweni kokusebenza kahle nokuzinza.Lokhu kusho ukuthi amaseli elanga e-perovskite asebenza kangcono ayisinyathelo esisodwa sokusondela ekubeni ngokoqobo.
