Sebenzisa izinto ezinqabileyo zomhlaba ukoyisa imida yeeseli zelanga
Umthombo: Izixhobo ze-Azo Iiseli ze-Perovskite zolwandle Iiseli ze-Perovskite zeRhafu zinenzuzo kwitekhnoloji yangoku yeSolar. Banako ukusebenzela ngakumbi, balula, kwaye baxabisa ngaphantsi kwezinye izinto ezahlukeneyo. Kwiseli ye-Perovskite yesele, umaleko we-perovskite yisandwity phakathi kwe-elektrode ebonakalayo ngaphambili kunye ne-electrode eclive ngasemva kwiseli. I-Electrode yezothutho kunye neeNdawo zoThutho zeHole zifakwe phakathi kwe-Cathode kunye ne-infoder, eququzelele ukuqokelelwa kwentlawulo kwi-electros. Kukho ukuhlelwa kwezine zeeseli ze-perovskite ze-perovskite ze-morphology kunye nokulandelelana kobeko lwezothutho: Clithar rhoqo, iZiko le-Intanethi, kunye nezakhiwo zonqulo eziphezulu. Nangona kunjalo, iindlela ezininzi zokuzonwabisa zikhona ngetekhnoloji. Ukukhanya, ukufuma, kunye neoksijini kunokubangela ukonakala kwabo, ukufunxa kwabo kunokubekwa mthethweni, kwaye nabo banemicimbi enombulelo ongazenzisiyo. I-Perovskites inokuchithwa ngama-elektrodys yolwelo, ekhokelela kwimicimbi yozinzo. Ukufezekisa izicelo zabo ezisebenzayo, kufuneka zenziwe ekugqityweni kwamandla abo kunye nokuzinza okusebenzayo. Nangona kunjalo, inkqubela phambili kwitekhnoloji ikhokelele kwiiseli ze-Perovskite ze-Perovskite ze-SOR nge-25,5% yokusebenza kakuhle, okuthetha ukuba azikude neeseli zeFoticon Photovtaic Solar. Ukuza kuthi ga ngoku, izinto ezinqabileyo zomhlaba ezinqabileyo ziphononongiwe kwizicelo kwiiseli ze-Perovskite ze-Perovskite zolwandle. Banazo iipropathi zefoto ezoyikisayo iingxaki. Ukuzisebenzisa kwiiseli ze-Perovskite Solar kuya kuthi ke kuphuculwe iipropathi zabo, zibenza babe nakho ukusebenza ngakumbi ukuze kuphunyezwe izisombululo zamandla ezicocekileyo. INDLELA YOKUZIPHATHA KAKHULU NJANI ZINJONGO ZABASEBENZI ZE-PERVSKIte Zininzi iipropathi ezifanelekileyo ezinqabileyo zomhlaba ezinqabileyo onazo zinokusetyenziselwa ukuphucula umsebenzi wesi sizukulwana sitsha seeseli zelanga. Okokuqala, i-oxidation kunye nokuncitshiswa kwamandla e-ion yomhlaba onqabileyo kuguqukele, ukunciphisa i-oxidation ye-oxivide yakho kunye nokuncitshiswa. Ukongeza, ukuqulunqwa kwefilimu omncinci kunokulawulwa ngokuphuculwa kwezi zinto ngokudibanisa nazo zombini iiperovskites kunye nokuhlawula i-oxide yentsimbi. Ngaphaya koko, ubume besigaba kunye neepropathi ze-optoectergesect zinokuhlengahlengiswa ngokubenzayo kwi-crystal lattle. Ukudluliselwa kwesiphene kunokufezekiswa ngempumelelo ngokungenisa kwizinto ekujoliswe kuzo nokuba zenziwe ngaphakathi kwimida yengqolowa okanye kumgangatho wezinto ezibonakalayo. Ngapha koko, infrared kunye neefoto ze-ultraviolet zinokuguqulwa zibe yi-Perovskite ephendulweyo ephendulayo kwi-Ortiction yobukho bezinto ezinamandla zenguqu kwi-ions enqabileyo. Izibonelelo zezi zimbini: Ithintela i-perovskites yonakaliswe kukukhanya okukhulu kwaye kwandiswa uluhlu lokuphendula ngezinto ezibonakalayo. Sebenzisa izinto ezinqabileyo zomhlaba kuphucula kakhulu uzinzo kunye nokusebenza kakuhle kweeseli ze-Perovskite ze-Perovskite. Ukuguqula i-morphologues yeefilimu ezinqabileyo Njengoko bekutshiwo ngaphambili, izinto zomhlaba ezinqabileyo zinokuguqula i-morphologues zefilimu ezincinci ezibandakanya ii-oxide zentsimbi. Kubhalwe kakuhle ukuba i-morphology yentlawulo yothutho iphembelela i-morphology ye-Perovskite ye-Perovskite kunye nokudibana kwayo nolwakhiwo lwezothutho. Umzekelo, ukudlala ii-ion zomhlaba ezinqabileyo zithintela ukudityaniswa kwee-NanaPalles ze-Nanaplorles ezinokubangela iziphene ze-Sno2 ezinokubangela iziphene, kwaye zinciphisa isakhiwo sekristali enkulu ye-niox, iyunifomu enkulu kunye ne-compact ye-crystals. Ke, iifilimu ezingamanyambi ezinamathele kwezi zinto ngaphandle kweziphene zinokufezekiswa ngomhlaba onqabileyo. Ukongeza, umaleko we-stalfold kwiiseli ze-Perovskite ezinesakhiwo somoya esinendima ebalulekileyo kubafowunelwa phakathi kwe-Perovskite kunye ne-ntlawulo kwiiseli zelanga. I-Nanoprelles kwezi zakhiwo inokubonisa iziphene zengqondo kunye nemida emininzi yokudla okuziinkozo. Oku kukhokelela kwimbuyekezo engathethekiyo kwaye imbi engaphenduliyo. Ukugcwaliswa kwe-pore kukwo nangomcimbi. Ukudlala ii-ion zomhlaba ezinqabileyo zilawula ukukhula kwesicatshulwa kwaye kunciphisa iziphene, ukudala ulwakhiwo kunye nolwakhiwo olufanayo. Ngokubonelela ngophuculo lwezinto ezenziwa yi-morphological ye-Perovskite kunye nezothutho zeThutha, umhlaba onqabileyo unokuphucula intsebenzo kunye nokuzinza kweeseli ze-perovskite, zenza ukuba zilungele ukusetyenziswa kwezicelo ezikhulu zokuthengisa. Ukubaluleka kweeseli ze-perovskite ze-shoron akunakubandakanywa. Baza kubonelela ngomthamo wokuvelisa amandla aphezulu kwindleko eziphantsi kakhulu kuneziseli zelanga ezisekwe kwi-solar kwintengiso. Olu phononongo lubonakalisile ukuba i-perovskite ene-ion yomhlaba enqabileyo iphucula iipropathi zayo, ezikhokelela kuphuculo ekusebenzeni nasekuzinziweni. Oku kuthetha ukuba iiseli ze-Perovskite ze-surovskite ze-solar kunye nentsebenzo ephucukileyo lisondela kwinyathelo elinye ukuba libe yinto yokwenene.
