Mu nganda za Photovoltaic, PerovsKite yabaye ishyushye mumyaka yashize. Impamvu yagaragaye ko ari "ukunda" mumirima yizuba biterwa nibidasanzwe. Calcium titanium ore ifite ibintu byinshi byiza byamafoto, inzira yoroshye yo gutegura, hamwe nibikoresho byinshi byibimenyetso nibikoresho byinshi. Byongeye kandi, PerovsKite irashobora kandi gukoreshwa mubutaka bwimbaraga zubutaka, indege, ubwubatsi, ibikoresho byambaye ubusa hamwe nibindi byinshi.
Ku ya 21 Werurwe, ibihe byijoro byasabye ipantaro ya "Calcium Titanite, uburyo bwo gutegura no gutunganya ibikoresho by'ingufu". Mu myaka yashize, ashyigikiye politiki n'ingamba zo mu ngo, Inganda za Calcium-Titanium, ihagarariwe na Calcium-Titanium Ore selile zinshi. None Perovskite ni iki? Nigute inganda za Perovskite? Ni izihe ngorane zikiri izo? Ubumenyi n'ikoranabuhanga Umunyamakuru wa buri munsi wabajije impuguke zireba.
Perovskite ntabwo calcium cyangwa titanium.
Ibyo bitaga na Parovskite ntabwo calcium cyangwa titanium, ahubwo ni ijambo rusange ryishuri rya "okide ya ceramic" ifite imiterere imwe ya kristu, hamwe na molecure ya molekale abx3. Igihagararo cya "Madius Kinini Cation", B kuri "cyuma cya" cyuma "na x kuri" anion delogen ". Urutonde rwa "Radius CATIUS CATIU", B igereranya "icyuma cya ctal" na x gihagaze kuri "anion delogen". Ibi bitatu birashobora kwerekana ibintu byinshi bitangaje bitangaje binyuze muburyo butandukanye cyangwa muguhindura intera iri hagati yabo, harimo no kutagarukira gusa kugirango ushizwemo, Ferroerdricity, Ingaruka nini nini, nibindi.
"Dukurikije ibigize ibikoresho by'ibanze ibikoresho, Perovskite bigabanywa mu byiciro bitatu: icyuma cy'icyuma gikomeye Perovskites, Orbic Hybrid Perovskites, na Onorganic Halogetents." Luo Jingshan, umwarimu ku ishuri rya Nankai rya Nankai amakuru ya kaminuza ya elegitoronike na injeniyeri ya optique, yamenyesheje ko Calcium Titanite yakoreshejwe muri PhotoVelleTics ni ebyiri za nyuma.
Perovskite irashobora gukoreshwa mubice byinshi nkibimera byingufu, aeropace, kubaka, hamwe nibisagaramakaza. Muri bo, umurima wa PhotoVoltaic nicyo gipimo nyamukuru cya Perovskite. Inzego za Titanite zirasobanutse cyane kandi zifite imikorere myiza ya PhotoVoltaic, nikintu cyubushakashatsi buzwi cyane mubushakashatsi mumwanya wa PhotoVoltaic mumyaka yashize.
Inganda za Perovski zirahita, kandi imigenzo yo murugo ihatanira imiterere. Biravugwa ko ibice 5.000 byambere bya Calcium titanium ore module yoherejwe kuva kumanuka ya hangzhou fina ifoto ya mafototolectric tekinoroji co., Ltd; Renshuo Photovolletaic (Suzhou) Co, Ltd nayo yihutisha kubaka ubunini bwa MW 150 yuzuye Calcium ya Milcium ya Dalianium. Kunshan GCL Ibikoresho bya Phofeterictric CO. Ltd MW 150 mw titanium ore Umurongo wa Matil
Calcium titanium ore ifite akamaro kagaragara mu nganda za Photovoltaic
Mu nganda za Photovoltaic, PerovsKite yabaye ishyushye mumyaka yashize. Impamvu yagaragaye ko ari "ukunda" mumirima yizuba biterwa nubuzima bwihariye.
"Ubwa mbere, PerovsKite ifite imitungo myinshi nziza, nk'itsinda rifite rishoboka, rihurira cyane, shitingi humura ingufu, kugenda cyane, kwihanganira impfabusa, nibindi .; Icya kabiri, inzira yo gutegura perovski iraryoroshye kandi irashobora kugera kuri translucency, ultra-trese-yoroheje, nibindi bikoresho bya perovski birahari cyane kandi ni byinshi. " Luo Jingshan yatangijwe. Kandi imyiteguro ya Perovski irasaba kandi isuku yo hasi yibikoresho fatizo.
Kugeza ubu, umurima wa PV ukoresha umubare munini w'ingirabuzimafatizo z'izuba zishingiye kuri silicon, zishobora kugabanywamo monocrystalline silicon, Polycrystalline Silicon, na Allic Shelicon Slarm. Igipfukisho cya Photorectlic yangiza inkingi ya Crystalline ya Silicon ya Silicon ni 29.4%, kandi ibidukikije byo muri laboratoire biriho birashobora kugera ku ya 26.7%, ari hafi cyane yo guhinduka; Ntabwo bigerwaho ko inyungu zamahoro ziterambere ryikoranabuhanga nazo zizaba nto kandi nto. Ibinyuranye n'ibyo, ihinduka rya PhotoVoltaic imikorere ya selile ya Perovski ifite agaciro ka miliyoni 33%, kandi niba selile ebyiri za Perovski zishyizwe hejuru no hasi hamwe, uburyo bwo guhindura imikorere bushobora kugera kuri 45%.
Usibye "gukora neza", ikindi kintu cyingenzi ni "Igiciro". Kurugero, impamvu ituma ikiguzi cyigisekuru cya mbere cya bateri ya firime zidashobora kumanuka nuko ububiko bwa cadmium na Gallium, ni bito, ni ibisubizo, niko, niko urundi ruhuteje. ni, icyangombwa kinini, kirenze urugero, kandi nticyigeze gishobora kuba ibicuruzwa nyamukuru. Ibikoresho fatizo bya Perovski bitangwa ku isi byinshi, kandi igiciro nacyo gihenze cyane.
Byongeye kandi, umubyimba wa calcium-titanium ahitwa calcium-titanium yamamazane na Nanometero magana make gusa, hafi 1/59 yiya kabiri ya wanors, bivuze ko ibyifuzo bya silicon, bivuze ko icyifuzo cyibikoresho ari gito cyane. Kurugero, ibisabwa kwisi yose yibikoresho bya silicon kuri selile ya Crystalline ni toni 500.000 kumwaka, kandi niba byose byasimbuwe na selile za Perovski, toni zigera ku 1.000 gusa za Perovskite.
Mu buryo bw'ibiciro byo gukora, akagari ka silicon kanseri ya silicon harasukurwa kuri 99.9999%, bityo silicon igomba gushyuha kuri dogere 1400. kugeza iminsi itatu hagati, hamwe no gukoresha imbaraga nyinshi. Ibinyuranye, kugirango umusaruro wa jerovskite, birakenewe gusa gushyira mu bikorwa amazi ya perovskite kuri substrate hanyuma utegereze ko Crystallisation. Inzira yose irimo ikirahure gusa, film ifatika, perovskite nibikoresho bya shimi, kandi birashobora kuzuzwa muruganda rumwe, kandi inzira yose ifata iminota 45 gusa.
Ati: "Imirasire y'izuba yateguwe muri PerovsKite ifite amashusho meza, yageze kuri iki cyiciro, kandi arashobora gusimbuza selile z'izuba muri Silicon muri Silicon ishingiye ku bucuruzi." Luo Jingshan yavuze.
Hano haribibazo bitatu byingenzi bigomba gukemurwa kugirango biteze imbere Inganda
Mugutezimbere inganda za chalcocite, abantu baracyakeneye gukemura ibibazo 3, ni ukuvuga ituze rya chalcocite, imyiteguro nini yuburyo nubusa.
Ubwa mbere, Perovskite yumva cyane ibidukikije, kandi ibintu nkubushyuhe, ubushyuhe, umucyo, numutwaro wumuzunguruko birashobora gutuma perovskite na kugabanya imikorere ya selile no kugabanya imikorere ya selile. Kugeza ubu laboratory nyinshi za larovskite ntabwo yujuje ubuziranenge mpuzamahanga bwa IEC 61215 kubicuruzwa byatotolika, ntanubwo bigera ku mwaka wa 10-20 ubuzima bwa silicon, bityo ikiguzi cya Perovski kiracyafite akamaro mu murima gakondo. Byongeye kandi, uburyo bwo gukwirakwiza bwa Perovski kandi ibikoresho byayo buragoye cyane, kandi nta gusobanukirwa neza inzira mu murima, cyangwa nta bushobozi buke, bukabuza gukora ubushakashatsi buhamye.
Ikindi kibazo gikomeye nuburyo bwo kubategurira kurwego runini. Kugeza ubu, mugihe ibikoresho byogutegura ibikoresho bikorerwa muri laboratoire, ahantu hafite urumuri rwibikoresho byakoreshejwe mubisanzwe bitarenze cm2, kandi mugihe cyo gusaba ubucuruzi bwibigize, uburyo bwo gutegura laboratoire bugomba kunozwa cyangwa gusimburwa. Uburyo nyamukuru bukoreshwa mugutegura firime nini za Perovskite nuburyo bwo kumusubiza hamwe nuburyo bwo guhumeka vacuum. Mu buryo bwo gukemura, kwibanda no gukusanya igisubizo cya mbere, ubwoko bwa solive, hamwe nigihe cyububiko bigira ingaruka zikomeye kumubare wa firime za Perovskite. Uburyo bwo guhumeka vacuum butegura ubuziranenge bwiza kandi bugenzurwa na firime za Perovskite, ariko birashoboka ko bigoye kugera kumibonano neza hagati yabanzaga no gusimburwa. Byongeye kandi, kubera ko igipimo cyo gutwara ibikoresho bya Perovskite nacyo gikeneye kwitegura mu gace kanini, umurongo utanga umusaruro hamwe na buri gice gikeneye gushingwa mu musaruro w'inganda. Muri rusange, inzira yo gutegura ibintu byinshi-byo gutegura firime za Perovskite ziracyakeneye kurushaho kugira intego.
Hanyuma, uburozi bwuburozi ni ikibazo cyo guhangayika. Mugihe cyo gusaza ibikoresho byo kurwana byikigereranyo bya Perovskite, Perovskite azabora kubyara ions yubusa na ions, bizaba byateje ubuzima, bikaba bishobora guteza imbere ubuzima nibamara kwinjira mumubiri wumuntu.
Luo Jingshan yemera ko ibibazo nko gushikama bishobora gukemurwa nibipfunyika ibikoresho. "Niba ejo hazaza, ibi bibazo byombi byakemuwe, hariho kandi inzira yo guteganwa ikuze, irashobora kandi gukora ibikoresho bya perovskite mu kirahure cyo gukuraho cyangwa gukora hejuru yinyubako, cyangwa bikozwe mubwishingizi bwa popurwe, cyangwa bikozwe mubikoresho byoroheje bya Aerospace na Izindi nzego, kugirango Perovskite mumwanya udafite amazi na ogisijeni kugirango ugire uruhare runini. " Luo Jingshan yizeye ejo hazaza h'uburi bwa Perovskite.
