Kuyakhawulezisa ukwakhiwa kweyona ndawo iphambili yehlabathi ye-calcium epheleleyo; I-Kunshan GCL yeFowuni CCL ye-CO.
I-calcium titanium ore inezinto ezibonakalayo kwishishini lefotovoltaic
Kumzi-mveliso wefotovoltaic, iPerovskite ibikwimfuno eshushu kwiminyaka yakutshanje. Isizathu sokuba ivele njenge "into oyithandayo" kwicandelo leeseli zelanga zinemigaqo yayo ekhethekileyo.
"Ekuqaleni, uPerovskite unezindlu ezininzi ezilungileyo ze-pitoecteect, ezinje ngebhendi eguqukayo, i-action ephezulu ye-coanden, i-coander enamachaphaza e-coading, ukuthwala okuphezulu, ukunyamezelana okuphezulu, njl.; Okwesibini, inkqubo yokulungiselela ye-Perovskite ilula kwaye inokuphumeza uTransluence, ukukhanya kwe-Ultra-Muliness, izinto eziguquguqukayo zifumaneka, njl. " ULuo Goinghan. Kwaye amalungiselelo ePerovskite afuna ukucoceka okusezantsi kwezinto ezingaphantsi.
Okwangoku, intsimi ye-PV isebenzisa inani elikhulu leeseli ze-silicon-esekwe kwi-monocrystalline, i-polycrystalline, kunye ne-amorphos silicon yelensico. I-Theoretic Pole yefoto ye-crystalline ye-Crystalline sells i-29.4%, kunye nendawo yangoku yelebhu inokufikelela kwinqanaba lama-26.7%, elisondele kakhulu kwi-phaling; Kuyabonwa kwangaphambili ukuba inzuzo engapheliyo yokuphuculwa kwetekhnoloji iya kuba incinci kwaye incinci. Ngokwahlukileyo, ukusebenza kwefotovoltaic ye-Perovskite ze-Perovskite zexabiso eliphezulu le-33%, kwaye ukuba iiseli ezimbini ze-Perovskite ziye zangena kunye, ukusebenza kwethiyori kuya kufikelela kwiipesenti ezingama-44.
Ukongeza "ekusebenzeni kakuhle", enye into ebalulekileyo yi "Ixabiso". Umzekelo, isizathu sokuba iindleko zesizukulwana sokuqala seebhetri zefilimu azinakuze zize kwenzeke kukuba i-Cadmium ne-Galliyoyo, ezincinci, kwaye ngenxa yoko, kokukhona uphuhliso oluphuhlileyo Ngaba, kokukhona kubalulekileyo kwimfuno, ukuphakama kwemveliso, kwaye akuzange kube nako ukuba yimveliso ephambili. Izinto ezingafunekiyo zePerovskite zisasazwa kwizixa ezikhulu emhlabeni, kwaye ixabiso lingabizi kakhulu.
Ukongeza, ubukhulu be-calcium-i-titanium ore ye-calcium-titanium ore iibhetri ngamakhulu nje kuphela, malunga ne-1 / 500th yeyo lebango le-silicon, elithetha ukuba imfuno ye-silicon incinci kakhulu. Umzekelo, imfuno yangoku yehlabathi yezinto ze-silicon kwizilwanyana zeCrystaline imalunga neetoni ezingama-500,000 ngonyaka, kwaye ukuba zonke zitshintshwe iiseli ezili-1 000 zePerovskite.
Ngokweendleko zemveliso, iiseli ze-Crystalline zifuna ukuhlanjululwa kwe-silicon kwi-99.999%, ke inyibilikiswe i-rods, inyibilikiswe kwiiseli ezijikelezayo, kunye neefeksi ezine kunye nezazi ezine ukuya kwiintsuku ezintathu phakathi, kunye nokusebenzisa amandla amakhulu. Ngokwahlukileyo, ukuveliswa kweeseli ze-Perovskite, kuyimfuneko kuphela ukusebenzisa i-Perovskite yesiseko se-perovskite yesiseko kwisiseko se-sublest kwaye silinde i-crystallization. Inkqubo iyonke ibandakanya kuphela iglasi, ifilimu yobumbeko, i-perovskite kunye nezinto zemichiza, kwaye zinokugqitywa kumzi-mveliso omnye, kwaye yonke inkqubo ithatha kuphela malunga nemizuzu engama-45.
"Iiseli zelanga ezilungiselelwe kwiPerovskite ineendlela ezifanelekileyo zokuguqula ifoto, ezifikileyo kwi-25.7% ngeli nqanaba, kwaye zinokutshintsha iiseli zelanga ezisekwe kwixesha elizayo kwikamva ukuba libe yindawo yezorhwebo." ULuo žingshan utshilo.
Zintathu iingxaki eziphambili ezifuna ukusonjululwa ukukhuthaza ukwahlulwa kwezemali
Ekuqhubeleni phambili kwezomzi-mveliso weChalcocite, abantu basafuna ukusombulula iingxaki ezi-3, oko kukuthi, ukuzinza kwexesha elide kweChalcocite, ukulungiselela indawo enkulu kunye netyhefu.
Okokuqala, uPerovskite uthambekele kakhulu kwindalo, kunye nezinto ezifana nobushushu, umswakama, ukukhanya, kunye nomthwalo wesekethe kunokukhokelela ekunciphiseni kwe-perovskite kunye nokuncitshiswa kokusebenza kakuhle kweseli. Okwangoku uninzi lweemodyuli ze-Porovskite azifikeleli kumgangatho we-IEC 61215 yeHlabathi yeeMveliso zeFotovoltaic, kwaye zifikelela kunyaka we-10 ukuya kwe-40 zeRhafu yeSlicon Sohafu, ke iindleko ze-Perovskite azisasebenzi kwintsimi ye-photovoltaic yemveli. Ukongeza, indlela yokonakaliswa kwe-Perovskite kwaye izixhobo zayo zintsonkothe kakhulu, kwaye akukho kuqonda ngokucacileyo ngenkqubo entsimini, kwaye akukho nqanaba lidibeneyo lophando.
Omnye umba ophambili yindlela yokuzilungiselela kwinqanaba elikhulu. Okwangoku, xa izifundo zokwenza isixhobo zenziwa kwilabhoratri, indawo elula yecandelo elisetyenzisiweyo ihlala ingaphantsi kwe-1 cm2, kwaye xa isiza kwinqanaba lesicelo sezinto ezinkulu, iindlela zokulungiselela amalabhori kufuneka ziphuculwe okanye ukutshintshwa. Iindlela eziphambili ezisetyenziswayo ngoku ukulungiselela iifilimu ezinkulu ze-Perovskite yindlela yesisombululo kunye nendlela yokuphuma kwamava. Kwindlela yesisombululo, uxinzelelo kunye nomyinge wesisombululo sangaphambili, uhlobo lwesiselo, kwaye ixesha lokugcina linempembelelo enkulu kumgangatho weefilimu zePerovskite. Indlela yokuphelelwa ngumgangatho ilungiselela umgangatho olungileyo kunye nokulawulwa kweefilimu ze-Perovskite, kodwa kubunzima ukufezekisa unxibelelwano oluhle phakathi kwe-precurs kunye neminye. Ukongeza, ngenxa yokuba umtywala wezothutho wesixhobo sePerovskite kufuneka ulungiselelwe indawo enkulu, umgca wemveliso onokufunyanwa okuqhubekayo kwesimiselo ngasinye kufuneka usekwe kwimveliso yemveliso. Ngokubanzi, inkqubo yokulungiselela indawo enkulu ye-Perovskite Iifilimu ezincinci zisafuna ukwenziwa kolunye.
Okokugqibela, ityhefu yokukhokela ikwangumba oxhalabisayo. Ngexesha lokukhula kwenkqubo yokuphelisa i-perovskite ye-Perovskite ye-Perovskite, iPerovskite iya kubola ukuvelisa ii-Ions zasimahla kunye ne-monomers, eya kuba yingozi kwimpilo xa sele ingena emzimbeni.
ULuo Jingshan ukholelwa ukuba iingxaki ezinjengokuzinza zingasonjululwa ngokupakishwa kwesixhobo. "Ukuba kwixa elizayo, ezi ngxaki zimbini zisonjululwe, kukwakhona izixhobo zokulungiselela i-perovskite kwiglasi ye-Perovsiction okanye yenza kumphezulu wezakhiwo zokuphumeza i-thovoltaic ukudityaniswa kweefoto, okanye zenziwe kwizixhobo eziguquguqukayo ze-aerospace kwaye Amanye amasimi, ukuze iPerovskite kwindawo engenamanzi kunye nendawo ye-oxhlagen ukuze idlale eyona ndima iphakamileyo. " ULuo jingshan uyaqiniseka ngekamva likaPerovskite.
