Embonini ye-Photovoltaic, iPelovskite ibilokhu isidingo esishisayo eminyakeni yamuva. Isizathu esenza ukuthi sivele njenge- "intandokazi" emkhakheni wama-solar cell kungenxa yezimo zayo ezihlukile. I-calcium titanium ore inezindawo eziningi ezinhle kakhulu ze-photovoltaic, inqubo elula yokulungiselela, kanye nohlu olubanzi lwezinto zokusetshenziswa ezivuthiwe nokuqukethwe okuningi. Ngaphezu kwalokho, i-Perovskite nayo ingasetshenziswa ezitshalweni zamandla ezinkundla, izindiza, zokwakha, amadivaysi okuphehla amandla okugula namanye amasimu amaningi.
NgoMashi 21, isikhathi saseNingde sifaka isicelo selungelo lobunikazi be- "calcium titanite solar cell kanye nendlela yalo yokulungiselela nedivayisi yamandla". Eminyakeni yamuva nje, ngokwesekwa kwezinqubomgomo ezifuywayo nezinyathelo, imboni ye-calcium-titanium ore, emelelwa yi-calcium-titanium ore solar cell, yenze izithuthukisi ezinkulu. Manje yini iPhrovskite? Kunjani ukuthuthuka kwePelovskite? Yiziphi izinselelo ezisabhekene? Isayensi neTekhnoloji Intatheli yansuku zonke yaxoxa nochwepheshe abafanele.
I-Perovskite akuyona i-calcium noma i-titanium.
Ama-perovski abizwa nge-calcium noma i-titanium, kepha igama elijwayelekile lesigaba se- "Ceramic oxides" ngesakhiwo esifanayo se-crystal, ngefomula kalako abx3. Isimo se- "radius radius cation", B "ye-Metal Cation" no-X ye- "Halogen Anion". Isimo se- "Great Radius Cation", B simele "i-Metal Cation" kanye no-X bemelela "Halogen Anion". Lawa ma-ion amathathu angakhombisa izakhiwo eziningi ezibonakalayo ezingokomzimba ngokuhlelwa kwezinto ezahlukene noma ngokulungisa ibanga phakathi kwazo, kufaka phakathi ukufakwa, i-Ferroeelectricity, i-antiferromagnetism, njll.
"Ngokusho kokwakheka kwalezi zinto ezibonakalayo, ama-perovskites angahlukaniswa ngezigaba ezintathu: ama-perovskites ayinkimbinkimbi ama-oxide we-ongide, ama-perovskites e-organic hrovskites, kanye nama-perovskites e-inorganic. ULuo Jingshan, uprofesa e-Nankai University's School of Excy Universical of Electronic kanye nobunjiniyela be-Optical, wethule ukuthi ama-Titanites e-calcium manje asetshenziswa manje e-Photovoltaics imvamisa okubili.
I-Perovskite ingasetshenziswa emikhakheni eminingi efana nezitshalo zamandla asemhlabeni, ama-aerospace, namadivayisi okuphehla amandla okuphehla amandla. Phakathi kwazo, i-Photovoltaic field yindawo eyinhloko yesicelo sePelovskite. Izakhiwo ze-calcium titanite ziqashelwe kakhulu futhi zinokusebenza okuhle kwe-photovoltaic, okuyindlela ethandwayo yokucwaninga enkundleni ye-Photovoltaic eminyakeni yamuva.
Ukuthuthukiswa kwezimboni kwePerovskite kuyashesha, futhi amabhizinisi asekhaya ancintisana nokwakheka. Kubikwa ukuthi izingcezu zokuqala ezingama-5 000 zamamojula we-calcium titanium ore athunyelwe kusuka ku-Hangzhou Fina Photoelectric Technology Co, Ltd; I-RESHUO Photovoltaic (Suzhou) Co, Ltd futhi isheshisa ukwakhiwa kwe-calcium enkulu ka-150 mW Full Full Full Calcium Titanium Ore Lamiadied Line Line; Umugqa we-Kunshan Gcl Photeleelcric Umugqa we-150 MW Calcium-Titanium Ore Photovoltaic Moduen
I-calcium titanium ore inezinzuzo ezisobala embonini ye-Photovoltaic
Embonini ye-Photovoltaic, iPelovskite ibilokhu isidingo esishisayo eminyakeni yamuva. Isizathu esenza ukuthi sivele njenge- "intandokazi" emkhakheni wama-solar cell kungenxa yezimo zayo ezihlukile.
"Okokuqala, iPelovskite inezindawo eziningi ezinhle kakhulu ze-Optoelectronic, njenge-band band gag eguqukayo, i-couffient evumayo, amandla aphansi okubopha, ukubekezelelana okuphezulu, ukubekezelelana okuphezulu, njll; Okwesibili, inqubo yokulungiselela ye-Perovskite ilula futhi ingafinyelela ukuguquguquka, ukukhanya kwe-Ultra-ukukhanya, ukuguquguquka, izinto zokwakha i-njll. Ekugcineni, izinto ze-Purovskite eziluhlaza zitholakala kabanzi futhi ziningi. " Kuthulwa uLuo JingShan. Futhi ukulungiswa kwe-perovskite kudinga nobumsulwa obuphansi bezinto eziluhlaza.
Njengamanje, inkambu ye-PV isebenzisa inani elikhulu lamaseli elanga asuselwa elongeni lesilo, elingahlukaniswa nge-monocrystalline silico, i-polycrystallineline silico, nama-amorphon silicon solar cell. Isigxobo se-theoretical PhotoElectric Soccersic Cells sama-Crystalline Silicon Cell singama-29.4%, kanti indawo yelebhu yamanje ingafinyelela inani elingama-26.7%, elisondele kakhulu ophahleni lokuguqulwa; Kuyabonakala ukuthi ukuzuzwa kokungezwani kokuthuthuka kwezobuchwepheshe nakho kuzoba kuncane futhi kube mncane. Ngokuphambene nalokho, ukusebenza kahle kwe-Photovoltaic kwama-perovskite cell kunenani eliphakeme le-theoretical pole lama-33%, futhi uma amaseli amabili eProvskite afakwe phezulu, ukusebenza kahle kwe-theoretical ukuguqulwa kungafinyelela ku-45%.
Ngaphezu "ukusebenza kahle", enye into ebalulekile "izindleko". Isibonelo, isizathu esenza ukuthi izindleko zesizukulwane sokuqala samabhethri amafilimu amancane angeke zehlile ukuthi izinqolobane zeCadmium ne-Gallium, eziyincithakalo kakhulu emhlabeni, zincane kakhulu, futhi ngenxa yalokho, kwathuthukiswa kakhulu imboni yemboni , kukhula okukhulu, kukhuphuka izindleko zokukhiqiza, futhi akukaze ukwazile ukuba umkhiqizo ojwayelekile. Izinto ezivuthiwe zasePerovskite zisatshalaliswa ngamanani amakhulu emhlabeni, futhi intengo nayo ishibhile kakhulu.
Ngaphezu kwalokho, ubukhulu bokubopha amabhethri e-calcium-titanium ore kuma-nanometer angamakhulu ambalwa kuphela, cishe ngo-1/500 walokho kwama-silicon wafers, okusho ukuthi isidingo salokho okuba sincane kakhulu. Isibonelo, isidingo samanje somhlaba wonke se-Silicon Material Amaseli we-Crystalline Silicon cishe amathani angama-500,000 ngonyaka, futhi uma konke kuthathelwa indawo amaseli weProvskite, kuphela amathani we-Purovskite azodingeka.
Ngokuya kwezindleko zokukhiqiza, amaseli we-crystalline silicon adinga ukuhlanzwa kwe-silicon ku-99.9999%, ngakho-ke i-silicon kumele ifudunyezwe ama-degrees angama-1400, ancibilikiswe ezintabeni eziyindilinga, bese eqopha amafeyili, okungenani ahlanganiswe amafektri amane ezinsukwini ezintathu phakathi, ukusetshenziswa okukhulu kwamandla. Ngokuphambene nalokho, ukukhiqizwa kwamaseli we-perovskite, kudingekile kuphela ukufaka i-perovskite base liquid ku-substrate bese ulinda i-crystallization. Inqubo yonke ifaka kuphela ingilazi, ifilimu, ifilimu, i-perovskite kanye nezinto zokwakha amakhemikhali, futhi ingaqedwa efektri eyodwa, futhi yonke inqubo ithatha cishe imizuzu engama-45.
"Amangqamuzana elanga alungiselelwe ePelovskite anokusebenza kahle kwe-Photolectric okungcono kakhulu, okufinyelele ku-25.7% kulesi sigaba, futhi kungathatha isikhundla samangqamuzana elanga asesibili esolaka esikhathini esizayo ukuze abe yindawo yokuhweba." ULuo Jingshan uthe.
Kunezinkinga ezintathu ezinkulu ezidinga ukuxazululwa ukukhuthaza ukuthuthukiswa kwezimboni
Lapho kuthuthukiswa ukuthuthukiswa kwezimboni zeChalcocite, abantu basadinga ukuxazulula izinkinga ezi-3, okungukuthi ukuqina kwesikhathi eside kwe-chalcocite, ukulungiswa kwendawo enkulu kanye nobuthi bokuhola.
Okokuqala, i-Perovskite inaka kakhulu imvelo, futhi izici ezinjengokushisa, umswakama, ukukhanya, nomthwalo wesekethe kungaholela ekuboleni kwe-perovskite kanye nokwehliswa kokusebenza kweselula. Njengamanje amamojula we-perovskite we-labovskite welabhoratri awahlangabezani ne-IEC 61215 International Standard yemikhiqizo ye-Photovoltaic, futhi ayifinyeleli esikhathini sokuphila kwe-Silicon Solar, ngakho-ke izindleko ze-Perovskite azisenanzuzo kwinkambu ye-Photovoltaic yendabuko. Ngaphezu kwalokho, indlela yokucekelwa phansi ye-perovskite kanye namadivayisi awo iyinkimbinkimbi kakhulu, futhi akukho ukuqonda okucacile kwenqubo enkundleni, futhi akukho okujwayelekile okulinganiselwe, okulimazayo ekucwaningweni kokuqina.
Enye inkinga enkulu ukuthi ungabalungiselela kanjani ngezinga elikhulu. Njengamanje, lapho kwenziwa izifundo zokusebenza kwensiza ngelebhu, indawo yokukhanya esebenzayo yamadivayisi asetshenzisiwe ingaphansi kwe-1 cm2, futhi uma kukhulunywa ngesigaba sohlelo lokusebenza lwentengiso yezinto ezinkulu, izindlela zokulungiselela iLabhoratri zidinga ukwenziwa ngcono noma ungene esikhundleni. Izindlela eziphambili ezisebenza njengamanje ukulungiswa kwamafilimu amakhulu we-Purovskite ayindlela yesisombululo kanye nendlela yokuhwamuka kwe-vacuum. Ngendlela yesixazululo, okuhlushwa kanye nokulinganiswa kwesisombululo sangaphambi kwesakhiwo, uhlobo lwe-solvent, nesikhathi sesitoreji sinomthelela omuhle kwikhwalithi yamafilimu e-perovskite. Indlela ye-Vacuum EkAPornioration ilungiselela ukufakwa okuhle nokulawulwa kwamafilimu we-Purovskite, kepha kunzima futhi ukufezekisa ukuxhumana okuhle phakathi kwama-Preserron kanye nama-substrates. Ngaphezu kwalokho, ngoba ungqimba we-Cluriction Transport of the Perovskite futhi udinga ukulungiswa endaweni enkulu, umugqa wokukhiqiza onokuqhubeka kokukhiqizwa kwesendlalelo ngasinye kudinga ukusungulwa ekukhiqizweni kwezimboni. Sekukonke, inqubo yokulungiswa kwendawo enkulu yamafilimu amancane eProvskite asadinga ukwenziwa okwengeziwe.
Ekugcineni, ubuthi bokuhola buyinkinga yokukhathazeka. Ngesikhathi senqubo yokuguga yamadivayisi aphezulu ePerovskite asebenza kahle, i-Purovskite izovela ukukhiqiza ukuhola ama-ions mahhala futhi iholele amamomers, okuzoba yingozi impilo uma sebengene emzimbeni womuntu uma sebengene emzimbeni womuntu uma sebengene emzimbeni womuntu uma sebengene emzimbeni womuntu uma sebengene emzimbeni womuntu uma sebengene emzimbeni womuntu uma sebengene emzimbeni womuntu uma sebengene emzimbeni womuntu uma sebengene emzimbeni womuntu uma sebengene emzimbeni womuntu uma sebengene emzimbeni womuntu uma sebengene emzimbeni womuntu uma sebengena emzimbeni womuntu uma sebengene emzimbeni womuntu uma sebengene emzimbeni womuntu uma sebengene emzimbeni womuntu uma sebengena emzimbeni womuntu uma sebengena emzimbeni womuntu uma sebengena emzimbeni womuntu uma sebengene emzimbeni womuntu.
ULuo Jingshan ukholelwa ukuthi izinkinga ezinjengokuqina zingaxazululwa ngokupakishwa kwedivayisi. "Uma ngokuzayo, lezi zinkinga ezimbili zixazululwa, futhi kunenqubo yokulungiselela evuthiwe, futhi kungenza futhi amadivaysi ePerovskite abe yi-Translucent Glass noma enziwe ngamadivaysi aguqukayo e-aerospace futhi Eminye imikhakha, ngakho-ke i-perovskite esikhaleni ngaphandle kwemvelo yamanzi ne-oksijini ukuze udlale indima enkulu. " ULuo Jingshan uyazethemba ngekusasa lasePelovskite.
