Munkhani ya Photovovoltalic, Perovskite yakhala ikutha kwa zaka zaposachedwa. Cholinga chomwe chimatuluka monga "zomwe amakonda" m'munda wa maselo a solar ndi chifukwa cha mikhalidwe yake yapadera. Calcium Titanium Ore ili ndi zithunzi zambiri zabwino za zithunzi, njira yosavuta yokonzekera, komanso zida zophatikizika ndi zochulukirapo. Kuphatikiza apo, perovskite imathanso kugwiritsidwanso ntchito mu mphamvu yamagetsi yamvula, kuyendetsa ndege, zomanga, zolimbitsa thupi m'mibadwo yambiri.
Pa Marichi 21, nthawi zina za nivede amafunsira patene ya "calcium Titanite Slar ndi njira yake yokonzekera ndi chida champhamvu". M'zaka zaposachedwa, mothandizidwa ndi malingaliro apanyumba ndi njira za calcium-calcium-titanium ore, woimiliridwa ndi caltanium ore dzuwa dzuwa, lapita kumayendedwe akulu. Ndiye ndi chiyani perovskite? Kodi kukwera kwa Perovskite kumatanthauza bwanji? Ndi mavuto ati omwe akukumana nawo? Science ndi ukadaulo wa ukadaulo wa tsiku lililonse adafunsa ophunzira oyenerera.
Perovskite si calcium kapena titanium.
Wotchedwa Perovskites sakhala calcium kapena titanium, koma nthawi yomweyo osungira "ndi mawonekedwe a kwofala, omwe ali ndi mawonekedwe a abx3. Kuyimira "kwakukulu kwa radius radius", b kwa "chitsulo" ndi x chifukwa cha "anion". Kuyimira "kwakukulu kwa radius", b amayima "chitsulo" ndi X amayima "halogen anyezi". Anu atatu awa amatha kukhala ndi zinthu zambiri zodabwitsa mwazinthu zosiyanasiyana kapena ndikusintha mtunda pakati pawo, kuphatikizapo koma osakhala ndi kutchinjiriza, kukhazikika kwa antifrorrromagnetim, granetic mphamvu, etc.
"Malinga ndi momwe zinthu ziliri, a Perovskites amatha kugawidwa m'magulu atatu: zovuta zamiyala oxide manrovskites, komanso ogwiritsanso mankhwala adafuwula perovskites." Luo Jiteshan, pulofesa yemwe amaphunzira ku yunivesite ya Nankiri University yazidziwitso zamagetsi ndi ukadaulo wamaso, adadziwitsa kuti Titanic Titites tsopano omwe amagwiritsidwa ntchito mu Photovoltaics nthawi zambiri amakhala awiri.
Perovskite ikhoza kugwiritsidwa ntchito m'minda yambiri monga mphamvu zapadziko lapansi zimamera, Aerospace, zomanga, ndi zida zolimbitsa thupi. Pakati pawo, chithunzi cha zithunzi ndi gawo lalikulu la perovskite. Makina a calcium titanite amakhala odziwika bwino ndipo ali ndi zithunzi zabwino kwambiri komanso zomwe ndi njira yofufuzira yofufuzira ku Photovovoltaic m'zaka zaposachedwa.
Kufalikira kwa Perovskite kukuthamangitsa, ndipo mabizinesi apakhomo akupikisana ndi kukomoka. Amanenedwa kuti zidutswa zoyambirira za calcium Ore Titanium ORE PATZYO PINEVELLELO POBEELOVELOVELRIC Tealoglogy Co., LTD; Renshuo Photvultac (Suzhou) co., Ltd. imathandiziranso kumanga 150 mw matanium titanium ore; Kunshan Gcl Plaseelectric zida za CO. ltd. 150 mw Phaccium-Titanium Ore Phocvoltaic Module Kupanga kwa Disembala 2022, ndipo mtengo wonena za pachaka umatha kufikira 300 miliyoni itatha kukwaniritsa.
Calcium Titanium Ore ili ndi zabwino zojambula patsamba la Photovovoltaltaltaltaltaltaltaltaltaltaltal
Munkhani ya Photovovoltalic, Perovskite yakhala ikutha kwa zaka zaposachedwa. Chifukwa chomwe chimachokera monga "zomwe amakonda" m'munda wa maselo a solar zimachitika chifukwa chokhala ndi zinthu zina.
"Choyamba, perovskite ali ndi mitundu yambiri ya optuelectronic, monga kuyamwa kwa band, yotsika kwambiri, kunyamula katundu wambiri, kulekereratu, etc.; Kachiwiri, kukonzekera njira ya perovskite ndikosavuta ndipo kumatha kuwonongeka, ma ultra-kuwonda, pomaliza, kusintha kwa ziweto za Perovski ndi zochulukirapo. " Luo akumayambitsa. Ndipo kukonzekera kwa Perovskite kumafunanso kuyera kotsika kwambiri kwa zinthu zosaphika.
Pakadali pano, munda wa PV umagwiritsa ntchito maselo akuluakulu a silicon, omwe amatha kugawidwa munocrystalline silicon, pelycrystalne silicon, ndi ma cell a amorphous dzuwa. Chitetezero chojambula cha thereeelectric poleclecton crystan cell ndi 29.4%, ndipo malo omwe aburamu pano amatha kufikira 26,7%, omwe ali pafupi kwambiri ndi denga la kutembenuka mtima; Zikuwonekeratu kuti phindu la kusintha kwaukadaulo lidzakhala laling'ono komanso laling'ono. Mosiyana ndi izi, chithunzi cha zithunzi za Photovoltaic mu ma cell a Perovskite chili ndi mtengo wambiri wa 3%, ndipo ngati maselo awiri a perovskite akhazikika pansi, njira yothetsera bwino kwambiri.
Kuphatikiza pa "luso", chinthu china chofunikira kwambiri ndi "mtengo". Mwachitsanzo, chifukwa chake mtengo wa mabatire wa makanema owonda sangatsike ndi kuti malo osungirako Cadmium ndi galulla, omwe ndi osowa kwambiri padziko lapansi, ndipo chifukwa cha ntchitoyo Ndiye chifukwa chake, zomwe amafuna kwambiri, mtengo wapamwamba wopanga, ndipo sunakhalepo chinthu chimodzi. Zopangira za perovskite zimagawidwa pamiyeso yambiri padziko lapansi, ndipo mtengo wake umatsika mtengo kwambiri.
Kuphatikiza apo, makulidwe a calcium - titanium oretium over calcium - titanium oreter ndi ma nanometer okha, pafupifupi 1/500 ya a Silicon Wafers, zomwe zikutanthauza kuti kufunikira kwa zinthuzo ndikochepa kwambiri. Mwachitsanzo, kufunidwa kwapadziko lonse kwa Silicon zinthu za maselo a kristalo ndi matani pafupifupi 500,000 pachaka, ndipo ngati onsewo asinthidwa ndi maselo 1,000 okha ndi Perovskite.
Pankhani yopanga mtengo, maselo a Crystalline amafunikira kuyeretsa silicon mpaka 99.999%, kotero siyicon, ophatikizidwa ndi ma celsius Celsius, wophatikizidwa kukhala ma celsius celsius, ndikuphatikizidwa ndi mafakitale anayi ndi awiri mpaka masiku atatu pakati, ndipo amagwiritsa ntchito mphamvu zambiri. Mosiyana ndi izi, popanga maselo a perovskite, ndikofunikira kugwiritsa ntchito zigawo za perovskite bii mpaka gawo lapansi ndikudikirira Crystallization. Njira yonse imaphatikizira galasi, yomatirani filimu, perovskite ndi zida zamankhwala, ndipo zimatha kumaliza ntchito imodzi, ndipo njira yonse imangotenga pafupifupi mphindi 45.
"Ma cell a dzuwa omwe amakonzedwa kuchokera ku Perovskite ali ndi zojambula bwino zojambula zithunzi, zomwe zafika pa 25.7% pa siteji iyi, ndipo itha kusintha ma cell a silicon mtsogolo kuti akhale malonda." Luo Jiteshan ananena.
Pali mavuto atatu akulu omwe amafunikira kuti athetsere kukonza mafakitale
Popititsa patsogolo kufalikira kwa Chalcocite, anthu amafunikirabe kuthetsa mavuto atatu, ndiko kukhazikika kwa nthawi yayitali kwa Chalcocite, kukonzekera kwakukulu kwa malo ndi kuwongolera kwa chitsogozo.
Choyamba, perovskite imakhudzidwa kwambiri ndi chilengedwe, komanso zinthu monga kutentha, chinyezi, chopepuka, komanso chopepuka, chimatha kuwonongeka kwa ma cell. Pakadali pano module ya labovskite perovskite sakumana ndi IEC 61215 International Standard Offs, ndipo safika pa moyo wa zaka 10-20 wa ma cell, kotero mtengo wa perovskite suli wopindulitsa mu Photovolkiic munda. Kuphatikiza apo, chipongwe cha pa Perovskite ndi zida zake ndizovuta kwambiri, ndipo palibe kumvetsetsa kowonekera kwa njira yomwe ili m'mundamo, komanso palibe muyeso wogwirizana, womwe umawononga kafukufuku wokhazikika.
Nkhani ina yayikulu ndi momwe angakonzekere pamlingo waukulu. Pakadali pano, pomwe maphunziro otsitsa a chipangizocho amachitidwa mu labotale, malo owala othandiza a zida omwe amagwiritsidwa ntchito nthawi zambiri amakhala osakwana 1 cm2, ndipo zikafika pa malonda a zinthu zazikulu, njira zokonzekera labotale zimafunikira kusintha kapena m'malo. Njira zazikuluzikulu zomwe zikugwiritsidwa ntchito pokonzekera mafilimu akuluakulu a Perovskite ndi njira yothetsera njira komanso njira yochepetsera. Mu njira yothetsera, kuchuluka kwa kusiyana kwa njira yothetsera, mtundu wa zosungunulira, ndipo nthawi yosungirako imakhudzanso mafilimu a perovskite. Njira ya vacuum, imakonzekeretsa bwino mafilimu a Perovskite, koma zimakhalanso zovuta kukwaniritsa kulumikizana bwino pakati pa zikwangwani. Kuphatikiza apo, chifukwa maofesi a zonyamula a Perovskite chipangizo chimafunikiranso kukonzedwa m'dera lalikulu, mzere wopangidwa ndi kupezeka kopitilira muyeso aliyense ayenera kukhazikitsidwa mu mafakitale. Ponseponse, njira yokonzekera kudera lalikulu la Perovskite ikusowa kungoyambira.
Pomaliza, chiwopsezo chotsogolera chimakhalanso ndi vuto lokhudza nkhawa. Pakapita kukalamba lazinthu zapamwamba kwambiri za Perovskite zidalipo, perovski adzawola kuti apange anyezi waulere ndikutsogolera monomemers, zomwe zingakhale zoopsa thanzi pomwe amalowa m'thupi la munthu.
Luo Jingen amakhulupirira kuti mavuto monga kukhazikika angathetsedwe ndi zomwe zikuchitika. "Ngati m'tsogolo mwake, mavutowa awiriwa athetsedwa, palinso njira yokonzekera a Perovskite mu startlucnt Minda ina, kotero kuti perovski mu danga popanda malo osungira madzi ndi oxygen kuti azigwira ntchito yayikulu. " Luo jishan ali ndi chidaliro pa zamtsogolo za perovskite.
