Kugwiritsa Ntchito Zinthu Zosowa Padziko Lapansi Kuti Mugonjetse Zochepa za Maselo a Dzuwa
gwero:AZO zipangizoMaselo a Solar a PerovskiteMaselo a dzuwa a Perovskite ali ndi ubwino kuposa zamakono zamakono zamakono zamakono. Iwo ali ndi kuthekera kochita bwino kwambiri, ndi opepuka, komanso otsika mtengo kuposa mitundu ina. Mu selo la dzuwa la perovskite, gawo la perovskite limayikidwa pakati pa electrode yowonekera kutsogolo ndi electrode yowonetsera kumbuyo kwa selo.Zoyendera za elekitirodi ndi zigawo zoyendera dzenje zimayikidwa pakati pa cathode ndi anode interfaces, zomwe zimathandizira kusonkhanitsa ndalama pamagetsi.Pali magawo anayi a ma cell a solar a perovskite kutengera kapangidwe ka morphology ndi kutsatizana kwa magawo oyendetsa: okhazikika, ma planar opindika, ma mesoporous okhazikika, komanso mawonekedwe opindika a mesoporous.Komabe, pali zovuta zingapo ndiukadaulo. Kuwala, chinyezi, ndi okosijeni zimatha kuyambitsa kuwonongeka kwawo, kuyamwa kwawo kumatha kufananizidwa, komanso amakhala ndi zovuta pakuphatikizanso kopanda ma radiation. Perovskites imatha kuwonongedwa ndi ma electrolyte amadzimadzi, zomwe zimapangitsa kuti pakhale bata.Kuti akwaniritse ntchito zawo zothandiza, kuwongolera kuyenera kupangidwa pakusintha mphamvu zawo moyenera komanso kukhazikika kwa magwiridwe antchito. Komabe, kupita patsogolo kwaposachedwa kwaukadaulo kwapangitsa kuti ma cell a solar a perovskite akhale ndi mphamvu ya 25.5%, zomwe zikutanthauza kuti sali kutali ndi maselo owoneka bwino a silicon photovoltaic solar.Kuti izi zitheke, zinthu zapadziko lapansi zosowa zafufuzidwa kuti zigwiritsidwe ntchito m'maselo a dzuwa a perovskite. Iwo ali ndi zithunzithunzi zomwe zimagonjetsa mavuto. Kugwiritsa ntchito ma cell a solar a perovskite kumapangitsa kuti zinthu zawo ziziyenda bwino, zomwe zimapangitsa kuti zikhale zogwira mtima kwambiri pakukhazikitsa njira zazikulu zothetsera mphamvu zamagetsi.Momwe Zosowa Zapadziko Zimathandizira Ma cell a Solar a PerovskitePali zinthu zambiri zopindulitsa zomwe zinthu zapadziko lapansi zosowa zili nazo zomwe zitha kugwiritsidwa ntchito kukonza magwiridwe antchito a m'badwo watsopanowu wa ma cell a solar. Choyamba, makutidwe ndi okosijeni ndi kuchepetsa kuthekera kwa ma ion apadziko lapansi osowa amatha kusinthika, kumachepetsa makutidwe ndi okosijeni a zinthu zomwe akufuna komanso kuchepetsa. Kuonjezera apo, mapangidwe a filimu yopyapyala amatha kuyendetsedwa ndi kuwonjezeredwa kwa zinthu izi poziphatikiza ndi perovskites ndi zitsulo zoyendetsa zitsulo.Kuphatikiza apo, mawonekedwe a gawo ndi mawonekedwe a optoelectronic amatha kusinthidwa powalowetsa m'malo mwa crystal lattice. Chilema chingathe kukwaniritsidwa mwa kuziyika muzinthu zomwe mukufuna kuziyika mozungulira malire a tirigu kapena pamwamba pa zinthuzo.Kuphatikiza apo, ma infrared ndi ma ultraviolet photon amatha kusinthidwa kukhala kuwala kowoneka bwino kwa perovskite chifukwa cha kukhalapo kwa njira zambiri zosinthira zamphamvu mu ma ion apadziko lapansi osowa.Ubwino wa izi ndi ziwiri: zimapewa ma perovskites kuti awonongeke ndi kuwala kwamphamvu kwambiri ndikuwonjezera mawonekedwe amtundu wazinthu. Kugwiritsa ntchito zinthu zapadziko lapansi zomwe zimasowa kumapangitsa kuti pakhale bata komanso mphamvu zama cell a solar a perovskite.Kusintha Ma Morphologies a Mafilimu OchepaMonga tanenera kale, zinthu zapadziko lapansi zosowa zimatha kusintha ma morphology amafilimu oonda okhala ndi oxides zitsulo. Zimatsimikiziridwa bwino kuti morphology yazitsulo zoyendetsera zoyendetsa zowonongeka zimakhudza maonekedwe a perovskite wosanjikiza ndi kukhudzana kwake ndi gawo loyendetsa galimoto.Mwachitsanzo, doping yokhala ndi ma ion osowa padziko lapansi imalepheretsa kuphatikizika kwa SnO2 nanoparticles komwe kungayambitse zolakwika zamapangidwe, komanso kumachepetsa kupanga makristalo akuluakulu a NiOx, kupanga yunifolomu ndi wosanjikiza wa makhiristo. Choncho, mafilimu woonda wosanjikiza wa zinthu zimenezi popanda chilema angapezeke ndi osowa-padziko lapansi doping.Kuphatikiza apo, scaffold wosanjikiza m'maselo a perovskite omwe ali ndi mawonekedwe a mesoporous amatenga gawo lofunikira pakulumikizana pakati pa perovskite ndi zigawo zonyamula katundu m'maselo a dzuwa. Ma nanoparticles muzinthu izi amatha kuwonetsa zolakwika za morphological ndi malire ambiri ambewu.Izi zimabweretsa kuyambiranso koyipa komanso kowopsa kopanda ma radiation. Kudzaza pore kulinso vuto. Doping yokhala ndi ma ion osowa padziko lapansi imayang'anira kukula kwa scaffold ndikuchepetsa zolakwika, kupanga ma nanostructures ogwirizana komanso ofanana.Popereka kusintha kwa mapangidwe a morphological a perovskite ndi zigawo zoyendetsera zolipiritsa, ma ions osowa padziko lapansi amatha kupititsa patsogolo magwiridwe antchito komanso kukhazikika kwa ma cell a solar a perovskite, kuwapangitsa kukhala oyenera kugulitsa malonda akuluakulu.TsogoloKufunika kwa ma cell a dzuwa a perovskite sikungatheke. Apereka mphamvu zopangira mphamvu zapamwamba pamtengo wotsika kwambiri kuposa ma cell a solar apano a silicon pamsika. Kafukufuku wasonyeza kuti doping perovskite yokhala ndi ayoni osowa padziko lapansi imapangitsa kuti zinthu zake ziziyenda bwino, zomwe zimapangitsa kuti pakhale kukhazikika komanso kukhazikika. Izi zikutanthauza kuti ma cell a dzuwa a perovskite omwe ali ndi magwiridwe antchito abwino ndi gawo limodzi loyandikira kuti likwaniritsidwe.
