Cov kws tshawb nrhiav los ntawm Kaus Lim Qab Teb Kauslim Ulsan National Institute of Science thiab Technology (UNIST) tau tshaj tawm txog kev hloov pauv hloov 25.17% hauv ibperovskite xovtooj ntawm hnub ci, ua tiav los ntawm kev ua haujlwm tsawg tshaj plaws rau kev rhuav tshem rau microstructure ntawm cov txheej txheem ua ke hauv cov khoom.
Pab pawg neeg piav qhia tias microstructure ntawm cov khaubncaws sab nraud povtseg no, uas tsim hluav taws xob thiab xa mus rau hluav taws xob, tuaj yeem deformed - uas cuam tshuam rau kev ua haujlwm ntawm lub txim hloov ntawm nws tus kheej. Lawv piav tias "Nov yog vim tias cov nqi hluav taws xob rho tawm thaum cov tsis xws luag tau tsim lawm,"
Cov kws tshawb nrhiav tau hais tias lawv ua tiav rau kev txo qis sab hauv qhov tsis xws ntawm cov txheej txheem ua yeeb yaj kiab los ntawm kev hloov hom thiab kev sib piv ntawm ions tau muab tso rau hauv cov khaubncaws sab nraud povtseg. Cov kev hloov no tau ua lub luag haujlwm ntxiv rau lub hnub ci cell' s hluav taws xob qhib hluav taws xob, "Cov khoom siv raug kaw 90% ntawm cov pib ua haujlwm tom qab 400 xuaj moos ntawm lub zog loj kawg ntawm kev ua haujlwm," cov kws tshawb fawb tau hais, ntxiv tias cov ntawv pov thawj efficiency ntawm lub cuab yeej yog 24.4%.
Pab pawg neeg Kaus Lim tseem hais ntxiv tias lub xov tooj ntawm tes tswj tau ntau dua 80% ntawm nws cov thawj zaug tom qab 1,300 teev thaum tsaus ntuj ntawm 85 degrees Celsius.
