Tsis ntev los no, Nagoya University hauv Nyij Pooj tau tsim cov thev naus laus zis uas tuaj yeem txuas lub neej ntawm "perovskite" photovoltaic cells, uas tuaj yeem kho tau thiab tuaj yeem tsim tau ntawm tus nqi qis, los ntawm 2 mus rau 4 zaug. Nws tuaj yeem txuas ntxiv mus txog 20 xyoo, nce mus txog qib piv rau cov xov tooj hluav taws xob photovoltaic ua los ntawm silicon. Lub tsev kawm ntawv yuav kawm txog kev tsim khoom nrog cov tuam txhab thiab sib zog ua kom tiav daim ntawv thov nyob rau hauv ib nrab xyoo 2020s. Qhov no yuav txhawb kev nrov ntawm lub cim tshiab ntawm cov cell photovoltaic uas yuav pab txo qis cov pa roj carbon monoxide.
Perovskite photovoltaic cells yog tsim los ntawm kev siv cov khoom zoo li txheej rau ntawm zaj duab xis thiab iav substrate. Nws tau hais tias tus nqi tsim khoom tuaj yeem txo qis rau ib nrab ntawm silicon photovoltaic hlwb. Yog hais tias ib zaj duab xis nyias heev yog siv rau ntawm lub substrate, qhov hnyav yuav tsum tau txo mus rau ib feem kaum.
