Cov kws tshawb fawb ntawm US National Renewable Energy Laboratory tau nthuav tawm cov qauv ua haujlwm ntawm cov iav qhov rais ntse uas ua kom tsaus ntuj thaum raug tshav ntuj thiab pib tsim hluav taws xob ntawm cov ntaub ntawv ua haujlwm ntau dua 11%. Lawv nyuam qhuav piav txog lawv qhov kev tsim khoom hauv phau ntawv xov xwm Nature Communications.

Thermochromic iav, raws li cov khoom no hu ua, yog tus cwj pwm los ntawm lub peev xwm los hloov pauv pob tshab raws li kev cuam tshuam ntawm tshav kub los ntawm qhov teeb meem hnub ci. Cov thev naus laus zis no tau paub ntau xyoo, tab sis tsuas yog tam sim no nws muaj peev xwm tsim cov khoom siv uas siv qhov tshwm sim no los tsim hluav taws xob nrog kev ua haujlwm siab.

Cov iav ntse siv nws txoj haujlwm ntawm cov khoom siv thev naus laus zis xws li perovskites, uas tau nrov mus txog rau tam sim no. Nyob rau hauv qhov kev txiav txim ntawm lub hnub ci, ib tug reversible transformation ntawm lub complex ntawm halogen derivative ntawm perovskite thiab methylamine tshwm sim, uas ua rau discoloration ntawm iav.

NREL tsim lub qhov rais hloov tau hnub ci

Hmoov tsis zoo, tom qab kwv yees li 20 lub voj voog, qhov ua tau zoo ntawm tag nrho cov txheej txheem txo qis vim qhov hloov tsis tau hloov hauv cov qauv ntawm cov khoom. Lwm txoj haujlwm rau cov kws tshawb fawb yuav yog txhawm rau txhim kho kev ruaj ntseg thiab txuas ntxiv lub neej ntawm cov iav ntse.

Lub qhov rais ua los ntawm cov iav no ua haujlwm nyob rau hauv ob txoj hauv kev - nyob rau hnub tshav ntuj lawv tsim hluav taws xob thiab txo nws cov kev siv cua txias, vim lawv ib txhij txo qhov kub hauv lub tsev. Nyob rau hauv lub neej yav tom ntej, qhov kev daws teeb meem no tuaj yeem txhim kho lub zog sib npaug ntawm ob lub tsev ua haujlwm thiab cov tsev nyob.
