Calcium titanium oxide nyob sab hauv tsev photovoltaic modules nrog kev hloov pauv tau zoo tshaj 36 feem pua
Dec 23, 2022
Tsis ntev los no, xib fwb Mai Yaohua pab neeg ntawm lub koom haum ntawm Tshiab Zog Technology ntawm Jinan University tau txais ib tug ywj siab thib peb daim ntawv pov thawj ntawm ntau tshaj 36 feem pua conversion efficiency rau loj-chav kawm ntawv calcium titanite nyob rau hauv tsev photovoltaic modules, tus nqi siab tshaj tshaj qhia nyob rau hauv lub ntiaj teb no kom deb li deb. Cov txiaj ntsig kev tshawb fawb cuam tshuam tau luam tawm hauv Advanced Science.
Lub hnub ci tshuab thev naus laus zis siv chalcogenide raws li lub teeb absorbing txheej tau txais kev mloog ntau hauv xyoo tas los. Kev siv cov cell photovoltaic rau sab hauv tsev tsis tshua muaj lub teeb hluav taws xob sau tau dav siv hauv kev lag luam IoT, ntse hauv tsev thiab kev siv lub ntsej muag ntse, tab sis lawv yuav tsum muaj qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv kom ua tiav kev hloov pauv siab. Lub optical band qhov sib txawv ntawm chalcogenide lub teeb absorbing txheej tuaj yeem hloov kho ntau yam, ua kom tau txais kev hloov pauv siab ntawm cov khoom siv hluav taws xob photovoltaic, thiab cov pab pawg tau tshaj tawm sab hauv tsev chalcogenide photovoltaic hlwb nrog kev ua tau zoo tshaj li 40 feem pua.
Txawm li cas los xij, cov ntsiab lus siab bromine (Br) nyob rau hauv dav bandgap chalcogenide zaj duab xis tuaj yeem yooj yim ua rau cov xwm txheej sib cais thiab cuam tshuam rau kev ua haujlwm ntawm cov cuab yeej. Pab neeg Mai Yaohua tau tshawb xyuas qhov kev sib raug zoo ntawm bandgap thiab kev ua haujlwm sab hauv tsev photovoltaic ntawm chalcogenide photovoltaic cells thiab pom tias, ntxiv rau kev sib cais theem, Br qhov tsis xws luag hauv chalcogenide photoabsorption txheej yog ib qho ntawm cov ntsiab lus tseem ceeb txwv qhov qhib hluav taws xob hluav taws xob ntawm lub hlwb. Kev kho mob nrog iodine(I)-nplua nuj alkali hlau me me molecule cov ntaub ntawv zoo daws qhov teeb meem Br vacancy thiab txhim kho kev hloov pauv ntawm cov cuab yeej hauv qab lub teeb qis. Nyob rau hauv TL84 lub teeb qhov chaw ntawm 1000 lux, sab hauv photovoltaic module nrog thaj tsam zoo ntawm 12.30 cm2 tau txais kev hloov dua siab tshiab ntawm 36.36 feem pua tau lees paub los ntawm lwm tus neeg sab nrauv, qhov kev tshaj tawm kev hloov pauv siab tshaj plaws ntawm calcium titanite low light module hauv ntiaj teb.
Nyob rau tib lub sijhawm, pab pawg tau tsim qauv qauv sab hauv tsev lub teeb lub zog sau qoob loo raws li chalcogenide PV module, uas ua tiav cov khoom siv hluav taws xob sab hauv tsev, qhov siab tshaj plaws lub zog taw tes, kev tswj fais fab thiab roj teeb, ambient kub thiab av noo sau, Bluetooth kev sib txuas lus thiab tsis muaj- them nqi. Tsis tas li ntawd, pab pawg tau sau tseg tias qhov kev ntsuam xyuas qhov tseeb ntawm sab hauv PV cell kev ua tau zoo thiab kev ua qauv ntawm cov txheej txheem kuaj yog qhov tseem ceeb rau kev lag luam ntawm cov thev naus laus zis.
