Txawm hais tias lub hnub ci vaj huam sib luag cia siab rau lub hnub ci los tsim hluav taws xob, cua sov tuaj yeem txo qhov kev ua haujlwm ntawm lub hnub ci.Ib pab pawg kws tshawb fawb los ntawm Kaus Lim Qab Teb tau pom cov tshuaj xav tsis thoob: roj ntses.
Txhawm rau tiv thaiv lub hnub ci los ntawm overheating, cov kws tshawb fawb tau tsim cov txheej txheem photovoltaic thermal uas siv cov kua los lim cov cua sov thiab lub teeb.Los ntawm kev tshem tawm cov teeb ci ultraviolet uas tuaj yeem ua kom sov lub hnub ci, cov lim dej tuaj yeem ua kom lub hnub ci txias thaum khaws cov cua sov rau tom qab siv.
Decoupled photovoltaic thermal systems ib txwm siv dej los yog nanoparticle daws raws li cov kua lim dej.Qhov teeb meem yog tias dej thiab nanoparticle daws tsis lim ultraviolet rays zoo heev.
"Decoupled photovoltaic thermal systems siv cov kua lim dej kom nqus cov tsis muaj txiaj ntsig zoo xws li ultraviolet, pom thiab ze-infrared rays.Txawm li cas los xij, dej, lim dej nrov, tsis tuaj yeem nqus cov kab hluav taws xob ultraviolet zoo, txwv tsis pub lub cev ua haujlwm, "- Kauslim Maritime University (KMOU).Ib pab neeg tshawb fawb los ntawm CleanTechnica piav qhia.
Pab pawg KMOU pom tias cov roj ntses zoo heev ntawm kev lim tawm lub teeb ntau dhau.Thaum feem ntau cov dej-raws li decoupling systems ua hauj lwm ntawm 79.3% efficiency, cov ntses roj-raws li system tsim los ntawm KMOU pab neeg ua tiav 84.4% efficiency.Rau kev sib piv, pab pawg tau ntsuas lub hnub ci ntawm lub hnub ci kev ua haujlwm ntawm 18% kev ua haujlwm thiab lub hnub ci hluav taws xob sab nraud ntawm 70.9% kev ua haujlwm.
"[Ntses roj] emulsion lim tau zoo nqus ultraviolet, pom thiab ze-infrared wavelengths uas tsis ua rau lub zog tsim hluav taws xob ntawm photovoltaic modules thiab hloov mus rau hauv thermal zog," pab pawg neeg daim ntawv tshaj tawm hais.
Decoupled photovoltaic thermal tshuab tuaj yeem muab cov cua sov thiab hluav taws xob."Cov txheej txheem npaj tuaj yeem ua haujlwm raws li qee qhov kev xav tau thiab ib puag ncig ib puag ncig.Piv txwv li, nyob rau lub caij ntuj sov, cov kua hauv cov kua lim dej tuaj yeem hla dhau los ua kom muaj hluav taws xob ntau tshaj plaws, thiab lub caij ntuj no, cov kua lim dej tuaj yeem ntes cov cua sov rau cua sov, "KMOU pab pawg qhia.
Raws li kev thov rau lub zog tauj dua tshiab, cov kws tshawb fawb tau ua haujlwm tsis tu ncua los ua kom lub hnub ci hluav taws xob pheej yig dua, ruaj khov thiab ua haujlwm tau zoo.Rugged perovskite solar cells muaj txiaj ntsig zoo thiab pheej yig, thiab silicon nanoparticles tuaj yeem hloov lub teeb hluav taws xob qis rau lub teeb muaj zog.Pab pawg KMOU qhov kev tshawb pom sawv cev rau lwm kauj ruam tom ntej hauv kev ua kom muaj zog siv hluav taws xob pheej yig dua.
Sau npe rau peb tsab ntawv xov xwm pub dawb kom tau txais kev hloov tshiab txhua lub lim tiam ntawm qhov kev hloov kho tshiab tshaj plaws uas txhim kho peb lub neej thiab txuag lub ntiaj teb.
