Ib pab neeg tshawb fawb European tau tshawb xyuas qhov cuam tshuam ntawm cov xuab zeb thiab plua plav paug ntawm photovoltaic modules hauv Oman. Lawv tau sau 60 tus qauv hauv lub caij sib txawv, lub hli thiab lub kaum sab xis.
Cov kws tshawb fawb los ntawm Imperial College London thiab Karlsruhe Institute of Technology tau tshawb xyuas qhov cuam tshuam ntawm cov xuab zeb thiab plua plav paug ntawm cov iav ntawm lub hnub ci modules hauv Oman. Ib nrab ntawm Oman yog suab puam.
Lawv tau kawm txog qhov cuam tshuam ntawm cov xuab zeb thiab plua plav paug ntawm cov khoom siv kho qhov muag thiab hluav taws xob ua haujlwm ntawm photovoltaic panels. Txoj kev tshawb no tus kws sau ntawv Christos Markides tau hais rau cov neeg sau xov xwm: "Peb kuj tau tshawb xyuas kev lag luam ntawm cov pa phem hauv plua plav, tab sis nws tseem tsis tau luam tawm. Cov txiaj ntsig tau pom tias kev poob nyiaj txiag yog nyob ntawm qhov chaw tshwj xeeb."
Txoj kev tshawb no yog ua raws li 60 cov qauv sau los ntawm qhov chaw kho dej phwj hauv Muscat, lub nroog Oman.
Daim ntawv hais tias: "Kev kwv yees lub zog tsim hluav taws xob ntawm kev teeb tsa photovoltaic tiag tiag tseem nyuaj vim tias cov plua plav paug paug tuaj yeem raug tshaj / qis dua. Cov plua plav paug pov tseg yog nyob ntawm qhov loj me, cov duab thiab cov spectra, uas tuaj yeem cuam tshuam loj rau kev ua haujlwm ntawm photovoltaic. panels. Nyob rau hauv daim ntawv no peb nthuav tawm cov txiaj ntsig ntawm kev sim sab nraum zoov kev sib tw tawm tsam kev sib kis ntawm cov xuab zeb thiab plua plav, siv cov txheej txheem ntxaws ntxaws thaum saib xyuas cov txiaj ntsig uas tshwm sim. "
Nyob rau hauv daim ntawv, "Tus cwj pwm ntawm iav nto fouling thiab nws cov kev cuam tshuam rau optical thiab hnub ci photovoltaic kev ua tau zoo," tsis ntev los no luam tawm nyob rau hauv phau ntawv journal Renewable Energy, Markides thiab cov npoj yaig piav qhia tias cov qauv kuaj tau tsim los ntawm Ua los ntawm cov iav hlau hlau. Nyob rau hauv kev lag luam hnub ci, cov daim coupon no feem ntau yog siv los encapsulate sab saum toj txheej ntawm photovoltaic modules. Lawv khaws cov qauv iav thaum kawg ntawm txhua lub hli hauv 2021, qhov txawv ntawm lub caij los nag thiab lub caij qhuav. Thaum txhua lub sijhawm sau, cov kws tshawb fawb tau sau plaub qhov qauv ntawm lub kaum sab xis ntawm 0, 23, 45 thiab 90 degrees.
Tom qab ntawd lawv tau xa cov qauv mus rau London rau kev kuaj pom lub teeb. Kev tshuaj xyuas qhia tau hais tias cov txheeb ze sib kis ntawm cov qauv kab rov tav txo los ntawm 65% hauv lub caij los nag, 68% nyob rau lub caij qhuav thiab 64% thoob plaws xyoo.
Pab neeg tshawb fawb ntxiv tias: "Hauv kev sib piv, qhov sib piv ntawm cov khoom ntsuas ntsug tau txo qis los ntawm 34%, 19% thiab 31% feem. cov ces kaum Tus txheeb ze kis tau tus mob yog txo los ntawm 44%, 49% thiab 42% feem.
Raws li cov txiaj ntsig no, cov kws tshawb fawb tau suav qhov kev cia siab ntawm lub zog poob ntawm monocrystalline PV modules raws li cov qauv ntsuas, uas yog lub zog siv hluav taws xob ntawm 1000 W / m2 thiab qhov kub ntawm 25 degrees Celsius.
Lawv tau hais ntxiv tias: "Cov txheeb ze sib kis tau txo qis ntsuas siv lub caij ntub dej, lub caij qhuav thiab cov qauv kab rov tav xyoo puag ncig sib haum mus rau 67%, 70% thiab 66% ntawm cov kwv yees kwv yees txo qis hauv kev tsim hluav taws xob, raws li kev kwv yees ntawm lub kaum sab xis hauv zos ntawm 23. degrees, txhua hli Tus txheeb ze kev xa tawm poob yog kwv yees li 30%, uas ua rau kwv yees li 30% txo qis hauv qhov sib npaug ntawm cov txheeb ze photovoltaic zog ntawm qhov chaw kawm txhua lub hlis. "
Cov kws tshawb fawb tom qab ntawd siv X-ray thiab electron microscopy los soj ntsuam cov yam ntxwv ntawm cov av. Txij li thaum tag nrho cov qauv iav tau coj los ntawm tib qhov chaw, cov kws tshawb fawb xav tias lawv cov av muaj cov yam ntxwv zoo ib yam. Yog li ntawd, lawv tsuas yog txheeb xyuas cov iav kab rov tav thaum lub caij ntub thiab qhuav thiab xyoo puag ncig.
Lawv tau hais ntxiv tias: "X-ray diffraction (XRD) cov txiaj ntsig tau qhia tias cov xuab zeb thiab plua plav pov tseg txhua xyoo muaj ntau yam minerals, xws li silica, calcium carbonate, calcium magnesium carbonate, titanium dioxide, hlau carbide thiab aluminium silicate. Cov ntsiab lus faib daim duab qhia txog cov ntsiab lus qhia los ntawm XRD tsom xam.Qhov tseem ceeb tshaj plaws yog silicon (Si), cov khoom seem muaj xws li carbon (C), oxygen (O), sodium (Na), magnesium (Mg), aluminium (Al), calcium (Ca) thiab hlau (Fe).
Cov kws tshawb fawb tseem pom tau tias cov qauv ntawm lub caij qhuav muaj PM10 ntau dua li cov qauv caij ntuj nag. PM10 yog qhov nqus tau cov teeb meem tsawg dua 10 microns hauv txoj kab uas hla. "Txoj kev tshawb fawb tseem qhia tau tias cov dej nag ib ntus tuaj yeem tshem tawm cov khoom loj, tab sis tsis yog cov khoom me me," lawv piav qhia hauv daim ntawv.
