Qhov Kev Tshawb Fawb Kawg ntawm Photovoltaic Panels

Tam sim no, cov kws tshawb fawb tau ua haujlwm ntawm peb qhov tseem ceeb ntawm kev tshawb fawb photovoltaics: crystalline silicon, perovskites thiab hloov pauv hnub ci.Peb qhov chaw muaj kev sib txuas ntxiv rau ib leeg, thiab lawv muaj peev xwm ua kom cov tshuab photovoltaic muaj txiaj ntsig zoo dua.

Crystalline silicon yog cov khoom siv semiconducting feem ntau hauv cov hnub ci vaj huam sib luag.Txawm li cas los xij, nws cov txiaj ntsig tau qis dua qhov kev txwv theoretical.Yog li ntawd, cov kws tshawb fawb tau pib tsom mus rau kev tsim cov crystalline PVs siab heev.Lub National Renewable Energy Laboratory yog tam sim no tsom rau kev tsim cov khoom siv III-V multijunction uas xav tias yuav muaj kev ua tau zoo txog li 30%.

Perovskites yog ib yam tshiab ntawm lub hnub ci cell uas tsis ntev los no tau pom tias muaj txiaj ntsig zoo thiab muaj txiaj ntsig.Cov ntaub ntawv no tseem hu ua "photosynthetic complexes."Lawv tau siv los ua kom muaj txiaj ntsig ntawm cov hnub ci hlwb.Lawv cia siab tias yuav dhau los ua lag luam nyob rau ob peb xyoos tom ntej no.Piv rau silicon, perovskites kuj pheej yig thiab muaj ntau yam kev siv tau.

Perovskites tuaj yeem ua ke nrog cov ntaub ntawv silicon los tsim lub hnub ci zoo thiab ruaj khov.Perovskite crystal solar cells tuaj yeem ua tau 20 feem pua ​​​​ntau dua li silicon.Perovskite thiab Si-PV cov ntaub ntawv kuj tau qhia cov ntaub ntawv ua tau zoo txog li 28 feem pua.Tsis tas li ntawd, cov kws tshawb fawb tau tsim cov thev naus laus zis bifacial uas ua rau lub hnub ci lub hnub ci sau lub zog los ntawm ob sab ntawm lub vaj huam sib luag.Qhov no tshwj xeeb tshaj yog muaj txiaj ntsig zoo rau kev lag luam kev lag luam, vim nws txuag nyiaj ntawm cov nqi installation.

Ntxiv nrog rau perovskites, cov kws tshawb fawb tseem tab tom tshawb nrhiav cov ntaub ntawv uas tuaj yeem ua raws li cov neeg nqa khoom lossis lub teeb absorbers.Cov ntaub ntawv no tseem tuaj yeem pab ua kom lub hnub ci hluav taws xob ntau dua.Lawv kuj tuaj yeem pab tsim cov vaj huam sib luag uas tsis tshua muaj kev puas tsuaj.

Cov kws tshawb fawb tam sim no tab tom ua haujlwm tsim kom muaj txiaj ntsig zoo Tandem Perovskite hnub ci cell.Cov xovtooj ntawm no yuav tsum tau ua lag luam nyob rau ob peb xyoos tom ntej no.Cov kws tshawb fawb tau koom tes nrog US Department of Energy thiab National Science Foundation.

Tsis tas li ntawd, cov kws tshawb fawb tseem tab tom ua haujlwm tshiab ntawm kev sau cov hnub ci zog hauv qhov tsaus ntuj.Cov txheej txheem no suav nrog hnub ci distillation, uas siv cov cua sov los ntawm lub vaj huam sib luag los ntxuav dej.Cov txheej txheem no raug sim hauv Stanford University.

Cov kws tshawb fawb tseem tab tom tshawb nrhiav kev siv cov khoom siv thermoradiative PV.Cov khoom siv no siv cua sov los ntawm lub vaj huam sib luag los tsim hluav taws xob thaum hmo ntuj.Cov tshuab no tuaj yeem pab tau tshwj xeeb hauv cov huab cua txias uas cov vaj huam sib luag ua haujlwm tau txwv.Qhov kub ntawm lub hlwb tuaj yeem nce mus rau ntau dua 25degC ntawm lub ru tsev tsaus.Cov hlwb kuj tuaj yeem ua kom txias los ntawm dej, uas ua rau lawv zoo dua.

Cov kws tshawb fawb no kuj tsis ntev los no tau tshawb pom kev siv lub hnub ci hloov tau yooj yim.Cov panels no tuaj yeem tiv taus submersion hauv dej thiab yog qhov hnyav heev.Lawv kuj muaj peev xwm tiv taus kev khiav ntawm lub tsheb.Lawv cov kev tshawb fawb tau txhawb nqa los ntawm Eni-MIT Alliance Solar Frontiers Program.Lawv kuj tau tsim ib txoj kev tshiab ntawm kev sim PV hlwb.

Cov kev tshawb fawb tshiab tshaj plaws ntawm photovoltaic panels yog tsom rau kev tsim cov thev naus laus zis uas ua tau zoo dua, tsis tshua muaj nqi, thiab ruaj khov dua.Cov kev tshawb fawb no tau ua los ntawm ntau pab pawg hauv Tebchaws Meskas thiab thoob ntiaj teb.Cov thev naus laus zis zoo tshaj plaws suav nrog tiam thib ob tiam nyias-zaj duab xis hnub ci hlwb thiab hloov tau lub hnub ci hlwb.
