Key Takeaways
- Cov kws tshawb fawb hauv tebchaws Australia tau tsim lub hnub ci tshwj xeeb semi-pob tshab.
- Nws ua haujlwm tsawg dua li cov hnub ci vaj huam sib luag tab sis cia lub teeb txaus los siv ua lub qhov rais.
- Cov kws tshawb fawb xav txhim kho cov pob tshab hluav taws xob tsim lub qhov rais hauv skyscrapers uas feem ntau tsis muaj qhov chaw ru tsev rau cov hnub ci vaj huam sib luag.
Cov kws tshawb fawb tau tsim cov kev daws teeb meem tshiab los hloov cov qhov muag hauv nroog mus rau hauv lub tshuab hluav taws xob huv.
Ib pab pawg ntawm Australian cov kws tshawb fawb tau tsim ib lub hnub ci pob tshab uas lawv xav tau ib hnub tso cai rau cov skyscrapers los tsim lawv lub zog. Lub hnub ci pob tshab yog tsim los ntawm perovskite hlwb, uas feem ntau hailed raws li lub neej yav tom ntej ntawm solar cells.
"Kev ua haujlwm no muab cov kauj ruam tseem ceeb rau pem hauv ntej ntawm kev ua kom muaj txiaj ntsig zoo thiab ruaj khov perovskite cov cuab yeej uas tuaj yeem siv tau raws li lub hnub ci qhov rais kom ua tiav qhov uas tsis muaj kev lag luam loj heev," xibfwb Jacek Jasieniak los ntawm Department of Materials Science & Engineering ntawm Monash University, tau hais hauv tsev kawm ntawv xov xwm.

Crystalline silicon tau mus rau kev xaiv rau kev tsim lub hnub ci vaj huam sib luag rau ntau xyoo lawm. Cov kws tshawb fawb, txawm li cas los xij, tau nrhiav lwm txoj hauv kev, feem ntau vim yog cov txheej txheem kim thiab siv zog ntawm kev tsim cov silicon-based solar panels.
Perovskite lub hnub ci hnub ci tau tshwm sim los ua ib qho kev cog lus. Perovskite tau txais nws lub npe rau nws cov qauv siv lead ua tshwj xeeb. Tus kws tshawb fawb German Gustav Rose tau tshawb pom nws hauv xyoo 1839. Perovskites yooj yim rau kev sib txuas, thiab lawv cov qauv tshwj xeeb ua rau lawv muaj txiaj ntsig zoo li photovoltaics (PV) rau hloov lub hnub ci rau hauv lub zog.
Tsim los ntawm qhov no, pab pawg ntawm cov kws tshawb fawb los ntawm ARC Center of Excellence hauv Exciton Science coj los ntawm xibfwb Jasieniak tau tsim cov hlwb perovskite nrog kev hloov pauv ntawm 15.5 feem pua, thaum tso cai ntau dua 20 feem pua ntawm cov teeb pom kev los ntawm. Txhawm rau muab qhov no tso rau hauv qhov kev xav, ru tsev silicon hlwb feem ntau muaj qhov ua tau zoo li ntawm 20 feem pua.
Nyob rau xyoo 2020, tib pab pawg ntawm cov kws tshawb fawb tau tsim cov pob tshab perovskite hnub ci nrog 17 feem pua ntawm kev hloov pauv hluav taws xob thiab tuaj yeem tso 10 feem pua ntawm cov teeb pom kev los ntawm.
Thaum lub zog hloov pauv kev ua haujlwm hauv qhov kev tshawb fawb tshiab kawg yog ob peb qhov qis dua li pab pawg cov txiaj ntsig yav dhau los, qhov pom ntawm lub teeb pom kev tshiab tso cai rau hla tau ob npaug. Cov kws tshawb fawb tau sib cav tias qhov no yuav ua rau lawv muaj peev xwm siv tau ntau yam ntawm cov ntawv thov tiag tiag hauv ntiaj teb.
"[Lub hnub ci pob tshab semi-pob tshab] tau ua rau muaj kev cuam tshuam tseem ceeb hauv kev lag luam hauv tsev-kev sib koom ua ke photovoltaic (BIPV), vim tias lawv tau nce ntau thaj chaw uas muaj peev xwm siv tau los tsim hluav taws xob hauv nroog ib puag ncig," ceeb toom cov kws tshawb fawb. "Tsis tas li ntawd, lawv kuj muaj qhov zoo ntawm kev txo qhov xwm txheej kub nce mus rau hauv cov tsev los ntawm ib nrab nqus thiab xav txog hnub ci."
Ib kauj ruam ze dua
Lwm qhov kev txhim kho hauv perovskite hnub ci hlwb tsim los ua ib feem ntawm qhov kev tshawb fawb tshiab yog qhov ruaj khov mus ntev thaum kuaj rau kev teeb pom kev tsis tu ncua thiab cua sov, uas cov kws tshawb fawb xav ua raws li cov xwm txheej uas cov khoom yuav ntsib hauv kev siv tiag tiag.
Lub tsev tsis yog tam sim no tsim kom haum rau lub zog tsim cov facades.
"Lub hauv paus kev tshawb fawb ua haujlwm, thiab lub tswv yim zoo heev, tshwj xeeb tshaj yog rau cov tsev nrog cov iav loj loj thiab qhov chaw me me ntawm lub ru tsev muaj rau cov pa hluav taws xob silicon photovoltaics," Dr. James O'Shea, Associate Professor & Reader hauv Physics. Lub Tsev Kawm Ntawv ntawm Physics & Astronomy thiab University of Nottingham Energy Institute, hais rau Lifewire hauv email.
Lance Wheeler, tus kws tshawb fawb ua haujlwm ntawm National Renewable Energy Laboratory (NREL), kuj zoo siab rau kev txhim kho. "Qhov kev ua tau zoo thiab kev pom tseeb ntawm perovskite PV windows txuas ntxiv nce thiab tuaj yeem ua rau muaj kev cuam tshuam hauv ntiaj teb," Wheeler hais rau Lifewire ntawm email.
Txawm li cas los xij, Wheeler tau taw qhia tias ntau thaj chaw yuav tsum tau hais ntxiv rau kev ua haujlwm thiab kev pom tseeb ua ntej peb pom cov pob tshab PV qhov rai no tau siv dav dav.
Rau qhov pib, lawv yuav tsum tau ua cov xim zoo nkauj. Wheeler tau hais tias Perovskite hlwb yog daj, txiv kab ntxwv, lossis liab, thiab yuav tsum muaj txheej ntxiv los hloov cov xim mus rau nruab nrab greys lossis maj mam xiav thiab ntsuab, uas yog ntau tshaj plaws rau lub qhov rais.
Wheeler tseem lees paub tias thaum cov ntaub ntawv perovskite tau dhau los ntev ntawm kev ua haujlwm ntev, kev siv lub tsev sib xyaw tseem xav tau ntau dua li lub ru tsev lossis hluav taws xob hnub ci vim qhov tsis ua haujlwm thiab hloov pauv yog kim dua thiab cuam tshuam rau cov neeg nyob.
Dr. O'Shea tau hais tias perovskite lub hnub ci hnub ci tuaj yeem siv nyob rau hauv tandem nrog cov tsoos silicon los ua hybrid hlwb nrog ntau dua efficiency. Nws ntseeg siab tias txoj kev loj hlob ntawm lub hnub ci qhov rais yuav pab tsav kev loj hlob ntawm perovskite solar cell technology, ua rau lawv muaj kev saws me nyuam nyob rau hauv lub xyoo tom ntej.
"Lub tsev tsis tau tsim tam sim no kom haum rau lub zog-tsim facades," taw qhia Wheeler. "Yuav tsum muaj kev kawm thiab hloov mus rau kev tsim kho kev lag luam ua ntej qhov no tshwm sim ntawm qhov loj."
