Chalcogenide-silicon tandem hnub ci hlwb tswj 80 feem pua ​​​​ntawm kev ua haujlwm tom qab ib xyoos

Cov kws tshawb fawb hauv Saudi Arabia tau hais tias lawv tau txhim kho sab nraum zoov kev ruaj ntseg ntawm calcium titanite-silicon tandem hnub ci hlwb los ntawm kev tsim nyog encapsulation. Thaum kawg ntawm thawj xyoo ntawm kev ua haujlwm, lub xov tooj ntawm tes qhov tseem ceeb tseem nyob saum 70 feem pua.

Chalcogenide-silicon tandem hnub ci hlwb

Cov kws tshawb fawb ntawm King Abdullah University of Science thiab Technology (KAUST) hauv Saudi Arabia tau ua qhov kev sim sab nraum zoov ib xyoos ntev ntawm calcium titanite-silicon tandem hnub ci cell uas lawv tab tom tsim hauv 2020. Lawv pom tias cov cuab yeej tswj tau ntau dua 80 feem pua ​​​​ntawm nws. Thawj qhov ua tau zoo thaum lub sijhawm sim txij lub Plaub Hlis 2021 txog Lub Plaub Hlis 2022.

"Peb tsis tau hais txog 500 lossis 1,000 teev nyob rau hauv ib puag ncig kev sim tswj, tab sis kev ntsuas sab nraum zoov tiag tiag nyob rau lub sijhawm ntev xyoo." Tus kws tshawb fawb Maxime Babics hais rau Photovoltaics magazine, sau tseg tias qhov kev sim no tsuas yog pib xwb. "Tam sim no qhov kev ua tau zoo ntawm lub hnub ci tandem hlwb tau dhau 30 feem pua, kuv xav tias nws yog lub sijhawm los tsom mus rau kev ruaj ntseg, thiab peb tab tom tsom mus rau lub neej tsawg kawg 20 xyoo."

Pab neeg no tsis ntev los no tau piav qhia lawv qhov kev tshawb pom hauv tsab xov xwm "Ib xyoos ntawm kev ua haujlwm sab nraum zoov ntawm ib qho chalcogenide / silicon tandem solar cell", luam tawm hauv phau ntawv xov xwm Cell Reported Matter Science. Lawv taw qhia tias cov encapsulation muaj zog yog qhov tseem ceeb los txo qis kev cuam tshuam txog kev ua tsis tiav.

Cov kws tshawb fawb no tau soldered ob lub xov hlau ntawm ob sab ntawm lub hnub ci cell kom txuas cov electrode pob qij txha. Tom qab ntawd lawv tau ntim cov cuab yeej ntawm ob txheej ntawm thermoplastic polyurethane (TPU) thiab iav ua ntej laminating lub rooj sib txoos.

Lawv teem lub hnub ci tandem ntawm lub kaum sab xis ntawm 25 degrees tig mus rau sab qab teb. Tom qab ntawd lawv tau sim lawv ntawm KAUST qhov chaw sim hauv Saudi Arabia ntawm lub ntiaj teb kab rov tav irradiance (GHI) ntawm ib ncig ntawm 2240 kWh / m2.

Cov kws tshawb fawb tau hais tias, "Kev sib xyaw ua ke ntawm high irradiance, siab kub thiab siab txheeb ze av noo ntawm qhov chaw sim tsim ib qho nyuaj rau cov calcium titanite solar cells thiab tseem muaj feem cuam tshuam rau kev kawm sab nraum zoov toughness ntawm photovoltaic technology."

Lub tandem installation qhov tseem ceeb tseem ceeb tshaj 78 feem pua ​​​​rau thawj plaub lub hlis thiab tom qab ntawd maj mam txo mus rau ib ncig ntawm 72 feem pua ​​​​ntawm Lub Yim Hli mus txog Lub Kaum Ob Hlis. Thaum kawg ntawm thawj xyoo ntawm kev ua haujlwm, tus nqi no tseem nyob siab dua 70 feem pua.

Cov kws tshawb fawb tau hais tias, "Raws li qhov ua tau zoo tshaj plaws yog qhov feem ntau yuav poob rau sab nraum zoov, cov txiaj ntsig zoo li no ua rau peb muaj kev ntseeg siab rau kev txhim kho kev ruaj ntseg ntawm cov thev naus laus zis series."

Lawv tau sau tseg tias lub xovtooj tseem yuav tuav tau ntau dua 80 feem pua ​​​​ntawm nws qhov kev ua tau zoo pib thaum lub Plaub Hlis 2021.

Babics tau hais tias, "Qhov no txhais tau tias peb tau ua kom muaj kev vam meej nyob rau sab nraum zoov, tab sis nws yog qhov tseeb tias peb muaj chaw rau kev txhim kho. Nws tseem ceeb heev uas yuav tsum nco ntsoov tias cov roj teeb tandem no tau tsim nyob rau hauv peb lub chaw sim thaum kawg ntawm 2020, thiab kuv tuaj yeem hais nrog kev ntseeg siab tias tiam tom ntej ntawm tandem roj teeb uas peb tab tom tsim tam sim no yuav ua tau zoo dua.
