Hnub ci Module Efficiency tuaj yeem tshaj 35% Los ntawm 2050

Pab pawg tshawb fawb thoob ntiaj teb los ntawm cov tuam txhab hnub ci PV thiab cov tuam txhab tau txheeb xyuas qhov tseem ceeb tshaj plaws R&D tiam sis rau qhov nws hu ua lub sijhawm tshiab ntawm ntau -terawatt photovoltaics.

Cov tswv cuab ntawm pab pawg yog tag nrho ib feem ntawm 4th Terawatt Rhiav, ib qho ntawm cov qib siab - theem thoob ntiaj teb PV kev cob qhia coj los ntawm lub teb chaws Yelemees's Fraunhofer-Institut für Solare Energiesysteme ISE (Fraunhofer ISE), US Department of Energy's National Laboratory of the Rockies, thiab Nyiv's Science Technology.

Hauv lawv cov ntawv tshiab, "Keeb kwm thiab yav tom ntej kev kawm rau lub sijhawm tshiab ntawm ntau-terawatt photovoltaics," tsis ntev los no tau tshaj tawm hauv Nature Energy, pab pawg kwv yees txuas ntxiv txhim kho hauv PV nqi, kev ua tau zoo, thiab kev ntseeg siab, nrog rau kev siv peev txheej, emissions, thiab rov ua dua tshiab hauv kev tsim thiab tsim khoom yav tom ntej.

Andreas Bett, tus thawj coj ntawm Fraunhofer ISE, tau hais hauv kev xam phaj nrog pv magazine hais tias "Lub hnub ci kev ua haujlwm yuav ntau dua 35% los ntawm cov qauv tsim los ntawm 2050. Nws hais ntxiv tias kev ua haujlwm ntawm tes tuaj yeem tshaj 36%, nrog rau cov xov tooj qis dua - mus rau - qauv poob dua li niaj hnub no. "Thaum kawg ntawm thawj ib nrab ntawm lub xyoo pua no, cov nqi hnub ci module yuav poob los ntawm ib qho ntawm ob."

Bett tau hais tias ob qho tib si kev ua tau zoo dua thiab cov nqi qis dua yuav yog qhov tseem ceeb rau kev hloov pauv ntawm lub zog, tab sis nws pom tias qhov ua tau zoo yog qhov tseem ceeb dua. "Kev ua haujlwm siab dua txhais tau tias cov khoom siv tsawg dua thiab cov av tsawg dua yog xav tau rau kev teeb tsa PV, uas txhim kho kev ruaj khov thiab txo cov nqi tag nrho," nws hais ntxiv tias hnub ci module lub neej yuav "tseem ceeb" txuas ntxiv mus txog 40 xyoo.

Cov kws tshawb fawb tau hais tias kev lag luam PV tau dhau mus dhau qhov kev kwv yees ua ntej rau cov nqi module, kev ua haujlwm, thiab kev sib koom ua ke. Kev tsim kho tshiab hauv tandem architectures thiab kev tsim khoom yuav tsum muaj rau PV thev naus laus zis xws li crystalline silicon (c-Si), cadmium telluride (CdTe), thiab tooj liab, indium, gallium thiab diselenide (CIGS) tuaj yeem thiab yuav tsum ua kom cov neeg tshiab nkag mus rau hauv kev ua lag luam, tsim kom muaj ntau lub xov tooj ntawm tes thiab cov khoom siv thoob ntiaj teb.

Lawv kuj tau piav qhia tias qhov tshiab tandem PV thev naus laus zis yuav tsum tau txhais kom meej qhov kev ua tau zoo, ua kom pom tseeb lub zog tso zis, tshawb xyuas qhov ua tsis tiav thaum ntxov, thiab tswj hwm qhov tsis paub txog kev pheej hmoo degradation, nrog rau qhov kawg yog ib qho kev sib tw rau Si modules tam sim no thiab tseem ceeb heev rau kev tshwm sim perovskite- raws li technologies.

Txoj kev tshawb fawb no hais tias lub ntiaj teb hnub ci kev tsim muaj peev xwm tuaj yeem ncav cuag li 3 TW los ntawm 2050 thiab hais txog tias kev ruaj khov - kev kawm tau raug txo qis thiab yuav yog qhov tseem ceeb ntxiv rau kev lag luam PV kom ruaj ntseg cov peev txheej uas xav tau rau kev loj hlob yav tom ntej.

"Cov ncauj lus rau yav tom ntej PV lub rooj sib tham hauv zej zog, xws li 4th Terawatt Rhiav uas tau qhia txog qhov Kev Pom Zoo no, tuaj yeem hloov mus rau kev hais lus thiab xaus -cov neeg siv xav tau," cov kws tshawb fawb xaus lus. "Kev nqis peev, kev tsim khoom, thiab kev saws me nyuam niaj hnub no yuav them cov nyiaj tau los hloov pauv thoob ntiaj teb tag kis ntawm kev loj hlob ntawm kev lag luam, kev tsim khoom, kev tsim haujlwm, thiab txo cov pa phem thiab kev txom nyem."

Cov pab pawg tshawb fawb suav nrog cov kws tshawb fawb los ntawm lub teb chaws Yelemees Forschungszentrum Jülich GmbH, Japanese hnub ci iav tsim AGC Inc, Finland's LUT University, Tuam Tshoj lub koom haum Yangtze rau Hnub Ci Technology, UK perovskite hnub ci kws tshwj xeeb Oxford Photovoltaics Ltd, Suav module tsim Trina Solar, Saudi Arabia's Abstract Solar Center, New University of South Africa thiab King Wales (UNSW) hauv Australia, Asmeskas nyias- cov chaw tsim khoom ua yeeb yaj kiab First Solar, Nyiv National Institute of Advanced Industrial Science thiab Technology (NEDO), thiab Singapore-raws li PV chaw tsim khoom Maxeon, thiab lwm yam.
