US National Renewable Energy Laboratory (NREL) hais tias nyob rau hauv tsab ntawv tshaj tawm tshiab hais tias PV module lub neej txuas ntxiv yuav tsum tau ua ntej tshaj qhov kev rov ua dua tshiab kaw los txo qhov kev thov rau cov ntaub ntawv tshiab.

NRELtau soj ntsuam kev lag luam tawm ntawm kev txuas ntxiv PV module lub neej los yog ramping li kaw-vojrov ua duarau cov hnub ci vaj huam sib luag nrog lub neej luv luv.Nws nthuav tawm nws cov kev tshawb pom hauv "Circular Economy Priorities for Photovoltaics nyob rau hauv Kev Hloov Hluav Taws Xob,” uas nyuam qhuav luam tawm hauv PLOS Ib.
Siv Tebchaws Meskas los ua qhov kev tshawb fawb, ib pab pawg kws tshawb fawb tau tshuaj xyuas 336 qhov xwm txheej uas siv cov cuab yeej hauv tsev PV Circular Economy (PV ICE).Lawv tsuas yog suav tias yog monocrystalline silicon-based modules.
Cov kws tshawb fawb tau soj ntsuam qhov cuam tshuam rau cov khoom siv tshiab nrog cov qauv sib txawv ntawm lub neej, los ntawm 15 txog 50 xyoo.Lawv kuj tau saib ntawm kev kaw-loop rov ua dua tshiab, thiab xav tias Tebchaws Meskas yuav muaj 1.75 TW ntawm kev tsim cov PV tsim los ntawm 2050.
Cov txiaj ntsig tau pom tias cov qauv nrog 50-xyoo lub neej tuaj yeem txo cov khoom siv tshiab los ntawm 3% los ntawm kev xa mus qis dua, piv nrog 35-xyoo qhov xwm txheej.Ntawm qhov tod tes, modules nrog 15-xyoo lub neej yuav xav tau ib qho ntxiv 1.2 TW ntawm cov khoom hloov pauv kom tswj tau 1.75 TW ntawm PV peev los ntawm 2050. Qhov ntawd yuav nce cov khoom siv tshiab thiab cov khoom pov tseg tshwj tsis yog tshaj 95% ntawm cov module loj tau kaw-loop. recycled, hais tias cov kws tshawb fawb
"Qhov no yuav tsum tau 100% kev sau thiab cov txheej txheem rov ua dua tshiab, muaj txiaj ntsig zoo, uas nthuav tawm kev sib tw thev naus laus zis thiab kev tswj hwm vim tias tsis muaj PV thev naus laus zis tau ua tiav qib ntawm kev rov ua dua tshiab rau txhua yam khoom siv," lawv hais.
Lawv tau hais ntxiv tias nrog cov saw hlau PV muaj kev ruaj ntseg, muaj kev nyiam mus ncaj nraim rau kev rov ua dua tshiab raws li kev daws teeb meem, tab sis muaj ntau ntau lwm yam kev xaiv los sim ua ntej, xws li kev txuas mus rau lub neej.Lawv xaus lus tias "kev tawm tsam cov khoom siv tshiab tuaj yeem ua tiav hauv txoj hauv kev uas tsis yog kev rov ua dua tshiab, suav nrog cov txiaj ntsig siab, ua haujlwm siab, txhim khu kev qha systems (yog li txo qis kev hloov pauv thiab tag nrho cov kev xav tau xa mus,) rov tsim khoom ntawm cov khoom, thiab cov khoom siv ncig."
