Iimodyuli zePV ezinobomi obude zinokunciphisa iMbango yezinto, itsho i-NREL

I-US National Renewable Energy Laboratory (NREL) ithi kwingxelo entsha ukuba ukongezwa kwemodyuli ye-PV kufuneka ibekwe phambili ngaphezu kokuhlaziywa kwe-loop evaliweyo ukunciphisa imfuno yezinto ezintsha.

NRELuye wavavanya urhwebo phakathi kokwandiswa kwexesha lobomi bemodyuli yePV okanye ukunyusela iluphu evaliweyoukurisayikilishwakwiiphaneli zelanga ezinobomi obufutshane.Ibonise iziphumo zayo "ISetyhula yezoQoqosho eziPhambili kwi-Photovoltaics kwi-Energy Transition,” esandul’ ukupapashwa kwiPLOS One.

Ukusebenzisa iUnited States njengesifundo somzekelo, iqela labaphandi bahlalutya iimeko ze-336 zisebenzisa i-PV Circular Economy Tool (PV ICE) yangaphakathi.Baqwalasela kuphela iimodyuli ezisekelwe kwi-silicon esekelwe kwi-monocrystalline.

Abaphandi bavavanya impembelelo kwimfuno yezinto ezintsha kunye nobomi bemodyuli eyahlukeneyo, ukusuka kwi-15 ukuya kwi-50 iminyaka.Baphinde bajonga kwi-closed-loop recycling, kwaye bacingela ukuba i-United States iya kuba ne-1.75 TW ye-cumulative PV efakwe umthamo ngo-2050.

Iziphumo zibonisa ukuba iimodyuli ezineminyaka engama-50 yokuphila zinganciphisa imfuno yezinto ezintsha nge-3% ngokusetyenziswa okuphantsi, xa kuthelekiswa ne-35-year baseline scenario.Ngakolunye uhlangothi, iimodyuli ezine-15-year-lifetimes ziza kufuna i-1.2 TW eyongezelelweyo yeemodyuli zokutshintsha ukugcina i-1.75 TW ye-PV umthamo ngo-2050. Oko kuya kwandisa imfuno yezinto ezintsha kunye nenkcitho ngaphandle kokuba ngaphezulu kwe-95% yobunzima bemodyuli yayivaliwe-loop. zisetyenziswe ngokutsha, batsho abaphandi

"Oku kufuna i-100% yokuqokelela kunye nemveliso ephezulu, ixabiso eliphezulu leenkqubo zokuphinda zisetyenziswe, ezibonisa iteknoloji kunye nomngeni wokulawula ngenxa yokuba akukho teknoloji ye-PV iphumelele eli nqanaba lokuphinda lisetyenziswe kuzo zonke izinto zecandelo," batsho.

Bongeze ukuba ngamatyathanga obonelelo lwe-PV oluzinzileyo, kukho utyekelo lokuya ngokuthe ngqo ekusetyenzisweni kwakhona njengesisombululo, kodwa kukho ezinye iinketho ezininzi zeesetyhula zokuzama kuqala, njengokwandiswa kwexesha lokuphila.Baqukumbele ngelithi "ukulungisa imfuno yezinto ezintsha kunokufezekiswa ngeendlela ezingezizo ukurisayikilishwa kwakhona, kubandakanywa isivuno esiphezulu, ukusebenza kakuhle, iinkqubo ezithembekileyo (ngaloo ndlela kuncitshiswa ukutshintshwa kunye neemfuno zokusasazwa zizonke,) ukwenziwa ngokutsha kwamacandelo, kunye nokukhangela izinto ezijikelezayo."
