PV Power Generation tau ua qhov kev tshaj lij thev naus laus zis tshiab
Ib pab pawg ntawm King Abdullah University of Science thiab Technology (KAUST) hauv Saudi Arabia nyuam qhuav teeb tsa cov ntaub ntawv ua haujlwm tshiab rau cov hnub ci txuas nrog. Siv lub npe hu ua tandem solar cells, uas muab ob yam khoom sib txawv, pab pawg tuaj yeem ua tiav qib kev ua haujlwm zoo.
Lub tandem hnub ci hlwb tau tsim los ntawm stacking ob nyias zaj duab xis solar cells nyob rau sab saum toj ntawm ib leeg. Sab saum toj ntawm tes yog ua los ntawm cov khoom siv hlau-halide perovskite, thaum lub cell hauv qab yog ua los ntawm cov khoom siv silicon. Ob lub hlwb tau txuas nrog lub pob tshab conductive nplaum. Qhov no tso cai rau cov hlwb ua haujlwm ua ke kom zoo dua los ntes lub hnub thiab tsim hluav taws xob.
Pab pawg KAUST tau ua tiav qib kev ua haujlwm ntawm 33.2%, tshaj li cov ntaub ntawv dhau los ntawm 32.5% rau hom tshwj xeeb ntawm lub hnub ci. Qhov kev txhim kho no ua rau txoj hauv kev kom muaj txiaj ntsig zoo dua thiab muaj txiaj ntsig zoo hnub ci tsim hluav taws xob.
Dr. Stefaan De Wolf, Associate Professor of Photovoltaics ntawm KAUST tau hais tias "Qhov kev ua tau zoo ntawm cov ntaub ntawv no qhia txog lub peev xwm ntawm tandem solar cells, tshwj xeeb tshaj yog rau cov hnub ci kev ua haujlwm siab," said Dr.
Tandem hnub ci hlwb tau txais kev muaj koob meej nyob rau hauv xyoo tas los no vim lawv muaj peev xwm ntes tau ntau lub hnub ci spectrum. Qhov no ua rau muaj kev ua tau zoo dua thiab cov nqi qis dua ib watt ntawm hluav taws xob tsim. Nrog rau qhov kev hloov tshiab no, pab pawg KAUST tau pab ua kom lub hnub ci zog txawm tias muaj kev sib tw nrog cov khoom siv hluav taws xob ib txwm muaj.
