Kev ua haujlwm ruaj khov ntawm Perovskite roj teeb nce mus txog 26.7%!

Thaum Lub Xya Hli 3rd, cov ntawv pov thawj thoob ntiaj teb lub hnub ci cell ntiaj teb cov ntaub ntawv teev npe "Solar cell efficiency tables" (Version 64) tau tshaj tawm lub ntiaj teb cov ntaub ntawv rau kev ua tau zoo ntawm perovskite roj teeb coj los ntawm Xu Jixian pab neeg ntawm University of Science thiab Technology ntawm Tuam Tshoj, nrog rau kev ua haujlwm ntawm cov roj teeb perovskite. certified ruaj khov-lub xeev efficiency kev ua tau zoo ntawm 26.7%.

Qhov no yog zaum thib peb uas pab neeg tau hloov kho cov ntawv teev npe hauv ntiaj teb txuas ntxiv sawv cev ntawm University of Science thiab Technology ntawm Tuam Tshoj txij li xyoo 2022 (Version 60) thiab 2023 (Version 63). Hauv xyoo 2023, pab pawg tau ua tiav ob qho kev sib tw hauv kev ua haujlwm ntawm cov roj teeb perovskite, tshaj 26% thiab rhuav tshem lub ntiaj teb cov ntaub ntawv rau cov khoom siv ib txwm siv, nrog rau kev ua haujlwm tau ntawv pov thawj ntawm 26.1% rau cov khoom siv trans. Qhov kev ua tiav no yog lwm qhov kev ua tiav hauv kev tshawb fawb txuas ntxiv thiab nyuaj ntawm lub hauv paus no, uas muaj kev txhawb nqa zoo rau kev tsim kho cov roj teeb uas muaj teeb meem.

Hnub Ci Cell Efficiency Tables raug tshuaj xyuas thiab luam tawm los ntawm Australian Advanced Photovoltaic Center hauv kev koom tes nrog cov kws tshawb fawb los ntawm ntau lub tebchaws suav nrog Tebchaws Meskas, Nyiv, Ltalis, thiab Australia. Nws muaj keeb kwm ze li ntawm 30 xyoo thiab tau lees paub los ntawm thoob ntiaj teb kev kawm photovoltaic thiab kev lag luam rau nws cov hom phiaj thiab kev hwm. Nws sawv cev rau qhov kev txhim kho thev naus laus zis tshiab tshaj plaws hauv ntau lub sub sectors ntawm photovoltaics thiab muaj kev taw qhia tseem ceeb. Qhov kev suav nrog no sawv cev rau kev ua tiav thiab kev muaj peev xwm ntawm Tuam Tshoj University of Science thiab Technology nyob rau hauv pem hauv ntej ntawm photovoltaic kev tshawb fawb thiab kev loj hlob.

Txoj kev tshawb no yog qhov kev ua tiav tshiab kawg ntawm Xu Jixian pab pawg hauv thaj chaw tshiab perovskite ib qho kev sib tshuam thiab lwm tiam crystalline silicon perovskite stacked roj teeb, uas muaj kev txhawb nqa kev lag luam. Txoj haujlwm no yog txhawb nqa los ntawm National Natural Science Foundation ntawm Tuam Tshoj, Ministry of Science thiab Technology ntawm Tuam Tshoj, Anhui Provincial Industrial Innovation Project, thiab Carbon Neutrality Research Institute ntawm University of Science thiab Technology ntawm Tuam Tshoj.
