Tau qhov twg los: Cov Ntaub Ntawv Muaj Peev Xwm Tshaj Lij
Parasitic absorption nyob rau hauv transparent electrodes yog ib qho ntawm cov mainblocks lub peev xwm ua kom muaj hwj huam hloov hluav taws xob (PCEs) rau perovskite - raws li tandem solar hlwb tshaj 30%. Yuav kom txo cov kev poob qis thiab ua kom pom qhov sib txig sib txuas, qhov dav npaum nrig ntawm cov electrodes yuav tsum raug kho, tshwj xeeb tshaj yog nyob rau ntawm lub hauv ntej ntawm lub cuab yeej.
Txhim kho NIR cov lus teb nyob rau hauv si / tandems duab
Erkan Aydin thiab cov neeg ua hauj lwm los ntawm KAUST Photovoltaics Laboratory tau qhia txog cov khoom zoo heev ntawm Zr - doped indium oxide (IZRO) pob tshab electrodes rau tej daim ntaub ntawv, nrog kev txhim kho nyob ze - lub ploj (NIR) teb piv rau cov pa roj carbon monoxide - doped indium oxide (ITO) electrodes . Optimized IZRO films feature high electron lub neej (txog li ≈ 77 cm2 V-1 s-1), enabling feem ntau infrared pob tshab films nrog ib tug tsis tshua muaj nplooj ntawv kuj ( ≈ 18 Ω -1 rau annealed 100 nm films). Rau cov khoom siv, qhov no txhais mus rau lub cev tsis haum ntawm ≈ 5% rau IZRO hauv hnub ci spectrum (250 - 2500 nm range), muab piv nrog ≈ 10% rau kev lag luam ITO.
Ntxiv thiab, pawg neeg tau qhia 26.2% PCE rau plaub - perovirus peripheral / silicon tandem nrog ib qho 3.5 mA cm-2 luv luv - circuit tam sim no txhim kho nyob rau hauv silicon hauv qab hlwb yog tau los ntawm kev hloov cov lag luam ITO electrodes nrog IZRO.
