AM, Nanjing University: Ib qho yooj yim-voltage fais fab tuag ntaus ntawv raws li asymmetric photovoltaic cascade
Dec 26, 2022
Kev sib hloov ntawm lub teeb thiab hluav taws xob yog nyob rau hauv plawv ntawm optoelectronic thiab photonic daim ntaub ntawv. Lub maximization ntawm photoelectric hloov dua siab tshiab yog lub hom phiaj mus sij hawm ntev thiab tuaj yeem ua tiav los ntawm kev tsim cov khoom siv nrog cov qauv tshwj xeeb. Nyob rau hauv lub moj khaum no, nws yog ib qho tseem ceeb heev uas yuav tau sau optical hluav taws xob nyob rau hauv ib cheeb tsam tshwj xeeb thiab hloov mus rau hauv ib tug functional dielectric nrog ib tug siab hluav taws xob muaj peev xwm tsav lub teb rau ib tug ntshiab hluav taws xob teb.
Li Zhang et al. ntawm Nanjing University tau tsim cov txheej txheem nanofabrication featuring ob chav self-alignment thiab siv nws rau kev tsim kho ntawm zebra-zoo li asymmetric heterojunction arrays.
Cov kws sau ntawv tau npaj ib qho tshiab asymmetric, ncua sij hawm thiab taw qhia nanocomposite muaj li ntawm kub thiab txhuas strips. Qhov no bimetallic nanostructure tso cai rau lub koom haum ntawm pn heterojunctions nyob rau hauv ib tug tswj nyob rau hauv cov kev taw qhia ntawm kev sib raug zoo. Illuminated 5 x 4 mm2 arrays ntawm cov duab plaub me me tuaj yeem tsim cov hluav taws xob siab tshaj 100 V ntawm cov khoom hloov pauv tau yooj yim. Lub peev xwm tsim tau ib chav tsev ntev txog li 350 V-cm-1. Cov kws sau ntawv ua qauv qhia thawj zaug tias cov high voltages tuaj yeem tsim los ntawm tus kheej-powered compact system-on-a-chip.
Cov kws sau ntawv qhov kev tshawb pom pab txhawb kev hloov pauv ntawm lub teeb thiab hluav taws xob, mus txog qhov chaw uas qhov kev ua tau zoo ntawm piezoelectric thiab electro-optical cov ntaub ntawv nyob rau hauv nws tus kheej-powered ntse twj yuav tswj tau los ntawm muab ib tug txaus loj electrostatic teb.
