Ntawm 48th IEEE Photovoltaic Cov Kws Tshaj Lij Sib Tham xyoo no, cov kws tshawb fawb los ntawm Fraunhofer Institute of Solar Energy System ISE, Lub Tebchaws Yelemees, tau qhia pom qhov tshwm sim ntawm gallium arsenide (GaAs) -based III-V semiconductor photovoltaic cells mus rau laser ntawm 858 nm wavelengthand thiab paub qhov tseeb ntawm 68.9% kev hloov pauv tau zoo. Nws tau hu ua dab neeg vim tias kev hloov pauv kev ua haujlwm ntawm 68.9% yog nyob deb tshaj qhov muaj txiaj ntsig tshaj plaws rau kev hloov lub teeb rau hauv hluav taws xob! Hauv kev ua qauv qhia, pab pawg tshawb fawb tau siv lub hnub ci ci heev ntawm tes (ua los ntawm gallium arsenide) thiab nruab nws nrog qhov ua tau zoo, tsom iav tsom iav tom qab.
Hauv cov cell photovoltaic, lub teeb tau nqus rau hauv cov qauv ntawm tes. Lub teeb nqus tau tso tawm qhov zoo thiab qhov tsis zoo, uas tom qab ntawd ua rau lub roj teeb pem hauv ntej thiab sab nraub qaum, yog li tsim hluav taws xob. Thaum lub zog ntawm qhov teeb meem teeb pom kev siab me ntsis siab dua li qhov hu ua band sib txawv lub zog uas muaj nyob hauv cov khoom siv hluav taws xob, cov duab photovoltaic yuav muaj zog tshwj xeeb. Yog li ntawd, thaum lub teeb pom kev zoo monochromatic tau sib phim nrog cov khoom siv hluav taws xob tsim nyog tsim nyog, nws yog kev xav tau los ua kom muaj kev hloov pauv siab heev.
Daim ntawv no ntawm kev xa hluav taws xob nrog kev koom nrog thev naus laus zis laser tseem hu ua lub teeb thev naus laus zis thev naus laus zis. Nws yog qhov tshwj xeeb tshaj yog rau cov ntawv thov uas xav tau cov khoom siv hluav taws xob sib cais, tiv thaiv hluav taws xob lossis tiv thaiv kev tawg, hluav taws xob sib txuas, lossis ua tiav lub zog xa hluav taws xob tsis siv.
Piv nrog rau ib txwm tooj liab cable fais fab kis tau tus mob, xws li photokinetic zog system muaj ob qhov pom tseeb zoo. Dr. Henning Helmers, tus thawj coj ntawm Fraunhofer ISE tshawb fawb pab pawg, piav qhia:" Ua ntej, cov photons raug ntes hauv lub roj teeb, ze rau ntawm qhov sib txawv band. Kev nqus ntawm photon lub zog tuaj yeem ua kom ntau ntxiv, thiab tib lub sijhawm, cua sov thiab kis tau poob tuaj yeem txo qis. Qhov thib ob, cov duab hluav taws xob tau tsim sab hauv tau raug ntes thiab ua haujlwm zoo los ntawm kev siv hluav taws xob rov ua dua tshiab, uas ua rau lub neej muaj txiaj ntsig zoo ntxiv thiab ntxiv Voltage ntxiv."
Xibfwb Andreas Bett, Tus Thawj Coj ntawm Lub Tsev Haujlwm, hais tias zoo siab:" Cov kev tshawb fawb no qhia tau tias thev naus laus zis thev naus laus zis muaj peev xwm rau kev siv ua lag luam uas tsis yog hnub ci zog."
Qhov tseeb, ua tsaug rau riam phom khawv koob ntawm laser, daim ntawv thov ntawm hom kev xa xov hluav taws xob no tau dhau los ua ntau yam, suav nrog kev saib xyuas cov cua tshuab cua, saib xyuas cov kab hluav taws xob siab, ntsuas roj hauv lub dav hlau roj tso tsheb hlau luam lossis cog cog sab nraum lub cev. Cov khoom siv kho qhov muag, kev saib xyuas lub network tsis zoo lossis lub zog siv hluav taws xob rau IoT daim ntawv thov, thiab lwm yam.
