Qhov sib txawv tseem ceeb ntawm kev ua haujlwm sab hauv thiab sab nraud quantum yog qhov kev ua haujlwm sab hauv quantum suav nrog siv cov photons uas ci ntsa iab los ntawm sab hauv ntawm lub hnub ci cell, whereas sab nraud quantum efficiency yog xam siv cov photons uas ci ntsa iab los ntawm sab nraud ntawm lub hnub ci. hnub ci cell.
Quantum efficiency lossis QE yog lub tswvyim hauv quantum mechanics. Lo lus no muaj ob daim ntawv thov loj; Nws tuaj yeem siv rau qhov xwm txheej photon hauv kev hloov pauv hluav taws xob piv lub tswv yim (IPCE) ntawm cov khoom siv photosensitive thiab rau TMR nyhuv ntawm qhov sib nqus qhov sib nqus. Thaum xav txog quantum efficiency nyob rau hauv lub hnub ci hlwb, muaj ob hom xws li sab hauv thiab sab nraud quantum efficiency.
Quantum Efficiency hauv Solar Cells yog dab tsi?
Quantum efficiency ntawm lub hnub ci cell txhais cov nqi ntawm tam sim no lub hnub ci cell tuaj yeem tsim raws li irradiation los ntawm photons ntawm ib qho kev wavelength. Peb tuaj yeem ntsuas tus nqi tam sim no uas yog tsim los ntawm lub hnub ci ntawm lub hnub ci thaum nws raug tshav ntuj yog tias lub quantum efficiency ntawm lub xovtooj sib xyaw ua ke dhau tag nrho lub hnub ci electromagnetic spectrum. Yog tias peb tuaj yeem tau txais qhov sib piv ntawm cov nqi tsim hluav taws xob ntawm lub hnub ci ntawm lub hnub ci thiab lub zog ua tau zoo tshaj plaws ntawm lub hnub ci cell, peb tuaj yeem tau txais tag nrho cov nqi hluav taws xob hloov hluav taws xob. Ntxiv mus, peb tuaj yeem tau txais cov txiaj ntsig quantum uas siab dua 100% hauv ntau tiam exciton. Qhov no yog vim lub zog ntawm qhov xwm txheej photon yog ob zaug siab dua lub zog bandgap, uas ua rau tsim ob lossis ntau dua electron-qhov khub ib qhov xwm txheej photon.
Internal Quantum Efficiency yog dab tsi?
Internal quantum efficiency yog qhov sib piv ntawm tus naj npawb ntawm cov cab kuj uas tau sau los ntawm lub hnub ci cell mus rau tus naj npawb ntawm photons muaj lub zog uas tuaj yeem ci rau ntawm lub hnub ci cell los ntawm sab hauv (cov photons no absorbed los ntawm lub hnub ci cell. cell). Kev txiav txim siab ntawm kev ua haujlwm hauv quantum tuaj yeem ua tau raws li hauv qab no:
External Quantum Efficiency yog dab tsi?
External quantum efficiency yog qhov piv ntawm tus naj npawb ntawm cov cab kuj uas tau sau los ntawm lub hnub ci cell mus rau tus naj npawb ntawm photons muaj ib tug muab lub zog tus nqi uas yog shinning los ntawm sab nraud (lub npe hu ua xwm txheej photons). Qhov kev txiav txim siab ntawm sab nraud quantum efficiency yuav ua tau raws li hauv qab no:
Raws li cov lus piav qhia saum toj no qhia, kev ua haujlwm quantum sab nraud yog ib txwm suav nrog siv cov photons uas ci ntsa iab ntawm sab nraum lub hnub ci. Ntxiv mus, sab nraud quantum efficiency nyob ntawm qhov nqus ntawm lub teeb.
Qhov txawv ntawm Internal thiab External Quantum Efficiency yog dab tsi?
Thaum qhov kev ua haujlwm ntawm quantum hauv lub hnub ci tau txiav txim siab, muaj ob hom kev ua haujlwm sab hauv thiab sab nraud quantum. Qhov sib txawv tseem ceeb ntawm sab hauv thiab sab nrauv quantum efficiency yog qhov kev ua haujlwm hauv quantum yog suav nrog siv cov photons uas ci ntsa iab los ntawm sab hauv lub hnub ci cell, whereas sab nraud quantum efficiency yog xam siv cov photons uas yog shinning los ntawm sab nraum lub hnub ci cell. Ntxiv mus, internal quantum efficiency yeej ib txwm muaj tus nqi siab dua lwm quantum efficiency. Tsis tas li ntawd, kev siv hluav taws xob sab hauv quantum tsis nyob ntawm qhov nqus ntawm lub teeb, whereas sab nraud quantum efficiency nyob ntawm qhov nqus ntawm lub teeb.
Cov infographic hauv qab no teev qhov sib txawv ntawm sab hauv thiab sab nraud quantum efficiency nyob rau hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Internal vs External Quantum Efficiency
Thaum xav txog qhov kev ua haujlwm ntawm quantum hauv lub hnub ci, muaj ob hom kev ua haujlwm sab hauv thiab sab nraud quantum. Qhov sib txawv tseem ceeb ntawm sab hauv thiab sab nraud quantum efficiency yog qhov kev ua haujlwm hauv quantum yog suav nrog siv cov photons uas ci ntsa iab los ntawm sab hauv ntawm lub hnub ci cell, whereas sab nraud quantum efficiency yog xam siv cov photons uas shinning los ntawm sab nraum lub hnub ci cell.
