Txoj hauv kev los txo cov efficiency poob ntawm hnub ci vaj huam sib luag
Oct 26, 2021
Lub ntsiab yog vim li cas rau qhov tsawg conversion efficiency ntawm lub hnub ci vaj huam sib luag tam sim no yog qhov poob ntawm" low-zog photon zog" thiab" siab-zog photon zog", ob qho tib si txwv qhov kev txwv theoretical txwv efficiency ntawm hnub ci vaj huam sib luag mus txog 40%. Cov hauv qab no luv luv piav qhia yuav ua li cas txhim kho txhua qhov kev poob.
1. Txo lub zog poob ntawm cov hluav taws xob tsawg photons
Siv cov khoom siv qis-band optoelectronic semiconductor, piv txwv li, qhov sib txawv ntawm qhov sib txawv ntawm cov crystalline silicon yog 1.1 eV, yog li nws tsuas tuaj yeem nqus cov photons nrog lub wavelength luv dua 1100 nm.
2. Txo lub zog poob ntawm high-zog photons
Siv high band gap optoelectronic semiconductor cov ntaub ntawv. Raws li thawj ob lub ntsiab lus, kev siv ntawm kev sib xyaw ua ke ntawm cov khoom siv sib txawv ntawm cov khoom siv hluav taws xob sib txawv tuaj yeem ua kom muaj txiaj ntsig zoo ntawm kev siv cov photons nrog lub zog sib txawv.
3. Txo qhov nqus tau zoo thiab qhov kev xav tsis zoo: (1) Siv cov khoom siv semiconductor nrog lub teeb pom kev siab coefficient kom ntau li ntau tau; (2) Txo cov cheeb tsam ntawm cov hlau electrodes thiab siv cov pob tshab conductive electrodes los hloov qee cov hlau electrodes; (3) Ua kom lub ntsej muag roughness ntawm cov khoom siv thiab siv cov khoom siv tiv thaiv corrosion Reflective txheej los txo qhov kev xav tsis zoo los ntawm kev cuam tshuam saum npoo.
4. Txo qhov qhib Circuit Court voltage poob. Kho qhov concentration ntawm doped impurities thiab Fermi theem txoj hauj lwm ntawm raw khoom.
5. Txo cov khoom poob: (1) Siv cov txheej txheej passivation ntawm tus ciam teb ntawm lub hnub ci vaj huam sib luag saum npoo los yog rov qab electrode kom txo cov dangling bonds; (2) Siv high-purity (tsis muaj impurity) cov ntaub ntawv hnub ci vaj huam sib luag thiab cov txheej txheem kev npaj zoo dua los txo cov khoom siv hauv lub cev rov ua dua; (3) Siv cov conductors zoo li electrodes, thiab txais yuav zoo dua electrode qauv tsim kom txo tau series kuj.
