Lub ntsiab yog vim li cas rau tam sim no tsis tshua muaj conversion efficiency ntawm lub hnub ci vaj huam sib luag yog qhov poob ntawm "tsawg-zog photon zog" thiab "siab-zog photon zog", ob qho tib si txwv qhov theoretical txwv efficiency ntawm solar panels txog li 40%. Cov hauv qab no luv luv piav qhia txog kev txhim kho rau txhua qhov kev poob.
1. Txo qis -zog photon zog poob
Siv cov khoom siv qis qis optoelectronic semiconductor, piv txwv li, qhov sib txawv ntawm cov khoom siv 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 siab photon zog poob
Siv cov khoom siv high-band gap optoelectronic semiconductor. Txhawm rau suav cov thawj ob lub ntsiab lus, kev sib xyaw ua ke ntawm ntau yam -bandgap semiconductor cov ntaub ntawv tuaj yeem txhim kho qhov kev siv ntawm photons nrog lub zog sib txawv.
3. Txo kev nqus tau zoo thiab kev xav tsis zoo: (1) sim siv cov khoom siv hluav taws xob nrog lub teeb pom kev siab coefficients; (2) txo qhov chaw 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 ntaub ntawv, Reflective txheej cov ntaub ntawv los txo qhov kev xav tsis zoo los ntawm qhov kev xav ntawm qhov chaw.
4. Txo qhov qhib Circuit Court voltage poob. Kho qhov concentration ntawm impurity impurities thiab Fermi qib ntawm raw khoom.
5. Txo cov khoom poob: (1) siv cov txheej txheej passivation los txo cov dangling bonds ntawm lub hnub ci vaj huam sib luag nto los yog sab nraum qab electrode; (2) siv siab-purity (tsawg- impurity) cov ntaub ntawv hnub ci vaj huam sib luag thiab cov txheej txheem tsim khoom zoo dua los txo cov khoom siv Internal ntim recombination; (3) Siv cov conductors zoo li electrodes thiab txais yuav zoo dua electrode qauv tsim kom txo tau series kuj.
