Cov khoom siv thev naus laus zis yog cov khoom siv yooj yim ntawm cov twj siv hluav taws xob thiab cov khoom siv photovoltaic. Lawv qhov tsis muaj zog thiab cov yam ntxwv tsis zoo uas cuam tshuam rau kev ua haujlwm ntawm ntaus ntawv. Nrog rau kev nce hauv kev koom ua ke ntawm cov cuab yeej siv hluav taws xob thiab cov kev hloov pauv ntawm cov khoom siv photovoltaic, cov tseev kom muaj rau semiconductor nyoos cov khoom siv nce zuj zus. Txhawm rau kom tau raws li cov kev xav tau ntawm kev lag luam ntau lawm, cov cuab yeej tshuaj xyuas cov txheej txheem yuav tsum muaj qhov siab dua thiab ntsuas kev nrawm dua, thaum zam kom tsis txhob muaj cov khoom puas tsuaj. Cov nqa khoom muaj lub cev thauj khoom siv tau ntawm cov khoom siv hluav taws xob, thiab lawv cov yam ntxwv thauj khoom txiav txim siab kev ua haujlwm ntawm ntau yam khoom siv optoelectronic, suav nrog cov neeg nqa khoom lub neej, diffusion coefficient, thiab tus nqi sib npaug. Optical carrier radiation yog ib hom ntawm txhua txoj kev kho qhov muag tsis muaj qhov ntsuas kev ntsuas kom tau ntsuas tib lub sijhawm ntawm cov khoom thauj thauj, tab sis hom no tseem muaj qee qhov kev txwv hauv kev ntsuas thiab kev paub ntawm cov tsheb thauj khoom tsis dhau, xws li cov qauv theoretical Siv, ntsuas qhov raug. thiab qhov ceev ntawm cov tsis.
Nrog kev txhawb nqa ntawm National Natural Science Foundation ntawm Tuam Tshoj, lub koom haum ntawm Optoelectronic Technology ntawm Suav Academy ntawm Kev Tshawb Fawb tau coj los ua cov teeb meem saum toj no thiab tsim cov duab hluav taws xob tsis yog duab hluav taws xob nrog cov qauv hluav taws xob semiconductor silicon cov ntaub ntawv ua cov khoom tshawb fawb, thiab ntawm lub hauv paus no, feem tau thov ntau qhov chaw teeb Lub tshuab hluav taws xob tshuab hluav taws xob thiab lub xeev photocarrier hluav taws xob ua duab thev naus laus zis tau lees paub qhov ua tau zoo ntawm cov cuab yeej saum toj no los ntawm kev sim kev suav thiab kev ntsuas ntsuas. Cov chaw zov me nyuam ntau lub teeb hluav taws xob hluav taws xob tuaj yeem tshem tawm cov kev cuam tshuam ntawm lub siab teb ntawm cov ntsuas ntsuas ntawm cov ntsuas ntsuas, thiab txhim kho kev ntsuas qhov tseeb ntawm cov khoom thauj. P-type ib qho siv lead ua kua roj silicon nrog kev tawm tsam 0. 1 - 0. {{6}} Ω? Cm yog Piv txwv, qhov thov kom muaj ntau qhov chaw teeb lub tshuab hluav taws xob hluav taws xob txo cov kev ntsuas tsis txaus ntseeg ntawm cov neeg nqa khoom lub neej, kev sib txawv ntawm cov pa thiab qhov sib cuam tshuam ntawm qhov chaw ntawm traditional 15. 9%, ± {{{{16 }}}}} 9. 1% thiab> ± 50% rau ± 1 0.. {{1 4}}%, ± 8. 6% thiab ± 35. { {18}}%. Ib qho ntxiv, lub xeev-photocarrier hluav taws xob thaij duab hluav taws xob ua kom yooj yim cov qauv theoretical thiab cov cuab yeej ntsuas, ntsuas qhov ntsuas tau zoo heev, thiab muaj daim ntawv thov kev lag luam ntau dua.
