Paub txog lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub hnub ci, cia' s sib tham txog dab tsi cuam tshuam rau photoelectric conversion efficiency ntawm lub hnub ci hlwb. Peb paub tias cov txheej txheem ua haujlwm ntawm lub hnub ci tuaj yeem kwv yees muaj plaub ntu, uas yog: 1. Cov photons (lub zog ntau dua li qhov txwv tsis pub band dav ntawm semiconductor) irradiated rau saum npoo ntawm lub roj teeb yog absorbed los tsim electron-qhov khub; 2. Electron-hole khub yog Cov kab hluav taws xob built-in yog sib cais los tsim hluav taws xob muaj peev xwm ntawm ob qho kawg ntawm PN hlws ris; 3. Txuas PN kev sib tshuam nrog cov xov hlau los ua ib qho tam sim no; 4. Txuas lub thauj khoom ntawm ob qho kawg ntawm lub hnub ci cell kom paub txog kev hloov ntawm lub teeb lub zog mus rau lub zog hluav taws xob. Yog li ntawd, nyob rau hauv plaub txheej txheem no, muaj cov yam tseem ceeb uas cuam tshuam rau lub photoelectric hloov dua siab tshiab efficiency, uas yog, optical poob nyob rau hauv cov txheej txheem nqus, recombination ntawm lub teeb-excited electron-qhov khub nyob rau hauv lub photovoltaic conversion txheej txheem, thiab poob nyob rau hauv tam sim no. cov txheej txheem tso zis. Hauv qab no peb qhia lawv ib tug los ntawm ib tug.
Optical poob
Raws li lub teeb irradiates lub roj teeb vaj huam sib luag, kev xav, refraction thiab lwm yam tshwm sim tshwm sim nyob rau hauv pem hauv ntej thiab nraub qaum sab, los yog photons nrog lub zog tsawg dua los yog ntau tshaj qhov txwv band dav ntawm lub semiconductor tsis absorbed, thiab cov electrodes, kab sib chaws, thiab lwm yam. . raug thaiv, yog li txo cov roj teeb luv luv tam sim no. Qhov kev poob no tsuas txwv qhov kev hloov pauv ntawm cov roj teeb txheem mus txog 44%. Daim duab schematic ntawm optical poob yog qhia hauv daim duab (2).
2. Lub teeb-excited recombination ntawm electron-qhov khub
Qhov sib xyaw ua ke tsis cuam tshuam tsis yog tsuas yog cov khoom siv tam sim no (luv luv Circuit Court tam sim no) tab sis kuj tseem cuam tshuam rau pem hauv ntej kev txhaj tshuaj tam sim no (qhib Circuit Court voltage).
Recombination feem ntau yog cais raws li thaj chaw uas nws tshwm sim hauv lub roj teeb. Piv txwv li, lub recombination ntawm qhov chaw hu ua nto recombination; recombination nyob rau hauv lub roj teeb yog hu ua bulk recombination, uas yog lub ntsiab recombination ntawm lub roj teeb; lub recombination nyob rau hauv lub depletion cheeb tsam yog hu ua depletion zone recombination.
