Photovoltaic cells hloov lub hnub ci rau hauv hluav taws xob

Lub photovoltaic (PV) cell, feem ntau hu ua lub hnub ci cell, yog ib qho khoom siv tsis siv neeg uas hloov lub hnub ci ncaj qha mus rau hluav taws xob. Qee lub hlwb PV tuaj yeem hloov lub teeb ci rau hauv hluav taws xob.

Photons nqa lub hnub ci zog

Lub hnub ci yog tsim los ntawm photons, los yog cov khoom ntawm lub hnub ci zog. Cov photons muaj ntau lub zog sib txawv uas sib haum rau qhov sib txawv wavelengths ntawm lub hnub ci spectrum.

PV cell yog ua los ntawm cov khoom siv semiconductor. Thaum photons tawm tsam PV cell, lawv tuaj yeem cuam tshuam tawm ntawm lub xov tooj ntawm tes, hla ntawm lub xovtooj, lossis raug nqus los ntawm cov khoom siv semiconductor. Tsuas yog cov photons absorbed muab lub zog los tsim hluav taws xob. Thaum cov khoom siv semiconductor absorbs lub hnub ci txaus (lub hnub ci zog), electrons raug tshem tawm ntawm cov khoom siv atoms. Kev kho tshwj xeeb ntawm cov khoom nto thaum lub sij hawm tsim khoom ua rau pem hauv ntej ntawm lub xov tooj ntawm tes tau txais ntau dua rau cov khoom tawg, lossis dawb, electrons kom cov electrons ib txwm txav mus rau saum npoo ntawm tes.

Kev khiav ntawm hluav taws xob

Kev txav ntawm cov hluav taws xob, txhua tus nqa cov nqi tsis zoo, mus rau pem hauv ntej ntawm lub xov tooj ntawm tes tsim qhov tsis sib xws ntawm cov hluav taws xob hluav taws xob ntawm lub xov tooj ntawm sab xub ntiag thiab sab nraub qaum. Qhov kev tsis txaus ntseeg no, dhau los, tsim kom muaj qhov muaj peev xwm zoo li qhov tsis zoo thiab qhov zoo ntawm lub roj teeb. Hluav taws xob conductors ntawm lub cell nqus cov electrons. Thaum cov conductors txuas rau hauv ib qho hluav taws xob Circuit Court rau ib qho khoom siv sab nraud, xws li roj teeb, hluav taws xob ntws hauv Circuit Court.
