Lub hauv paus ntsiab lus ntawm kev hloov lub hnub ci zog rau hauv ntau lub zog yog: lub teeb lub zog excites electrons los tsim hluav taws xob hluav taws xob;lub zog ntawm electrons tsim hluav taws xob tam sim no, yog li hloov lub teeb lub zog rau hauv hluav taws xob hluav taws xob.
Cov txheej txheem ntawm kev hloov lub hnub ci zog rau hauv lub zog hluav taws xob yog hu ua photovoltaic zog tsim.Lub hauv paus ntsiab lus ntawm kev tsim hluav taws xob photovoltaic yog siv cov photons nyob rau hauv tshav ntuj los txhawb cov electrons nyob rau hauv photovoltaic hlwb los tsim tam sim no.Lub cell photovoltaic yog ib qho khoom siv semiconductor feem ntau muaj ntau yam silicon wafers.
Lub silicon wafer muaj ob yam khoom, phosphorus-doped silicon thiab boron-doped silicon, uas muaj cov qauv hluav taws xob sib txawv.Thaum tshav ntuj hits silicon wafer, photons ntaus electrons nyob rau hauv silicon wafer, txaus siab rau lawv los ntawm lawv atoms thiab tsim electron-qhov khub nyob rau hauv lub wafer.Silicon doped nrog phosphorus yog n-hom semiconductor, thiab silicon doped nrog boron yog p-hom semiconductor.Thaum ob qho kev sib txuas, ib qho hluav taws xob tau tsim, thiab hluav taws xob ua rau cov hluav taws xob txav mus thiab tsim ib qho tam sim no.
