Lub zog tsim lub hauv paus ntsiab lus ntawm lub hnub ci vaj huam sib luag yog feem ntau raws li cov nyhuv photoelectric, ib qho tshwm sim uas ncaj qha hloov lub teeb lub zog rau hauv hluav taws xob hluav taws xob.
Thaum tshav ntuj ci rau ntawm lub hnub ci vaj huam sib luag, cov khoom siv semiconductor hauv lub vaj huam sib luag absorbs photon zog. Lub zog photon no ua rau cov khoom siv hluav taws xob hauv lub semiconductor, ua rau lawv dhia los ntawm valence band mus rau lub conduction band, ua electron -qhov khub. Hauv cov khoom siv hluav taws xob, cov khoom siv hluav taws xob thiab cov qhov txav mus rau qhov sib txawv: cov hluav taws xob txav mus rau N- hom cheeb tsam, thaum lub qhov txav mus rau P- hom cheeb tsam, yog li tsim qhov sib txawv, lossis qhov hluav taws xob, hla lub hnub ci vaj huam sib luag. Thaum ib qho hluav taws xob sab nraud txuas nrog, cov hluav taws xob thiab qhov hluav taws xob rov ua dua los ntawm cov hluav taws xob sab nraud, ua ib qho tam sim no, yog li ua tiav cov kev hloov pauv ntawm lub teeb rau hauv hluav taws xob hluav taws xob.
Lub ntsiab tseem ceeb ntawm lub hnub ci vaj huam sib luag yog lub hnub ci cell, uas feem ntau yog ua los ntawm monocrystalline silicon los yog polycrystalline silicon. Monocrystalline silicon hlwb muaj kev hloov dua siab tshiab dua tab sis kuj kim dua; thaum polycrystalline silicon hlwb tsis tshua kim, tab sis lawv cov kev hloov pauv tau qis dua li ntawm monocrystalline silicon. Dhau li ntawm silicon-raws li hnub ci hlwb, tseem muaj nyias- zaj duab xis hnub ci, xws li tooj liab indium gallium selenide (CIGS) thiab cadmium telluride (CdTe) hlwb. Cov no yog cov yam ntxwv ntawm lawv cov thinness, lub teeb yuag, thiab yoog raws, ua rau lawv haum rau cov kev siv tshwj xeeb.
Lub zog tsim hluav taws xob ntawm lub hnub ci vaj huam sib luag yog cuam tshuam los ntawm ntau yam, suav nrog lub teeb siv, spectral faib, kub, thiab shading. Txhawm rau txhim kho kev ua tau zoo, cov hnub ci vaj huam sib luag feem ntau yog tsim los nrog cov kaum ntse ntse tshwj xeeb thiab kev taw qhia kom ua kom lub hnub ci tau txais kev pom zoo. Tsis tas li ntawd, qee qhov kev tshaj lij hnub ci vaj huam sib luag siv cov txheej txheem taug qab uas kho lawv lub kaum ntse ntse hauv lub sijhawm raws li lub hnub txoj haujlwm txhawm rau txhim kho kev ua tau zoo.
Hais txog kev siv, cov hnub ci vaj huam sib luag tau siv dav hauv cov tsev nyob, cov tsev lag luam, cov chaw tsim khoom, thiab cov khoom siv hluav taws xob hauv thaj chaw deb. Hauv thaj chaw nyob, cov hnub ci vaj huam sib luag tuaj yeem ntsia tau rau ntawm lub ru tsev los muab cov hluav taws xob huv, rov ua dua tshiab rau cov tsev. Hauv kev lag luam thiab kev lag luam, loj - cov chaw tsim hluav taws xob hnub ci tuaj yeem muab kev txhawb zog ruaj khov rau kev lag luam, txo cov nqi hluav taws xob. Hauv thaj chaw deb, cov hnub ci vaj huam sib luag yog ib txoj hauv kev zoo los daws cov teeb meem hluav taws xob.
Nrog kev txhim kho thev naus laus zis tas mus li, kev hloov pauv kev ua haujlwm ntawm lub hnub ci vaj huam sib luag tau txhim kho tas li, thiab cov nqi tau maj mam txo qis, ua rau lub hnub ci zog muaj kev sib tw zog ntxiv. Nyob rau hauv lub neej yav tom ntej, nrog rau txoj kev loj hlob ntawm ntse daim phiaj thiab lub zog cia technologies, hnub ci vaj huam sib luag yuav ua si ib tug tseem ceeb luag hauj lwm nyob rau hauv lub zog sector, txhawb kev hloov thiab kev loj hlob ntawm lub ntiaj teb no lub zog qauv.
