Cov yam ntxwv tseem ceeb ntawm Solar Cells

Cov yam ntxwv tseem ceeb ntawm lub hnub ci muaj xws li polarity ntawm lub hnub ci hlwb, qhov ua haujlwm tsis zoo ntawm lub hnub ci hlwb, thiab cov yam ntxwv volt ampere ntawm lub hnub ci ib puag ncig cov roj teeb. Cov lus piav qhia tshwj xeeb yog raws li hauv qab no
1. Polarity ntawm lub hnub ci hlwb
Silicon solar cells feem ntau ua rau P + / N hom qauv lossis N + / P hom qauv, qhov twg P + thiab N + sawv cev rau cov khoom siv hluav taws xob ntawm cov khoom siv hluav taws xob nyob rau hauv pem hauv ntej lub teeb txheej ntawm lub hnub ci cell; N thiab P sawv cev rau hom conductive ntawm cov khoom siv semiconductor nyob rau sab nraum qab ntawm lub hnub ci cell substrate. Kev ua haujlwm hluav taws xob ntawm lub hnub ci hlwb muaj feem xyuam nrog cov yam ntxwv ntawm cov khoom siv semiconductor siv hauv kev tsim cov roj teeb.
2. Kev ua haujlwm tsis zoo ntawm lub hnub ci hlwb
Kev ua haujlwm tsis zoo ntawm lub hnub ci hlwb yog tsim los ntawm kev qhib hluav taws xob hluav taws xob, luv Circuit Court tam sim no, qhov siab tshaj plaws tso zis hluav taws xob, kev ua kom tiav, kev hloov pauv hloov pauv, thiab lwm yam.
3.Volt ampere yam ntxwv ntawm 3 hnub ci hlwb
PN hlws ris hnub ci cell muaj ib tug ntiav PN hlws ris tsim nyob rau saum npoo, ib tug sawb thiab ntiv tes zoo li pem hauv ntej ohmic kev sib cuag, ib tug rov qab ohmic kev sib cuag npog tag nrho cov sab nraub qaum, thiab ib tug anti reflective txheej nyob rau hauv pem hauv ntej. Thaum lub roj teeb raug rau lub hnub ci spectrum, photons nrog lub zog tsawg dua qhov dav bandgap Piv txwv li tsis ua rau lub roj teeb tso tawm. Photons nrog lub zog ntau dua li qhov dav bandgap Eg pab txhawb lub zog Eg rau lub roj teeb tso zis, thaum lub zog tsawg dua Eg yog siv rau hauv daim ntawv ntawm tshav kub. Yog li ntawd, hauv kev tsim thiab tsim cov txheej txheem ntawm lub hnub ci, nws yog ib qho tsim nyog yuav tsum xav txog qhov cuam tshuam ntawm cov cua sov no ntawm kev ruaj ntseg, lub neej ntev, thiab lwm yam ntawm lub roj teeb.
