Cov yam ntxwv tseem ceeb ntawm Solar Cells

Cov yam ntxwv tseem ceeb ntawm lub hnub ci hlwb suav nrog peb tus yam ntxwv tseem ceeb: lub polarity ntawm lub hnub ci hlwb, kev ua haujlwm tsis zoo ntawm lub hnub ci, thiab cov yam ntxwv volt-ampere ntawm hnub ci hluav taws xob ib puag ncig tiv thaiv hlwb. Cov lus piav qhia tshwj xeeb yog raws li hauv qab no
1. Polarity ntawm lub hnub ci hlwb
Lub hnub ci silicon feem ntau yog ua los ntawm P plus / N hom qauv lossis N ntxiv / P hom qauv, P ntxiv thiab N ntxiv, qhia txog cov khoom siv hluav taws xob semiconductor nyob rau hauv pem hauv ntej lub teeb txheej ntawm lub hnub ci cell; N thiab P, qhia txog cov khoom siv hluav taws xob ntawm cov khoom siv hluav taws xob sab nraum qab ntawm lub hnub ci cell. Cov khoom 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 hnub ci hlwb.
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 qhov qhib-circuit voltage, luv-circuit tam sim no, siab tshaj plaws tso zis zog, filling factor, conversion efficiency, thiab lwm yam.
3 Volt-ampere yam ntxwv ntawm lub 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 tus pem hauv ntej ohmic sib cuag, ib tug rov qab ohmic contact 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 li qhov sib txawv ntawm qhov dav ntawm qhov sib txawv xws li tsis muaj kev txhawb nqa rau lub roj teeb tso zis. Photons nrog lub zog ntau dua li qhov sib txawv ntawm qhov dav Eg yuav ua rau lub zog Eg rau lub roj teeb tso zis, thiab lub zog tsawg dua Eg yuav raug siv rau hauv daim ntawv ntawm tshav kub. Yog li ntawd, nyob rau hauv kev tsim thiab tsim cov txheej txheem ntawm lub hnub ci hlwb, qhov cuam tshuam ntawm qhov no ntawm cov cua sov ntawm kev ruaj ntseg thiab lub neej ntawm cov hlwb yuav tsum tau xav txog.
