Uthini umgaqo wokuguqula amandla elanga abe ngamandla ahlukeneyo?

Umgaqo wokuguqula amandla elanga abe ngamandla ahlukeneyo kukuba: amandla okukhanya avuselela ii-electron ukuvelisa amandla ombane; intshukumo yee-electron zenza umsinga wombane, ngaloo ndlela iguqula amandla okukhanya abe ngamandla ombane.

Inkqubo yokuguqula amandla elanga kumandla ombane kuthiwa yi-photovoltaic power generation. Umgaqo wokuvelisa amandla e-photovoltaic kukusebenzisa i-photons ekukhanyeni kwelanga ukuvuyisa ii-electron kwiiseli ze-photovoltaic ukuvelisa ngoku. Iseli ye-photovoltaic sisixhobo se-semiconductor esihlala siqulunqwe ngee-wafers ezininzi ze-silicon.

I-silicon wafer iqulethe izinto ezimbini, i-silicon-doped silicon kunye ne-silicon ye-boron-doped, enezakhiwo ezahlukeneyo ze-elektroniki. Xa ukukhanya kwelanga kubetha i-silicon wafer, iiphotons zibetha ii-electron kwi-silicon wafer, zichwayitisa kwii-athom zazo kwaye zenze iiperi ze-electron-hole kwiwafer. I-silicon efakwe kwi-phosphorus yi-n-type semiconductor, kunye ne-silicon efakwe kwi-boron yi-p-type semiconductor. Xa ezi zimbini zixhunyiwe, intsimi yombane yenziwe, kwaye intsimi yombane ibangela ukuba i-electron ihambe kwaye yenze i-current.

Uthini umahluko phakathi kweeseli zelanga ze-IBC kunye neeseli eziqhelekileyo zelanga (3)
