Power Generation Principple Of Solar Panel

Lub hnub ci rau ntawm lub semiconductor pn hlws ris, tsim ib lub qhov tshiab electron khub. Raws li qhov tshwm sim ntawm cov hluav taws xob hluav taws xob ntawm pn kev sib tshuam, qhov ntws los ntawm thaj av p mus rau thaj tsam n, thiab cov hluav taws xob ntws los ntawm thaj av n mus rau thaj tsam p. Tom qab lub voj voog txuas nrog, ib qho tam sim no raug tsim. Qhov no yog lub hauv paus ntsiab lus ua haujlwm ntawm photoelectric effect solar cells.

Hnub ci tsim hluav taws xob Muaj ob txoj hauv kev tsim hluav taws xob hnub ci, ib qho yog lub teeb hluav taws xob hloov hluav taws xob, lwm qhov yog lub teeb hluav taws xob ncaj qha hloov pauv.

(1) Lub teeb hluav taws xob hloov hluav taws xob siv hluav taws xob siv hluav taws xob hluav taws xob tsim los ntawm hnub ci hluav taws xob los tsim hluav taws xob. Feem ntau, lub hnub ci collector hloov cov hluav taws xob nqus hluav taws xob mus rau hauv chav ua haujlwm nruab nrab, thiab tom qab ntawd tsav lub tshuab hluav taws xob los tsim hluav taws xob. Cov txheej txheem qub yog cov txheej txheem hloov hluav taws xob lub teeb; Cov txheej txheem tom kawg yog cov txheej txheem thermal hloov hluav taws xob.

(2) Photoelectric hloov dua siab tshiab yog ncaj qha hloov lub hnub ci hluav taws xob rau hauv hluav taws xob hluav taws xob los ntawm kev siv cov nyhuv photoelectric. Cov cuab yeej siv yooj yim ntawm kev hloov pauv photoelectric yog hnub ci cell. Hnub ci cell yog ib qho cuab yeej uas ncaj qha hloov lub hnub ci zog rau hauv hluav taws xob vim yog cov nyhuv photovoltaic. Nws yog semiconductor photodiode. Thaum lub hnub ci rau ntawm lub photodiode, lub photodiode yuav hloov lub hnub ci zog rau hauv hluav taws xob hluav taws xob thiab tsim cov tam sim no. Thaum muaj ntau lub hlwb txuas nrog hauv series lossis nyob rau hauv tib lub sijhawm, lawv tuaj yeem dhau los ua lub hnub ci cell array nrog cov khoom siv hluav taws xob loj.
