Thaum tshav ntuj ci rau ntawm lub semiconductor pn hlws ris, qhov tshiab-electron khub yog tsim. Nyob rau hauv qhov kev txiav txim ntawm lub built-in hluav taws xob teb ntawm lub pn hlws ris, qhov ntws los ntawm lub n cheeb tsam mus rau lub p cheeb tsam, thiab electrons ntws los ntawm lub p cheeb tsam mus rau lub n cheeb tsam. Thaum lub Circuit Court txuas, tam sim no yog tsim. Qhov no yog lub hauv paus ntsiab lus ua haujlwm ntawm photovoltaic nyhuv solar cell.
Muaj ob txoj hauv kev los tsim lub hnub ci zog: ib qho yog txoj kev hloov pauv lub teeb-kub-hluav taws xob, thiab lwm yam yog txoj kev hloov hluav taws xob ncaj qha-hluav taws xob.
(1) Txoj kev hloov lub teeb-kub-tsim hluav taws xob tsim hluav taws xob los ntawm kev siv lub zog hluav taws xob uas tsim los ntawm hnub ci hluav taws xob. Feem ntau, lub hnub ci collector hloov cov hluav taws xob nqus hluav taws xob mus rau hauv cov dej ua haujlwm, uas tom qab ntawd tsav lub tshuab hluav taws xob los tsim hluav taws xob. Cov txheej txheem yav dhau los yog lub teeb-kub hloov pauv txheej txheem; cov txheej txheem tom kawg yog cov txheej txheem hloov hluav taws xob hluav taws xob, uas yog tib yam li kev tsim hluav taws xob thermal zoo tib yam. Qhov tsis zoo ntawm lub hnub ci thermal fais fab yog qhov ua haujlwm qis thiab tus nqi siab. Nws yog kwv yees tias nws cov peev nyiaj tsawg kawg yog 5 mus rau 10 npaug kim dua li cov nroj tsuag thermal zoo tib yam.
(2) Direct light-electricity conversion method Txoj kev no siv cov nyhuv photovoltaic los hloov lub hnub ci hluav taws xob ncaj qha rau hauv hluav taws xob hluav taws xob. Cov cuab yeej siv yooj yim rau kev hloov hluav taws xob hluav taws xob yog lub hnub ci cell. Lub hnub ci hlwb yog cov khoom siv uas hloov lub hnub ncaj qha mus rau hauv hluav taws xob vim yog cov nyhuv photovoltaic. Lawv yog cov semiconductor photodiodes. Thaum lub hnub ci ci rau ntawm photodiode, lub photodiode hloov lub hnub ci mus rau hauv hluav taws xob hluav taws xob thiab tsim tam sim no. Thaum muaj ntau lub hlwb txuas nrog hauv series lossis nyob rau hauv tib lub sijhawm, lawv tuaj yeem tsim lub hnub ci cell array nrog lub zog tso zis ntau. Hnub ci hlwb yog ib qho kev cog lus tshiab lub zog nrog peb qhov zoo: kev ruaj khov, huv thiab yooj. Hnub ci hlwb muaj lub neej ntev. Raws li ntev raws li lub hnub muaj, lub hnub ci hlwb tuaj yeem siv tau ntev nrog kev nqis peev ib zaug. Piv nrog rau kev tsim hluav taws xob thermal thiab tsim hluav taws xob nuclear, lub hnub ci hlwb tsis ua rau muaj kuab paug ib puag ncig.
