1. Raws li peb txhua tus paub, lub hnub ci hluav taws xob yog lub zog tseem ceeb tshaj plaws hauv lub zog tauj dua tshiab thiab lub zog huv, thiab ntau lub teb chaws thoob ntiaj teb tab tom kawm txog kev hloov dua siab tshiab thiab siv lub hnub ci zog. Kev hloov pauv ntawm lub hnub ci zog rau hauv lub zog hluav taws xob los ntawm kev hloov pauv khoom siv yog lub hnub ci thermal siv thev naus laus zis, thiab kev siv lub zog hluav taws xob rau lub zog hluav taws xob yog hu ua hnub ci thermal zog tsim; Kev siv lub hnub ci zog rau hauv hluav taws xob hluav taws xob belongs rau lub hnub ci hluav taws xob tsim tshuab, uas feem ntau hloov pauv los ntawm cov nyhuv photovoltaic (uas yog, cov nyhuv photovoltaic) ntawm cov khoom siv semiconductor, yog li nws tseem hu ua hnub ci photovoltaic thev naus laus zis, thiab cov cuab yeej uas hloov lub hnub ci zog. rau hauv hluav taws xob hluav taws xob yog hu ua solar panels lossis photovoltaic panels.

2. Kom paub seb lub hnub ci vaj huam sib luag hloov lub hnub ci rau hauv hluav taws xob li cas, kuv yuav tsum xub nkag siab tias PN junction yog dab tsi. Cov khoom siv semiconductor siv los ua cov hnub ci vaj huam sib luag yog ib yam khoom tshwj xeeb ntawm cov conductors thiab insulators, semiconductor atoms yog tsim los ntawm cov nuclei zoo thiab cov hluav taws xob tsis zoo, thiab txheej txheej ntawm semiconductor silicon atoms muaj 4 electrons, rotating ib ncig ntawm lub nucleus raws li ib tug taag. taug qab. Thaum raug rau lub zog extraneous, cov electrons deorbit thiab ua dawb electrons, tawm hauv "lub qhov" nyob rau hauv lawv thawj txoj hauj lwm. Nyob rau hauv cov ntshiab silicon crystals, tus naj npawb ntawm cov electrons dawb thiab qhov sib npaug. Yog tias siv lead ua silicon doped nrog boron, gallium thiab lwm yam khoom uas tuaj yeem cuam tshuam cov hluav taws xob, nws dhau los ua lub qhov-hom semiconductor, feem ntau qhia los ntawm lub cim "p"; Yog hais tias cov ntsiab lus xws li phosphorus thiab arsenic tau koom ua ke uas tuaj yeem tso cov hluav taws xob, nws dhau los ua ib qho hluav taws xob semiconductor, sawv cev los ntawm lub cim "N". Yog tias ob lub semiconductors sib xyaw ua ke, lawv qhov kev sib tshuam ua rau PN kev sib tshuam.

PN ntu hauv cov nyhuv photovoltaic

Yog li, ua li cas lub hnub ci vaj huam sib luag hloov hnub ci zog rau hauv hluav taws xob?

PN kev sib tshuam yog zoo li phab ntsa uas thaiv kev txav ntawm electrons thiab qhov. Thaum lub hnub ci vaj huam sib luag raug tshav ntuj, cov hluav taws xob tau txais lub zog hluav taws xob thiab txav mus rau thaj tsam N-hom, ua rau thaj tsam N-hom tsis zoo, thaum lub qhov txav mus rau thaj tsam P-hom, ua rau thaj tsam P-hom zoo. raug nqi. Nyob rau hauv no txoj kev, ib tug voltage yog generated thoob plaws PN hlws ris. Qhov tshwm sim no yog cov lus hais saum toj no "photovoltaic effect". Yog tias lub sijhawm no nws nyob hauv P-type txheej thiab N-hom txheej feem

solder cov hlau hlau, tig rau lub load, thiab tom qab ntawd lub sab nraud Circuit Court muaj tam sim no los ntawm nws. Nyob rau hauv txoj kev no, ib qho hluav taws xob thiab tam sim no tuaj yeem tsim tawm, uas yog, lub zog tso zis tuaj yeem tsim los hloov lub hnub ci zog rau hauv hluav taws xob. Muaj ntau tshaj li kaum ob lub npe hu ua semiconductor cov ntaub ntawv rau kev tsim cov hnub ci vaj huam sib luag, thiab cov thev naus laus zis tam sim no yog cov paub tab tshaj plaws.
