Lub hnub ci ntsa ntawm Semiconductor PN kev sib tshuam, ua lub qhov tshiab-tshuab hluav taws xob tshiab. Nyob rau hauv qhov kev txiav txim ntawm hluav taws xob teb ntawm PN kev sib tw, lub qhov ntws los ntawm N Cheeb Tsam, thiab cov hluav taws xob ntws tawm ntawm N thaj chaw mus rau PA cheeb tsam. Thaum lub Circuit Court txuas nrog, tam sim no yog tsim. Ntawd yog li cas Photoelectric cuam tshuam hnub ci hlwb ua haujlwm.
Hnub ci zog yog ob hom kev hloov hluav taws xob, ib qho yog qhov hloov hluav taws xob hloov hluav taws xob-hloov hluav taws xob ncaj qha.
(1) Lub teeb hluav taws xob-hluav taws xob cua sov siv cov hluav taws xob thermal tsim los ntawm hnub ci hluav taws xob los tsim hluav taws xob. Feem ntau, cov nqus hluav taws xob nqus hluav taws xob hloov pauv mus rau hauv chav ua haujlwm nruab nrab los ntawm lub hnub ci ua haujlwm los ntawm lub hnub ci tshiab yog tsav rau cov hluav taws xob. Cov txheej txheem qub yog teeb txheej txheem hloov pauv kub; Cov txheej txheem tom kawg yog cov cua sov - cov txheej txheem hloov hluav taws xob.
(2) Cov nyhuv duab yees siv tau siv los hloov lub hnub ci hluav taws xob hluav taws xob ncaj qha rau hauv hluav taws xob lub zog. Cov cuab yeej yooj yim ntawm kev hloov pauv lub yees siv yees duab yog lub nruab hnub ci. Hnub ci cell yog lub cuab yeej uas hloov dua siab lug hnub ci lub zog rau hauv hluav taws xob hluav taws xob nyhuv. Nws yog semiconductor photodiode. Thaum lub hnub ci ntsa iab ntawm lub photodiode, lub photodiode yuav tig lub hnub ci lub zog rau hauv lub zog hluav taws xob thiab tsim kom muaj lub zog hluav taws xob thiab tsim kom muaj lub zog hluav taws xob thiab tsim kom muaj lub zog hluav taws xob thiab tsim kom muaj lub zog hluav taws xob. Thaum muaj ntau lub hlwb txuas nrog hauv cov koob los yog hauv parallel, square array ntawm cov hlwb hnub ci nrog cov zis loj tuaj yeem tsim tau.
Tam sim no, crystalline silicon (suav nrog polysilicon thiab monocrystalline silicon) yog cov ntaub ntawv tseem ceeb tshaj plaws, nws cov khoom lag luam yog ntau dua li 90%, thiab yav tom ntej rau lub sijhawm ntev dua tseem yuav yog cov ntaub ntawv tseem ceeb ntawm cov hnub ci.
Tau ntev heev, cov thev naus laus zis ntau lawm ntawm cov ntaub ntawv polysilicon tau raug tswj hwm los ntawm 7 lub tuam txhab hauv 3 lub teb chaws, Nyiv thiab lub teb chaws huab cua thiab kev ua lag luam Monopoly.
Cov neeg xav tau polysilicon feem ntau yog los ntawm semiconductors thiab lub hnub ci hlwb. Raws li cov kev xav txawv txawv, muab faib ua hluav taws xob qib thiab theem hnub. Ntawm lawv, hluav taws xob-qib polysilicon account txog li 55%, qib hnub polysilicon nyiaj rau 45%.
Nrog rau kev loj hlob sai ntawm photovoltaic, qhov kev thov rau polysilicon hauv cov polysilicon, thiab nws yuav tsum tau ua rau hnub ci polysilicon los ntawm 2008.
Xyoo 1994, tag nrho cov khoom siv ntawm cov hlwb ci ntsa iab hauv lub ntiaj teb tsuas yog 69mw, tab sis xyoo 2004 nws tau nyob ze 12 xyoo. Cov kws tshaj lij twv tau hais tias kev lag luam photoHovoltoltoltotic yuav dhau los ua ib qho tseem ceeb tshaj plaws hauv thawj ib nrab ntawm lub xyoo pua 21st.
