Lub vaj huam sib luag monocrystalline hnub ci yog kev sib dhos ntawm ntau lub hnub ci monocrystalline silicon hnub ci sib sau ua ke ntawm lub rooj tsavxwm hauv ib txoj kev. Lub photoelectric conversion efficiency ntawm monocrystalline silicon hnub ci hlwb yog li ntawm 15 feem pua, thiab qhov siab tshaj plaws mus txog 24 feem pua. Qhov no yog qhov zoo tshaj plaws photoelectric conversion efficiency ntawm txhua hom hnub ci hlwb, tab sis tus nqi ntau lawm yog li ntawd nws tsis tuaj yeem siv dav hauv ntau qhov ntau. siv av. Vim tias monocrystalline silicon feem ntau encapsulated nrog tempered iav thiab waterproof resin, nws yog ruaj thiab nws cov kev pab cuam lub neej feem ntau mus txog 15 xyoo, thiab qhov siab tshaj plaws yuav ncav cuag 25 xyoo. Nws feem ntau yog siv rau hauv kev tsim khoom thiab siv cov khoom siv hluav taws xob zoo hnub ci, thiab kev them nqi hloov pauv tau siab dua li ntawm polycrystalline solar panels.
Tam sim no, cov ntaub ntawv crystalline silicon (xws li polycrystalline silicon thiab monocrystalline silicon) yog cov ntaub ntawv tseem ceeb tshaj plaws photovoltaic, nrog rau kev lag luam feem ntau tshaj 90 feem pua, thiab tseem yuav yog cov khoom siv tseem ceeb rau lub hnub ci hnub ci rau lub sijhawm ntev yav tom ntej. . Lub tshuab tsim cov khoom siv polysilicon tau nyob rau hauv tes ntawm 10 lub tuam txhab ntawm 7 lub tuam txhab hauv 3 lub teb chaws suav nrog Tebchaws Meskas, Nyiv thiab Lub Tebchaws Yelemees tau ntev, tsim ib qho xwm txheej ntawm kev thaiv technology thiab kev lag luam monopoly. Qhov kev thov rau polysilicon feem ntau yog los ntawm semiconductors thiab hnub ci hlwb. Raws li cov kev cai purity sib txawv, nws muab faib ua qib hluav taws xob thiab qib hnub ci. Ntawm lawv, hluav taws xob-qib polysilicon suav txog li 55 feem pua, thiab hnub ci-qib polysilicon suav txog 45 feem pua. Nrog rau txoj kev loj hlob sai ntawm kev lag luam photovoltaic, qhov kev thov rau polysilicon rau lub hnub ci hlwb yog loj hlob sai dua li kev loj hlob ntawm semiconductor polysilicon. Kev thov yuav tshaj tawm cov khoom siv hluav taws xob-qib polysilicon. Xyoo 1994, tag nrho cov khoom tsim tawm ntawm lub hnub ci hauv ntiaj teb tsuas yog 69MW, tab sis xyoo 2004 nws tau ze rau 1200MW, nce 17 zaug hauv 10 xyoo xwb. Cov kws tshaj lij kwv yees tias kev lag luam hnub ci photovoltaic yuav dhau lub zog hluav taws xob los ua ib qho tseem ceeb tshaj plaws ntawm lub zog hluav taws xob hauv thawj ib nrab ntawm lub xyoo pua 21st.
