Khoom siv ntawm ib lub hnub ci vaj huam sib luag

Tam sim no, crystalline silicon cov ntaub ntawv (xws li polycrystalline silicon thiab ib qho siv lead ua silicon) yog cov ntaub ntawv tseem ceeb tshaj plaws photovoltaic, thiab lawv cov kev lag luam feem ntau yog ntau tshaj 90%, thiab lawv tseem yuav yog cov ntaub ntawv tseem ceeb rau lub hnub ci hnub ci rau lub sijhawm ntev tuaj. Polysilicon cov khoom siv technology tau ntev lawm nyob rau hauv tes ntawm 10 tuam txhab uas muag nyob rau hauv 7 tuam txhab uas muag nyob rau hauv 3 lub teb chaws, xws li lub tebchaws United States, Nyiv, thiab lub teb chaws Yelemees, tsim ib lub xeev ntawm technologies blockade thiab ua 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, 55% yog siv rau qib hluav taws xob polysilicon, thiab 45% yog siv rau hnub ci qib polysilicon. Nrog rau kev loj hlob sai ntawm kev lag luam photovoltaic, qhov kev loj hlob ntawm polysilicon thov rau lub hnub ci hlwb yog siab dua li ntawm semiconductor polysilicon. Kev thov yuav ntau dua qib hluav taws xob polysilicon. Xyoo 1994, tag nrho cov khoom tsim tawm ntawm lub hnub ci hauv ntiaj teb tsuas yog 69MW, thiab xyoo 2004 nws tau ze rau 1200MW, uas tau 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 nuclear ua ib qho tseem ceeb tshaj plaws ntawm lub zog hluav taws xob hauv thawj ib nrab ntawm lub xyoo pua 21st.
