Composition Of Solar Vaj Huam Sib Luag
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 yuav tseem yog cov khoom tseem ceeb ntawm lub hnub ci hnub ci mus ntev.
Lub tshuab tsim cov khoom siv polysilicon tau ntev lawm nyob rau hauv tes ntawm 10 factories ntawm 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 tug teeb meem ntawm technology blockade 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 tuaj yeem muab faib ua qib hluav taws xob thiab qib hnub ci. Ntawm lawv, qib hluav taws xob polysilicon suav txog li 55 feem pua, thiab hnub ci qib polysilicon suav txog 45 feem pua.
Nrog txoj kev loj hlob sai ntawm kev lag luam photovoltaic, qhov kev loj hlob ntawm kev thov rau polysilicon los ntawm lub hnub ci hlwb yog siab dua li ntawm semiconductor polysilicon. Nws tau kwv yees tias qhov kev thov rau hnub ci polysilicon yuav dhau ntawm cov qib hluav taws xob polysilicon los ntawm 2008.
Xyoo 1994, tag nrho cov txiaj ntsig ntawm lub hnub ci hauv ntiaj teb tsuas yog 69MW, thaum 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 nuclear ua ib qho tseem ceeb tshaj plaws ntawm lub zog hluav taws xob hauv thawj ib nrab ntawm lub xyoo pua 21st.
