Defects and impurities in solar-grade silicon and multicrystalline silicon wafers

  • The effect of transition metal impurities such as Fe, Cr, Ni and Cu on solar cell performance.
  • Studying the relative recombination activity of dissolved or precipitated metals.
  • Removal, or 'gettering', of metallic impurities such as Fe by heavily doped surface diffusions.
  • Studying the impact of hydrogenation on dissolved and precipitated metals, and on crystal defects such as dislocations and grain boundaries.
