• RIE textured black silicon

  • A novel texturization process has been developed to produce black silicon (silicon surface with very low reflectivity). Inverted pyramid textured surface and very rough surface can be produced by controlling the plasma process parameter. Reflectivity le ... Read More

  • Silicon texturization with low surface damage

  • Low surface defect density of the textured crystalline silicon has been attained with appropriate wet chemical processing. The passivation quality was poor after the texturiation steps resulting less than 10 μs minority carrier lifetime with hydro ... Read More
  • Silicon texturization with low surface damage
  • Ultra-thin silicon PV solar cells

  • The light trapping mechanisms to mitigate reduction in absorption and improved passivation for the 10 μm thick silicon wafers were investigated in this study. A novel method to fabricate a high efficiency solar cell on a 10 μm thick silicon membrane ... Read More
