Presentation Summary

  • Formation of microsized aggregates of ZnO nanocrystallites or TiO2 nanotubes by means of solution processing.
  • Significant enhancement of power conversion efficiency (~300%) through effective light scattering by microsized aggregates while retaining desired specific surface area for dye molecule adsorption.
  • Power conversion efficiency higher than 11% is anticipated when the popcorn structure and surface chemistry is successfully optimized.
