Dye-Sensitized Solar Cells Based on High Surface Area Nanocrystalline Zinc Oxide Spheres

الملخص EN

High surface area nanocrystalline zinc oxide material is fabricated using mesoporous nanostructured carbon as a sacrificial template through combustion process.

The resulting material is characterized by XRD, N2 adsorption, HR-SEM, and HR-TEM.

The nitrogen adsorption measurement indicates that the materials possess BET specific surface area ca.

30 m2/g.

Electron microscopy images prove that the zinc oxide spheres possess particle size in the range of 0.12 μm–0.17 μm.

The nanocrystalline zinc oxide spheres show 1.0% of energy conversion efficiency for dye-sensitized solar cells.
