Improvement of Dye-Sensitized Solar Cells Using Hollow ZnO Nanorices

Abstract:

The photoanodes of dye-sensitized solar cells (DSSCs) were studied. Industrial TiO2 nanoparticles (P25) were used to form the active layer, and hollow ZnO nanoparticles (hollow ZnO) or ZnO powder particles were coated on top of the active layer to form the scattering layer. The hollow ZnO scattering layer helps increase the amount of dye adsorption as the surface area increases and the efficiency of incident light utilization due to high scattering characteristics. As a result, the light absorption of photoanodes with hollow ZnO was about 90% higher than that of DSSC with only TiO2 film and about 25% higher than that of DSSC with ZnO powder as a scattering layer.
