title: Simple approach for enhancement of light harvesting efficiency of dye-sensitized solar cells by polymeric mirror.
abstract: A Polymeric mirror from 1D photonic crystal exhibiting full specular reflection is applied on the exterior of the counter electrode of a dye-sensitized solar cells (DSSCs). Reflection of exiting light from the cell allows for the reuse of the light and thereby significantly increases the efficiency of the DSSCs (from 8.07% to 8.85%). Furthermore, it is also found to be effective even with incorporation of an internal scattering layer, which is widely used within a TiO₂ anode layer for enhancing light trapping in DSSCs (from 9.17% to 9.53%).
