Enhancement of dye-sensitized solar cell (DSSC) performance using polymeric spectacular reflectance film

Abstract

Photoconversion efficiency of the DSSC was enhanced by simple process which reuse the light passing through the cell. Flexible polymeric spectacular reflectance film which is z-direction index matched multilayer stack was directly attached on the exterior of Pt counter electrode. Overall photoconversion efficiency increased from 7.0% to 7.8% and the incident photon to current currency curve showed increase in the entire spectral range from DSSC with polymeric spectacular film.
