Role of natural dye in photovoltaic performance of dye-sensitized solar cell

Abstract

Investigating cost-effective alternatives to organic dyes for use in dye-sensitized solar cells (DSSC) could help lower the devices' overall cost. This manuscript deals with the optical and structural properties of novel natural Dye extracted from harda fruit. The optical absorbance, emission, and functional group of natural Dye have been studied using UV–vis. Spectroscopy, photoluminescence, and Fourier transform infrared (FTIR), respectively. The DSSC has been fabricated using natural Dye as a photo-sensitizer and studied their photovoltaic performance. The power conversion efficiency (PCE) for DSSC has been achieved up to 2.7%. Although the use of natural Dye in DSSC improved the short-circuit current density (Jsc) and open-circuit voltage (Voc). Understanding these fundamental properties of natural Dye could pave the way for developing natural dyes-based solar cells.
