Study of Different Natural Dyes for Dye‐Sensitized Solar Cell

Abstract

In this paper extract of pomegranate, beet root and black berry are used to study the performance of these dyes on the DSSCs. The UV‐vis spectra of natural dyes suggest that pomegranate and blackberry have a better absorptive capacity at 300–550 nm, which is attributed to higher concentration of pigment with anthocyanin. From the overall study of natural dyes, it is observed that the blackberry exhibits optimal performance and power conversion efficiency reaches up to 0.160% due to higher absorption coefficient as compared to other natural dyes under study.

“…[4][5][6] The main function of a photoanode is to absorb photon energy, complete the energy level transition of the semiconductor material, oxidize the electrolyte and produce charged electrons; the role of the CE is to reduce the oxidized electrolyte and collect the external circuit electrons. [7][8][9] High-performance CEs can produce DSSCs with high PCE; CEs with excellent performance should have good catalytic ability for the reduction of the electrolyte so as to accelerate the redox reaction of the electrolyte. They also need to have good conductivity and be able to conduct electrons better.…”
