Improvement of Dye-Sensitized Solar Cell Performance via Addition of Azopyridine Derivative in Polymer Gel Electrolytes

Year: 2024

Type: article

Abstract: In this study, a polymer gel electrolyte based on polyacrylonitrile was synthesized with varying polymer-to-liquid-electrolyte ratios. DSSCs incorporating a 1:3 ratio showed optimum PV parameters. Choosing this proportion, the effect of incorporating the photoresponsive AZO dye into this polymer electrolyte was studied. When irradiated with a UV light of 365 nm, the AZO dye underwent photoisomerization, which allowed the gel electrolyte to absorb heat from the UV irradiation and increase its ionic conductivity. It was found that by the addition of azopyridine into the polymer electrolyte, there was an improvement in the photovoltaic parameters of cells. By increasing the dye content from 1% to 10% by weight in the electrolyte, an 11% growth in short current density was observed, resulting in about a 10% rise in cell efficiency.
