Herein, we report bismuth sulfide (Bi2S3) synthesis via the hydrothermal method for low-cost dye-sensitized solar cell (DSSCs). A detailed characterization of Bi2S3/poly (vinylpyrrolidone) (PVP) material was carried out by various characterization technique. The J–V curves and cyclic voltammogram were examined using a solar simulator to evaluate power conversion efficiency (PCE) and its catalytic activities. The experiment was then repeated with a different amount of PVP agent surfactant to improve their power conversion efficiency. With the help of 1.0 g PVP, its conversion efficiency reached 3.35%, which was superior to the Bi2S3 without PVP addition. The results indicate that the Bi2S3/1.0 g PVP composites is a promising alternative to the costly Pt CE and can minimize the cost of dye-sensitized solar cells. © 2023 Korean Physical Society
