Synthesis of One-Dimensional Bismuth Sulfide Nanoparticle with Enhanced Photovoltaic Properties

Bismuth sulfide is a promising n-type semiconductor for solar energy conversion. In this work, we have successfully synthesized bismuth sulfide nanoparticles (Bi2S3 NPs)] from [Bi(ACDA)3] complex. The as-synthesized particles were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), and UV-vis spectroscopy. The prepared material exhibits a high absorbance coefficient, a low bandgap, and good disparity. Thus, prepared Bi2S3 material provides a new candidate for the fabrication of environmentally friendly and low-cost inorganic hybrid solar cells.
