Enhanced Efficiency of TaON and BiOI-based Solar Cells by Au Nanoparticles
Keywords:Au, TaON, BiOI, Composite, Solar cell.
Au nanoparticles were prepared by a chemical reduction method and were deposited on TaON nanoparticle or BiOI microsphere to prepare the composites of Au/TaON or Au/BiOI, respectively. The composites of Au/TaON and Au/BiOI were analyzed by UV-visible spectroscopy, XRD, and EDX. The films of these nanocomposites were prepared by a squeeze method and were applied to solar cell where Pt film was used as counter electrode. A water based solution of Ce3+/Ce4+ was used as an electrolyte. It was found that Au deposited TaON or BiOI film shows higher current (I)-voltage (V) curve under UV-visible light irradiation.
Key words: Au; TaON; BiOI; Composite; Solar cell.
