Probing novel photoanodes relying on CuBiSe/metal? oxides nanocomposites-based dye-sensitizing solar cells

CuBiSe / Metal oxides (TiO2, V2O5, and ZnO) nanocomposites were synthesized by a simple and low-cost hy-drothermal technique for application in Dye-Sensitised Solar Cells (DSSCs). XRD, XPS, SEM with EDX analysis, FTIR spectrum, UV visible Spectroscopy, PL spectrum, Hall Effect analysis, and Impedance analysis were per-formed to evaluate the prepared nanocomposites. The photovoltaic performance of DSSCs which were con-structed with CBS/ TiO2, CBS/V2O5, and CBS/ZnO photoanodes were investigated. With a short-circuit, photocurrent density of 3.728 mA cm2, an open circuit voltage of 0.398 V, a fill factor of 0.72, and a Power conversion efficiency (PCE) of 1.07% was achieved for CBS/V2O5 DSSCs device, which is greater than that of DSSCs devices using CBS/ TiO2 and CBS/ZnO based photo-anodes (PCE = 0.62, and 0.37%). The obtained results propose that the prepared nanocomposite is an appropriate photo-anodic material for DSSCs applications.

Automated summary

CuBiSe/metal oxide (TiO2, V2O5, and ZnO) nanocomposites were synthesized using a simple and low-cost hydrothermal technique for Dye-Sensitised Solar Cells (DSSCs) application. Various analyses including XRD, XPS, SEM with EDX, FTIR, UV-Visible Spectroscopy, PL spectrum, Hall Effect analysis, and Impedance analysis were performed to evaluate the nanocomposites. The photovoltaic performance of DSSCs with CBS/TiO2, CBS/V2O5, and CBS/ZnO photoanodes was investigated. The CBS/V2O5 DSSCs device demonstrated a short-circuit photocurrent density of 3.728 mA cm2, an open circuit voltage of 0.398 V, a fill factor of 0.72, and a power conversion efficiency (PCE) of 1.07%, higher than that of DSSCs using CBS/TiO2 and CBS/ZnO photoanodes (PCE = 0.62 and 0.37%). These results suggest that the prepared nanocomposite is a suitable photoanodic material for DSSCs applications.
