Morphological modification of CdSe_0.6Te_0.4 nanostructures by electron irradiation and the effect on photoelectrochemical cells

Morphologically well-ordered synthesis of nanomaterials by modification simple and cost effective. Electron irradiation is a promising pathway to develop various nanostructured materials. We report on the successful fabrication of hierarchical CdSe_0.6Te_0.4 nanostructures (nanonests, nanobrick-like small spheres with hybrid nanostructure, marigold, and nanoflowers) by electron beam irradiation in electrodeposition. These CdSe_0.6Te_0.4 nanostructures were employed as electrode material in solar cells, and the relationship between photoelectrochemical properties and CdSe_0.6Te_0.4 nanostructures was investigated, and showed that the photoelectrochemical properties strongly depend on CdSe_0.6Te_0.4 nanostructure morphology. The power conversion efficiency for nanonests, nanobrick-like small spheres with hybrid nanostructure, marigold, and nanoflowers of CdSe_0.6Te_0.4 were 0.88, 0.71, 1.03, and 0.94 %, respectively.
