Voltage- and Power-Conversion Performance of Bi-functional ZrO : Er / Yb Assisted and Co-sensitized Dye Sensitized Solar Cells for Internet of Things Applications.

Giant power conversion efficiency is achieved by using bifunction ZrO  : Er /Yb assisted co-sensitised dye-sensitized solar cells. The evolution of the crystalline structure and its microstructure are examined by X-ray diffraction, scanning electron microscopy studies. The bi-functional behaviour of ZrO  : Er /Yb as upconversion, light scattering is confirmed by emission and diffused reflectance studies.

Enhanced Performance of Dye-Sensitized Solar Cells (DSSCs) Based on MoS /Single-Walled Carbon Nanohorns Electrochemically Deposited on Bilayer Counter Electrodes.

High-performance bilayer counter electrodes (BCEs) for dye-sensitized solar cell (DSSC) applications are gaining considerable attention. In this study, MoS /single-walled carbon nanohorn (SWCNHs) BCEs were fabricated by ultrasonic-spray-assisted electrochemical deposition. The BCEs exhibited superior electrocatalytic activity, confirmed through CV, Tafel plots, and electrochemical impedance spectroscopic studies.

Disintegration of Flower-Like MoS₂ to Limply Allied Layers on Spherical Nanoporous TiO₂: Enhanced Visible-Light Photocatalytic Degradation of Methylene Blue.

MoS₂/TiO₂ heterostructure with enhanced photocatalytic activity was successfully synthesized by hydrothermal method. The segmentation of flower-like MoS₂ structure resulted, during the hydrothermal condition in the presence of spherical nanoporous TiO₂ as a growing matrix. A pool of larger spherical TiO₂ particle induces a strain effect, which restricted the size of MoS₂.

Enhanced Visible Light Activity of Pr-TiO₂ Nanocatalyst in the Degradation of Dyes: Effect of Pr Doping and TiO₂ Morphology.

A facile hydrothermal method was adopted for the synthesis of bare TiO₂ and titania nanotubes (TNT). In an effort to increase the efficacy of the existing photocatalyst, different weight percentage (0.2, 0.

3D nanorhombus nickel nitride as stable and cost-effective counter electrodes for dye-sensitized solar cells and supercapacitor applications.

Transition metal nitride based materials have attracted significant interest owing to their excellent properties and multiple applications in the field of electrochemical energy conversion and storage devices. Herein we synthesize 3D nanorhombus nickel nitride (NiN) thin films by adopting a reactive radio frequency magnetron sputtering process. The as-deposited 3D nano rhombus NiN thin films were utilized as cost-effective electrodes in the fabrication of supercapacitors (SCs) and dye-sensitized solar cells (DSSCs).
