Synthesis of Flower-Like Graphene Doped Cobalt Oxide via Hydrothermal Method and Its Performance as Counter Electrode in Dye Sensitized Solar Cells Applications

Hierarchical pompon-like cobalt phosphide as a platinum-free electrocatalyst for dye-sensitized solar cells

“…In recent years, extensive studies have focused on the synthesis of micro-/nano-structured electrocatalysts [1][2][3][4] with an intention to accelerate a rate-determining step, i.e., the redox reaction of mediators, in dye-sensitized solar cells (DSSCs) using earth abundant materials. Many high performance electrocatalysts have been designed to possess various micro-/nanostructures, including rod/tube/torch-like (1D), [5][6][7] urchin-like (1D), 8,9 sheet-like (2D), [10][11][12] ball/yolk-shell-like (3D), 13,14 and flower-like (3D) 15,16 particles. However, the dramatic increasing demands on the performance of electrocatalysts drove many researchers to find the advanced materials simultaneously having large electrochemical active surface area, high conductivity, and low cost.…”
