Abstract:
Iron nickel cobalt selenides are synthesized through a one-step hydrothermal method. Quaternary Fe0.37 Ni0.17 Co0.36 Se demonstrates multifunctionality and shows high electrocatalytic activity for quasi-solid-state dye-sensitized solar cells with a power conversion efficiency of 8.42 %, the hydrogen evolution reaction, the oxygen evolution reaction, and water splitting. The electric power output from tandem quasi-solid-state dye-sensitized solar cells under one-sun illumination is sufficient to split water and exhibits a solar-to-hydrogen conversion efficiency of 5.58 % with Fe0.37 Ni0.17 Co0.36 Se as the electrocatalyst in this integrated system. Owing to a remarkable synergistic effect, quaternary Fe0.37 Ni0.17 Co0.36 Se is proven to be superior to ternary nickel cobalt selenide in terms of conductivity, electrocatalytic activity, and photovoltaic performance.

Molecular Solids
Molecular crystalline solids, such as ice, sucrose (table sugar), and iodine, are solids that are composed of neutral molecules as their constituent units. These molecules are held together by weak intermolecular forces such as London dispersion forces, dipole-dipole interactions, or hydrogen bonds, which...
