• Resumen

  • A physical chemistry experiment illustrating photochemistry, cyclic voltammetry, the properties of semiconductors, and surface chemistry is described. The experiment consists of constructing a liquid-junction photochemical cell, determining the cell parameters, then modifying the surface of the electrode to enhance the conversion efficiency of the cell. The students will learn some fundamental physical and chemical principles related to light and electricity interconversion as well as the properties of semiconductors. The experiment can also be developed into an undergraduate research or independent study project.
