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.

Our Secondary School editors work hard to distill all the JCE materials to produce a fraction of particular interest to high school teachers. We call it CLIC.
In recent years we have worked hard to better match our advertisers with our readers. When shopping for chemistry education materials, visit our advertisers' WWW sites first.
