Ch/ChE 140 ab. Principles and Applications of Semiconductor Photoelectrochemistry. 9 units (3-0-6): second, third terms. The properties and photoelectrochemistry of semiconductors and semiconductor/liquid junction solar cells will be discussed. Topics include optical and electronic properties of semiconductors; electronic properties of semiconductor junctions with metals, liquids, and other semiconductors, in the dark and under illumination, with emphasis on semiconductor/liquid junctions in aqueous and nonaqueous media. Problems currently facing semiconductor/liquid junctions and practical applications of these systems will be highlighted. Part b not offered 2017-18. Instructor: Lewerenz (a).
