Semiconductor photoelectrochemistry

Abstract

This article discusses methods and experimental protocols in semiconductor electrochemistry. We first introduce the basic principles that govern the energetics and kinetics of charge flow at a semiconductor–liquid contact. The principal electrochemical techniques of photocurrent and photovoltage measurements used to obtain important interfacial energetic and kinetic quantities of such contacts are then described in detail. After this basic description of concepts and methods in semiconductor electrochemistry, we describe methods for characterizing the optical, electrical, and chemical properties of semiconductors through use of the electrochemical properties of semiconductor–liquid interfaces.
