The ratio g/I(0) defines the photocurrent efficiency . In the absence of surface recombination, qg corresponds to the photocurrent density Jphow measured in the external circuit. The Gartner equation has been used successfully to explain the photocurrent-potential characteristics of many semiconductor electrodes under conditions where surface recombination is absent. Plots of ln — O) against dsc (which according to the Mott-Schottky relationship is proportional to (1/ — have... 

Analytic models of photoelectrochemical devices closely resemble models of solid-state solar cells (see, e.g., Refs. 133-145). Several analytic current-voltage relationships have been derived which use the general approach described above and differ in their treatment of surface reactions and recombination within the depletion and neutral layers. The model of Gartner,146 developed for a p-n junction device, is commonly used in the analysis of photoelectrochemical devices.147 149 Recombination and thermal generation... 

How important can this relationship enhancement be Gartner further suggests that by 2005, enterprises will move strongly to SRM methodologies or they will see profit reductions of close to two percent (Gartner, 2001, p. 2). This firm lists some of the potential benefits of SRM in Figure 9.1.
