By an analysis of the photodetection process, the response of photodetectors to wide band, noncoherent light and guidelines for its improvement are determined. In this paper, the phenomenon of multiple reflections within the emitter of a reflecting-translucent and a reflecting-opaque photocathode is analyzed. Geometrical and optical configurations and solid state parameters are evaluated in terms of their effect on the photodetection process. The quantum yield, the percent of incident light absorbed, and the collection efficiency are determined as functions of the thickness of the emitting layer. These results are then employed to suggest areas of improvement in the use of state-of-the-art photocathodes.
