Close-Space Sublimation-Deposited Ultra-Thin CdSeTe/CdTe Solar Cells for Enhanced Short-Circuit Current Density and Photoluminescence

Abstract:
The responsive quantum efficiency of semitransparent cesium telluride photocathodes has been found to be significantly increased by the application of high electric fields (a few MV m(-1)) such as are encountered in proximity-focused image converters. Measurements of the magnitude of the effect are presented as functions of applied field and of wavelength over the 120-800 nm range. An interesting anomaly was found in the pair-production region in the vacuum uv; otherwise, the results are fairly consistent with the effects of a simple Schottky lowering of the surface potential barrier of the photoemitter.
