摘要：
Screen printed CdTe layer was employed as a source for close spaced sublimation process. By controlling the initial mixture of screen printed sourer, the Cd content in the CdTe film varied from 49.5% to 48%. The solar efficiency of CBD CdS/CdTe cell strongly depended on the stoichiometry of CdTe films due the bulk resistivity change ranging from 2x10(6) to 3 x 10(4) Omega cm. By comparing with the dark forward current of screen printed CdS/CdTe cell, it is suggested that in the CBD CdS/CdTe cell the grain size of CBD CdS layer should he increased to reduce the interface leakage current at low forward bias.
