Numerical modeling of CdS/CdTe solar cells: a parameter study

CdTe-based solar cells are candidates for inexpensive and relatively efficient solar cells. Efficiencies of as high as 13.4% have been reported for these cells. In order to evaluate their potential numerical modeling is performed to analyze the factors that limit cell performance. The purpose is to model the effects of the pertinent material parameters on predicted cell performance so that a better understanding of the material characteristics can be achieved. Numerical modelling is performed to determine a set of material parameters consistent with measured cell performance. These parameters can then be used to make realistic performance projections
