Modeling of the efficiency of multijunction tandem of solar cells on the basis of cadmium telluride

Present article is devoted to modeling of the efficiency of multijunction tandem of solar cells on the basis of cadmium telluride. On the basis of numerical simulation of single-junction solar cells with use of AMPS-ID program the optimal structure of tandem multijunction CdS/Cd Te of solar cell has been elaborated. It has been shown that its highest efficiency in 31.8% could be reached at 50 nm of the thickness of CdS p-layer and 200 nm of CdS n-layer keeping fixed thickness of CdS Te n-layer equal 3000 nm and Cd Te p-layer equal 1000 nm.
