Abstract

CdTe based solar cells with high efciency alternative to solar cells from elemental semiconductors is an important work carried out over the decades. However, the research has not yet yielded the highest possible efciency with CdTe absorber. Selection of suitable window layer and optimizing the thickness of the diferent layers is still a quest in researchers. Numerical simulation of the diferent material combinations can speed up the research work. In this regard, numerical simulation is an essential tool to fnd the optimized structure for the enhanced device performance. In the present work, the thicknesses of window and absorber layers, one of the crucial factors that afect the solar cell performance, are tuned for ZnO/CdS/CdTe system. In case of CdS/CdTe solar cells, spectral loss created by CdS lowers the cell efciency. Concept of bilayer window is useful to minimize the loss at window layer. Hence the ZnO/CdS bilayer window is adopted and demonstrated that the cell efciency can be increased up to 17.66% with current density of 28.4 mA/cm2 and 73.7% fll factor.
