Simulation and Optimization of Cds/ZnSnN 2 Structure for Solar Cell Applications with SCAPS-1D Software
In this paper, we are interested in simulating and modeling of Cds/ZnSnN2 structure for a solar cell using SCAPS-1D. The ZnSnN2 is considered as one of the promising absorber materials for photovoltaic application due to the high optical efficiency and the low cost. In the present work, we have investigated the effects of the thickness of the buffer and the absorber layers, the temperature on electrical parameters (Voc) the open-circuit voltage and (Jsc) the short-circuit current density, (FF) fill factor and (η) efficiency of the solar cell. The results show a remarkable improved of the efficiency a η = 26.49% under the AM1.5G spectrum, one sun and deformation of 0.51% between the Cds and the ZnSnN2. The achieved results show that the ZnSnN2 is a very promising material for thin film photovoltaics and offers a number of interesting advantages compared to (CIGS) and (CZTS) due to its high efficiency, earth-abundant, non-toxic and inexpensive element.
