Optical Investigations of Cd Free Cu₂ZnSnS₄ Solar Cells

We conducted optical simulations with the goal of determining the optimal design of the Cu₂ZnSnS₄ (CZTS) solar cells with In₂S₃, ZnS and ZnSe as buffer layers. The model is parameterized with the complex index of refraction of each layer in the stack. Using optical modeling, the quantum efficiency (QE) of the solar cell is calculated and used to calculate the maximum short circuit current. A comparison of the solar cell performance in simulations using In₂S₃, ZnS, ZnSe and conventional CdS revealed an increase in QE while using ZnS, ZnSe and In₂S₃ as buffer layers.
