Design and Optimization of Efficient $\mathrm{FeS}_{2}$ Solar Cell

Abstract

Nowadays, one of the key priorities in photovoltaic solar cell technology is reducing fabrication cost, at that time maintaining high conversion efficiency. The FeS2 (pyrite) is an ecologically viable semiconductor material which has very suitable optoelectronics properties for the economically benign solar cell. So, nowadays researcher shows interest in FeS2based solar cell. In this research work, numerical analysis of FeS2solar cell is done with CdS as a potential buffer layer. FTO is used as a TCO layer to get better performance. In the study, the proposed ultra-thin cell structure was found with a conversion efficiency of 17.28% with $\pmb{V_{oc}=0.56}$ V, $\pmb{J_{sc}=37.99}\ \mathbf{mA/}\mathbf{cm}^{2},\pmb{FF=81.89\%}$. The thermal stability of the cell is also investigated.
