Boosting the efficiency of single junction kesterite solar cell using Ag mixed Cu₂ZnSnS₄ active layer.

ABSTRACT: We propose a silver (Ag) mixed Cu₂ZnSnS₄ (ACZTS) based solar cell architecture to improve the efficiency of single junction Cu₂ZnSnS₄ (CZTS) solar cells. The configuration exploits enhancement of depletion region using a CdS/ACZTS/CZTS architecture. The doping concentration of different layers is adapted such that the primary absorber layer (ACZTS) may become fully depleted and CZTS acts as back surface field layer. We analyze the prospect and performance of the proposed architecture through rigorous optoelectronic simulations. We also study the role of the Schottky barrier at the back-contact interface of a conventional CZTS cell. In this regard, we propose to use an Ohmic contact to increase the open circuit voltage by replacing the molybdenum
