Performance Analysis of Solid-state Dye Sensitized Solar Cell with Sb₂S₃ as Novel Hole Transport Material

Solid-state dye-sensitized solar cell (ss-DSSC) has drawn the recent contemplation of photovoltaic (PV) fraternity as a viable substitute for fluid electrolyte for improving power generation efficiency, durability and minimizing instability in dye-sensitive solar cells. Nevertheless, ss-DSSC suffers from poor performance, which can be improved by including a hole transport layer. This work presents device modelling of a Al/FTO/TiO<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf>/Z907/Sb<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf>S<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</inf>/Ni ss-DSSC with antimony trisulphide (Sb<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf>S<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</inf>) as a novel hole conductor. The PV characteristics of the ss-DSSC covering the influence of charge transport layer (Electron and hole transport layers) thicknesses, doping concentration together with defect density of hole transport material (HTM), and ambient temperature are evaluated by means of the SCAPS-1D software package. The estimated results provide PV performance parameters with voltage in open circuit (VOC) of 1.28 V, current density in short circuit (JSC) of 15.97 mA/cm<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup>, fill factor (FF) of 84.15% and efficiency of 17.23% in proposed structure, highlighting the potential of Sb<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf>S<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</inf>as HTM. Consequently, these results might offer a valuable perspective for creating innovative, affordable, and extremely effective ss-DSSCs.
