Impact of Glancing Angle Deposition Technique on the Performance of SnS Thin Film Solar Cell: SCAPS-1D simulation

Abstract

Thin film materials are outstanding in the field of solar cells because of their low cost and good performance. One such material is SnS, which has higher absorption coefficient and earth richness. However, to date, the efficiency of thin-film solar cells has not been up to date, which limits their potential use in the PV market. In this paper, we design and simulate an efficient SnS based solar cell using glancing angle deposition (GLAD) technique, by which the deposition angle of SnS can be altered. In this regard, CZTSSe based SnS solar cell which has 7.83% efficiency reported in our previous paper is used in this work to further increase the efficiency of SnS solar cells. The performance of SnS solar cell for 0° ,45°, 55°, 65°, 75°, 85° deposition angles of SnS is calculated using the SCAPS-1D simulator. The optimized results are obtained at 85° deposition angle of SnS. At this angle the V <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">OC</inf> and J <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">SC</inf> obtained are 0.66 V and 27.98 mA/cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> respectively. Also, the efficiency achieved by this solar cell is 12.17%. The results obtained in this paper will open a path for the fabrication and development of SnS based solar cells.
