Abstract
This study explores the application and utility of BaZrS3-based perovskite solar cells (PSCs) for thin-film photovoltaic applications. The proposed device exhibited stable current up to 1.1 eV and maintained over 65% quantum efficiency across a broad spectrum. The Mott-Schottky analysis indicated a bandgap of approximately 1.7 eV. Nyquist and Bode plots confirmed robust impedance behaviour. The device displayed <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\mathbf{V}_{\text{oc}}=1.33\ \mathrm{V}, \mathbf{J}_{\mathbf{sc}}$</tex> = 16.56 mA/cm2, FF = 83.97%, and Efficiency = 18.58%. BaZrS3's exceptional optical and electrical properties, coupled with environmental stability, position it as a promising material for advanced PSCs.
