Investigating the Impact of Temperature on the Photovoltaic Properties of CsSnI₃-Based Perovskite Solar Cells

Cesium tin iodide (CsSnI <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</inf> ) demonstrates favorable attributes as a viable and cost-effective absorber material within the domain of lead-free perovskite solar cells (PSCs). The high light absorption capabilities of CsSnI <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</inf> render it highly efficient in converting solar energy into usable power. The high prevalence of cesium and tin contributes to their affordability. The persistence of lead toxicity and long-term stability concerns remains a challenge, however, ongoing research endeavors aim to address these challenges, hence enhancing the appeal of CsSnl <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</inf> PSCs as a viable contender in the field of solar energy. The main aim of this research is to investigate the impact of the temperature on the photovoltaic (PV) properties. The present study employed the 1D-SCAPS software to conduct the investigation. PSCs have emerged as a promising technology for the generation of sustainable energy, primarily due to their improved efficiency and cost-effectiveness in the production process. An investigation of how temperature changes affect the device's efficacy has been conducted. The ITO/PCBM/CsSnCl <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</inf> /Cul/Au device structure has been presented. The temperature fluctuates between 300 and 400 k, split into 10 equal intervals for this proposed investigation. The CsSnI <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</inf> material's band gap is determined to be 1.3 eV. The PV measurements that follow show the following values when the temperature is changed: PCE = 23.3%, the V <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">OC</inf> = 0.87 V, the J <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">SC</inf> = 30.76 mA/cm 2 , and the FF = 86.69%.
