An investigation on the impact of temperature variation over the performance of tin-based perovskite solar cell: A numerical simulation approach

Hybrid inorganic-organic perovskite solar cells (PSCs) have grabbed the interest of the researchers worldwide because of their exceptional performance in past few years. The PSCs have exhibited tremendous improvement in performance within a decade with increment in Power conversion efficiency (PCE) from 3.2% to 25.2%. The widely used absorber layer in PSCs is methylammonium lead trihalide (MAPbX(3) where X = Cl, Br, I). The toxicity of Lead (Pb) is a matter of distress by some researchers, so Tin (Sn) is being used as a replacement. However, the Tin-based PSCs still lag behind in performance as compared to lead-based PSCs. In this work, we demonstrate an efficient design of Tin based PSCs with high efficiency of 23.35%. We also report the effect of temperature variation (300-400 K) on the performance of MASnI(3) based solar cell using three different ETLs. (C) 2019 Elsevier Ltd. All rights reserved.

Automated summary

Hybrid inorganic-organic perovskite solar cells (PSCs) have gained global interest for their exceptional performance in the past few years. While lead-based PSCs have shown significant improvement in power conversion efficiency, researchers are exploring tin-based alternatives due to concerns over the toxicity of lead. Despite tin-based PSCs still lagging behind in performance, this study demonstrates an efficient design with high efficiency.
