Recently, perovskite materials opened up a door for the researchers due to their flexibility, photonic conversion efficiency and cost effectiveness. In this work, we study the performances of various active materials categorized as organic, inorganic and organic-inorganic hybrid materials and compare their optical performances to select the efficient material with the help of finite difference time domain analysis (FDTD) and Device solutions provided in Lumerical simulator. We choose conventional active materials like poly(3-hexylthiophene) and [6,6]-phenyl-C61-butyric acid methyl ester (P3HT:PC61BM) as organic active material, cesium lead iodide (CsPbI3) as inorganic active material, and both formamidinium lead iodide (FAPbI3) and methylammonium lead iodide (CH3NH3PbI3 or MAPbI3) as organic-inorganic hybrid active material. Finally, we propose a simple modified thin film perovskite solar cell structure considering previously selected most efficient active material and we achieve maximum photonic conversion efficiency 17.4% having short circuit current density 26.1 mA/cm2 and open circuit voltage 0.78 V with a fill factor of 86%. © 2021 Elsevier GmbH
