Pb-Free Metal Halide Double Perovskite, Cs2 InAgCl6, in the Solar Cells Application

Perovskite-based solar cells include Pb, which is both poisonous and unstable, and resolving this problem will involve discovering other materials that do not contain lead. This study synthesizes a novel series of inorganic lead-free perovskite solar cell sensors using Cs 2 InAgCl 6 as the main visible light absorption component. Studies have been done on the structural and optical characteristics of these materials and their performance has been verified in the photovoltaic (PV) device. These materials were successfully prepared and deposited as thin films to prepare perovskite solar cells. Structural examinations of the prepared materials were performed by XRD analysis, and the optical properties were studied using UV-Vis spectroscopy of the prepared materials. The performance of the PV device shows the energy conversion efficiency (PCE [Formula: see text]%) in the light intensity (100[Formula: see text]W/m 2 ).
