The highest power conversion efficiency (PCE) for organic-inorganic perovskite solar cells based on lead is reported as 25.2% in 2019. Lead-based hybrid perovskite materials are used in several photovoltaics applications, but these are not highly favored due to the toxicity of lead and volatility of organic cations. On the other hand, hybrid lead-free double perovskite has no such harm. In this research study, SCAPS numerical simulation is utilized to evaluate and compare the results of perovskite solar cell based on double perovskite FA 2 BiCuI 6 and standard perovskite CH 3 NH 3 PbI 3 as an active layer. The results show that the power conversion efficiency obtained in the case of FA 2 BiCuI 6 is 24.98%, while in the case of CH 3 NH 3 PbI 3 , it is reported as 26.42%. This indicates that the hybrid organic-inorganic double perovskite FA 2 BiCuI 6 has the ability to replace hybrid organic-inorganic perovskite CH 3 NH 3 PbI 3 to expand next-generation lead-free harmless materials for solar cell applications.

<p>The effect of Methylammonium Iodide (CH<sub>3</sub>NH<sub>3</sub>PbI<sub>3</sub>) perovskites (MIP) concentration on the performance of perovskites sensitized solar cell (PSC) was studied. Three MIP concentrations, namely 0.2, 0.4, and 1.0 M were prepared. In this study PSC with a sandwich structure of ITO/TiO<sub>2</sub>/ MIP /electrolyte/ Pt film was fabricated for this purpose. It was found that power conversion efficiency (PCE) increased with the increasing the concentration of MIP, from 0.01 to 0.21 % as the concentration increase from 0.2 to 1.0 M. Photoluminescence (PL) study showed that the increase of the MIP concentration decrease therecombination of carrier in the device. Electrochemical impedance spectroscopy (EIS) analysis also shows that with the increased of MIP concentration results in the decreased of the R<sub>ct </sub>due to the improvement of the carrier transport in the devices. </p>
