2D Ruddlesden-Popper (RP) metal-halide perovskite solar cells (PSCs) have attracted growing attention for their fascinating optoelectronic properties and enhanced stability as compared to 3D counterparts. Here, we report the fabrication and characterization of acetamidinium substituted 2D RP (PEA)2(MA(1-x)AAx)n-lPbnI3n+l(PEA: phenylethylammonium, MA: methylammonium, AA: acetamidinium, x = 0 and 0.1, and n = 2) perovskites. We have investigated the effect of antisolvent, chlorobenzene (CB) on the structural, optical, and photovoltaic properties of 2D PSCs. Perovskite films displayed the uniform polycrystalline nature with high coverage and blended texture after the application of antisolvent. The structural and optical investigations suggest that n = 2 ((PEA)2MAPb2I7 and (PEA)2(MA0.9AA0.1)Pb2I7) films manifest the triclinic crystal structure with tunable optical bandgap ranges from 2.08 to 2.13 eV. The champion PSC based on (PEA)2(MA0.9AA0.1)Pb2I7) with CB addition exhibits a power conversion efficiency of ≈ 0.66% and a short-circuit current density (J-{sc}) of 3.80 mA/cm2. The open-circuit voltage (V-{oc}) and fill-factor (FF) for this device are 0.56 V and 30%, respectively. This work is currently in progress to achieve better performing photovoltaic devices.
