Abstract

Replacing lead atoms in halide perovskite materials is of significant importance for the development of environmentally friendly perovskite solar cells. In this paper, we investigated the effect of doping the MAPbI<subscript>2.6</subscript>Cl<subscript>0.4</subscript> hybrid perovskite (MA—methyl ammonium) with non-toxic elements, such as alkaline earth metal ions (Mg<superscript>2+</superscript>) and transition metal ions (Zn<superscript>2+</superscript>). The structural, morphological, and optical properties of the prepared samples were analyzed using X-ray diffraction (XRD), scanning electron microscopy (SEM), atomic force microscopy (AFM), and UV–Vis. spectroscopy. Finally, the doped films were used as photoactive layers in solar devices in order to evaluate their photovoltaic performance. Zn proved to be more appropriate to replace partially Pb and films with higher quality were obtained. As a result, the MAPb1<subscript>−x</subscript>Zn<subscript>x</subscript>I<subscript>2.6</subscript>Cl<subscript>0.4</subscript> based solar cells have demonstrated a slight improvement of the photovoltaic performances, resulting in a uniform and narrower PCEs (power conversion efficiency) range, compared to pristine MAPbI<subscript>2.6</subscript>Cl<subscript>0.4</subscript> based devices.
