Hybrid organic–inorganic halides are considered as outstanding materials when used as the absorber layer in perovskite solar cells (PSCs) because of its efficiency, relieve of fabrication and low‐cost materials. However, the content of lead (Pb) in the material may origin a dramatic after effect on human's health caused by its toxicity. Here, we investigate replacing the lead in MAPbI3 with tin (Sn)...
Mixed bromide-iodide methylammonium lead-halide perovskites have been synthetized from methylamine, lead nitrate and the corresponding hydroX acid (X= I, Br) precursors and thereafter deposited as thin films onto FTO substrates by spin coating or dipping. Thin film perovskites were then characterized by X-Ray Diffraction, optical spectrometry and photoluminescence. All synthetized MAPbI3, MAPbBr3...
