ABX₃ structured perovskite materials plays a vital role in current photovoltaic since it started in 2009 (~3.1%).  The high Power Conversion Efficiency (PCE) as well as flexible and cost effective processing techniques turned it do more optimizations on it.  Methylammonium Lead Iodide (CH₃NH₃PbI₃) absorbing material is the mostly optimized composition which gives better PCE (~25%).  Though, structural instability and toxic nature of lead to human body were made to find the alternate for Lead (Pb).   Bismuth is a nontoxic and stable metal which has similar optoelectronic properties as lead. Here, Bismuth halide perovskite absorbing material was synthesized by simple chemical method.  The XRD analysis confirms that the mixed halide was formed.  From the UV-Visible absorption spectrum, this bismuth perovskites have more absorption in UV region and the bandgap (E_g) is 2. eV.  Field Emission Scanning Electron Microscope is clearly showed the film is smoothly coated with high surface coverage.  CH₃NH₃PbI₃ based perovskite solar cells were fabricated by using spray pyrolysis method, spin coating technique.  Finally the power conversion efficiency of the fabricated solar cells were analysed by Keithely Sourcemeter 2400.
