Abstract

Abstract: Lead-free 2D perovskite [NH3 -(CH2 )2 -NH3 ]MnCl4, was introduced in ZnO: Al/TiO2 /[NH3 -(CH2 )2 -NH3 ]MnCl4 /CuI/Au structure for solar cell application using SCAPS 1D. The optical band gap (1.8 eV) was determined from UV-transmittance spectrum and the result is used in the simulation. The effects of the absorber layer thickness and the temperature on the solar cell characteristics were investigated. Optimum absorber-thickness was 700 nm with a Jsc = 17.999 A cm −2, Voc = 1.4659 V, FF = 67.84% and PCE of about 17.90%. To our knowledge no photovoltaic simulation has been reported for this material, however its efficiency is promising for a new ecological absorber of solar cells.
