The cell is simulated with the initial physical parameters and the following output is found. and in the second interface the VBO2 -0.38eV and the CBO2 is 0.22eV. Although there are less significance of CBO1 and VBO2 but VBO1 and CBO2 have a great impact on electron and hole collection at ETM and HTM of perovskite solar cell. It was found in a study that, the optimal value of CBO should be less than 0.3eV while the optimal value of VBO is less than 0.2eV . The quantum efficiency of the cell is initially lower but it is increasing with the increment of wavelength.
