Yes you can use SCAPS- 1D to simulate perovskite solar cell structure.
But you have to consider the function of each layer.
It is so that the perovskite will act as light absorber it needs to a hole transport layer and an electron transport layer. Then two metal layers acting as solar cell electrodes.
As an example of using ECAPS-1D please follow the papers:

Thanks for your answer.. But actually I am using metal oxide/metal/metal oxide structure in place of ITO. I found the input parameters for Tio2 for SCAPS-1D but couldn't find input parameters of SCAPS-1D for Ag metal as I am using Ag metal as layer not as electrode so from where I can found it?
