First you need to specify very accurately the spectral power density of the illuminating light. Then you need to specify very accurately the absorption of, and transmission throught, light incident on the top cell. Then you must do the same for the bottom cell.

I think the attached file is very helpful.

Moreover, I agree with Atul Kumar that the SCAPS lectures can be also very helpful to you
