Dear Romana Yousuf,

PLease take a look at this link you are all information about your question.

Best regards

Thank you for your kind response

Current is dependent on the bandgap and illumination intensity. for current , colatge , ff and eff dependence on bandgap u can visit Conference Paper Design Issues for Optimum Solar Cell Configuration

I have prepared a demo tutorial for calculating SQ limit values, pls see https://youtu.be/KOd7Sz3ZAfk

@Atul Kumar, thank you for your valuable suggestions.

The Jsc depends on material bandgap and illumination. The ideal conditions of SQ where the main parameter to be considered is the bandgap, would provide you with the maximum Jsc expected, in my experience for 57.8 mA/cm2, the bandgap should be lower than 1 eV.
