Reviewing some research, I have found that most of the high-fill factor solar cells (FF > 60%) usually present very low series resistance (Rs) concerning the shunt (Rsh) ones. In this context, I would like to know what are the typical absolute values for these parameters in popular and high-efficiency solar cells like those based on Silicon, CIGS, Organic, Dyes, Perovskite, etc. Any reference or comment is welcome.
