Hello, I found on the Internet that the value of FF for commercial solar cells is about 0.6 to 0.7. Is it a regular figure or has this value changed in today's technology?
Thank you for your reply.
Dear Boris,
The Fill Factor (FF) is essentially a measure of quality of the solar cell. It is calculated by comparing the maximum power to the theoretical power that would be output at both the open circuit voltage and short circuit current together. Last solar cells technologies (second and third generation) were known by their high FF and high conversion efficiency (e.g. CIGS, CdTe, ....)
as an exemple FF of 80.6% and an efficiency of 22.6% (take a look in attached file).

Good luck.
dear sir
From my experience, typical fill factors range from 50% to 82%.
