1) Precise sorting of bifacial solar cells is important to minimize current mismatches and improve module performance. 2) Simulations were conducted to analyze different sorting approaches using characterization data from 35 bifacial solar cells. 3) Sorting cells by efficiency measured under 1000 W/m2 front-side illumination provided the highest maximum module power compared to sorting by short-circuit current, maximum power point, or efficiency at other illumination levels.
