Illumination Level Effects on Macroscopic Parameters of a Bifacial Solar Cell

This study presents a method based on the experimental measurement of the short-circuit current ( I sub(cc) ) and the open circuit voltage ( V sub(co) ) of the solar cell. It permits the determination of recombination parameters such as: diffusion length ( L ), back surface recombination velocity ( Sb ), intrinsic junction recombination velocity ( S sub(jo) ), and macroscopic parameters in particular, the shunt and series resistances of a bifacial solar cell for various illumination levels (n). Illumination level effects on macroscopic parameters are highlighted.
