Abstract
AbstractIn this work, the impact of different Cu(In1‐xGax)(Se1‐ySy)2 solar cell structures on the shift of the dominant recombination region at varying light intensities was investigated. A new parameter was proposed to account for the dominant recombination region relative to the minimum band gap location in a graded absorber. Additionally, the influence of shunt resistances on the dominant recombination location for different CIGSSe solar cell structures was modeled. Within the investigated illumination range, correlations between the dominant recombination location and solar cell parameters as well as their temperature dependence were discussed.
