Laser beam induced current (LBIC) mapping of InGaP/GaAs/Ge triple junction solar cells with luminescence coupling

In this study, we introduced the laser beam induced current (LBIC) mapping method of InGaP/GaAs/Ge triple junction solar cells considering the luminescence coupling effect. Results have shown qualitative agreement between the acquired simulation and measurement data. Moreover, the current generated in the limiting subcell has been observed to be a mixture of luminescence coupling and measurement artifacts in excess of its dark current. Using the LBIC mapping method can provide spatial luminescence coupling current distribution in the subcell, which can serve as a guide on how to design multijunction solar cell that optimizes this effect.
