Abstract

Multi-junction solar cells are currently the efficiency leaders among all types of solar cells. However, efficiencies of multi-junction solar cells are limited by various series resistance when they are illuminated under high concentrations. In this paper, we provide a robust method to obtain the current transport efficiency mapping for a precise and rapid measurement of resistance effect using luminescence characterization. We verified the method on a triple-junction solar cell with illuminations on all subcells. The results successfully matched with both electrical measurement and simulation results. Light beam induced current (LBIC) measurement is used for the first time to compare with the luminescence mapping. Both methods show a similar profile of transport efficiency.
