- Abstract
Multijunction solar cells are currently leading in efficiency among all types of solar cells. However, the efficiency of those cells under concentrated illumination is limited by the trade‐off between shadowing by the contact grid and series resistances. In this paper, we provide a method using luminescence to image the current transport efficiency for a precise and rapid measurement of the resistance effect. Light beam induced current (LBIC) measurement is used for the first time to calculate current transport efficiency in comparison with that of the luminescence method. Profiles of transport efficiency in both means are in good agreement. Furthermore, a quasi‐3‐D simulation using SPICE is used to explain the transport efficiency image. We find that the carrier transport efficiency distribution is primarily influenced by the perimeter recombination of the middle cell.
