Perimeter recombination on multi-junction solar cells has been studied mainly through individual single-junction solar cells in the past. In this study, we provide a luminescence method to investigate the perimeter recombination within an intact tandem solar cell, which helps us better understand the perimeter effect on each sublayer.
