2-Terminal and 3-Terminal Subcell Characterization Platforms for Emerging Tandems

Significant improvements in performance has been reported for emerging tandem solar cells like the monolithic perovskite/Si tandem solar cell, the lack of simple electrical characterization methods impedes further development and successful commercialization of them. In this study, we report comprehensive electrical characterization methods based on either 2-terminal or 3-terminal platform that can accurately and easily analyze the subcells of monolithic emerging tandems. In addition to the current-voltage and external quantum efficiency measurements, advanced characterization methods for subcells such as impedance spectroscopy and thermal admittance spectroscopy will be demonstrated.
