Room temperature buried molecular engineering boosts the photovoltaic performance of wide-bandgap and all-perovskite tandems

Key Points

The aim is to improve the efficiency of all-perovskite tandem solar cells using a buried interface modifier.
Utilized GBAM as a buried interface modifier at room temperature.
Performed co-annealing of GBAM with the perovskite layer.
Optimized the bottom interface of the wide-bandgap perovskite.
Achieved a photovoltaic performance of 29.07% for 2-terminal perovskite-perovskite tandem cells.

Abstract

GBAM is used as buried interface modifier at room temperature. Co-annealing GBAM with perovskite layer optimizes bottom interface of wide-bandgap perovskite, achieving 29.07% for 2-terminal perovskite–perovskite tandem cells.
