Tryptamine Terminated Low‐Dimensional Interfaces Enabled High Performance Perovskite/Silicon Tandem Solar Cells

Key Points

• The aim is to investigate the impact of tryptamine terminated low-dimensional interfaces on the performance of perovskite/silicon tandem solar cells.
• Utilized tryptamine to modify the interfaces in tandem solar cells.
• Evaluated electrical performance and stability under operational conditions.
• Achieved an open-circuit voltage of 1.987 V.
• Demonstrated enhanced operation stability due to suppressed halide phase segregation.
