Cr–O–In Interlocking for Window Layer Delamination Resistance in Operationally Stable Perovskite/Silicon Tandem Solar Cells

Key Points

The main aim is to enhance the operational stability of perovskite/silicon tandem solar cells through interface improvements.
Examined the interlocking mechanism of Cr–O–In in window layers
Evaluated the stability of fullerene/ALD SnO X interfaces
Tested delamination resistance under operational conditions
Cr–O–In interlocking significantly improves delamination resistance
Enhanced stability observed in tandem solar cells during operational testing

Abstract

Perovskite/silicon tandem solar cells have achieved remarkable efficiencies but remain limited by poor operational stability, primarily due to the instability of fullerene/atomic-layer-deposited (ALD) SnO X interfaces in the top window layer–an...
