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
