Key Points

The aim is to improve the performance and stability of perovskite solar cells by using ALD-Al2O3 as a buffer layer.
Employ atomic layer deposition (ALD) to apply Al2O3 as an electron transport layer buffer.
Analyze the interfacial properties and defects in perovskite solar cells with and without the buffer.
Test the efficiency and stability of the solar cells under operational conditions.
ALD-Al2O3 significantly reduced interfacial defects in perovskite solar cells.
Solar cells with the buffer layer showed enhanced efficiency gains compared to those without.
The stability of the solar cells improved when ALD-Al2O3 was incorporated as the buffer.

Implication

Research demonstrates improved efficiency and stability of perovskite solar cells using ALD-Al2O3 as a buffer layer.

Abstract

Perovskite solar cells (PSCs) have achieved remarkable efficiency gains in recent years, yet their practical performance is still limited by interfacial defects and stability issues. Here, we employ atomic layer...
