Significant advancements have been made in improving the durability and stability of perovskite solar cells recently. Here are some key developments:
Recent Advancements
- Chemical Stabilization: Researchers have developed a method to stabilize tin-containing perovskites by adding diamine, which helps to achieve a better surficial tin-lead balance and creates stable barrier layers. This innovation aims to enhance both efficiency and longevity of perovskite solar cells.
- Surface Functionalization: A process involving 5-ammonium valeric acid iodide (5-AVAI) enables the uniform growth of aluminum oxide (Al₂O₃) barriers through atomic layer deposition. These barriers significantly suppress halide migration, a major cause of instability in perovskite solar cells.
- Encapsulation Techniques: Efforts are being made to improve the encapsulation of perovskite cells to increase their lifespan. While silicon offers longer durability, tandem cells combining perovskites with silicon are seen as a promising solution to balance efficiency and durability.
- Mechanical Durability and Flexibility: Flexible perovskite solar cells are gaining attention but still face challenges related to mechanical robustness. Addressing these issues is crucial for expanding their applications.
These innovations suggest that while durability challenges remain, significant progress is being made to enhance the stability and performance of perovskite solar cells.
