Perovskite solar panels currently have a generally shorter lifespan compared to traditional silicon-based panels, though significant progress is being made to extend their durability.
- Traditional silicon-based solar panels typically last 25 to 30 years under real-world conditions, maintaining stable performance over this period.
- Early perovskite solar cells had relatively short lifespans, but recent advances have led to the development of perovskite solar cells with lifetimes approaching or exceeding 30 years in laboratory conditions, which could make them competitive with silicon panels in terms of longevity.
- Despite this progress, durability remains a key challenge for perovskite solar technology. Many current perovskite panels still fall short of silicon’s durability when exposed to prolonged environmental stress, such as moisture and ultraviolet light.
- Researchers are actively addressing these issues through improved encapsulation and protective coatings that have been shown to significantly increase stability, in some cases tripling the lifespan of perovskite cells.
- The near-term commercial strategy often involves tandem solar cells combining perovskite and silicon layers, leveraging the high efficiency of perovskites with the proven durability of silicon, thus achieving both improved efficiency and acceptable lifespan.
In summary, while traditional silicon solar panels remain more durable and reliable for 25–30 years, emerging perovskite solar cells are closing the gap, with some designs now expected to last similarly long under ideal conditions. Ongoing research to overcome durability challenges is key to perovskite panels becoming a viable long-term alternative or complement to silicon technology.
