A multi-dimensional interface helps perovskite solar cells maintain stability for over one year
In short: Researchers have developed a way to make perovskite solar cells much more durable by engineering a 2D/3D interface. By creating a gradually-organized junction between two different perovskite structures, the team produced solar modules that maintained their efficiency for over 10,000 hours under controlled conditions.
While perovskite solar cells can reach high efficiencies, they often fail to meet the long-term stability required for the market. This study used a printable industrial-scale process to create 10 x 10 cm2 modules with a specific 2D/3D junction, achieving efficiencies up to 14.6% in standard cells.
The researchers demonstrated that these modules could operate for more than 10,000 hours with zero loss in performance. However, these results were measured under controlled standard conditions, which may not fully reflect performance in unpredictable outdoor environments.
Why it matters: This structural engineering approach provides a pathway toward the commercialization of stable, low-cost perovskite solar technology.
