Record-Breaking Performance
In a groundbreaking achievement, scientists at the Chinese Academy of Sciences have created a flexible solar cell that has set a new efficiency benchmark. This device reached a power conversion efficiency (PCE) of 24.6% — the highest ever recorded for a flexible solar panel.
How It Works: Antisolvent Seeding Innovation
The key to this efficiency lies in a technique known as antisolvent seeding. This method helps form a smoother and more efficient connection between the perovskite and CIGS (copper indium gallium selenide) layers. The improved interface allows better charge transfer, reduces energy loss, and enhances overall performance. Remarkably, the cells maintained 93% of their output even after 3,000 bends.
Why Flexibility Matters
Unlike conventional rigid panels, these bendable solar cells open up a wide array of applications. Their lightweight and durable nature make them ideal for wearable electronics, rollable chargers, drones, and even space-based solar arrays. They offer a promising alternative for areas where rigid panels aren’t practical.
A New Era for Solar Technology
This milestone suggests that flexible solar cells could not only compete with but possibly outperform traditional panels in the near future. As research continues, we may soon witness a shift toward more versatile, efficient, and adaptable solar power solutions.
