Researchers from Huaqiao University in China have created perovskite solar cells with a record efficiency of 26.39%. The breakthrough comes from using an ultra-thin polymeric interlayer (D18) that blocks ion diffusion, improving stability and performance.

 

These cells address key issues like ion migration, which causes instability and reduced lifespan in perovskite solar cells. The D18 interlayer also enhances energy alignment and efficient hole extraction.

 

With 95.4% efficiency retention after 1,100 hours of operation, this innovation marks a significant leap in stable, high-performance solar technology.
