Investigating the Effects of Bending on the Properties of Flexible Perovskite Films

Öffentlich Deposited

Perovskite solar cells, acclaimed for efficient light absorption of the novel perovskite material, face challenges in stability. This study examines the impact of bending on flexible perovskite films. AFM scans were taken to ensure proper sample fabrication. By employing time-resolved photoluminescence to probe carrier lifetimes and XRD to calculate lattice strain, comparative analysis was done before and after bending the flexible samples for 10 minutes at an 8 mm radius. We found significant reduction (>26%) in carrier lifetimes of three samples due to strain, indicating an increase in defect density, and an increase in bandgap of 1-2% (from UV-Vis), stressing the need for strain management in designing perovskite devices, crucial for their long-term performance in flexible electronics.
