Self-Regulated Bilateral Anchoring Enables Efficient Charge Transport Pathways for High-Performance Rigid and Flexible Perovskite Solar Cells
Highlights Robust interface molecular bridge was constructed by employing self-transforming squaric acid (SA) to reduce residual stress and passivate defects at the buried interface. Attributing to the efficient charge transport pathways, the SA-modified perovskite solar cells demonstrate high photo...

| description | Highlights Robust interface molecular bridge was constructed by employing self-transforming squaric acid (SA) to reduce residual stress and passivate defects at the buried interface. Attributing to the efficient charge transport pathways, the SA-modified perovskite solar cells demonstrate high photovoltaic performance with power conversion efficiency up to 25.50% (rigid) and 24.92% (flexible). The SA-modified devices demonstrate excellent stability under various environmental stress conditions, including humidity, thermal aging, light irradiation, and bending. |
