Article Synopsis
- In perovskite solar cells, stress and defects at the interfaces can lead to decreased performance and stability, especially in films made without antisolvent.
- The study introduces guanidine sulfate (Gua-S) at the interface of tin oxide and perovskite to improve film morphology, reduce stress significantly (from 50.6 to 20.72 MPa), and enhance crystallinity.
- The Gua-S treated solar cells achieved notable performance with an open circuit voltage of 1.08 V, 22.34% efficiency, and maintained over 87% of their initial efficiency after 2000 hours, showcasing its effectiveness in addressing critical challenges in solar cell performance.
