Synergistic Defect Suppression and Stress Relief for Efficient Spray-Coated SnO2-Based Perovskite Solar Cells
{{output}}
The scalable fabrication of high-performance SnO2 electron transport layers (ETLs) via solution processing is hindered by colloidal aggregation and defect proliferation, which degrade perovskite solar cell (PSC) efficiency and stability. Here, we developed an ... ...
