Polyacrylonitrile-Boosted Surface Coverage of 2D WSe 2 at the SnO 2 /Perovskite Interlayer for High-Performance Perovskite Solar Cells

Key Points

• To evaluate the impact of polyacrylonitrile on the surface coverage of 2D WSe2 and its effects on perovskite solar cells.
• Utilized polyacrylonitrile to enhance surface coverage of 2D WSe2 at the SnO2/perovskite interlayer.
• Assessed the efficiency and stability of the perovskite solar cells after intervention.
• Perovskite solar cells retained 95% of their initial efficiency after exposure to testing conditions, indicating strong stability.
