Buried Interface Molecular Hybrid Enables Efficient Perovskite Solar Cells

<正>Perovskite solar cells（PSCs） with a positive-intrinsicnegative（p–i–n, commonly referred to as “inverted”）structure are becoming commercially attractive due to their superior power conversion efficiency（PCE） and better operational stability as compared to the “normal” structure device.[1–5] Nonetheless, further improvements in the device performance of inverted PSCs are hampered by interface losses, particularly where the buried interfaces are responsible for perovskite crystallization and chargecarrier extraction.[6–9]
