A surface-reconstruction strategy that converts the excess unstable PbI₂ into a gradient lead sulfate-silica bi-layer on the surface of perovskite films by employing the rationally selected mediator ((C₂H₅O)₃Si(CH₂)₃NH₃)₂SO₄ in toluene, has been used to stabilize the soft perovskite lattice for synchronously boosting the power conversion efficiency and environmental stability of perovskite solar cells.

通过表面重建管理杂化钙钛矿中的二次相碘化铅以获得具有强大环境稳定性的高性能钙钛矿太阳能电池

一种表面重建策略，通过使用合理选择的介体 ((C ₂ H ₅ O) ₃ Si(CH ₂ ) ₃ NH ，将过量不稳定的 PbI ₂转化为钙钛矿薄膜表面的梯度硫酸铅-二氧化硅双层₃ )甲苯中的₂ SO ₄已被用于稳定软钙钛矿晶格，同步提高钙钛矿太阳能电池的功率转换效率和环境稳定性。
