A novel triple-alkali interlayer (LiOH/KCl/CsI) enhances perovskite solar cell (PSC) performance by controlling cation distribution. This method improves efficiency and stability, offering a promising pathway for advanced photovoltaic devices.

Area of Science:

  • Materials Science
  • Renewable Energy
  • Photovoltaics

Background:

  • Precise cation distribution is crucial for high-performance perovskite solar cells (PSCs).
  • Current methods like bulk doping and surface passivation have limitations in achieving homogeneity and avoiding defects.
  • Controlling cation dynamics is key to overcoming efficiency and stability challenges in PSCs.

Purpose of the Study:

  • To develop a new strategy for precise cation control in perovskite solar cells.
  • To investigate the effect of a triple-alkali interlayer on perovskite film crystallization and properties.
  • To enhance the power conversion efficiency (PCE) and operational stability of perovskite solar cells.

Main Methods:

  • A triple-alkali interlayer (LiOH/KCl/CsI) was deposited on the electron transport layer before perovskite crystallization.

  • This interlayer spatially decouples crystallization regulation from compositional modulation.
  • In situ diffusion of alkali metal ions (Li+, K+, Cs+) was utilized to reconstruct the buried contact and passivate defects.

    • Main Results:

    • The method resulted in stress-free crystallization, yielding dense, preferentially oriented perovskite films with void-free interfaces and improved compositional homogeneity.
    • The champion n-i-p perovskite solar cell achieved a PCE of 26.13%, with a high open-circuit voltage of 1.184 V and a fill factor of 83.81%.
    • The devices exhibited robust durability, retaining 93.7% of their initial performance after 1440 hours of continuous 1-sun irradiation at 65°C.

    Conclusions:

    • The triple-alkali interlayer strategy effectively manages cation dynamics for improved perovskite film quality.
    • This approach leads to highly efficient and stable perovskite solar cells.
    • The findings present a promising pathway for advancing perovskite photovoltaic technology.
