Fluorinated Aniliniums Lead To A Breakthrough In Perovskite Solar Cells

Ecole Polytechnique Fédérale de Lausanne researchers have found a way to significantly improve the operational stability of perovskite solar cells at high temperatures, which is necessary for their use in terawatt power grids. Perovskite solar cells (PSCs) have gained attention for their high power-conversion efficiencies and low-cost solution processing. However, ensuring their stability at high temperatures has been a challenge, as the points of contact between their different layers (“interfaces”) are susceptible to…
