The design of hybrid organic-inorganic halide perovskite is envisioned as the future of lightweight and efficient photovoltaic devices. Despite the multiple advantages of perovskite materials, a main drawback that is currently slowing down their use in industrial applications is their relatively low long-term stability. My research focuses on understanding the physical mechanisms hidden behind this low stability by using highly surface-sensitive techniques and proposes strategies to mitigate it.
