2D perovskitoids for enhanced photovoltaic stability

Two-dimensional (2D) perovskitoids have been developed with stable organic–inorganic structures that suppress cation migration, enhancing the long-term stability and efficiency of perovskite solar cells. Kanatzidis’s group synthesized 2D perovskitoids using large organic ammonium cations to inhibit cation migration, resulting in improved stability and efficiency in perovskite solar cells. Their research demonstrates significant long-term stability under harsh conditions and high-power conversion efficiency. However, the lack of comparisons with other passivation techniques, discussions on scalability and manufacturing costs, and real-world stability testing, highlighting the need for future research to address these gaps for practical applications.
