Now, the lab of Mohammad Khaja Nazeeruddin at EPFL Valais Wallis, with colleagues at the University of Cordoba, has discovered that they can improve perovskite stability by introducing the large organic cation guanidinium (CH6N3+) into methylammonium lead iodide perovskites, which are among the most promising alternatives in the group today.
