In this case the researchers worked with methylammonium lead iodide, a common material in perovskite PV research.
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.
On a less optimistic note, researchers of the Energy Materials and Surface Sciences Unit at the Okinawa Institute of Science and Technology Graduate University have been studying the short lifespan of methylammonium lead iodide perovskite ([MAPbl.
We found that these PSCs are self-exposed to iodine vapor at the onset of degradation, which led to accelerated decomposition of the perovskite material into lead iodide," Wang explains.
