Perovskite Excitonics: Primary Exciton Creation and Crossover from Free Carriers to a Secondary Exciton Phase

Understanding exciton formation is of fundamental importance for emerging optoelectronic materials, like hybrid organic–inorganic perovskites, as excitons are the lowest‐energy photoexcitations in semiconductors, are electrically neutral, and do not directly contribute to charge transport, but can e...
