SISF2024 signifies the 12^th installment of this esteemed forum, with the previous edition in 2015 having been canceled due to the MERS outbreak and the 2020-2021 event being postponed due to the COVID-19 pandemic. The organizing committee takes great pride in extending a warm invitation to distinguished scientists from across the globe to participate in SISF2024. In SISF 2024, we will discuss in depth fundamentals and applications of halide perovskites for use in territory and space.
