Hybrid perovskite materials have evolved to achieve high power conversion efficiency as solar cell absorber, reaching more than 22% efficiency that competes with Si solar cells. This symposium focuses on the latest advances in preparation and characterisation of organic inorganic hybrid perovskite materials and their applications to high performance photovoltaic and optoelectronic devices. In material preparation, new methods in solution process will be discussed in addition to vacuum and vapour phase deposition methods in aims to realise high quality perovskite films by low cost manufacture process. Photophysical properties of the perovskite film including carrier transport mechanism, defect trapping phenomena, and photoluminescent (PL) behaviour are discussed in relation to device performance. Perovskite-based devices are also discussed in this symposium, which include photovoltaic cell, optoelectronic device, photodetector, and light emitting and laser devices. Here, important aspects of performance are not only efficiency but also stability and durability in practical use. Theoretical modeling study to explore new hybrid materials to improve efficiency and stability is also in the scope of the symposium.
