Symposium O

Advances in Perovskite Materials: Photovoltaics, Optoelectronics and Frontier Phenomena

(In collaboration with Aseanian Conference on Nano-Hybrid Solar Cells)

In recent years, lead halide perovskites have emerged as extraordinary optoelectronic materials in photovoltaic and light-emitting applications. Metal halide perovskites obtained from solution-processing, yield nearly defect free crystalline films, with long-range charge transport, high photoluminescence quantum yields, in a multitude of compositional and structural variants now offer a unique toolbox in which research communities explore a multitude of additional applications such as spintronics to bio-imaging. However, progress in device performance, stability, and reliability is essential. The major theme of this symposium is the fundamental understanding of the effect of processing conditions (e.g. relative humidity) and length scales (e.g. nanocrystal vs single crystal) on the optoelectronic properties that are urgently needed to advance the field towards highly efficient, stable, low toxic, and scalable devices. Material categories to be discussed include lead-based, lead-free, multi-dimensional perovskites, and nanostructured halide perovskites. Challenges in the areas of interfaces, defects, instabilities, and photo physics – on both experimental and theoretical levels should also be discussed. Understanding the mechanisms is the key to exploit the full potential of perovskites, and design the most efficient light emitting diodes, solar cells and lasers. Hot-carriers, multiband, or multiple exciton generation phenomena will also be discussed in context of the structure interaction through processes such as carrier scattering. The deliberations in this symposia will aid the advancement of hybrid perovskite devices through a clearer understanding of the fundamental processes governing these fascinating materials.
