S3: Materials Challenges in Perovskite and Next Generation Solar Cells

Recently, advanced materials and technologies for perovskite and next-generation solar cells have been exploited to develop economically viable, high-performance solar cells. Organo-metal trihalide perovskites have revolutionized the field of thin film solar cells due to their meteoric rise of power conversion efficiency (PCE) of a record value 22.1%. These materials exhibit salient properties such as strong light absorption from the visible into the near-infrared spectral region, long carrier diffusion length, and tailorable optoelectronic properties through compositional engineering of halides and cations. These properties are subservient to the formation and nature of the crystals, morphology, and growth. One of the most fantastic features of organo metal trihalide perovskite is its ability to self-assemble between precursors of solid-solid, vapour-vapour, vapour-solid, co-solution, solid-solution phases into high quality crystalline powder or thin films at near ambient conditions. Despite the high efficiency and excellent opt-electronic properties, the biggest problem of organo-metal trihalide perovskite is stability under heat and light soaking conditions. This symposium will focus on the key issues and phenomena that are at the frontier of understanding and materials development in perovskite solar cells and next generation solar cells, addressing, but not limited to, the following topics
