Organic-inorganic hybrid halide perovskites have emerged within the last few years as a revolutionary light absorber system, leading to solar cell efficiencies well above 16%. Interestingly, the recent progress in reduction the band gap of oxide based perovskites has also dramatically boosted the efficiency of oxide perovskite solar cells to close 10%. In addition to solar cell application, the fascinating optical and electronic properties of these perovskite systems have enabled their usage for various electronic devices including light emitting diodes, photodetectors, transistors, and memristors. Despite these remarkable progresses associated with perovskites, there are still many fundamental questions that need to be addressed at both material and device levels. Further improvements are required to advance our understanding on the material effects on the fundamental physical and chemical processes that are important to device operations.
This symposium will cover a wide range of topics on the recent technological development and scientific issues (e.g., crystallization, defect, interface, stability, characterization, modeling, photophysics and upscaling) of the perovskite materials for photovoltaic and other electronic device applications. The goal of this symposium is to bring scientists and engineers together to share their knowledge and views on the challenges and future directions for producing low-cost and high-performance perovskite based electronic devices with good reliability.
