Organometal halide perovskite-based optoelectronic devices

Abstract

Abstract Organometal halide perovskites are potential optoelectronic materials due to high solar cell efficiencies of 22.1% and light-emitting diodes with wide color gamut emission and external quantum efficiencies of 8%. Although perovskite light-emitting devices are still in research and development phase, in only a few years perovskite-based light emitting diodes have already exceeded the performance of organic light-emitting diodes. Further progress in this new material will depend on material optimization and development of scalable deposition process. Here, the advancements in perovskite-based optoelectronic devices at National university of Tainan are presented.
