Increasing LED lighting efficiency by combining nitrides and perovskites
Group III-Nitride materials are excellent semiconductors that have band gaps spanning a very large spectral range. However, their use in light-emitting diodes (LEDs) and lasers operating in the visible spectrum has remained limited. The EU-funded PEROGAN project will combine III-Nitrides with lead halide perovskites – crystal semiconductors that have recently shown great promise for optoelectronics. The project aims to create hybrid devices that combine the excellent electrical properties of III-Nitrides with lead halide perovskites having high quantum efficiency and tuneable properties in the visible spectrum. If successful, it will lead to the development of high-efficiency LEDs with a high colour rendering index for solid-state lighting and display applications.
