Metal Halide Perovskites
Metal halide perovskite materials have been considered as highly promising solution-processable alternative materials to conventional inorganic or organic semiconductors for optoelectronic applications. Excellent optoelectronic properties including long charge carrier lifetimes and diffusion lengths and high absorption coefficients have enabled the strong potential of perovskite based solar cells and LEDs. Also, as a light source with narrow full width half maximums (FWHM), metal halide perovskites are a promising future emitter material for next-generation high color-purity displays.
