Cs-based Quasi-2D Perovskite: Toward Efficient Perovskite Light-Emitting Diodes with Blue Emission

黎振超  陈梓铭  叶轩立  
【摘要】:In recent years, metal halide perovskites have shown promising potential in a series of optoelectronic applications such as solar cells, light-emitting diodes(LEDs), photodetectors and lasers~([1,2]). However, blue perovskite LEDs currently still suffer from inferior performance. Therefore, a breakthrough in thin-film perovskite LEDs with blue emission is an urgent target in this field. In our recent work~([3]), we push up the efficiency of blue perovskite LEDs combining three key strategies: composition engineering, dimensional engineering and modulation of recombination zone position. Firstly, through composition and dimensional engineering, we prepare quasi-two-dimensional perovskite thin films with improved blue emission, taking advantages of reduced trap density and enhanced photoluminescence properties. Secondly, we find a vertically non-uniform distribution of perovskite crystals in the PEDOT:PSS/perovskite hybrid film. Through modulating the position of the recombination zone, we activate the majority of quasi-two-dimensional perovskite crystals, and thus demonstrate highly efficient blue perovskite light-emitting diode with emission peak at 480 nm, luminance of 3780 cd m~(-2) and external quantum efficiency of 5.7%.
