Description

technical field [0001] The invention relates to a perovskite light-emitting device, in particular to an integrated self-powered perovskite light-emitting integrated device. Background technique [0002] Perovskite materials quickly stand out from many new photovoltaic materials due to their huge advantages such as suitable bandgap width, high extinction coefficient and low raw material cost. The efficiency of solar cells based on perovskite materials increased from 3.8% in 2009 It climbed up to 23.3% in 2018, and the ultra-high photoelectric conversion efficiency has also greatly opened up the gap with other new photovoltaic devices such as CZTS, DSSC and OPV, and is gradually approaching the 26.6% efficiency of monocrystalline silicon. Although perovskite materials have achieved remarkable success in the field of solar technology, in fact, before perovskite materials are applied to photovoltaic devices, they have already been used in many fields such as electroluminescence,...
