摘要： The invention relates to a perovskite tandem solar cell based on a tunneling layer of two-dimensional layered metal carbides and metal nitrides, the tunneling junction composite layer is prepared by using two-dimensional layered metal carbides and metal nitrides, a dense layer is arranged on one side of the tunneling junction composite layer, and a transport layer is arranged on the other side. The two-dimensional layered metal carbide and metal nitride materials are selected from graphene, Ti3C2Tx, Mo2CTx, V2CTx, Nb2CTx and Ti2CTx. The tunneling junction structure of the invention can effectively reduce the light loss in the tandem solar cell and the interface recombination of the tandem cell, which can significantly improve the photocurrent generation and charge transfer of the perovskite/perovskite tandem solar cell, and improve the power conversion efficiency of the perovskite/perovskite tandem solar cell.

摘要： The present disclosure relates to the field of inorganic non-metallic optoelectronic functional materials, and discloses wet-resistant fluoride red phosphor and preparation and application thereof, and a white light LED device. The fluoride red phosphor is a core-shell structure: the core is Mn4+ doped fluoride red phosphor, and the chemical structural formula is A2B1-xF6:xMn4+, herein A is at least one of Li, Na, K, Rb, and Cs, B is at least one of Ti, Si, Ge, Zr, and Sn, and 0≤x≤0.4; and the shell is a cubic perovskite-type compound, and the chemical structural formula is CMgF3, herein C is at least one of Li, Na, K, Rb, and Cs. The present disclosure uses CMgF3 generated as a coating waterproof layer, to form the A2B1-xF6:xMn4+ core-shell structure of which the surface is coated by CMgF3, and a wet-resistant problem of the fluoride red phosphor is overcome.
