The invention discloses a structure of a flexible perovskite solar cell and a preparation method thereof. The solar cell structure proposed by the present invention is composed of a flexible substrate, a metal bottom electrode, a doped electron collection layer, a perovskite layer, a hole transport layer and a transparent conductive polymer top electrode, in order from bottom to top. The battery structure proposed by the present invention can use a low work function interface modification layer and a doped electron collection layer as the cathode modification layer to avoid the use of metal oxides, making low-temperature preparation possible. Using metal as the bottom electrode, the resistance value is much smaller than that of common ITO, which can reflect light and can be used in the production of large-area batteries. The battery structure of the present invention can be applied to power generation devices that cannot use rigid materials such as curved walls and car tops, and can be bent without affecting device performance. It has broad application prospects for realizing flexible large-area perovskite batteries.

The invention discloses a method for intensifying the sintering of high-proportion fine-grained materials by multi-medium gas injection. The method involves mixing, granulating, distributing, igniting and sintering raw materials such as fine-grained iron ore, flux, high-combustion active fuel, conventional fossil fuels and ore returns in sequence, and spraying into the sintering material surface during sintering Mixed gas medium composed of gas and water vapor. This method optimizes the gas permeability and thermal state of the material layer by adjusting the characteristic parameters and proportion of fuel with high combustion reactivity, coupled with the adjustment of the concentration of multi-medium gas injection, the coverage area, and the relative volume percentage of gas and water vapor, so as to achieve high Intensification of proportional fine-grained material sintering.
