Summary: | The invention provides a perovskite solar cell and a preparation method thereof. The perovskite solar cell comprises a transparent substrate arranged in a stacked layer, a negative electrode, a down-conversion luminescent layer, an electron transfer layer, a perovskite layer, a hole transport layer, an up-conversion luminescent layer and a positive electrode, wherein the down-conversion luminescent layer is arranged between the negative electrode and the electron transport layer. The perovskite solar cell has the advantages that the down-conversion luminescent layer and the up-conversion luminescent layer are respectively additionally arranged on the upper surface and the lower surface of the perovskite solar cell, so that ultraviolet light and infrared light which cannot be absorbed by the perovskite solar cell can be converted into visible light, the utilization rate of sunlight is increased, the photoelectric conversion efficiency of the perovskite solar cell is further improved, and the long-term stabilit |
