| abstract |
The invention relates to a perovskite LED for AC driving and a preparation method thereof, comprising an anode layer, a hole transport layer, a perovskite light-emitting layer, an electron transport layer and Cathode layer; AC power is applied to both ends of the cathode layer and the anode layer to realize an AC-driven perovskite LED. Both the hole transport layer and the light-emitting layer of the present invention can be prepared by a solution method, the operation is simple, and the production cost can be reduced to a certain extent; by changing the components of the perovskite material, various colors of light emission of the device can be realized; Adjusting the brightness of perovskite LEDs. |
