Problems solved by technology

[0008] Although researchers have made some progress in the preparation of perovskite materials, the existing liquid-phase and gas-phase methods have their shortcomings.
The disadvantage of the liquid phase method is that the spin coating process is difficult to control, which makes the performance of the grown perovskite material vary greatly; the amount of preparation materials is large, and the cost of large-scale pre...
