Problems solved by technology
However, due to the explosiveness and high toxicity of hydrazine, the application of this method is limited.
The Hillhouse research group of the University of Washington in the United States proposed a low-hazard precursor solution solution based on dimethyl sulfoxide solvent, but due to the existence of cationic redox reactions in the solution, the improvement of the efficiency of the prepared solar cells was limited.
