Problems solved by technology

However, the chemical structure of Spiro-OMeTAD is complex, the synthesis route is long, the price is expensive, and the hole mobility of the material is low, which leads to the low energy conversion efficiency of perovskite solar cells.
Usually, p-type doping with lithium bis(trifluoromethylsulfonimide) (LiTFSI), tert-butylpyridine (t-BP), etc. is required to improve the hole mobility, but this type of doping will cause the battery Device performance is unstable and materials are expensive
