The invention discloses a preparation method of a perovskite type high-voltage solid solution, and belongs to the technical field of piezoelectric materials. The preparation method comprises the following preparation steps: adding chlorobromomethane and trimethylamine into an acetonitrile solution to obtain a trimethylchloromethylamine bromide solution; adding an inorganic substance into a methanol solution to obtain a methanol suspension of the inorganic substance, stirring and dissolving a trimethyl chloromethylamine bromide solution and the methanol suspension containing the inorganic substance to obtain a clear methanol solution containing TMCM-CdBrCl2, and evaporating to obtain TMCM-CdBrCl2 colorless bulk crystals; then carrying out ball milling treatment to obtain molecular piezoelectric material micro powder; mixing the molecular piezoelectric material micro powder with a new methanol solution to obtain a clear methanol solution containing the molecular piezoelectric material micro powder; and sucking
