The application belongs to the technical field of solar photovoltaic materials, and particularly discloses a preparation method of phosphorus-doped silicon master alloy. A double-temperature-zone horizontal furnace is used, and zinc phosphide is used as a dopant. A sealed quartz horizontal ampoule is arranged in the double-temperature-zone horizontal furnace. A graphite boat is arranged in the high-temperature section of the quartz horizontal ampoule, and polycrystalline silicon material is arranged in the graphite boat. A quartz crucible is arranged in the low-temperature section, and zinc phosphide is arranged in the quartz crucible. Different temperatures of the high-temperature section and the low-temperature section are set, and the temperature is kept for a period of time, and then the temperature is reduced to obtain the phosphorus-doped silicon master alloy. The speed of synthesizing the phosphorus-doped silicon master alloy is fast, the method is safe and reliable, the requirement for equipment is low, and the manufacturing cost of the phosphorus-doped silicon master alloy is greatly reduced.
