The application discloses a method for improving the gettering efficiency of crystalline silicon, comprising the following steps: (1) removing the PSG layer after phosphorus diffusion, and testing the phosphorus concentration distribution, the phosphorus diffusion layer depth, the silicon wafer thickness and the metal impurity content ratio before and after gettering; (2) obtaining a first equation by using the continuity equation before and after metal impurity gettering and the existing form of metal impurities in the heavily doped phosphorus layer; (3) substituting each parameter into the first equation to obtain a value related to the segregation coefficient; (4) converting the phosphorus concentration distribution into the depth distribution of phosphorus diffusion with time, substituting into the first equation to obtain a gettering kinetics curve; (5) substituting the influence factor into the gettering kinetics curve to obtain a modified phosphorus gettering kinetics curve for predicting the phosphorus gettering efficiency; and (6) comparing the predicted phosphorus gettering efficiency with the gettering efficiency under the same thermal history in actual production to guide the process optimization of phosphorus gettering. By using the application, the gettering effect can be significantly improved.
