The invention discloses a black silicon texturing process recycling an electrolyte solution. The black silicon texturing process comprises steps of settling metal particles and ionizing metal particles in sequence on a surface of a silicon sheet through an electrolytic method before and after texturing, wherein the step of settling the metal particles and the step of ionizing the metal particles are completed in the same electrolytic cell device, and the electrolytic cell device comprises a direct current power supply, an electrolyte and a cathode or an anode formed by a metal rod connected with the positive electrode and the negative electrode of the direct current power supply and the silicon sheet. In silicon sheet texturing process, the two steps of settling the metal particles and ionizing the metal particles on the surface of the silicon sheet are completed in the same electrolytic cell, so that electrolyzed silver ions in the electrolyte is always recycled, thereby lowering production cost and preventing water from being polluted.
