In this paper the output characteristics of PEC cell based on n-GaAs are studied.The influences of light intensity,chemical etching,concentration of redox system and ion modification on the conversion efficiency of PEC cell are observed.The conversion efficiency reaches 23.9% when the light intensity is low(9.61mW.cm^-2),with the electrode being repeatedly etched and modified by Ni²⁺ ion.The effect of pH on the flatband potential is determined.
