| Abstract: | In this paper the complex collection efficiency figures of n-InP in Fe~(8+)/Fe~(2+) solution are determined with light pulse technique by fast Fourier transformation using microcomputer. It is a half circle at fourth quadrant. According to theoratical model three photoelectrochemical kinetic parameters are calculated from the position of circle centre, the radius of circle and the characteristic frequency. Influences of the electrode potential and the light intensity on those parameters are dermined and the results are discussed. |
