The kinetics of interracial processes of CdSe thin film electrode before and after surface modification of 1, 1'-di linolene ferrocenyl L-B films have been studied in K₄Fe(CN)₆ solution by Intensity Modulated Photocurrent Spectroscopy (IMPS).Potential dependence of surface state relaxation time (T_s), steady state photocurrent (I_s), collection coefficient of minority carriers (G_o), rate constant of photocorrosion (K_cr), and density of surface state (N_ss) were determined in terms of frequency response analysis of IMPS plots.
