摘要：

Electron injection from optically excited dye molecules into the depletion layer of polycrystalline n-TiO2 electrodes is measured as photocurrent. The characteristic shape of the photocurrent transients has a point of inflection and is controlled by the complete filling of deep traps. The rate equations for the Shockley-Read trapping process are solved numerically for the case of high injection levels, and the shape of the transients is simulated.
