| Abstract: | The photoelectric effect of the n-ZneCd1-x/Te (x = 0.01-0.04) single crystal electrode is generally rather low. However, the photocurrent is improved apparently with FeC13 dipping. Using Pb(NO3)2 as a dipping solution, both the fill factor and open-circuit voltage rise significantly. The conversion efficiency is enhanced to 10.2 %. The cyclic voltammetric curves for the electrodes treated under different conditions have been measured. It is found that the electrode dipped in FeC13 has the largest cathodic leakage current, and that there is a reduction peak at - 0.9V(vs. S. C. E.). The one dipped in Pb(NO3)2 has the beat stability. The modification mechanism of this electrode has been discussed in detail. |
