Electrochemical Photovoltaic Cells: II. VI Compound Thin-Film Electrodes. Quarterly Technical Progress Report No. 3, December 1980-February 1981

摘要

Activities are reported in two main research areas, namely, CdSe/sub 1-x//Te/sub x/ thin film electrodes and evaluation of the effect of introduction of Zn into the near surface region of CdSe electrodes on the resultant electrode performance. The efficiency of CdSe/sub 1-x//Te/sub x/ electrodes deposited by the concurrent vacuum evaporation of Cd, Se and Te has been improved to > 5%. The beneficial effect of ZnCl sub 2 treatment on the output parameters of CdSe thin films has been shown repeatedly and several electrodes with eta > 6% produced. The main role of the Zn treatment is a suppression of dark current in the cathodic (forward bias) direction leading to higher V/sub oc/ in all cases and in increased fill factor in some instances.
