摘要: Abstract Quantum Dot (QD) sensitized solar cells due to their high potential have attracted tremendous attention become a low cost and reliable substitute for the fossil fuels. This study reports fabrication optimization of CdS QDs connected ZnO nanowires (NWs) which were grown by hydrothermal method. Optimization process was done using set experiments, designed systematically extract best values. ZnS shell-like synthesized on surface NWs successive ionic layer adsorption reaction approach. The effect different components charge transfer studied. cell with NW/CdS(4C)/ZnS(3C) as photosensitizer, CuS counter electrode Na 2 S 0.6 M, 0.2 M KCl 0.4 M in methanol/water (7:3) electrolyte exhibited performance efficiency 0.419%. Although increasing dot thickness supposed improve performance, defects occurred during growth, large mismatch core shell, decay cell's efficiency.
