Aluminum doped ZnO nanorods with various percentage concentrations of Al 0%, 0.5%, 1%, 1.5%, and 2% have been successfully grown on FTO using hydrothermal method at a temperature of 90° C for 8 hours. The FESEM images showed that the geometrical shape of all the sampels was nanorods with hexagonal face shape. The Al 1% doped sample produced the highest density, thickness and uniformity of ZnO …
