<![CDATA[The study of nanomaterial for solar energy conversion via zinc oxide (ZnO) nanostructure has grounded for decades. Many reports shown that ZnO nanorod can substitute the expensive titanium-based as the working electrodes of dye-sensitized solar cell (DSSC). The main lack of ZnO-based to the titanium-based is the low charge carrier. Fortunately, this issue can be solved by metal doping to the ZnO nanorod. The dopant can improve the physical and optical properties, such as increasing charge carrier and effective surface area. These properties can lead higher efficiency of DSSC in converting the light to electricity. In this paper, we enhance the ZnO nanorod properties through the doping of aluminum (Al). For obtaining optimum results, we varied the dopant concentration of 1, 1.5, 1, and 3.0%. The Al-doped ZnO nanorod was grown by a seed-mediated hydrothermal method at 90oC for 8 hours. The physical properties were analyzed by field emission scanning electron microscopy (FESEM) and EDX, while the photovoltaic properties were analyzed by J-V curve analysis. An improvement of photovoltaic performance up to 200 % is obtained by the ZnO nanorod with 1.0% Al-doped concentration.]]>
