Abstract

The addition of metal dopant into ZnO nanocrystals may induce changes both electronic and crystal grow properties, which later modify its photoactivity and surface physico-chemistry properties, improving its photovoltaic performance in DSSCs application. Here we report a dramatic distortion in the crystal grow orientation of ZnO in the presence of ruthenium ion dopant, changing the crystal morphology from fine hexagonal shape nanorod to starfruit-like shape nanorod. We found that such modification in the ZnO nanostructure enhanced photovoltaic properties, in typical case increased up to two times increment to 0.43%, compared to pristine hexagonal nanorod sample (0.2%). The present results may provide alternative strategy to augment the photoactivity of the nanostructure. High performance DSSC device will then be obtained when optimized fabrication procedure is implemented.
