Hierarchical TiO2/ZnO nanospheres : The cover image shows a schematic of synthesized TiO 2 nanospheres and the changes brought about by the incorporation of ZnO. The ZnO/TiO 2 nanospheres are aggregates of crystallites of ZnO that are uniformly dispersed over TiO 2 to make heterojunctions. This study describes the different doping percentages tested with the optimized value of 1 % showing the best efficiency and the highest porous surface area among the samples. The spherical morphology of the synthesized material provides good light harvesting by efficiently trapping electrons. Moreover, this arrangement leads to increased electron carrier density, leading to highly efficient solar cells. More details can be found in the Full Paper by Kiran P.
