On page 5538, Y. Lei and co‐workers present photoelectrochemical applications of well‐ordered CdTe/TiO 2 heteronanostructure arrays prepared by template‐directed approaches, demonstrating that modulating the diameter of CdTe/TiO 2 heteronanostructure arrays improves the solar energy conversion efficiency. Compared to photoanodes with only TiO 2 nanotube arrays, the CdTe/TiO 2 heteronanostructure electrodes possess a dramatic performance optimization. Subsequent characterizations reveal that the CdTe core is responsible for utilizing photons, while the TiO 2 shell is beneficial for core protection and promoting charge separation in the structures.
