Paudel et al. ( pp. 924–927 ) fabricated and studied solar cells based on the distributed nanocoax architecture by depositing amorphous silicon (a‐Si) as photovoltaic medium on the arrays of aligned multi‐wall carbon nanotubes (MWCNTs). These inexpensive cells demonstrate an initial efficiency of 6.1% that can be further enhanced by increasing the nanocoax density per unit area and improving the amorphous silicon quality. The cover image shows a false‐color photograph of a nanocoax cell (size of a single coax is ca. 1 µm) and the curves of a I–V plot demonstrating the efficiency of a solar cell fabricated by employing these CNTs compared to a planar cell. In the sketch, the CNTs are shown in light grey, a‐Si in red, and indium tin oxide in yellow.
