Nanowires in the sun : Hydrothermal synthesis yields homogeneously tantalum‐doped titania nanowire arrays on transparent conducting oxide substrates. The methodology should allow doping of titania nanowires with different transition metals. This advance in materials synthesis translates into enhanced device performance, as demonstrated by dye‐sensitized solar cells with very high open‐circuit photovoltage (see picture).
