The cover picture shows a schematic image of in situ UV polymerization of polythiophene-conjugated polymer within a titanium dioxide nanotube array. By using this simple method, one can achieve high filling factors, synthesize well-ordered and well-aligned polymer chains, and effectively couple the electron-donating polymer to the surface of the electron-accepting semiconductor nanotubes. These advances are associated with improved light absorption, higher charge-carrier mobility, and efficient exciton separation. Compared to devices prepared by filling with pre-synthesized polymer, these solar cells exhibit significantly higher photocurrent, indicating that this methodology has the potential to improve the efficiency of hybrid organic–inorganic photovoltaics.
