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.
