A novel core–shell nanostructured WO3is investigated in detail and shown to work successfully as an electron transporting material in hybrid perovskite solar cells. A thin TiO2shell reduces charge recombination while highly textured single-crystal WO3nanostructures promote fast electron transport leading to an efficiency above 11%.
