Abstract：

NH4TiOF3　nanobricks　are　prepared　by　a　one-step　hydrothermal　route　and　then　are　made　into　paste.　The　NH4TiOF3　are　in　situ　topologically　transformed　into　anatase　TiO2　hollow　nanobricks　via　a　boric　acid　treatment　process　after　the　paste　is　screen-printed　onto　FTO　glass　as　a　scattering　layer　for　DSSCs.　The　cell　with　scattering　layer　exhibits　a　high　photovoltaic　conversion　efficiency　of　8.09%,　which　is　24.8%　higher　than　that　of　the　cell　composed　of　bare　nanocrystalline　TiO2　(6.48%).　After　a　series　of　characterization,　the　higher　specific　surface　area　and　the　superior　light-scattering　ability　of　hierarchical　TiO2　hollow　nanobricks　are　proved　to　be　the　main　facts　for　the　enhanced　efficiency.　©　2019　Elsevier　B.V.
