Metal-organic　frameworks　(MOFs)　have　been　used　in　the　area　of　photovoltaic　devices　via　a　novel　approach　proposed　here　for　the　first　time.　Hierarchical　ZnO　parallelepipeds　were　prepared　from　a　MOF　precursor,　which　could　then　act　as　an　effective　light　scattering　layer　in　dye-sensitized　solar　cells,　leading　to　significantly　improved　cell　performance.
