Device architectures and geometry parameter indications of five different structured surfaces.
(a) Structured surface A: film stack. (b) Structured surface B: structured surface with CH3NH3PbI3 grating. (c) Structured surface C: structured surface with TiO2 grating. (d) Structured surface D: structured surface with SiO2 grating. (d) Structured surface D: structured surface with TiO2 grating and SiO2 grating. The black dash line indicates the normal direction of the top interface.
