Abstract

A general and straightforward way of preparing few-nanometer-sized well-separated MAPbI_xBr_3−x (MA=methylammonium) perovskite photosensitizers on the surface of an approximately 1 μm thick mesoporous TiO₂ photoanode was suggested through a two-step sequential deposition of low-concentrated lead halides (0.10–0.30 m PbI₂ or PbBr₂) and methylammonium iodide/bromide (MAI/MABr). When those nanoscale MAPbI_xBr_3−x perovskites were incorporated as a photosensitizer in typical solid-state dye-sensitized solar cells (ss-DSSCs), it could be verified clearly by the capacitance analysis that nano-particulate MAPbI₃ perovskites play the same role as that of a typical dye sensitizer (MK-2 molecule) although their size, composition, and structure are different.
