The synthesis of highly crystalline perovskite BaSnO 3 nanoparticles for use as photoanode materials in dye‐sensitized solar cells (DSSCs) is reported, and the photovoltaic properties of DSSCs based on BaSnO 3 nanoparticles (BaSnO 3 cells) are demonstrated. The resulting DSSCs exhibit remarkably rapid charge collection and a DSSC fabricated with a BaSnO 3 film thickness of 43 µm leads to a high energy conversion efficiency of 5.2 %, which is one of the highest reported for ternary oxide‐based DSSCs. More importantly, the BaSnO 3 cells show superior charge collection in nanoparticle films compared to TiO 2 cells and could offer a breakthrough in the efficiencies of DSSCs.
