Quintuple‐shelled SnO 2 hollow microspheres are prepared by a hard‐template method. DSSCs constructed with SnO 2 multi‐shell photoanodes show a record photoconversion efficiency of 7.18% due to enhanced light scattering. SnO 2 hollow microspheres that are utilized as a scattering layer on top of P25 films increase the DSSC photoconversion efficiency from 7.29% to 9.53%.
