Dying to get inside : Charge recombination is retarded and dye aggregation is prevented in solar cells that contain the JK‐2 dye encapsulated in a cyclodextrin (CD) cavity (see picture). The β‐CD/JK‐2 device with a polymer gel electrolyte gave an overall conversion efficiency of 7.40 %, which is the highest value reported to date for DSSCs based on the organic sensitizers, and showed excellent stability.
