The Front Cover image shows a new and efficient cone ‐calix[4]arene‐based dye (Calix‐3) with multiple donor–π–acceptor (D–π–A) moieties used in dye‐sensitized solar cells (DSSCs). The conversion efficiency of Calix‐3 is above 5 % under standard global 1.5 solar conditions. This compares well with a device using rod‐shaped dye M‐3 with a single D–π–A chain, which has an efficiency of 3.56 %. The cone ‐calix[4]arene‐based dyes offer higher molar extinction coefficients, longer electron lifetimes, better stability, and stronger binding ability to a TiO 2 film. To the best of our knowledge, this is the first example of the use of calixarene‐based sensitizer in efficient dye‐sensitized solar cells.
