The unique way in which light resonates in microspheres is applied by G. Konstantatos and co‐workers on page 139 to enhance the light‐harvesting efficiency of a solution‐processed PbS quantum dot–TiO 2 heterojunction. Depending on the relative position of the silica sphere monolayer with respect to the PbS–TiO 2 bilayer, different resonant modes can be coupled into the PbS absorbing layer, boosting the solar cell performance. The cover depicts a cross‐section of a microsphere layer completely embedded within PbS quantum dots on the nano crystalline TiO 2 film. The PbS quantum dot layer and the nano crystalline titania layer are coloured pink and violet, respectively.
