  Resonant cavity phosphor

  Phosphor efficiency can be improved via materials development or structural engineering, the latter only begun lately. Here the authors propose and investigate simple vertical resonant cavity as a platform for nanostructurally engineered phosphor.

  Roll-to-roll fabrication of touch-responsive cellulose photonic laminates

  Self-assembled structures are typically demonstrated on small scales under well-controlled lab environments. Here, the authors present a roll-to-roll process for the continuous manufacturing of square-meters of self-assembled cellulose-based mechano-chromic films and demonstrate the recording of pressure profiles generated by foot-imprints in real time.

  Ohmic transition at contacts key to maximizing fill factor and performance of organic solar cells

  The importance of ohmic contacts for organic solar cells has been recognized, but how the transition to ohmic behavior occurs is unknown. Tan et al. show that this transition happens separately beyond Fermi-level pinning, when the interfacial contact resistivity becomes sufficiently low.

  High-efficiency polymer solar cells with small photon energy loss

  Maximising short-circuit current density and open circuit voltage in polymer-fullerene solar cells is a critical issue. Here, the authors use an aphthobisoxadiazole-based polymer and observe a low photon energy loss of 0.5 eV, with an open-circuit voltage of 1 V and power conversion efficiency of 9%.
