  1. Competitive Absorption and Inefficient Exciton Harvesting: Lessons Learned from Bulk Heterojunction Organic Photovoltaics Utilizing the Polymer Acceptor P(NDI2OD-T2)

    Organic solar cellsbased on a small molecule donor and the polymer acceptor P(NDI2OD-T2) are fabricated and investigated. Through a comprehensive study of the optical and electronic properties of the blend films, the poor exciton diffusion length of P(NDI2OD-T2) is identified as the primary cause of the poor performance. In order to make non-fullerene acceptors competitive, the exciton diffusion length must be considered.

    The new concept of a biomimetic artificial hair cell using a flexible inorganic piezoelectric acoustic nanosensor (iPANS) is presented. A highly sensitive flexible piezoelectric sensor that responds to sound-driven vibrations of a thin silicone membrane is fabricated using a laser lift-off process. The iPANS shows remarkable capability to sense tiny vibrations caused by an external sound wave.

  3. Spectroscopic Evaluation of Mixing and Crystallinity of Fullerenes in Bulk Heterojunctions

    It is demonstrated that a combination of optical spectroscopy techniques such as UV–Vis absorption, steady-state and ultra-fast photoluminescence, electro­luminescence, and variable angle spectroscopic ellipsometry can be used to probe the degree of mixing of polymer:fullerene blends but also distinguishes between aggregation and crystallization of fullerenes. Both degree of mixing and crystallization have a huge impact on organic photo­voltaic device performance.

  4. Hierarchical Ordering of Quantum Dots and Liquid with Tunable Super-Periodicity into High Aspect Ratio Moiré Superlattice Structure

    A powerful new method is reported for fabricating complex lateral superlattice structures with 10 nm resolution, using the moiré fringe and secondary sputtering lithography. A large assortment of moiré superstructures can be easily fabricated by a simple rotation of the periodic layer. These superlattice structures widen the range of application of moiré patterns to not only the fields of photonics or optical characterization tools, but also to functional nano-materials trapping and ordering.

  5. Ultra-Thin Self-Assembled Protein-Polymer Membranes: A New Pore Forming Strategy

    Self-assembled membranes offer a promising alternative for conventional membrane fabrication, especially in the field of ultrafiltration. Here a new pore-making strategy is introduced involving stimuli responsive protein-polymer conjugates self-assembled across a large surface area using drying-mediated interfacial self-assembly. The membrane is flexible and assembled on porous supports. This approach diversifies membrane technology generating a platform for “smart” self-assembled membranes.
