(National Academy of Sciences, 2018-05-02)From organic electronics to biological systems, understanding the role of intermolecular interactions between spin pairs is a key challenge. Here we show how such pairs can be selectively addressed with combined spin and ...
Perovskite/Colloidal Quantum Dot Tandem Solar Cells: Theoretical Modeling and Monolithic Structure Metal-halide perovskite-based tandem solar cells show great promise for overcoming the Shockley-Queisser single-junction efficiency limit via low-cost tandem structures, but so far they employ conventional bottom-cell ...
Order enables efficient electron-hole separation at an organic heterojunction with a small energy loss. (Springer Nature, 2018-01-18)Donor-acceptor organic solar cells often show low open-circuit voltages (VOC) relative to their optical energy gap (Eg) which limit power conversion efficiencies to around 12%. This energy loss is attributed, in part, to ...
