Single-junction organic solar cells with over 19% efficiency enabled by a refined double-fibril network morphology

Nature Materials, Published online: 05 May 2022; doi:10.1038/s41563-022-01244-yThe morphology of donor–acceptor blends in organic photovoltaics dictates the efficiency of the exciton dissociation and charge diffusion, and thus the final device performance. Here, the authors show that filament assembly helps to maximize the output, further enabling a...

Chirality tweaks spins in tellurium

Nature Materials, Published online: 03 May 2022; doi:10.1038/s41563-022-01228-ySpins become polarized along their momenta when travelling through chiral tellurium nanowires. The signs of chirality and current determine the orientations of polarized spins while the spin density can be tuned by electrical gating, current and external magnetic field.
