TL;DR: The room-temperature structure of lysozyme is determined using 40000 individual diffraction patterns from micro-crystals flowing in liquid suspension across a synchrotron microfocus beamline.

TL;DR: In this article, the solvent vapour annealing (SVA) time for the photovoltaic layer was optimized to obtain a balance between its crystallization and phase separation, resulting in a record power conversion efficiency (PCE) of over 28% under fluorescent lamps of 1000 lux.

TL;DR: In this paper, a critical review of the degradation mechanisms of non-fullerene acceptors compared to fullerene small molecule acceptors is presented, as well as the very different roles they play upon the charge carrier generation and recombination kinetics and the resulting solar cell stability.

TL;DR: In this article, the role of photo-oxidation of PCBM derivatives in limiting the stability of organic solar cells was quantitatively studied, showing that a minor fraction of photooxidised PCBM, induced by short exposure to either solar or ambient laboratory lighting conditions in air, consistent with typical processing and operating conditions, is sufficient to compromise device performance severely.

TL;DR: In this paper, the important role of molecular structure and conformation in NFA photostability in air is investigated by comparing structurally similar but conformationally different promising NFA: planar O•IDTBR and nonplanar O'IDFBR, and a three-phase degradation process is identified: i) initial photoinduced conformational change (i.e., torsion about the core-benzothiadiazole dihedral), induced by noncovalent interactions with environmental molecules, ii) followed by photo−oxidation and fragmentation, leading
