A Structurally Simple Polymer Donor Enables High-Efficiency Organic Solar Cells with Minimal Energy Losses.

Energy loss (Eloss) between optical energy gap (Eg) and open-circuit voltage (eVoc) sets efficiency upper limits for organic solar cells (OSCs). Nevertheless, further breaking the limit of Eloss in OSCs is challenging, especially via structurally simple materials in binary OSCs. Herein, a structurally simple non-halogenated polymer donor, namely PBDCT, is developed for realizing high-efficiency OSCs with record-breaking Eloss.

Deep-Learning-Assisted Understanding of the Self-Assembly of Miktoarm Star Block Copolymers.

The self-assemblies of topological complex block copolymers, especially the AB type miktoarm star ones, are fascinating topics in the soft matter field, which represent typical self-assembly behaviors analogous to those of biological membranes. However, their diverse topological asymmetries and versatile spontaneous curvatures result in rather complex phase separations that deviate significantly from the common mechanisms. Thus, numerous trial-and-error experiments with tremendous parameter space and intricate relationships are needed to study their assemblies.
