Unlocking High‐Performance in All‐Organic Solar Cells by the Development of Organic Electrodes with No Acid and High‐Temperature Treatment and the Effective Preparation Thereof on Organic Multilayer Films

open access: yesAdvanced Functional Materials, EarlyView.
The developed all‐organic solar cells achieve a power conversion efficiency of 8.7%, more than double the previous record. In addition, bioplastic substrates are used to produce environmentally friendly solar cells with an efficiency of 8.6%. These results are achieved by developing high‐performance organic electrodes without acid doping or high ...

Shape‐Stabilization of Phase Change Materials with Carbon‐Conscious Poly(hydroxy)Urethane Foams

open access: yesAdvanced Functional Materials, EarlyView.
Poly(hydroxy)urethane (PHU) foam, derivable from carbon dioxide (CO2) and bio‐based resources, is a promising material platform for shape‐stabilizing phase change materials (PCMs). We demonstrate the encapsulation of both paraffins and calcium chloride hexahydrate in PHU foam, achieving 48 stable thermal cycles by introducing 5 wt.% barium carbonate ...

High‐Fidelity Directed Self‐Assembly Using Higher‐χ Polystyrene‐Block‐Poly(Methyl Methacrylate) Derivatives for Dislocation‐Free Sub‐10 nm Features

open access: yesAdvanced Functional Materials, EarlyView.
The relationship between primary polymer structure and pattern quality in the directed self‐assembly of chemically modified polystyrene‐block‐poly(methyl methacrylate) derivatives is explored. The perpendicular lamellae are aligned, with a periodicity below 20 nm. No parallel orientations or dislocations form, and line patterns are well defined over an
