Understanding the Interplay Between Thermal Activation, Diffusion, and Phase Segregation of Molecular Dopants Blended with Polymeric Semiconductors

open access: yesAdvanced Electronic Materials, EarlyView.
The use of air stable but thermally labile molecules provides an efficient strategy for the N‐type doping of organic semiconductors with relatively low electron affinities. Design criteria for efficient dopants should also take into account diffusion and phase segregation that cannot be decoupled from thermally activated doping.

Asymmetric Acceptor Featuring Fused‐Imidazole Central Core Enabling Organic Solar Cells with 19.4% Efficiency

open access: yesAdvanced Energy Materials, EarlyView.
Asymmetric Y‐acceptor BTQT‐4F featuring innovative fused‐imidazole central linkage, is successfully developed by 2D π‐expansion strategy. The decent power conversion efficiencies (PCEs) of 18.22% and 19.40% are achieved in the PM6:BTQT‐4F binary and PM6:BTP‐eC9:BTQT‐4F ternary organic solar cells (OSCs), respectively.

Discerning Performance Bottlenecks of State‐of‐the‐Art Narrow Bandgap Organic Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
This work quantitatively discerns the loss mechanisms of state‐of‐the‐art low‐bandgap organic solar cells based on BTPV‐4X‐eC9 acceptors. Compared to PM6:Y6, geminate recombination of charge transfer (CT) states governs photocurrent losses. This relates to conformational freedom of these acceptors that restricts their aggregation, and also counteracts ...

Low‐Cost, High‐Efficiency Organic Solar Cells Based on Ecofriendly Processing Solvent

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
A low‐complexity, cost‐effective donor material, PTQ10, combined with the high‐efficiency acceptor materials, BTP‐eC9 and Y6, demonstrates excellent performance with the ecofriendly solvent o‐xylene (XY) instead of the traditional chloroform (CF) for the spin‐coating method.
