Through cyanation on quinoxaline-based small-molecule acceptors (SMAs), BQx-CN with a mono-cyanide group exhibits down-shifted energy levels and stronger intermolecular stacking for rapid charge transfer and transport. When employed in organic solar cells (OSCs), the BQx-CN-based devices yield a higher efficiency of 18.8%, which is one of the highest...

Coexisting C6H7O6 −/C6H5O6 − redox couple in aqueous electrolyte with sodium isoascorbate as a self-deoxidizing and self-dehydrogenating additive spontaneously captures dissolved oxygen and eliminates generated hydrogen. Antioxidant Interfaces are created on the Zn anode due to the formation of a ZnCO3-dominated solid electrolyte interphase, which...

A novel discontinuous interconnection based on a dashed P2 contact is developed to minimize the efficiency losses from cell to module. In this way, it is possible to achieve a record geometrical fill factor of 99.6% (active area divided by the sum of active area and interconnection area), without inducing any resistive losses, achieving a minimodule...

This work reports a kind of 1D coordination polymers based on nonprecious metals and natural products, which show an impressive overpotential of 190 mV at 10 mA cm−2 and an ultralow Tafel slope of 28 mV dec−1. The inexpensive and sustainable raw materials can reduce the OER catalyst cost by 4 orders of magnitude. Abstract The oxygen evolution...

Printing perovskite solar cells (PSCs) offers scalability and cost-efficiency for industrial applications. However, challenges persist in achieving stability, uniformity, and scalability. This review assesses printing techniques under ambient conditions and explores environmentally sustainable alternatives. Abstract The demand for cost-effective...

The binders used for lithium-ion battery cathodes are still based on fluorinated polymers and are processed with toxic organic solvents. Herein, novel binders inspired by polymerizable surfactants are presented as tailorable, water-processable, fluorine-free alternatives compatible with state-of-the-art LiNi0.6Mn0.2Co0.2O2 (NMC622) cell chemistry....
