Article Synopsis
- The study investigates how hydrogen loading in an electrochemical palladium membrane reactor (ePMR) is affected by factors like current density and electrolyte concentration, finding that hydrogen loading increases with these factors but levels off at about 0.92 in specific conditions.
- The researchers utilized measurements of hydrogen fugacity and conducted both experimental and computational studies to validate their findings, including electrochemical hydrogen permeation and finite element analysis.
- The research also explores how hydrogen loading influences the free energy of palladium-hydrogen alloy formation, demonstrating that the ePMR can drive reactions like the reduction of carbon dioxide with a favorable energy change.
Fused-ring core nonfullerene acceptors (NFAs), designated "Y-series," have enabled high-performance organic solar cells (OSCs) achieving over 18% power conversion efficiency (PCE). Since the introduction of these NFAs, much effort has been expended to understand the reasons for their exceptional performance. While several studies have identified key optoelectronic properties that govern high PCEs, little is known about the molecular level origins of large variations in performance, spanning from 5% to 18% PCE, for example, in the case of PM6:Y6 OSCs.

Essential properties of organic donor:acceptor bulk heterojunction blends and electrode materials, required for the combination of simultaneous high power conversion efficiency (PCE) and average visible transmittance of photovoltaic devices, are presented from the materials science and device engineering points of view. Aspects of optical perception, charge generation-recombination, and extraction processes relevant for semitransparent OSCs are also discussed in detail.
